"Tim and his team were fantastic. We planned for a significant renovation including several structural elements, carpentry, electrical, and siding and Horsman Builders delivered. Tim was a reliable communicator and addressed our questions in a timely manner. We replaced an entire roof, added walls, doorways, re-did a deck and covered porch, replaced doors, replaced siding, and added new outlets- to name a few. We felt like we could really trust Tim and plan to work with him again in the future."

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"Very well. It is an old house with no straight walls. Craig worked diligently to make sure the bath walls we purchased fit and were plumb. The floor was also a challenge being uneven which Craig did very well addressing it. He used various techniques to level the floor and place the new tile. Very easy to work with and he had good solutions to the problems he faced. He always checked with us to be sure his actions met our expectations."

FAQs for addition to existing structure building service projects in Ossipee, 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.
