Customers say: Quality work

"This is the 2nd job we has Steve do for us. The was a min bathroom renovation and also kitchen backsplash. Bathroom came out great. He walled off a second door to access the bathroom, ripped out old tile, and put down new tile and installed a new vanity. Very happy with the finished product. Steve also did the backsplash in the kitchen. It came out perfect. I would definitely recommend Steve for any home improvement projects you may have."

"Great! Richard had a cancellation and asked if he could come in that time slot. We were delighted. He was prompt. Richard is knowledgeable, explained everything he was going to do, was very professional and friendly. He worked both inside and outside. The job looks very solid. Our realtor came over a few days later ( we are selling our house in the spring) and was very impressed with the workmanship. I would highly recommend Jackson Foundation Repair."

FAQs for addition to existing structure building service projects in Hillsborough, NH

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
