Lets face it, while windows are essential, they're not the most exciting purchase you can make for your home. Consider the fact that windows can also be pretty expensive and they become even less exciting! The good news, is that you don't have to over spend to replace the windows in your home. We would love to help you find the style and the quality that you need, but at a price you can afford!

Builders Surplus offers windows for every home and every budget with three categories of windows: In Stock, Special Buy, and Special Order. No matter the shape, size, color or style that you are looking for, we can deliver - for the best value possible!

We offer top brands including MI Windows that are made in the USA, and Andersen Windows that have been a favorite of homeowners for decades. Whether you need just one window or a enough to do your whole house, and whether you choose DIY installation or our installation team, Builders Surplus is the place to go!

By signing up for a complimentary window consultation, you'll be working with one of our Window Experts that will visit your home to measure, identify any potential installation problems, and help you find the right windows for your home and your budget.

What Our Customers Have to Say:

"Builders Surplus Saved Me $12,000 on My Windows!"

“I had gotten two quotes from some of the well known window companies. They had quoted me $18,000 for windows and installation for my whole house. I'm so glad I check with Builders Surplus first, because they were able to get me everything I needed for only $6,000!

"I was able to save so much money on the surplus windows!"

“I needed 6 windows and was calling around for quotes. A friend of mine mentioned Builders Surplus so I went out and took a look at what they had in store. I was so lucky to find all 6 windows that I needed in their surplus selection and saved a TON of money! Install was great too!
