Why Install New Windows?
Lower Energy Bills
Old, drafty windows can account for 25-30% of heating and cooling costs. Energy-efficient replacement windows can reduce your utility bills by up to $500 per year.
Increase Home Value
Window replacement offers an average ROI of 70-80%. New windows dramatically improve curb appeal and are a major selling point for potential buyers.
Improved Comfort
Eliminate cold drafts, reduce outside noise, and maintain consistent temperatures throughout your home. UV-blocking glass protects furniture from fading.
Low Maintenance
Modern vinyl and fiberglass windows never need painting, resist moisture damage, and are easy to clean. Many feature tilt-in sashes for convenient cleaning.

Frequently Asked Questions
How long does window installation take?
Most standard window replacements take 30-60 minutes per window. A typical whole-house window replacement (10-15 windows) can be completed in 1-2 days.
What's the difference between insert and full-frame replacement?
Insert replacement (retrofit) installs new windows into existing frames - faster and less expensive. Full-frame replacement removes everything including the frame - necessary if frames are damaged or you want to change window size.
How much can I save on energy bills with new windows?
Energy-efficient replacement windows can reduce heating and cooling costs by 15-30%, saving the average homeowner $200-$500 per year. Actual savings depend on your current windows, home size, and local climate.
What warranty do you offer?
Most quality windows come with a lifetime manufacturer warranty on the frame and sash, plus 10-20 years on glass seal failure. We also provide a lifetime workmanship warranty on our installation.
Can you install windows in winter?
Yes! We install windows year-round. Modern installation techniques minimize exposure time (typically 15-30 minutes per window), and we take extra precautions to protect your home from the elements.
