"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"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."

"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 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.
