"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."

We pride ourselves on being a unique construction company. Everything Under the Roof is an interior, residential construction company owned by Kim and Jay Spanier. At work we are a husband and wife team, but at home we are mom and dad, so we truly understand the importance of keeping your project orderly and on time, while keeping your family (including your pets) safe. We can also guarantee NO high pressure sales calls, and no crabby, condescending construction guys working on your home improvement project – just our family helping yours! Kim is your main point of contact through the project. She walks you through the construction process, acts as your personal construction jargon translator, and, most importantly, she is the budget master. Kim will help you shop for materials so that you stay on budget. Jay is the jobsite superintendent. He manages the day to day activities of your remodeling/construction project, he coordinates and manages the sub-contractors, and it’s his skillful carpentry that will transform your home. All of our projects work within the existing footprint of your house. What exactly does that mean? Well, in a nut shell, we don’t do additions, and we won’t raise your roof. We find all the hidden, un-used spaces in your house and re-create your floor plan to work for you and your family.

"Kim and Jay created a beautiful master bath for us. The combination of Kim’s selections and Jay’s workmanship was a perfect fit. They listened to our needs and fulfilled all of our expectations."
