"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."

"HomeAdvisor put me in touch with Gary of CGP Construction. I had purchased a prefabricated swim/spa unit and I was looking for someone to do the site preparation work required to install the spa in ground. Gary made a site visit and shortly thereafter he provided a very detailed and competitive estimate for the project. He and his crew evacuated an area in the yard, poured a concrete slab, and build a cement block retaining wall which will house the spa. He also dug the trenches and installed PVC conduit for the water and electrical connections. The site prep work was completed. Everything looks great and the work was recently approved by the local building inspector. The spa/pool is schedule to be installed next week and I look forward to Gary and crew returning and completing the finished masonry and stone work around the unit."

"Jeff and his crew were amazing! If I could give them 10 stars I would. We needed a bathroom ceiling repair and an exhaust fan installed. Jeff suggested crown molding for around the entire bathroom and it came out gorgeous. Not only are they great at what they do but theyâ re professional, honest and so neat with their work. I was fearing a dusty mess and there was none. If youâ re looking for someone to do anything and everything, this is the company to hire!"

"I can’t thank iRiverdale Construction enough! From start to finish, Raquel Diamond and her team exceeded every expectation and truly made my family’s dream home a reality. Raquel managed every aspect of the project from A to Z. She handled all of the permits, worked directly with the town to get every approval, and took the stress completely off our shoulders. Throughout the entire process, she listened carefully to every idea we had and helped bring our vision to life. From the structural work to every finishing detail, her professionalism, knowledge, creativity, and dedication were evident every step of the way. She was always available to answer questions, offer guidance, and make sure everything was completed with the highest level of quality and craftsmanship. What started as a dream became a beautiful reality because of Raquel and iRiverdale Construction. Our home is everything we imagined and more, and our family couldn’t"

"We hired Fine Finnish for my home renovation project, and we couldn't be more pleased with the results. From start to finish, the entire process was smooth and professional. The team was incredibly skilled, paying great attention to detail and ensuring that every aspect of the project was completed to the highest standard. The team also made sure to clean up after themselves each day. Communication was a strong point throughout the project. Vincent (contractor/owner) kept us informed at every stage, providing clear timelines and updates,which made us feel confident and involved. The project was completed on time. Overall, we highly recommend Fine Finish for any building or renovation needs. Their professionalism,expertise and dedication to customer satisfaction are truly commendable. We look forward to working with them again in the future."

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