"I had the pleasure of working with Dave for my kitchen renovation. From start to finish, their attention to detail and craftsmanship were truly remarkable. The contractor displayed excellent communication skills, always keeping me informed about the progress and any changes that needed to be made. Not only did they complete the project on time, but they also exceeded my expectations in terms of quality. Every aspect of the kitchen, from the countertops to the cabinetry, was flawlessly executed. Additionally, Dave was highly professional and respectful throughout the entire process. They were always punctual and ensured that the work area was clean and organized at the end of each day. It was a pleasure having them in my home."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

"cannot recommend this company enough. They very graciously took on my very difficult project after another contractor resigned. I am beyond happy with the result. I know that with this company that the job has been done properly. Robert was able to communicate exactly what was being done, when, and why. The communication was unmatched. I will actually miss their excellent communication, the job was done in a timely manner. More was completed with this company in 2 weeks than 10 months with my previous contractor. Robert was kind and hardworking. I have only positive things to say about Classic Home Design and Construction LLC and I will happily use them again in the future, and I am thankful I was put in touch with such an upstanding company and people behind it."

"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!"

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