Many replacement windows today are constructed of vinyl, which makes them light and easy to work with. But they can also create some continuity challenges when you're putting them in homes made of wood or brick, where they can sometimes look out of the place. You won't have that problem with vinyl replacement windows in mobile homes since the homes are generally made mostly of vinyl and other manufactured materials. The process for window installation in a mobile home is the same as in other types of homes, though the smaller dimensions can make the project somewhat easier.
Things You'll Need
- Tape measure
- Pry bar
- Vinyl replacement windows
- Plastic shims
- Screw gun
- Long mounting screws
- Spray foam insulation
- Finish nailer
Measure the opening of the mobile home window, along the height and width, with the existing window still in place. Order the replacement window unit with those measurements. Leave the existing window in place until the new ones arrive.
Remove the existing windows, prying off the perimeter of trim from around the inner edge of the opening. This will allow the windows to be pulled out of the opening and into the room. (Note: Keep the trim intact as you remove it, and set it aside.)
Set the new window unit in the opening, first setting the bottom on the sill and then pushing the top in and back until it rests against the outer perimeter of trim.
Hold a level on the unit and push plastic shims around the edges of it until it is level throughout.
Shoot mounting screws through the sides of the window unit, outward, into the surrounding frame to hold it in place.
Fill the gaps around the edges of the window unit with spray foam insulation.
Nail back in the trim that you removed earlier, using a finish nailer. Caulk around the edges of the trim.
