Frequently Asked Questions
Is it worth replacing all windows at once?
Yes — replacing all windows at once typically saves 10–15% vs. individual replacements, as contractors can price the job as a package. You'll also get consistent style and avoid mismatched energy ratings.
How much can I save on energy bills with new windows?
Energy-efficient windows (double-pane Low-E) can reduce heating/cooling costs by 12–24%. In cold climates, the savings are higher. Payback period is typically 10–15 years based on energy savings alone.
What's the difference between vinyl and fiberglass windows?
Vinyl is the most popular choice — affordable ($300–700/window), low-maintenance, 20–30 year lifespan. Fiberglass costs 20–30% more but lasts 30–40+ years and resists warping in extreme temperatures.
How long does window replacement take?
A professional crew can replace 8–10 windows in a single day. The full home window replacement project typically takes 1–2 days depending on the number and complexity of windows.
Do I need a permit to replace windows?
Like-for-like window replacement (same size opening) usually doesn't require a permit. Enlarging the opening or adding new windows requires a permit in most jurisdictions.
