"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"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!"

"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."

"Before hiring Vinnie (Fine Finish) we met other clients in the neighborhood who were using him and they gave him stellar reviews. We met with multiple contractors and not only did Vinnie give us the best price for the services we needed I hired Vinnie to start a project that included redoing 3 bathrooms, complete basement renovation, all windows and siding and they started in April of 2022. Throughout the project we had various changes and additions and he was very accommodating even day of changes and the additional services that we requested were priced reasonably. If I had to remodel the house again or another house Vinnie would be my first call. Thank you so much Vinnie and the Fine Finish team for a job well done."

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