"Norman helped us to make our Master Bathroom modern and usable. The process was easy, straightforward and relatively quick! Norman's showroom was a great meeting spot to review and talk about design, choose materials and go over any details. He was communicative and helpful in answering any and all questions throughout the process. We are thrilled with our new Master Bath that feels like we are at a hotel or spa. Thank you Norman and team. Highly recommend Homecraft!"

"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."

"My husband and I are so happy with our new deck. Just in time for the beautiful weather! We have Jose Diaz with Alta renovations corp. to thank for making our home improvement job stress free. He and his crew were extremely prompt, meticulous, courteous and great communicators. Jose made me feel comfortable asking questions and was prompt to respond. It was truly an absolute pleasure working with them from the start to the finish !"

"We hired Coco’s Custom Building on 2 separate occasions. We needed our roof redone and later decided to hire them to replace a dozen windows in our home. The owner Keith provided us with a great quote each time and was able to schedule the work right away. Any questions or concerns I had were addressed immediately which made the renovation go smoothly. I would definitely recommend Coco’s Custom Building and look forward to using them with my future home renovations."

"I cannot speak highly enough of the exceptional craftsmanship and professionalism displayed by Mr. Casteñeda and the employees ofJMC service corps. Their attention to detail and precision in installing the porch railing was truly impressive. Not only did they deliver outstanding results, but they also demonstrated a deep understanding of design aesthetics, seamlessly blending the railing with the overall architecture of the porch. It is evident that they take great pride in their work, and their commitment to excellence is truly commendable. I wholeheartedly recommend their services to anyone seeking top-tier contracting work."

"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!"

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