"Greg & his team did a wonderful job on my renovation project, with exceptional marks for honesty and communication. Pricing was fair, and there was always confidence in the work itself: it's clear that Greg brought a tremendous amount of experience to the project, and he consistently ensured that work was done correctly (down to every last detail). I could not ask for a more reliable and honest person to deal with! Additionally, the scope of work changed on our project due to additional requests we had (our decision to re-do walls, install new lights, etc.) yet there was never any worry or concern on unfair pricing. Greg gets five-stars, and we will definitely work together again in the future."

"Anthony Scardino, the owner of TAS contracting and his crew did an amazing job. He was always reachable and easy to talk to and work with. They were reliable, neat and clean. Though my job was a small one, I would mosts definitely hire him for any future work needed in my home and I would highly recommend him to anyone looking for a great contractor!"

"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."

"CNM did a fabulous job. We had had a flood in our bathroom and the entire room had to be replaced. We were out of town and we hired Matt and Jose from CNM on the recommendation of a friend. We did not meet them in person until the end of the job. We communicated via text,email and phone. Our building is 100 years old so major upgrading was required and it had to be updated to match NYC building codes. CNM helped navigate us through getting the required permits. When we finally met Jose and Matt at the end of the job we could not be more delighted. The bathroom was beautiful and exactly what we wanted. Thank you Jose and Matt"

"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!"

"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."

Customers say: True professional

"We live in a prewar coop building in Manhattan and were in need of a kitchen, living and dining room/den renovation. Because of the limitations in our building, we were not optimistic that many changes could be made that would dramatically alter the feel/function of the space. Inson Wood proved us completely wrong. With his architectural eye and his impeccable design aesthetic we (and everyone who has been here before and after) experiences our apartment as an entirely different living space. Even family members are shocked at the transformation. I think that what Inson accomplished was the product of a few significant factors. First, Inson asks you what you want and seriously considers how you live. If Inson thinks that different approaches should be considered for what you want, he provides renderings of each option so that you can easily visualize and imagine them. Ultimately, Inson respects your preferences and works with them, elevating them to a level far above what you had imagined. Inson uses the highest quality vendors (whom we NEVER would have found) and expertly guides you through choices (note: follow his recommendations!!!)- our walls would never have had dimension and our kitchen backsplash never have been so unique (two examples) if not for the artisans that Inson uses. Inson is also willing to have you be as much or as little involved in the process as you want to be. I did go with Inson to choose many pieces of furniture but realized after a certain point that his taste point made me confident in him choosing much finishing work (ex: window treatments, decorative cushions, which I love) without me. As with all design work, there are always glitches and Inson was extremely responsive and responsible for taking care of those as they came up. We are nothing less than thrilled to come home each evening and enjoy our space, which feels like a luxurious retreat perfectly tailored to us."

"I cant say enough positive things about Powers Performance Construction. They gave us the most honest quote, with full transparency as to what the materials costs - including receipts - and then were the kindest and most detailed oriented when it came to the work in our home. Client comes first for these guys. I had thought because it was a smaller job, they might not take it so seriously but these guys exceeded our expectation. 5 stars"

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.
