Frequently Asked Questions
How much should I expect to pay for replacement windows?
Replacement windows cost $400-$1,400 per window installed. Vinyl double-hung windows run $400-$700 each. Wood and fiberglass windows cost $700-$1,200. Bay and bow windows range from $1,500-$4,000. Full-home replacement averages $8,000-$20,000.
Is it worth it to replace old windows?
New windows reduce energy bills 10-25% and improve comfort. They are worth it if current windows are drafty, hard to operate, single-pane, or 20+ years old. Energy savings alone rarely justify the cost—consider comfort and aesthetics too.
How long do replacement windows last?
Vinyl windows last 20-40 years. Wood windows last 30-50+ years with maintenance. Fiberglass windows last 40-50 years. The glass seal (preventing fogging) typically lasts 15-25 years and can often be replaced separately.
What time of year is best to replace windows?
Spring and fall offer ideal weather: moderate temperatures minimize energy loss during installation. Summer works but can be hot for installers. Winter is possible with proper tarping but uncomfortable. Most contractors have shorter waits in late winter.
Are vinyl or fiberglass windows better?
Fiberglass is stronger, more energy-efficient, and lasts longer but costs 30-50% more. Vinyl offers excellent value for most homes. Choose fiberglass for extreme climates, larger windows, or if you want to paint to match your home.
