"We are THRILLED with our remodel and we actually ENJOYED the process!"
What sets Trae Allen apart from other contractors is 1) his adherence to the schedule and 2) his excellent communication system. Regarding communication, everyone involved in the project is on an email software system so there is total accountability and written proof of all orders and changes. We are THRILLED with our remodel and we actually ENJOYED the process! Not something you hear very often after a construction project!

"They were so professional and easy to have in the house "
Trae and his team did an outstanding job on our upstairs remodel. They were so professional and easy to have in the house that unlike during past experiences with other contractors, we didn’t feel “invaded”. The project was also completed on time. Our upstairs is now so beautiful that it’s an absolute pleasure to hang out up there with our kiddos. We’re looking forward to working with Trae again, when we tackle our master suite remodel.

Trae and his team are friendly, trustworthy, and knowledgeable. They refinished our basement and their work is excellent; we are thrilled with the outcome. Having a contractor to work with all of the third parties involved was necessary and Trae ensured that everything was completed at the utmost level of quality. They completed the job within the timeline agreed to. I highly recommend them.

We have now used Allen Building Specialties for 4 projects and we couldn't be more pleased. After working with a couple other contractors and finding them very undependable and with poor workmanship, we finally found Allen Building Specialties. We have worked with Mike the most. Mike is the definition of going above and beyond what is required and expected. Everyone at Allen Building Specialties is exceptional and a pleasure to work with
