How To Replace Storm Window Glass In A Metal Frame
Posted on: 25 August 2016
If you have broken storm window glass, you commonly only need to replace the glass. A replacement glass pane will increase the energy efficiency of your home as well as prevent rattling that is common in older panes. A begining DIY person can easily replace this glass. Here are tips to replace storm window glass in a metal frame.
Prepare to Work
For this project, you need:
- work gloves
- safety glasses
- tape measure
- paper bag
- damp rag
- broom or vacuum
- masking tape
- Phillips screwdriver
- putty knife
- caulk and caulk gun
- sandpaper
- drill with screw attachment for rusted screws (optional)
- replacement glass,
Vacuum or sweep as many broken pieces as you can, and dispose of them in a paper bag. Pull broken glass from the frame with pliers. If the glass is only cracked, make an "X" with masking tape over the glass to keep it from shattering when you remove it.
Measure the length in three places from the exterior excluding the frame: the center, left, and right. Measure the width at the bottom, top, and center. Note the lowest measurements of the height and length to order glass. You may prefer to take a picture of the window to help the sales person find the right match for the style of window.
Remove the Old Glass
Use the putty knife to pull the vinyl spline (sealant that holds the glass to the frame) free. If it has caulking instead of a spline, scrape the caulk off with the knife.
Get a helper to stand outside to help support the glass, if needed. Loosen the screws with the screwdriver and detach the frame screws. If the screws have stripped, use a drill with a screw bit attachment designed to remove rusted screws. Remove the frame pieces, and set them and the screws aside. Buy new screws.
Carefully remove the glass and wipe the inside of the frame with a damp rag. Sand the grooves of the frame, wiping dust with a damp rag.
Install the New Glass
Reattach the frame, and tighten the screws. Place the glass in the frame and leave a small gap on all sides to allow for expansion.
Reinstall the spline. If there is no spline, apply a thin layer of caulk around the edges. Do not caulk weep holes (gaps) on the bottom, so moisture can escape.
Your storm window will look like new. If you don't trust your skill, or the window is seriously damaged, contact a window replacement service.
