How it works

Four steps. No pressure at any of them.

  1. Call, text or send a request

    Tell us what's bugging you: drafts, foggy glass, windows that stick.

  2. We measure at your house

    Free. We look at every opening and walk you through your options.

  3. You get a clear price

    Before any work begins. Then take your time deciding.

  4. Install day

    Most homes take one to two days. We protect your floors and clean up before we leave.

What customers say

"Then the ball was in my court."

From our Google reviews, word for word.

★★★★★
…Shane was professional, straightforward, and to the point. He came out, measured the windows on our house, didn’t put us through a long sales presentation, and simply gave us a quote. Even better, his price came in far below the other quotes we had received. …

I had to replace all the windows in my house and had a great experience with Shane and Green Country Windows. He was easy to communicate with, responsive and flexible, and never played any sales games. His prices were great and install was finished in one day. I still have a sliding door that will eventually need replacement. I'll definitely be returning to Green Country Windows when that time comes!

So happy we went with Green Country Windows. Shane and his crew were great to work with from start to finish. There was absolutely no pushy sales pitch or hidden fees, just honest pricing and solid communication. The guys who did the installation were quick, super respectful of our space, and cleaned up everything before they left. The new windows look awesome and you can instantly feel the difference in the house. Definitely give them a call if you need windows done!

Loved working with this team from start to finish! From choosing my windows to finished installation, this process couldn’t have been easier. Both Shane and the installation team were awesome and extremely professional. I would absolutely recommend their window service to all my friends and family.

I was skeptical to even talk to someone because you get so pressured by salesmen but that wasn’t the case with Shane at Green Country, he answered my questions, gave me pricing and then the ball was in my court. The process was great and did I mention the windows are wonderful!

★★★★★
Employee was very up front and honest when meeting for estimate. I felt no heavy pressure to purchase. However, their estimate was very competitive and I found the quality of window was great. Highly recommend!

Why we started

"After working for larger home improvement companies, we saw how inflated prices, lengthy sales presentations and poor communication could make a straightforward project frustrating. Our approach is simple: explain your options, provide an honest quote and do the work with care."

Common questions

Straight answers before you decide.

Do you offer free estimates?

Yes. We come out, look at your current windows, talk through what you want, measure, and give you a clear price. No obligation and no pressure.

How long does installation take?

Most homes take one to two days, depending on how many windows and how tricky the openings are. You get a timeline with your quote.

Can windows be replaced in winter?

Yes. We replace one opening at a time to keep the cold out, and we check the weather and the product limits before an install day.

Do you offer financing?

Yes, through Wisetack, for eligible customers. You can prequalify on our financing page.

Do your windows come with a warranty?

Yes, our limited lifetime warranty, for as long as you own your home. It covers our installation, the window’s parts, the glass seal and glass breakage, with a few exceptions.
