Winter has arrived and it’s important that you maintain and prepare your patio doors for the cold months. Even the best patio doors need maintenance, especially when you’re preparing for weather extremes. We recommend checking the following as soon as you can:
Condensation and Humidity
Condensation does not immediately indicate bad patio doors. If you notice condensation forming on the interior surface, it means your patio door seals are working perfectly, though you might need to look at your indoor humidity. On the other hand, condensation between the glass panels is an entirely different thing. It means the seals around the glass panels have failed and allowed moisture through. Repair depends on what kind of windows you have. In the worst case, you might need to replace the window sashes.
Another consequence of failed seals is that if you have the airspace filled with an insulating gas, it may already have leaked out. These gases are non-toxic, but the immediate problem is that when it leaks, it doesn’t allow air to fill the vacated space, creating a vacuum that pulls the glass panels closer together. There will be noticeable warping on large glass patio doors, which may require professional repairs before the glass permanently bends or cracks.
Renewal by Andersen® patio doors do not have this problem, thanks to strict quality checks at our manufacturing facilities. We also use components tested to withstand weather extremes.
Locks and Hardware
If you have sliding glass doors, open them all the way, clean the tracks and close them gently. If you have French doors, open them all the way, note any creaking, then inspect the door hinges for signs of rust. Apply the prescribed lubricant as needed then close them. The sashes should perfectly align. If not, there could be a hardware issue, which you will either need to replace or repair. You should also be able to lock the doors without much effort.
Check around the door edges. If you feel drafts, the weatherstripping may not be forming a proper seal. Avoid leaks not only because they’re uncomfortable but because they lead to heat loss, which increases heating costs. Fortunately, weatherstripping is replaceable, but certain adhesives do not work well in cold or moist environments.
