TLDR: Incredible work, detail oriented, flexible and high quality performance.
I had a contractor do a shoddy job on a porch remodel and needed someone to come in, be smart and creative and not break the bank. The team did an excellent job with high attention to detail fixing my porch. I will be a repeat customer. Glad I found someone so reliable.

After months of researching various contractors, I ultimately chose Alpha Design and Builds LLC to refinish our basement. From my very first interaction with Kevin, he assured me that he would turn our unfinished space into something specialand he delivered on that promise. Kevins communication was outstanding, keeping us updated every step of the way. He was professional, attentive, and genuinely cared about making us happy.Once we signed the contract, Kevin set a clear start date and his team showed up exactly on timejust as promised. On the first day, they protected our wood floors with care, covering the entryway, laundry room, and all pathways leading to the basement. Every member of Kevins crew was professional and courteous, greeting us with a friendly hello and letting us know their schedule each day. Many times, they stayed late to keep the project on track.Kevins estimate was very fair, and as someone who loves interior design, I had plenty of ideas as the project progressed. No matter what I requested, Kevin always responded positively and found a way to make it happeneven the things that seemed impossible. The finished basement far exceeded our expectations. From the tile work (our family now calls the craftsman the tile man because he was so skilled!) to the sheetrock, painting, countertops, and flooring, every detail was handled perfectly.I rarely give perfect reviews, but if I could give Kevin and Alpha Design and Builds 10 stars, I would. My husband and I are thrilled with the results and are already planning our next project with them. Kevin is a true professional and someone I will recommend without hesitation. Finding quality workmanship and such a positive attitude is rare these days. Thank you, Kevin and team, for everything youve donewe look forward to working with you again soon!Below are Before and After Photos! Enjoy

I recently hired Alpha Design Builder to completely remodel my basement, and I couldnt be happier with the results. They built a full gym room, added a new bathroom, and installed a beautiful bar kitchen area.The entire team was very professional, punctual, and easy to work with throughout the whole project. They always showed up on time, kept everything organized, and completed the work within the agreed timeline. The quality of the work exceeded my expectations, and the final result looks amazing.Im very happy with their service and would definitely recommend Alpha Design Builder to anyone looking for reliable and professional remodeling work.
