How to Choose a Window Replacement Company: Questions to Ask Before You Sign

The best way to choose a window replacement company is to compare written quotes line by line and ask the same questions of every company. Did they assess each frame or quote new windows by default? What exact product and glass are they quoting? Is each opening an insert or a full-frame installation? Who does the installation, how is each opening sealed, and what are the scope and warranty terms in writing? A company that answers clearly, on paper, is usually the one to trust with your home.

Eight Questions to Ask Before You Sign

1. Did you look at each frame, or are you quoting new windows for every opening? Some openings may only need new glass, and some need full-frame work. A quote that treats every window the same may not reflect what your house needs. Our glass vs. full window guide explains the difference.
2. What exact window are you quoting? Ask for the manufacturer, product line, frame material and the glass package, including the Low-E coating. "Energy-efficient vinyl window" is not a specification.
3. Is each opening insert or full-frame? The methods disturb your trim and walls differently and are priced differently. See full-frame vs. insert replacement.
4. Who will install the windows, and who is my contact on the day? Know who will be in your home and who to call with questions.
5. How will each opening be insulated, sealed and flashed? Water management around the window matters as much as the window itself.
6. What happens if you find rot or damage once the old window is out? Ask how it is handled and how changes to the scope are approved before work continues.
7. What does cleanup include? Confirm that removal and disposal of the old windows is part of the quote.
8. What are the warranty terms, in writing? Ask what the manufacturer covers, what the installer covers, and get both on paper, not as a verbal promise.

How to Compare Quotes Fairly

Put the quotes side by side and compare the same things in each.

If you live in a neighborhood with an HOA, also check whether the quoted color, grid pattern and style match what the HOA allows before you sign.

Red Flags to Watch For

• "Sign today" pricing. A price that is only good if you sign before the salesperson leaves is a pressure tactic, not a discount.
• No product details. A quote without a manufacturer, product line and glass package cannot be compared.
• Every window gets the same answer. If no one looked closely at your frames, the quote may include work you do not need.
• Verbal promises. Anything about scope, schedule or coverage that matters should be in writing.

Choose the company that assesses your windows honestly, names exactly what it is installing, and puts the scope and terms in writing.
