"They did a wonderful job, and I could not have been happier, with the work they did and how easy they were to deal with."

"Yes—Anthony absolutely got the job done right and efficiently. This was a complex deck project that required special permitting, coordination with an electrician, and integration with hot tub installers, and Anthony handled it with professionalism from start to finish. He went out of his way to secure a special contractor permit and was consistently communicative, proactive about potential issues, and clear about solutions. When other vendors were hesitant or negative, Anthony stayed focused and kept the project moving forward. He worked seamlessly with the electrician and hot tub team and was on site for the hot tub delivery, making the installation smooth and stress-free. The final product is beyond perfect—it’s exactly what we envisioned. High-end craftsmanship, exceptional value, and a true professional. I would recommend him without hesitation."

"I cannot say enough wonderful things about Keith Coco and his team! From the very beginning, they listened to my ideas, understood my vision, and then brought it to life in a way that completely exceeded my expectations. They built our gazebo and pool deck, and the craftsmanship, attention to detail, and quality of their work are absolutely incredible. What I had pictured in my mind became even more beautiful than I imagined! Keith and his team were professional, knowledgeable, hardworking, and truly took pride in every detail of the project. It’s not always easy to find a company that delivers exactly what they promise — and then goes beyond it — but they absolutely did. We couldn’t be happier with the finished result. Our backyard has been completely transformed into a space we are going to enjoy with family and friends for years to come. Thank you, Keith Coco and team, for taking my vision and turning it into something even better than I dreamed! I would recommend them without"

The company was incorporated in 1986 by Dominick and Cynthia Mupo and son, Michael (master plumber). Since the year 2000, it has been administered by Michael, as President and Louis, also a son, as Vice President. Manuel Machado makes up the third operations team member & has been with the company since its inception. Corporate offices are maintained in Selden and Huntington, NY. Dominick now serves as Executive Director of Sales, Contracts and Customer Relations. Dominick has been seated as a board member in the NYC/LI National Association of Remodeling Industry (NARI) since 1994. The philosophy of professional service combined with quality craftsmanship has proven to be the catalyst for our success. A key ingredient in the success of the projects undertaken is employment of a staff of diversified specialists. Almost all the construction activities are performed and coordinated by our full time staff. Occasional subcontracting is done when necessary. Working for many years with architects and designers has added valuable insights to provide the flexibility for creativity encouraged by the firm, with personal fulfillment for the client. Planning, Design and Construction Management are elements which contribute to the success of our projects. The company's original area of specialization, Custom Baths and Kitchens, have expanded over the years to include medium to large home dormer and extensions. There has always been a strong committment to handicapped and special needs clients. Our website contains a limited gallery of completed project photos and testimonials.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.
Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.
You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website.
Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
