Nick was a pleasure to work with, and I highly recommend him. He was responsive to my request to replace a second-story deck and was communicative throughout the process. He performed most of the work himself, only subbing out the painting. I couldn't be happier with his work!

When at the end of a big construction project do you actually still love your contractor? I do!! Bertram builders is incredible. A local guy that has built a team from guys he grew up with, so they are all incredible. He shows up when he says he will and takes care of what he says he will. Thank you Nick, I truly love my house now.

I can’t thank Nick and his team enough for their hard work. Nick is extremely easy to talk to and friendly he knew exactly what I want done and he got straight to work. Thanks again and I’ll be calling him again for my next project.
