Common Questions

Window FAQs.

How do I know if I need new windows or just a repair?

Drafts, fogging between panes, difficulty opening or closing, and visible rot in the frame are all signs it may be time to replace rather than repair. We'll give you an honest recommendation during your free estimate.

Do new windows really lower energy bills?

Properly installed, well-sealed windows reduce drafts and heat loss, which can help lower heating and cooling costs — though actual savings vary by home.

Can you also repair the trim around my windows?

Yes — window trim and frame repair is part of our carpentry work, and we're happy to handle it alongside a window installation or repair.
