Frequently Asked Questions
What signs tell me I need new windows?
Common signs you may need new windows include drafts, condensation between panes, rising energy bills, difficulty opening or closing windows, and noticeable wear or damage. If your home feels less comfortable or you’re constantly adjusting the thermostat, it may be time for a professional window assessment.
How long does installation usually take?
Most window installations take about 30–60 minutes per window. For an average-sized home, the full project can often be completed in 1–2 days. Our team provides a clear timeline during your consultation and works efficiently while respecting your home and schedule.
Are your windows energy efficient?
Yes. We install high-performance, ENERGY STAR® rated windows designed to reduce heat loss, block UV rays, and lower your energy bills. Our expert team ensures proper installation, which is key to maximizing energy efficiency.
