Replacement Windows

What we do

Replacement Windows

Old windows leak heat, fog up and stick. We install energy-efficient replacement windows that are measured, fit and sealed to your openings — so your home stays warmer in winter, cooler in summer and quieter year round.

01

Energy-Efficient Units

Double- and triple-pane insulated glass with low-E coatings, rated for New England winters.

02

Custom Measured

Every opening measured on site so units fit square and true, with no gaps to chase later.

03

Flashing & Sealing

Proper flashing, house wrap integration and sealing keep water out and conditioned air in.

04

Trim & Finish

Interior and exterior trim finished cleanly so the new window looks original to the house.

Frequently asked questions

Questions, answered

How do I know it's time to replace my windows?

Drafts, condensation between the panes, sashes that stick or won't stay up, and rising heating bills are the usual signs. If the frame is rotting or the glass seal has failed, replacement is almost always cheaper long-term than repair.

Will new windows lower my heating bill?

Yes. Replacing single-pane or failed double-pane windows with modern low-E insulated units cuts a meaningful amount of heat loss, especially combined with proper sealing around the opening.

How long does a window replacement take?

Most homes are done in one to two days depending on the number of openings. We work opening by opening so your home is never left exposed.
