WHat Homeowners Say About Their Aptitude Basement Remodel
We recently had Aptitude Design and Build remodel the lower level of our home—adding two bedrooms, a full bathroom, a family room and a wet bar—and we couldn’t be happier with the results. Their communication, attention to detail, professionalism and genuine care for our project stood out every step of the way. Greg and James were awesome—their creativity and problem-solving made all the difference in turning our ideas into a beautiful, functional space. We would recommend them to anyone looking for a trustworthy, talented and friendly design-build team.

We recently completed a basement remodel with Aptitude and the entire experience was outstanding from start to finish. Owner Matt came out personally for the initial project scoping and he was professional, thorough and easy to work with. Our project manager, James, kept communication clear and consistent throughout—always responsive and on top of every detail. Jared, our lead contractor, did excellent work and made sure everything was completed with care and high quality. The whole team was great to work with and we’re extremely happy with the final result. We would absolutely choose Aptitude again for future projects!

We couldn't be any happier with our new basement thanks to Matt and his team at Aptitude! The entire process was top-notch - from the initial design through the final touch-ups. I would highly recommend Aptitude to anyone considering a home construction/renovation/expansion project.

Ok. Let's get real here. Aptitude Design & Build did an amazing job with our basement. Matt and his crew were incredibly professional and their work was equally amazing. Matt listened and knew exactly what I wanted. All of the staff were respectful and professional. Not one person has come to my house and not commented on the quality work that Aptitude has done. Would definitely recommend!!!

We are very pleased with the results of our remodel. The project included three bathrooms, home office, bar area, tv/golf putting green area and miscellaneous trim and flooring upgrades. As an architect and two people who work from home, we had very specific things we wanted to improve in our home and it was all executed as anticipated in and around our busy schedules.

We wanted to add main floor laundry to our house and decided to do so by adding a wet bar with a small laundry closet to our living room. Aptitude's work exceeded my expectations. They did a beautiful job creating my unique vision of a custom wet bar and laundry closet. The craftsmanship is excellent and they fully executed my vision. Its a beautiful space and a joy to do laundry in.

We had a lot of items to update in our house and from the very first meeting with Aptitude, we were impressed. The communication was always there, the crew were all on time, great attention to detail, cleaning up the job site at the end of the day. The most important aspect to me is the communication to know they are aware of what's going on and actively creating a plan to keep the job moving and that's exactly what they did. We will absolutely use them again in the future as well as refer to anyone looking for work.
