Key takeaways
- Insert keeps the frame and trim and is faster
- Full-frame fixes rot and changes sizes
- Inspect the frame before you decide
Insert replacement
An insert, or pocket, replacement fits a new window inside the existing frame. It is quick, keeps your trim and siding and costs less. It requires a frame that is sound, square and dry.
Because the new frame sits inside the old, there is a small loss of glass area.
Full-frame replacement
Full-frame replacement removes the window, frame and often trim, so the opening can be inspected and repaired, flashed and insulated properly. It is the right choice for rot, leaks or a change in size.
It takes longer and costs more, but fixes more.
How to choose
Probe the sill with a screwdriver and look for stains. If the wood is soft or there are leaks, choose full-frame. If everything is solid and you want a quicker job, an insert may be perfect.
A professional inspection settles it, and we offer one.
