"Fine Design did a great job on our bathroom from the gutting to the finish. Dave and Lenny were easy to work with and the workers were great! Cleaned everything up each day and were very polite. The quality of the work is outstanding. Everyone was very professional and was a much more pleasant experience compared to other contractors I have used. Thanks again-I highly recommend Fine Design."

"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."

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