Replacement windows are readily available at your local home supply store in the Delaware Valley area. They offer great value as an upgrade that will improve your home’s appearance. They’ll also eliminate drafts which affect your heating and cooling efficiency. If you’re wondering how to install replacement windows, the steps are not complicated. As long as water has not damaged your existing window frames, new windows will mount securely in the openings. Here, the window replacement experts at PJ Fitzpatrick explain how the process works.
Steps to Install Replacement Windows
- Cut through paint or varnish along edges of interior sash stops with a utility knife.
- Gently pry off stops because you’ll want to put these back on after the new window is in place.
- Remove bottom window sash first. Cut cords attached to weights as you go. You can let the weights drop unseen inside the window frame.
- Pry off the parting stops on both sides to access and remove the top sash.
- With screwdriver or pry bar take out the pulley hardware.
- Fill exposed spaces in the frame with insulating spray foam.
- Put down beads of acrylic sealant along edges of sill and across its length.
- Position new window in the space.
- Insert shims along edges behind holes where the screws will go into the frame.
- Use the carpenter’s square to confirm that the window is squarely in place. Adjust shims as necessary to achieve this.
- Attach window to frame with screws.
- Apply caulk around the exterior edges of the window.
- Cut off exposed ends of shims on the inside.
- Apply more caulk at interior edges.
- Put the interior sash stops back on.
