What we do
Two things, done properly
Window Inserts replaces windows and doors — not roofs, not siding, not kitchens. Thirty years of narrowing it down to what we're good at.
Windows
Replacement and custom windows in every operating style — double-hung, casement, awning, sliding, bay and bow, picture, specialty shapes.
- Andersen · Marvin · Harvey
- Insulated low-E glass
- Matched to the windows you keep
Doors
Entry, patio, French, sliding, storm and interior doors — fitted to the opening so they close, latch and seal the way a door should.
- Andersen · Therma-Tru · Marvin · Harvey
- Weather-tight sills & multi-point locks
- Fit is the whole job
Also: custom windows for non-standard openings, and energy-efficient glass packages on every project.
Before you call anyone
Is it time to replace, or just repair?
Not every drafty window needs replacing. Check the signs that sound like your house — the result will tell you whether this is a part swap or a project, and there's no email wall.

What the work looks like
Real replacements by our crew across Westchester, Putnam and Fairfield County.
How it goes
From the first call to the walkthrough
No surprises. Here's every step of a Window Inserts project, and roughly how long it takes.
Free in-home estimate
We come to the house, look at every window or door you are considering, and tell you plainly which need replacing and which can wait. You leave with honest pricing.
Field measurement & product selection
Once you approve the estimate, we take exact measurements of each opening and help you settle the manufacturer, style, color, glass and hardware.
Your order is placed
We order to your measurements and spec, and keep that spec on file so anything added in a later phase matches. Custom items have a longer lead time; we tell you the window up front.
Installation day
The crew protects floors and furnishings, removes the old units, sets and insulates the new ones, and checks operation and locking on every one. Most homes are done in a day or two.
Walkthrough & cleanup
We open, close and lock every window and door with you, clean up, and take the old units and debris with us. Your installation carries a one-year labor warranty.
