Can You Replace a Window Without Removing the Siding?

Replacement windows don't need to have vinyl siding taken off.

Replacement windows

are designed to fit into the existing frame of your home, as long as the frame and sill are in good condition. To make sure, measure the window without including the frame and get a replacement window cut with those measurements. To start, remove the nails or screws that hold the window in place and then take out the brackets by tapping them with a hammer.

If you're dealing with an old home, you may need to remove the vinyl or metal siding, but you can install vinyl over wood siding without taking it off. This requires some preparation and may require adjusting window and door frames for a wider wall. Simonton makes it easy to avoid removing or replacing siding since their refurbished windows fit into the existing frame. After that, replace the trim to cover up the foam and sealant that fills in any gaps.

You may also need to take out the drywall around the window inside the house, which will add time to your project since it needs to be put back in place. When you get your new window, make sure it's the right size by measuring from edge to edge of the frame.

Window siding and replacement

is no problem with upgrade windows since they're designed to fit into an existing window opening. Don't forget to add end caps to the window sill and stick them in place for protection from the elements.

It's important to have enough help when replacing a window since they can be heavy and hard to maneuver. Make sure there's no moisture or air circulating around the perimeter after installation. If your window is too big, return it and get one that fits; otherwise you'll need a professional to cut down the opening.
