"When you find a great contractor, don’t let them go. ;). I hired Tim to build a screen porch under my deck but added several projects as I recognized the high quality of work and attention to detail from his crew. In addition to the screen porch, they built a deck extension - so nice that I decided to have them replace the existing deck, installed a basement slider and replaced the door, installed a new fence and built a shed. Tim was responsive, open, honest and receptive of my requests and additions during the project. Great experience working with Tim and his crew: Dan, Brian, Eddie and Ben. Great job on all the work - I’ve received many compliments from neighbors and guests on the work you did! I can’t recommend Tim and his crew enough."

"Asa again was easy to work with. He is professional and honest in his recommendations and was fine if I wanted to go in different direction as long as it maintained the quality of the work. I almost always went with his recommendations though. Other tradesmen have commented on the high quality of his work which meant that potential renters were willing to pay more to live in such a great place!"

"It went great. Chris built our custom home exactly to our specifications. We lived out of state for the entire build. Chris maintained open lines of communication with us so that we always knew what was going on. His work is impeccable. His attention to detail resulted in our dream home being exactly what we expected when we hired him. His group of subcontractors were great throughout the entire process. I have not spoken to anyone in the area that has anything but praise for Chris and his work ethic. Chris came highly recommended by a number of people and I would carry on that tradition and recommend Chris Johnson for any construction project from a remodel to building a new home from the ground up. I would certainly use Chris again for any future construction needs."

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

"My wife and I chose BG Construction to stain the exterior of our cabin and also the interior of our covered deck, to include railings and all landscaping ties. We knew there would be extensive scraping and caulking and we also feared there would be unforeseen problems that would require carpentry and other construction. WE received a complete walk around and possible problems were pointed out to us. An accurate estimate was given, barring of course, unforeseen work. Bill Gray and his associates, Bobbie and Frank, were nothing short of fantastic! They are courteous, extremely friendly, and about the hardest workers we have seen in a long time. They became part of our family during their time here. If you are looking for a full service outfit that are capable of not only painting but fixing things too, you can't do better. Bill and his crew are craftsmen. Choosing BG Construction was one of the best investments we have made concerning our home. Eric/Patt"

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