Insert vs. full-frame window replacement
There are two ways to replace a window, and the choice changes both the price and what problems get fixed. An insert replacement reuses the existing frame; a full-frame replacement takes the opening down to the studs. Here's how to tell which one your house needs.
Key takeaways
- Insert (pocket) replacement reuses a sound existing frame, faster and cheaper.
- Full-frame replacement removes everything down to the studs and costs about 25% more.
- Choose full-frame when there's rot, water damage, or the opening is out of square.
- Insert is fine when the existing frame is solid and you just want better glass.
- A good installer inspects the frame before recommending one over the other.
Insert (pocket) replacement
An insert replacement sets a new window into the existing, sound frame. Your exterior trim and interior casing stay put, so it's faster, less invasive, and less expensive. The trade-off: you keep the old frame, so it only makes sense when that frame is solid and square.
Full-frame replacement
Full-frame replacement removes the old window down to the rough opening, frame, trim, and all, so the installer can inspect for rot, re-flash, and correct an out-of-square opening. It costs roughly 25% more and takes longer, but it's the only way to fix hidden water damage and reset the weather seal.
Which one do you need?
- Pick insert when: the existing frame is sound, you're mainly after better glass and lower bills, and the opening is square.
- Pick full-frame when: you see rot or water stains, the window has been leaking, or the opening has shifted out of square.
- Get it inspected: a trustworthy installer checks the frame and tells you honestly which install the house needs, rather than defaulting to the cheaper or pricier one.
