"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Excellent! Alta Renovations did my bathroom from the studs out. Tile, sheetrock, floor, vanity and the plumbing and towel hardware. The job was was in a co-op, with very frustrating "rules" and "requirements ". Most contractors would not want to participate (paperwork, time schedules and parking restrictions). Jose, the owner of Alta, abided by all the rules, whiles still keeping a smile!!! His workers worked neatly and orderly, knew exactly what had to be done, and did it. Very pleased. I'm recommending him to all my ? ? ? ? ?"

"I used K&A Home Repairs to rebuild my deck. I found them to be dependable, professional and experienced for what I needed. Anthony came at the appointment time to provide a fair estimate and followed the work schedule as close to the plan as He could, weather permitting. I am extremely pleased with my new deck and will be calling K&A for more projects on my home."

"Kenneth from JKL Construction, Inc. did such an amazing job remodeling our kitchen and living room that we hired him again to rip down our old deck and build a brand new one. Once again, he was professional, polite and knowledgeable. He offered ideas how we could put the staircase off to the side and really maximize the space on the deck. His work was beautiful and we couldn?t be happier with the results! We decided to hire him a third time to remodel the front of our house so check out those pictures to see the incredible transformation, as well as the pictures of the gorgeous kitchen he created for us!"

"Hired Elevate Construction for major home renovations and bathroom remodeling. They fixed electrical issues, painted, gutted and restored multiple rooms in my home that were severely damaged. The team was diligent and professional throughout. I was impressed by the quality, flexibility and commitment to finishing the job in the small timeframe I needed it complete. They put extra care into making sure each step of the project met my expectations and had excellent communication. Will hire again for future projects."

"The installers arrived on time, were immaculate and the tile job was perfect. The slab was uneven but they somehow managed to pit in a perfectly level floor. The employees are very pleasant and professional. They came highly recommended by Cancos Tile, which is how I found them."

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