Trusted By Homeowners. Proven By Results.
We used James Allen Builders to build our first house almost 20 years ago. I found them to be extremely easy to work with, very timely and communicative. I have used them repeatedly for smaller projects throughout the years and have never been disappointed in the quality of their workmanship and their overall professionalism.

We hired them for a complete exterior renovation, and the difference is night and day.
The quality of the installation is top-notch, and the house looks brand new. If you are looking for a contractor to handle a major exterior overhaul, I highly recommend them.
THE NORMAN FAMILY

We just had our roof replaced by James Allen Builders. We were very impressed and appreciated how careful the crew was, and how they protected and covered all the areas while working. This was a positive experience from start to finish, and we would highly recommend them!
