Customer Testimonials

FAQ

Questions, answered with clarity.

How do I know if my windows need to be replaced?

Signs include drafts, condensation between panes, rising energy bills, or difficulty opening and closing windows.

How long does window installation take?

Most projects take 1–3 days, depending on the number of windows and the type of installation.

What types of windows do you install?

We offer double-pane, triple-pane, vinyl, and custom window styles like bay, bow, casement, and picture windows.

 Will new windows really lower my energy bills?

Yes. Energy-efficient windows reduce heat loss in winter, minimize heat gain in summer, and can significantly cut energy costs.

Can individual windows be repaired instead of replaced?

Yes. If damage is limited to a seal, pane, or hardware, we can often repair instead of replace the entire unit.

Do you offer custom sizes and designs?

Yes. We provide custom window sizes, grid patterns, finishes, and styles to perfectly match your home’s design.
