Call today for a quote! As an owner operator I am personally involved with every project. John

"John was great initially - getting there and tackling the immediate problem and answering my calls. We had a short in the electrical heating fan/motor in the floor that was potentially dangerous and could have caused a fire so he replaced the breaker and rewired the fan/motor. However, when he left we noticed that the fan was not running in the box and he told us to detach the wires which I felt was risky and also meant the problem was not fixed. He said he would come back the following Monday to inspect the rest of the wires underneath the house and he never did. He was also supposed to send me a photo of the burned wires, a work order/receipt for my files, and never did. I texted him about Monday and about replacing the fan/motor - either to let us what it was called and we would replace it ourselves or give us the cost of replacing one or all 3 boxes. He never responded so we still have a heating system that is not fixed and perhaps dangerous if only running on two fan motors ."

Hampton Design and Build is pleased to be partnering with HomeAdvisor to offer our full service addition, design and remodeling services to the greater East End area. We have been in business for over 30 years and we pride ourselves in our exemplary service, our craftsmanship and attention to detail. Being a full service contracting company there is no need to go anywhere else. Please call for a free estimate.

"We have done projects with different contractors, but putting an addition on to our house was by far the biggest project we had ever done. We were terrified of its breadth and complexityâ particularly as concerned making the house comfortable for my elderly parents and more accessible for my son, who uses a wheelchair. We met with several contractors and chose HDB both because their bid was more reasonable and because we had a gut feeling of trust that, fortunately for us, never ebbed throughout the process. Choosing HDB was the best decision we have ever made in the 10 years we have owned our house, and we will continue to solicit their expertise for any future work. At every step of the process they demonstrated their authenticity, integrity, empathy and expertise. For questions we had about anything, big or small, we received a response within a day. We added two and half rooms and bathrooms to ones side of the house. Based on his vast experience in our area, Dale had important, smart suggestions for modest but powerful improvements elsewhere in the house that would not have occurred to me but proved to be invaluable--and increased the value of our home dramatically. He navigated town permit issues. Cost was very reasonable and if there were any questions, he was open to discussing and adjusting. Diane had superb design instincts, which saved us from hiring another professional, and as part of the fee she sent wise suggestions for vanities, light fixtures, paint colors, rugs and more; and then ordered the items directly. Both obviously cared about us and the project and made everything as easy as possible for us. Most projects we had done previously had faltered at the end, with smaller punch list items; but as usual, Diane and Dale were responsive til the final t was crossed and I dotted. HDB is a rare company with skill and expertise but also with a passion for their work and a spirit of kindness and concern for their clients that made a house addition â something we dreaded--actually fun. Thanks HDB!"

FAQs for addition to existing structure building service projects in Calverton, NY

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.
