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!
