"Lonny and his team did a fabulous job on building our deck! Their work is meticulous! Every time I look at the deck - I love it! Lonny was so easy to work with- he worked with me on last minute design changes without any complaints. He just wanted me to be happy. I would rate Lonny a 10 plus! Definitely recommend him"

"I hired Solimine to build an addition sun-room and attached deck from a hand sketch of what I envisioned. They were able to create just about exactly what I was envisioning from the sketch. Work was very professional and all the crew were responsive to questions and comments as they arose. They were also willing to work with me on cost and payments allowing me to upgrade from the original sketch. I would definitely hire them again."

"This company is fabulous. Renald and his workers gave a great estimate, and did the job flawlessly designing and executing the building of my exquisite patio. He met us at the supply house to help us pick out materials, he took a personal interest. Beside our beautiful patio, I had him redo our fireplace which looks like a work of art! And since the chimney needed some attention, they fixed some problems with the chimney. All work was beautifully done. I recommended this company to friends of mine, and they hired Renald and his crew and got back to me as to how terrific they found his work and the ease it was to work with them. This is how things should be....attention to detail, quality craftsmanship! I'm happy I could submit this review!"

"Timber and Meghan were great to work with. The price for the work was extremely reasonable and Timber was very flexible and creative with solutions. The original plan was to power wash and treat the existing fence and pergola. Timber suggested going over the old fence with a new fence and building a new pergola.The overall cost for these changes was pretty much the materials. We provided Timber with a photo of a pergola that we found on line and he recreated it flawlessly. I cannot praise Timber highly enough. We are thrilled with the new deck. One of our friends is a retired home builder who is never impressed. He had nothing but praise for the quality and craftsmanship of the work. We already have plans to engage Timber for additional projects. PS We had to order a new dishwasher while Timber was here. He installed it for us and took the old one away."

FAQs for addition to existing structure building service projects in Sandy Hook, CT

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.
