Frequently Asked Questions
How long does window installation take?
Most standard window installations take 1–2 hours per window. A full home typically takes one to two days, depending on the number of windows and installation conditions.
What types of windows do you install?
We install single-hung, double-hung, casement, sliding, picture, awning, bow and bay, garden, transom, geometric and impact windows.
How energy efficient are new windows?
Modern replacement windows can significantly reduce heat transfer, helping lower energy bills while improving indoor comfort year-round.
Will new windows reduce outside noise?
Yes. Upgraded glass packages and tighter seals can dramatically reduce outside noise, especially from traffic, neighbors, or weather.
Do your windows come with a warranty?
For over 20 years, we have been committed to providing our customers with durable, high-quality products. All windows and patio doors we sell come with a manufacturer’s lifetime limited warranty, good for as long as you own your home!*
