A recent Google review describes a large addition and renovation by Seth and his team that included a three-car garage addition, a four-season room, a pantry, an office, roof, masonry work and painting, with finish work on exposed beams and trim. That customer wrote that there were a few unexpected challenges and that Seth stood behind his work and made sure the issues were addressed. Another recent customer described a 1,000 sq ft project where an issue with the soil many feet below the surface, found about $40k in, brought a steep increase in cost.

Other recent jobs include a deck off a bedroom, a bedroom and deck addition, and soffit fascia replacement that one customer said was done quickly and efficiently. In an earlier 2026 review, a customer wrote that Seth and his team renovated their entire home, including a new kitchen, an added bathroom, two renovated bathrooms, a four-season room addition, a deck, new flooring, and wet and dry bars, and that he kept them on budget. In a 2025 review, a customer described a sinking three-season room that needed bracing, lifting and a window replacement, and wrote that the budget came in as quoted. In another 2025 review, a customer wrote that the company did a railing and stairs for their porch. In a 2024 BuildZoom review, a customer wrote that Seth built their home and told them up front what the costs were.
We had an addition completed on our home this past April, and we couldn’t be happier with how everything turned out. From start to finish, the team was great to work with—professional, reliable, and easy to communicate with throughout the entire project. The addition came out beautifully and has given our family so much more space to spread out and enjoy our home. It has made such a difference for us, and we absolutely love how everything turned out. They paid attention to the details and made sure we were happy with the finished result. Months later, we’re still so glad we chose them and would absolutely recommend them to anyone considering an addition or home renovation.
We recently completed a major addition and renovation project with Seth and his team, and overall we couldn’t be happier with the outcome. This was a large project that included a three-car garage addition, four-season room, pantry, office, roof, masonry work, painting, and a number of other custom finishes. Throughout the project, Seth was responsive, easy to work with, and his crew consistently took pride in their craftsmanship. The finish work on the exposed beams, trim, and overall attention to detail came out beautifully. Like any large construction project, there were a few unexpected challenges along the way. What mattered to us was that Seth stood behind his work and made sure the issues were addressed. He stayed engaged until everything was completed. If you’re looking for a contractor who cares about the quality of the finished product and takes pride in his work, I wouldn’t hesitate to recommend Seth and his team. We’re very happy with the final result and would absolutely use them again.
What an awesome job S&A Innovations did on our deck off our bedroom. If you’re looking for someone to do work for you these are the guys to call. Finally someone who takes pride in their work. Very very professional workers. If I could give them 10 stars I would. Thanks Seth.
After meeting with multiple contractors, my wife and I agreed that the energy and commitment we felt from Seth and his team was the best fit for us. We all knew this was a sizable project (1,000sq feet) and a large undertaking for all involved, but never could have foreseen the issue that existed with the actual soil many feet below the surface. Already $40k into the project we had little choice but to consider our options on how to proceed at what was now going to be an tremendous increase in cost. It was, but I compliment Seth on his handling of the situation, given that it was unchartered territory for him, having to approach a customer with no favorable options, and only steep, unforeseen increases. No fault of his own, Seth presented the facts as well as his candid opinion. Frustratingly, we proceeded with one of our options. He was receptive to all of our needs and accommodations throughout the project and most importantly, made every effort to ensure utmost respect was paid to my wife during the project, and the cleanliness of the home. We have 3 small children, and this was a 2 year project, and Seth and his team were ever present the whole way. We are thrilled with the work they did. Our only regret was not having them do the flooring too! We strongly recommend Seth and his team to anyone looking to renovate or build. He is incredibly committed to his work and to pleasing his customers, and people like him only get better by doing more work. Both a great worker and a good man Seth is. Onward and upward for S&A Innovations
Seth Davis and the crew at S & A Innovations replaced some soffit facia on our home.The work was done quickly and efficiently and the finished product looks great! Both Seth and Johnny were highly professional and we would hire them again and will happily recommend them for your construction or renovation needs.
