"If you want sloppy incomplete and incorrect work hire Hilltop. Bill did not use the products contracted for- used less expensive options without telling us - and hardly ever showed up. The job went way beyond promised finish date. Paid the full balance, Bill then left the work unfinished and ghosted us!"

"We hired Tomasetti Builders & Remodelers at the end of 2020 to renovate our kitchen. The project involved completely gutting the old kitchen and opening up the walls to make it an open space to our dining room and living room. In addition, we added a slider to the dining room area. The project was scheduled to begin November 2nd and began as planned. The owner Larry and his wife Joyce were very nice to work with when preparing the contract and initiating the project. Prior to meeting Larry and Joyce, my husband and I had a design of the new kitchen already, but Joyce took us to the stores they engaged with on a regular basis to select kitchen items such as the backsplash, floor tiles, and kitchen faucet. Joe was the project foreman and the one we consistently worked with on a daily basis. Joe came with his co-worker Mike to perform the work. They were extremely professional to work with and Joe was an excellent communicator. Joe provided daily summary updates on the days they worked on the project in addition to next steps. When I reached out to Joe, his response was prompt in providing answers to my questions. Joe ensured the contractors were kept informed of the situation and adjusted their scheduling as needed based on project progression. Both Mike and Joe worked hard every day they were present and Joe ensured the job progressed so that it was complete as close to the agreed upon timeline, as possible. Joe ensured the job met our expectations. Our satisfaction was his ultimate goal. Mike and Joe are the reason our kitchen renovation was done exactly how we wanted. We are ecstatic with the renovation results and would recommend hiring Tomasetti Builders with Joe and Mike working on the job."

"Zach at Reichelt construction built a garage for us. We are incredibly pleased with the final product. He was communicative, asked for our input, and was professional throughout the process. He even helped us out afterward when we needed to get an electric vehicle charge installed quickly. It was not inexpensive by any means, but it was definitely a reasonable price given the quality of the work and materials. It took a few months beyond the six months stated in the contract, but we have come to expect this with projects such as this one, and we never pushed to have it done faster. We could not recommend Reichelt CC enough if you have a job you want done right."
