"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.

"Everyone at Allen Building Specialties is exceptional and a pleasure to work with."
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

"The best part for me - when he laid out the timeline he hit the mark."
Trae and his company did an outstanding job for us. He helped us with a commercial buildout of our coffee shop. Trae provided constant contact, mixed with ways to save on our overall buildout as we went along. The best part for me - when he laid out the timeline he hit the mark. No 2, 3, 4 weeks delay/time or cost overruns like you hear from time to time with other contractors.

"The finished product was exactly as we had pictured and the final cost was exactly as contracted!"
Trae and his company of professionals were a true delight! The remodel was as painless as possible for us, considering that we needed to be living in the house while the work was being done. The finished product was exactly as we had pictured and the final cost was exactly as contracted! Any remodel has unexpected issues, but all of these were dealt with promptly and professionally. Thanks to all of you at Allen Building Specilaties.

"Trey was honest and up-front"
Would I recommend Allen Building Specialties? Absolutely! Not just for basement remodeling, but anything that required remodeling, additions, or renovations. I am glad I picked them to do the work and I would use them again.
"They did excellent work and completed it on schedule"
Trae and his team remodeled our kitchen. They did excellent work and completed it on schedule. Everyone he brought into our house was trustworthy, patient, competent, and easy to get along with. They kept the site very clean and structured their work so that we would be without a functioning kitchen for as little time as possible. They stayed completely within the bid except for a few extras we decided to add. Trae was here every day to check on progress and quality. He had some great ideas that looked great in the finished kitchen. We would highly recommend Trae and his crew!
"Our daughter absolutely loves it!!"
We received a recommendation from our realtor to use Allen Building Specialists for a small remodeling job for our home. Everyone involved with this company was very professional, timely, and did a wonderful job. The job involved confirming that a wall between 2 bedrooms was not load-bearing, the wall then removed, followed by patching the walls and ceiling between the rooms. Our daughter absolutely loves it!!

"Any future projects we need, Allen Building Specialties will be the first and ONLY phone call we make."
Trae and his workers were great to work with. Trae is knowledgeable about the business and provided us options with our Master Bathroom Remodel. The foreman of our project, Mike, was incredible. His tile work was outstanding and meticulous. We could not be more pleased with the finished project. Any future projects we need, Allen Building Specialties will be the first and ONLY phone call we make.
Donna Z.
" I highly recommend Allen Building and would definitely use Allen Building Specialties again!"
We updated a house we had lived in for 27 years. We built a new fireplace at end, added hardwood floors, updated kitchen cabinets, updated ceiling, and lighting. Trae was wonderful. He was very professional, always returned my calls promptly, helped me to stay in my budget, was very patient as I made decisions and his skill and workmanship were beautiful. I did not have a decorator help, and I would show him pictures of what I wanted, and he always understood. He is honest and I trusted him completely. I highly recommend Allen Building and would definitely use Allen Building Specialties again!
Jan D.
"We were thrilled with the finished product!"
Trae, and his crew, removed a wall in our home, and built a new stone fireplace, creating a truly "open concept" between our kitchen and Great Room. Trae shared his knowledge and many good ideas....He and the crew were always professional and very courteous in our home. The project was done within the predicted scope of time and cost. We were thrilled with the finished product!
