Do all the windows need to be done at once?

No. Many households phase replacement by elevation or by the worst performing rooms. Ask whether pricing per window changes with the size of the order so you can plan phases realistically.

Can windows be replaced in winter?

Yes. Crews work opening by opening so the house is never fully open, though very cold or wet conditions can affect sealants and scheduling. Ask the installer how they handle weather on the day.

Window replacement

Insert versus full frame replacement, how long installation takes, and what a complete quote should specify.

Two installers leveling a new replacement window in a rough opening

An insert replacement keeps the existing frame and is faster and less disruptive. A full frame replacement removes everything down to the rough opening and is the right call when the frame or sill is damaged. Installation is usually measured in windows per day rather than days per window, and the quote should name frame material, glass package, disposal and trim work.

Key points

Rot at the sill rules out an insert replacement.
Compare glass packages and frame material before comparing prices.
Interior and exterior trim restoration is a real line item, not a detail.

Insert or full frame

If the existing frame is square, sound and dry, an insert unit fits inside it and preserves the exterior trim. If there is rot, water damage or an out of square opening, a full frame replacement is the only way to fix the underlying problem rather than cover it.

What a complete quote specifies

Frame material and the specific product line
Glass package, coatings and gas fill
Whether disposal of the old units is included
Interior and exterior trim, capping and finish work
Product warranty and separate labor warranty

On the day

Clear furniture and window treatments from the work area
Plan for dust control and open access from inside and outside
Expect the crew to work opening by opening rather than all at once
Walk each window before the crew leaves and test operation and locks
