Why is a window installation just as important as the window itself?
A Window Only Works Right when it's Installed Right.
Windows only give you the energy savings you want if they're installed correctly.
Improperly installed windows let in air, water, moisture, and vapor that can cause mold, rot, and send your potential savings literally out the window.
Be sure that your installation is going to be done properly, so you will realize the savings you should get with your window upgrade. You may want to ask your contractor the following:
How long is the warranty on the caulk or sealant?
Will you include an adhesive flexible flashing of opening sill pan (pre-formed or flexible)?
Will you include a head flashing or drip cap?
Will you include a backer rod behind joints?
What is the level of experience and expertise of the installers that will be working on my home?
