"My wife and I are very pleased with the work done by Matteo, Jose, Vicente and Juan. Matteo presented us with reasonable estimates for the two jobs we wanted done. One bathroom was gutted and renovated. It looks absolutely wonderful now. My wife and I provided the materials, but Matt was helpful in making suggestions. Jose added a control panel that now allows us to control water flow to the other bathroom and kitchen without having to turn off the water for the building. The master bedroom/studio was painted and looks great.. Among other things, they fixed a slanted doorway and replaced a door. We'd highly recommend them."

"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."

"I first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"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!"

"After several estimates and meeting with multiple contractors, we decided to move forward with this team and we do not regret it! They were thorough with the estimate, helpful with financing, and offered their recommendations on styles but weren't pushy. This experience was entirely catered to us and we genuinely felt taken care of. The project itself took longer than we expected, but the team did find some structural damage that needed fixing and, of course, any renovation typically takes longer than estimated due to unforeseen circumstances. The guys working on the house were respectful, clean and friendly, and were even great with our two dogs so that I never had to worry about anything. I felt totally comfortable with them being in our home every day. Roberto and Steven were incredible, and if you have a chance to request them, do it! They helped me understand every single thing they were working on and kept in constant communication. Not to mention, the work is clean and super well done! At the end of our project there was a mishap where someone forgot to put an appliance hose back in the drain pipe which caused our basement to get some water, but the guys came right back to the house and cleaned/fixed everything as if it had never happened. All in all, we would definitely use this team again and we are so grateful to have our dream kitchen."

"Great! It turned out beautifully. I wouldn't have anyone else do my construction work. They are simply the best! It's really nice to see the owner of the company working side by side with his crews. He cares and he is honest and provides the highest quality of work. And they won't try to charge you for stuff you don't actually need. I already plan to hire him again in the future. I would highly recommend this company to ANYONE!"

"We hired Coco’s Custom Building on 2 separate occasions. We needed our roof redone and later decided to hire them to replace a dozen windows in our home. The owner Keith provided us with a great quote each time and was able to schedule the work right away. Any questions or concerns I had were addressed immediately which made the renovation go smoothly. I would definitely recommend Coco’s Custom Building and look forward to using them with my future home renovations."

"Memo was great. They finished the job faster than expected while still maintaining high quality work. They were able to create an additional bedroom from largely wasted space. They were clean in their work leaving no mess behind. I’m very happy with the work and will use the company for future projects."

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