Method 1 – Window Condensation Solved!
Welcome back to the window dog calm today were coming to you from this beautiful old house just outside of. The french quarter in new orleans now its a wonderful day here today but it is a little chilly in. Fact i think its the coldest day so far this year that makes it the perfect day to talk about. Condensation that might form on your windows when it first starts to get cold outside so weve been at this.
For many years and every year when it first starts to get cold well get inquiries from folks all over. The country with condensation on their windows now sometimes these are people with new windows sometimes theyre people with old. Windows but when it first starts to get cold is when everybody starts to get worried about condensation so what. Were gonna do is look at whats going on here were gonna look at how you can reduce or eliminate. The chances of condensation forming on your windows and well look at what factors you should consider when ordering new.
Windows to try to prevent condensation from performing so to start off i think its helpful to understand what causes. Condensation to form on your windows basically all the air has moisture in it and warm air can hold more. Moisture than cold air so as warm moist air cools down at some point it reaches a temperature where it. Can no longer hold as much moisture as it has in it that moisture then condenses turns from a gas. Into a liquid and forms water droplets under whatever the coldest surface is around generally speaking if you look at.
A wall the coldest surface is going to be the perimeter of an insulated glass unit or even i suppose. A non insulated glass unit the perimeter of the glass is going to be the coldest spot and thats where. Youll generally see the condensation start to form here we can look at an infrared camera view of my house. You can see here the coldest section of this wall is the perimeter of these insulated glass units thats just. How it works so if youre trying to prevent condensation from forming youve got two real choices you can either.
Increase the temperature of that glass or you can decrease the amount of humidity in the air which would reduce. The dew point as long as you can keep the temperature above the dew point youve prevented condensation heres a. Great example of that i remember years ago we had a customer in the midwest who called who had gotten. Windows replaced by us and they called a year two years later saying they were having this huge condensation problem. They thought there was some defect in the windows well we sent a rep out there to take a look.
At it and what they discovered made perfect sense the windows in question were two windows that were right side. By side guest bedroom that this couple rarely used they kept the door to that bedroom closed and they had. The heater vent closed off in that room as well and then in front of the window they had big. Heavy curtains that were like floor to ceiling type covered the whole window so one day after months of not. Using this room they went in there open that window saw this condensation on the window and thought something was.
Wrong really what was going on was because that room was so sealed off from the rest of the house. The air temperature was very low that air temperature was below the dew point or the humidity level in that. Room which is what was causing the condensation to form so as an experiment and we suggested why dont we. Leave the door open to that room for a couple days well leave the curtains cracked open four inches six. Inches something like that and well leave the heater vent open so that warm air is allowed to get into.
This room and well see what happens with the condensation well lo and behold the condensation completely went away so. There was nothing wrong with the windows it was just that the air in that room specifically the air right. Next to those windows had fallen below the dew point which is why the condensation was forming on the glass. In fact the same thing happens at my house we have two big windows that look out the back of. The house and face towards the woods its beautiful its a wonderful view and we have these honeycomb shades over.
Those windows we pretty much never closed those shades except when we go out of town for some reason we. Think its a good idea to close all the shades in the house so well close those shades and then. When we come back from being out of town theres moisture on the bottom of that glass if its cold. Outside whats happening is those honeycomb shades are trapping air between the shades and the windows that air in between. There isnt able to circulate with the rest of the air in the house so it cools off and it.
Cools off and it cools off and now over time it cools below the dew point which is when you. See condensation form so the easy solution is just to leave those blinds up a couple of inches that allows. That air to circulate and then theres no condensation at all very easy solution so if youre seeing condensation on. Your windows the very first and foremost thing i would try is to allow warm air from the rest of. The house or the rest of the room to get near those windows open the blinds a little bit make.
Sure the door to that room is open make sure that air is able to circulate youre probably going to. Solve your problem now if that doesnt solve the problem the next thing to look at is ways to bring. Down the relative humidity level in the room because whats happening is the humidity level is too high for the. Temperature and its causing the condensation so one thing you could do would be to run a human that would. Help to pull some moisture out of the air lower the humidity levels which would then lower the chances of.
Condensation forming on that glass theres other ways to you could look at opening the window let a little fresh. Air in the room once a day or every so often they allow that stale sort of moist air from. Breathing and cooking and showering and everything to escape the house and allow some fresh air in and thatll likely. Solve your problem if you have a bunch of houseplants all over the house that could contribute to the humidity. Level in the air and the condensation as well you might put all the plants or as many as you.
Can kind of in one area one part of the house avoid over watering them so youre not putting more. And more moisture into the air that could do the trick or you can talk to your hvac company about. Fresh air ventilation especially if you have a propane or gas fired furnace that often times can generate a lot. Of moisture put a lot of moisture in the air which will then raise the humidity level which will allow. That dew point to creep up to the temperature level of the air right by that glass again causing condensation.
On the glass as an example we see this in our rv weve got this little rv we go tooling. Around if we go somewhere cold and were running that propane furnace all night in the morning there will be. Condensation all over the place because that furnace puts out all puts a lot of moisture into the air and. Then it condenses all over the the windows one interesting thing to note is that were more likely to get. Calls from people with condensation problems in the south and we are in the north that might not be expected.
Because you might think this is a cold weather thing we have family in alaska you can go up there. And youll never see condensation on the windows in alaska the reason why is the hvac systems and those climates. Are designed for that situation theyre designed to ventilate the house they allow fresh air in they bring that moist. Air out prevents condensation from building up in the house in the south you oftentimes dont see that for example. I recently had a customer in san antonio texas who was furious with his condensation problem he was having with.
His old windows and he was going to get new windows from us to try to prevent this problem in. Talking through with him we did end up getting him new windows and it did help his problem but the. Pictures he sent of the condensation were kind of insane there was moisture everywhere and i told him the windows. Will definitely help what theyll do is raise that air temperature right near the window it will make the new. Windows will be more efficient than the old windows they will reduce the chance of condensate but looking at the.
Amount of condensation he had on his old windows my suggestion was to call his hvac company he needed a. More fresh air ventilation under his gas furnace that would allow more air more fresh air in and take more. Of that humid air out he did both of those things he got new windows and he had an hvac. Company work on the system and his condensation problem was solved there was no more condensation on the windows because. The dew point in the house had fallen and the efficiency of the windows had risen to the point that.
The air temperature was warmer than the dew point no issue at all if this all sounds a little bit. Theoretical lets look at this chart that might help explain what sort of conditions you would want to achieve in. Order to avoid having condensation on your windows as you can see here this handy little chart does put out. By a window manufacturer that my company deals with will show you if its zero degrees outside you would want. To have a relative humidity level inside of 25 percent or less if you had more than 25 percent relative.
Humidity while its a zero degrees outside you do have a chance that condensation will form on that glass now. The more efficient your windows are the higher the humidity level can be in the house but before condensation will. Form and the colder it is outside the lower that humidity level needs to be in order to prevent condensation. Do you see how that works as the temperature goes down the humidity level also needs to go down or. A more efficient window will keep the temperature of that glass higher which would allow you to have a little.
Bit more humidity in the air without causing you a condensation problem so as you see on the same chart. If the outside air temperature were 20 degrees youd be ok with the humidity levels of 35 to 40 percent. Higher humidity levels than that would introduce the possibility of seeing condensation form on the windows and lower humidity levels. Would completely eliminate that problem because theres not enough moisture in the air the dew point would be low enough. Such the temperature wont reach the dew point condensation wont form if you feel like youve done about as much.
As you can to both increase the temperature around the windows and decrease the humidity levels but youre still not. Seeing the results you want theres a couple of other things you can look at one you want to make. Sure that all your proper all your normal sorts of ventilation are working your attic vents are clear and unobstructed. The house is able to breathe as it should you also might want to just open up a window every. Once in a while allow some some of the dry cold outside air to come in and get some of.
That warm moist air out just to help keep the humidity levels where theyre supposed to be its gonna eliminate. Your problem pretty easily in fact in this old house here in new orleans we dont see any condensation on. The windows and these windows are probably 100 years old from the look of them now why dont you see. Condensation well because theyre drafty it is chilly in here even with the furnace cranked up to 72 and thats. Because these old windows just dont seal very well that means theyre letting a lot of of this moist air.
Thats in here out there letting cold dry air in even when theyre shut and thats exactly what people dont. Expect sometimes about buying new windows its not entirely uncommon that somebody gets new windows say they get them over. The summer and then as soon as it gets cold outside they flip the heater on they see condensation on. The windows and they call us up and they say these windows are causing condensation in my house well thats. Absolutely not true windows dont cause condensation what might be happening is that the air your old drafty windows were.
Letting some of that humid air out last winter this wonder of those old drafty windows are gone the new. Windows are sealed up very tight theyre nodding theyre not allowing any of that humidity to get out theyre keeping. That humidity in which is raising the dew point of your air which is whats causing condensation to form as. An example of that many years ago i dealt with a customer south of richmond virginia now she did not. Buy windows from us she about windows from another company in town i happen to know the owner of that.
Company and there are very beautiful outfit but she called up our office thinking she was gonna have to get. New windows all over again actually after she just bought windows last year she was not happy about it and. She wanted us to guarantee that the new windows we would install would not cause condensation in her house well. That can be a tricky thing to guarantee because as weve already discussed theres a lot of environmental factors that. Go into weather in that condensation forms a lot more than just the efficiency level of the window so she.
Was pretty irritated and she was telling us that this other company wasnt able to help her and they were. A bunch of jerks and i know them and i think theyre probably not a bunch of jerks so i. Had a little free time and i offered to just cruise over to her house and take a look at. It so i met her a day or two later and as soon as i walked into the house it. Was pretty obvious what was going on you could see she had electric baseboard heaters around the perimeter of almost.
The entire house there was no forced air there was no vents theres no moving air in this house period. So when the house is all sealed up because it was cold outside the house is all sealed up these. Electric baseboard heaters are running everybody i think there were her and her husband and two or three kids living. There all these people are eating and drinking and breathing all day long and showering and cooking food and and. Putting a lot of moisture in the air well its freezing cold outside so everythings shut and there was a.
Lot of condensation on her windows so shes telling me how you know this is so horrible and i cant. Believe it and look at these look at these garbage windows this other company installed i understand she felt that. Way but thats not really what was going on so i asked her if the old windows before she got. These new windows if the old windows were drafty and of course she said yes right she said oh yeah. They were horrible they were really drafty in fact the new windows dont feel that bad they feel nicer than.
Me then the old windows did but this condensation is driving me crazy i wish i had never bought them. Theyre so bad so i tried to explain to her that thats exactly whats going on the old windows were. Drafty enough that they were letting the house breathe they were letting a lot of this moisture get out the. New windows were sealing tighter they were letting less moisture out which means the humidity level in the house was. Rising to the point where the dew point was was meeting the temperature and condensation was forming so the solution.
For her was just to crack a window once in a while or run a dehumidifier solve your problem she. Can also contact an hvac company they could probably install something a little more permanent for if thats what she. Wanted but without a forced air system that can become a whole rigmarole and im not a hvac expert so. Youll want to talk to somebody else about that but basically what was going on in her house was that. The humidity level was rising and rising and rising imagine if all those people stayed in that house for three.
Or four days without ever going outside well there are all those people taking showers all those people cooking dinner. All those people breathing all day long whats happening the moisture levels going up and up and up and up. To the point where the dew point meets the temperature condensation forms in the window so its not a problem. With the window there was something wrong with the work this other company did it was just an environmental situation. In our house and the really easy solution was just a crack a window so if youre experiencing condensation in.
Your house those are the factors to look at you either need to increase the temperature around the window maybe. Its as simple as just opening the blinds or opening the door to that room or letting the air circulate. A little bit more or do you need to decrease the humidity levels now thats as simple as just opening. A window and letting the house breathe a little bit or maybe running a dehumidifier or even running your bathroom. And longer than you need to to just draw more and more of that moisture out of the house sometimes.
It doesnt take much it might just be a little difference just to get that temperature just a little bit. Above the dew point and you wont have any issue anymore the new windows will hopefully help because they will. Increase the temperature of the air right around that glass because the new windows will be more efficient than the. Old windows as an example lets take a look at a couple of options my company commonly offers now these. Are options we offer in this southern climate zone we would offer different options in different parts of the country.
But just as an example well look at this chart you can see the energy star package and this package. Is the least expensive option wed offer in this area that also meets the energy star criteria for this area. The energy star package here has a condensation resistance rating of 56 now the easiest way to understand whether thats. Good or bad is to look at it in reference to other options so we can look at the next. Option down here which is the same window the same glass the same gas fill the same low e coatings.
The only difference is the spacer that goes around the perimeter of the glass here where were placing a metallic. Spacer with a nonmetallic super spacer they call it and thats the only difference and you see the condensation resistance. Rating goes from 56 to 59 higher is better so that means its more the glass will be warmer and. Less likely to form condensation so thats good you can see down here just to skip ahead we can look. At this triple pane package now a triple pane glass is obviously more efficient than double pane glass so you.
Would expect the condensation resistance rating to rise right that must make sense the air temperature inside the house would. Be a little bit warmer right next to that glass because the glass is more efficient and you see that. In the numbers the condensation resistance rating changes from 59 to 69 quite a big percentage difference thats all very. Intuitive it sort of makes sense and it numbers bear it out so when youre shopping for new windows if. Condensation is an issue for you you want to look for windows with the highest possible condensation resistance rating what.
That means is the glass will stay as warm as it can when the house is all sealed up so. The windows can help but they wont prevent all condensation the house needs to be properly ventilated it needs to. Be allowing outside air to come in and inside air to get out in order to prevent that sort of. Moisture from showing up so if you have a replacement window project in mind i would suggest checking out our. Website at the window dog you will find it is the greatest source of replacement window information on the entire.
Internet if youd like a free and easy and generally completely online quote for your project you can get one. From my company window universe as of today were offering windows in 33 states and the district of columbia and. That list is growing every day you can find links down below in the description to window universe where youll. Be able to get all that information in fact if we dont offer windows in your area we may know. Another great company to recommend so i think youll find that to be pretty helpful you can check out the.
Links down below now we do have some new videos coming up that i think will also be pretty cool. Were gonna do one all about foam in the windows foam around the windows foam inside the windows theres foam. Everywhere when it comes to windows and were gonna help explain what it does and does not do for you. Were also gonna do some new window warranty reviews a lot of really cool stuff coming up so hit the. Old subscribe button down below there somewhere and youll be able to be informed when we have new videos come.
Out in that way you will not miss out so we hope this video helped as youre trying to navigate. Your condensation issue and we will see you guys next time you.
Method 2 – How To Prevent Window Condensation
Hi reuben saltzman with structure tech home inspections here todays topic is controlling condensation on your windows so why am. I bringing up condensation of windows its because its really cold out in minnesota right now like negative thirty cold. Thats on seasonably cold even for minnesota and ive been having a lot of people email me or call me. And say what do i do about condensation if i would notice how do i control this and ill share.
With them a blog post its a guest blog post on my website talking about what to do about controlling. Condensation and i thought i dont just make a video to cover this – so heres the basics of it. The reason you have condensation is because you have moist air coming in contact with a cold surface thats thats. The basics of it we all kind of understand that so the question is how do you control it well. Theres two variables that you can control there you can control the amount of moisture in the air in your.
Home and you can control the surface temperature of the window thats it those are the two things that you. Have control over so lets start out by looking at option number one controlling the amount of moisture in the. Air now ive talked about whole house humidifiers and you know i dont like them by my advice there would. Be if you have a whole house humidifier and its negative 30 outside you need to shut that off when. Its negative 30 your house needs to be uncomfortably dry if you insist on having an moost in your house.
Youre gonna have condensation on your windows thats that i mean theres no getting around it it doesnt mean that. You have bad windows you dont have defective windows you just have windows the next would be to use bathroom. Exhaust fans every time we take a shower turn it on at the beginning of the shower leave it on. Throughout the duration of the shower and leave it on for another half hour to hour after youre done taking. A shower thats seriously how long it takes to get humidity levels back to a normal level humidity back to.
A normal level if youre not comfortable even the fan on and then remembering to shut it back off what. I recommend is putting timers on them you can buy these digital electronic timers at the store you replace your. Traditional switch with the timer you can set it for 30 45 60 minutes ive got everybody in my family. Very well trained you just hit the button and its gonna run for 60 minutes rather than you start taking. A shower so thats good way of doing it side note unless you have a really new home that has.
A neutral wire going to that circuit when youre looking at the story you want to be sure that youre. Buying at a timer that does not require a neutral wire and itll be specifically labeled red on the box. Saying no neutral required or something like that so look for that if youre gonna buy one of those if. You have bathrooms that dont have exhaust fans and its got a shower or a bathtub in there and you. Use it i recommend putting a fan in put in an exhaust fan and of course the fan needs to.
Exhaust to the exterior you cant have it venting in your attic or in the kids playroom if you have. A kitchen exhaust fan use that when youre cooking use it when the oven is on use it when youre. Boiling water use it when youre doing anything that involves cooking if you have too many plants or weeds in. Your home you need to fix that those contribute a lot of moisture to the air if you dry your. Clothes inside by hanging them up you need to fix that too you need to start using your clothes dryer.
And your clothes are better exhaust to the outdoors if it exhaust back there in the inside well thats the. Same as hanging your clothes up inside the house it creates a ridiculous amount of moisture and i dont care. If you put your clothes down in the basement in some far remote room where does that room try to. It dries to the rust of the inside of the house that moisture all makes its way to the inside. Its gonna end up on your windows your windows our dehumidifiers if you have a crawl space with no vapor.
Barrier you need to fix that a lot of moisture is gonna migrate up into the home through the crawl. Space to expose dirt so if youve if youve got dirt somewhere in your basement or at the lowest level. Of your home it needs to be sealed off even if that dirt seems dry its drying because moisture is. Evaporating all the time it needs to be sealed if your home does not have a ventilation strategy no this. Is kind of a complicated one but if you dont have something thats going to change out the air in.
Your home you need to have that added and it goes beyond the scope of this video to discuss all. That but a couple of ways that you could have the arrogating changed out in your home would be want. To be a furnace that has an open flame just like an 80% efficient furnace now thats not intended as. An air exchange system but it is going to end up exchange in the air in your home its going. To pull in outdoor air to support the fuel that its burning and in the end and it does change.
The air out in your home installing an hrv a heat recovery ventilator or an energy recovery ventilator and erv. Either one of those their only job is to exchange air in their home so an air exchanger will do. That if you have one of those fancy bathroom exhaust fans that runs all the time on a low speed. Like so so low that you dont even hear it running maybe 40 cfm something like that and then you. Flip a switch and it kicks into high gear that is a ventilation method for your home its called exhaust.
Only ventilation it always pulls air out and it relies on air leaking back in its not the most energy-efficient. And you cant build a home in minnesota with that type of exhaust with that type of a ventilation system. Anymore today you need balance ventilation but having an exhaust only fan is a whole house ventilation strategy so thats. Thats one way of achieving it and if you want to read more about whole house ventilation strategy and how. To achieve that theres a great blog post by a good blogger a great blogger by the name of alison.
Bales hes got something called the energy vanguard blog check out his blog ill put it on the screen here. Well show the way i could make you a clickable link in youtube i dont know how to .
