Once an agreement has been processed for a window replacement project, a more in-depth and accurate measurement of every window that is being replaced will be scheduled. This will ensure the best fit before manufacturing begins. This step is often referred to as the critical measure and usually takes up to a couple of hours. Once the windows have been manufactured and delivered, the window installers will carefully remove the old windows and dispose of them. The new windows will be properly fit into the existing opening, ensuring the windows are level, square, and plumb. Windows will then be fastened into place by screwing the window into the blocking. Once the window is securely in place, then the window installer will properly seal the window and finish trimming out the exterior opening. This type of installation will ensure the window does not sag, settle, or become unlevel, which affects the operation of the window.
Some companies will take a shortcut, installing windows outside a manufacturer's specifications. You should only trust your new window replacement to a licensed, bonded, and insured contractor that has been properly trained to meet or exceed AAMA recommended installation guidelines, like Valentine Roofing.
