Weep Holes in a replacement window
When you buy new windows you look at the overall window design and beauty. Very often you do not look at the small details of the replacement window. One of the smallest parts of the window are weep holes. Let us see why are they important.
Window weep holes are located on the exterior of the replacement window in the bottom of the window sill as you can see in the pictures.
The most important job weep holes do is draining all the water that gets into the frame of the window. When it is heavy rain, some of the water gets trapped in the bottom of the window and then it comes out from these weep holes.
Problems with window weep holes
When you buy your windows, make sure that weep holes are one inch higher from the lowest point of the window. This way you can be sure that they are not gonna be accidentally caulked or clogged with dust. If the weep holes get clogged with dirt or spider web, then the water is not properly drained from the window. After some time water is gonna start leaking into the house and destroy two by fours and eventually cause mould build up in the house.
Weep holes maintenance
So you bought vinyl maintenance free windows, but here we go I have just used this nasty word Maintenance. Yep, if your Windows have weep holes, you will have to clean them from time to time. If you have in your house twenty windows, it doesn't mean that you will have to clean weep holes in each one window. Clean the weep holes that you can visually see are dirty. May be on the side of the house where you have a lot of trees and spider nets.
How to clean weep holes
Take some piece of wire and gently insert into the weep hole and move back and forth till you pull out dirt or spider web. Then pour water on to the sill of the window and see if it is flowing out from the weep holes.
How to eliminate completely weep holes problems
When you don't want to do any kind of maintenance, then when buying your new replacement windows make sure that a window does not have weep holes. Yep all the windows we sell are without weep holes. It means the whole frame is fusion welded and the bottom sill is sloped. So all the water does not get inside the frame of the window, but diverted away from the house.
