We had 14 windows replaced in one day. The crew was incredibly efficient, the interior trim was left cleaner than when they started, and the difference in noise and temperature has been night and day. Wish we'd done it sooner.

Common Questions

Frequently Asked Questions

For a typical insert replacement, an experienced installer can complete 8–12 windows per day. A full-house replacement on an average New England home is usually a one or two-day job.

Yes — especially if your current windows are single-pane or have failing seals. Double and triple-pane windows with Low-E coatings significantly reduce heat loss in winter and heat gain in summer.

Insert replacement drops a new window into your existing frame — less disruption, lower cost, ideal if the frame is still solid. Full-frame replacement removes everything and starts fresh — necessary when there's rot, water damage, or major sizing changes.

Energy Star certified windows may qualify for federal tax credits under the Inflation Reduction Act. Some utility companies also offer rebates. We can point you toward the right resources when we do your estimate.

Yes. We reinstall or replace interior casing and apply a clean paint-ready finish. For full-frame replacements, we also handle exterior trim, caulking, and flashing so the window is fully weather-sealed inside and out.
