Replacing your old windows can be a tedious DIY project especially if you have never replaced a window before. I’ve include a DIY video in this post that shows step by step how to install a replacement window in your home.
Installing new windows is a great way to improve the look of your home and also lower your heating bill in the process, if you life in a cold climate. Another point to ponder is that in order to improve you homes energy consumption you need to install energy efficient replacement windows.
How to Install Replacement Windows
Here are some steps that should be good general guidelines for installing windows yourself. Some replacements will have nailing flanges especially if they are new. If your installing used replacement windows they may have the nailing flages cut off. This is usually not a problem. You will need to nail or screw through the jamb, much like installing a door.
Step 1 – Double check your measurements to make sure the window you intend to replace is the same size.
Step 2 – Caulk the inside edge of the outside window stops, and along the windowsill. Just a thin bead of caulking will do.
Step 3 – Place the window in the rough opening after you have caulked the nailing flange. If there is no nailing flange simpley set the window in place. I’ve found it works good to set it on shims so there is an equal gap around the entire window.
Step 4 – You should save the trim from the old windows. You will need to refinish by installing the inside stops and trim.
Step 5 – Caulk where the trim meets the window fram both inside and out.
Step 6 – Go outside and examine your handiwork. The window should have a sloped frame that matches the slope of the sill. If not, it should come with an insert that can be used to cover the gap. If there’s a gap but you don’t have an insert, you can cover it with a piece of wood. Caulk the seams where the insert (or your piece of wood) goes against the frame.
Step 7 – Good Job!
