I should have used you

"I reached out for a quote with your company awhile back and I had a great experience and regret not going with your company. The price was a bit higher than the company I selected but it has been a painful process so far. Neighbors who have seen the construction have asked me for a referral and I’ve provided your company instead of the one I’m currently using."

Far exceeded our expectations

"I cannot say enough good thing about Design Builders.  We live in a small house in Old town Alexandria.  They were able to make our vision for having a sunroom a reality.  They worked with our architectural board, stayed in constant contact, offered weekly meetings and updates.  We love our room and would recommend Design Builders to anyone. "

So many ideas and options

“I didn’t know exactly what I wanted. I had some ideas in my head, but I looked at lots of examples online to see the kinds of things you built. That gave me a lot of good ideas. Everything was accounted for in the checklist. Even things I never thought of. I loved that. I could go through and pick out every single thing I wanted.”
