Buyer's Guide
What to Look for in a Window Company
Verify Licensing & Insurance
Always confirm the company is licensed in your state and carries both general liability and workers' compensation insurance. Ask for certificates before work begins.
Get at Least 3 Quotes
Pricing varies significantly between companies. Getting multiple quotes is the single most effective way to avoid overpaying and to identify outliers — both high and low.
Understand the Warranty
A strong warranty covers both the product (glass seal, frame, hardware) and the installation (labor). Get all warranty terms in writing before signing anything.
Ask About Installation Crews
Some companies use in-house crews; others subcontract. In-house crews tend to be better trained on the specific products they install. Ask who will actually be doing the work.
Check for ENERGY STAR Certification
ENERGY STAR certified windows meet strict energy efficiency guidelines set by the EPA. They can reduce heating and cooling costs by 12–15% annually.
Read Recent Reviews
Look for reviews from the past 12 months on Google, BBB, and Houzz. Pay attention to how the company responds to negative reviews — it tells you a lot about their customer service.

FAQ
Common Questions
Start with licensing and insurance — any company you hire should be licensed in your state and carry general liability and workers' compensation insurance. Beyond that, look for a company that offers a warranty on both the product and the installation, has verifiable customer reviews, and provides a written quote before any work begins. Getting multiple quotes (at least three) is the best way to ensure you're getting fair pricing.
The national average for window replacement ranges from $300 to $1,200 per window, including labor. A full-home replacement of 8–10 windows typically costs between $3,000 and $10,000. Premium brands like Renewal by Andersen or Marvin can run higher. The best way to get an accurate price for your home is to get free quotes from local contractors.
Not necessarily. National brands offer consistency, strong warranties, and established reputations. But many local window contractors offer comparable quality at lower prices, with more personalized service. The key is to verify licensing, check reviews, and compare warranties regardless of whether you go national or local.
Most professional crews can replace 8–10 windows in a single day. Custom-ordered windows typically have a lead time of 2–6 weeks before installation begins. The installation itself is usually completed in one day.
A solid warranty should cover both the product (glass, frame, hardware) and the installation (labor). Look for a lifetime limited warranty on the glass unit — this covers seal failure and fogging between panes. Installation warranties vary widely; some companies offer lifetime coverage, others offer 1–5 years. Always get the warranty terms in writing before signing.
