If you want new windows in your home, you need to work with an experienced installer who can carry out the installation to the highest standards and who will avoid these five common installation mistakes.
- The rough opening is incorrectly sized. Rough opening requirements for replacement windows depend on the manufacturer and style of the window. While a window can be built to fit almost any opening size, many manufacturers opt to build standard sizes that cost less than custom-made windows.
- There is no back slope. On a rough opening, the sill should be sloped so it can send rainwater or snowmelt that has entered the home back to the outdoors. A skilled installer understands the importance of this feature and won’t forget to add to the height of the rough opening to properly accommodate the thickness of a sloped pan.
- The flashing is poorly adhered. Trusted window replacement companies will brush away dust and wipe off moisture from window sills to improve the adherence of flashing membranes. They will also make sure to follow the cold-weather guidelines of the manufacturer if needed. An amateur installer, however, might recklessly skip these steps and use a product that doesn’t comply with the manufacturer’s specifications.
- The nailing fins are not sealed. Fins that are not fundamental to the window unit should be sealed to the frame. To do this, a good installer will carefully roll the flashing tape over the fin and extend it onto the edge of the frame.
- The spray foam is misused. Dispensing too much foam increases the risk of distorting the window frame. Another mistake that some installers make is filling the cavity around the window with expanding spray foam. This technique usually prevents uninvited water from escaping back to the outdoors.
