"I had an old refrigerator, microwave and some other things to be removed from my backyard. Robert was the original guy I I contacted. We talked pricing and then arranged a Time for pickup. Vinny was the worker that came out on time I may add he introduced himself and got straight to work it took him about not even 15 minutes to get all the stuff on the trailer. We talked for a bit and he informed me that they were a construction company that also did repairs and to keep them in mind if I ever needed anything which I will I've added them to my contact list. I think Robert and Vinny are phenomenal guys. They were both professional and friendly at the same time. I gave them five stars but that really not enough to describe how they made me feel like a special and valued customer. So this is my personal rating; 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟Satisfaction! 🤗🤗🤗🤗🤗 Friendliness! 👍🏼👍🏻👍👍🏾👍🏽👍🏿 Getting the job done! "

"This is the second time we have used Rowland and the team at Dwell Renovations. We built a full addition for my mother in law. Kitchen, living room, bath, bedroom. We couldn’t be happier with how it came out and my MIL is unbelievably pleased. Rowland and all of the contractors, electricians, plumbers and tile folks treated the job like they were working on their own homes. They were patient with our hundreds of questions and requests. Rowland kept us in the loop every step of the way and met , or beat, every timeline. He always had great advice and a keen eye for the details."

"Matt and his team did a phenomenal job. Going into the project, my biggest concern about hiring a contractor was reliability—I had heard too many stories about contractors not showing up or following through. Matt completely put those fears to rest. He was always available to discuss any concerns and personally visited the job site to make sure everything met my expectations. His top priority was ensuring I was happy with the work. Even months after the project was completed, when a small issue came up, Matt followed through and made sure it was corrected. I had completely gutted my kitchen, and I couldn’t be happier with the results."

"After a student driver accidentally crashed into our home, damaging the foundation and front porch, we were overwhelmed and unsure where to begin. A trusted friend recommended A. Hubert Construction, and from the very first conversation with Arthur Hubert, I knew we were in capable hands. Arthur handled every step of the process personally. He was consistently communicative, clear, and reassuring... something that meant more than I expected while dealing with unexpected home damage. He didn’t just repair the house, he approached it thoughtfully. He treated our 120-year-old farmhouse like a piece of history worth honoring. He works with multiple masons, but instead of sending whoever was available, he handpicked a specialist experienced in older homes to ensure the original brick foundation was restored correctly. That decision alone told me everything about his standards. During the work, Arthur also spotted an unrelated structural issue, a joist in the basement that had never been"

FAQs for addition to existing structure building service projects in Trenton, NJ

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.
