Matthew and Joe Walker from Double Check Builders did a great job on my house remodel. They were professional, flexible and they stand behind their work. They took a vision that we had and created exactly what we were looking for.
Steve and Marina, Lake Ronkonkoma NY
We have had the pleasure of working with Double Check Builders for many of our renovation projects in our home. Matthew and his father Joe are the ultimate professionals!
They communicate with the homeowner on every phase of the project. Their suggestions on a project are invaluable. The work is performed in a professional, timely and expert manner at a reasonable price. We would definitely use Double Check Builders on any future projects and highly recommend this company.
Chris & Bob, Hauppauge NY
As someone in the industry, I know I had to my homework prior to hiring anyone to renovate my garage. Of the dozen or so contractors, Double Check was the only one that requested the paperwork on the house. They subbed out the majority of the work and the overall results were a good job.
Double Check is made up of honest, hardworking people you can trust. I would highly recommend them, which means a lot coming from someone in the industry. You get what you pay for with them.
June, Centereach NY
I needed to have a room added on to my home for my son and brought in three contractors for an estimate. Double Check also came recommended from someone at my friend’s job. The cheapest price did not seem like the best idea and Double Check was competitive. We got a better feel for them than the more expensive contractor though the prices were close.
The room came out great and David and his father worked well together. I think this makes a huge difference. I was very pleased with their work and would recommend them.
Dorothy – Mastic Beach NY
I would like to take this opportunity to thank you, and your staff for helping my family and I through a difficult time. On February 3, 2013 , a car came through my kitchen. When the insurance company recommended I contact a contractor; I automatically called Double Check Builders. I had worked with you in the past(Second Floor Addition) and found your company and staff to go beyond basic support and professionalism at every instance. When this tragedy struck once again your professionalism, kindness and caring attitude during this trying time made this situation easier to bear. I would recommend your services to anyone who has suffered a loss or needs and addition to their home. My deepest thanks and appreciation.
I did some research in finding a home improvement professional to build the dormer. Joe Walker of Double Check was the President of a New York City-Long Island Chapter of NARI. He had an impeccable record and that is what mattered to me most.
The job went terrific and there were no problems at all. I appreciated them being so local, allowing him to be on site very often. Double Check took care of all the necessary documents, permits, and CO’s with the town. I was fully satisfied with the results of the dormer build and would gladly recommend Joe and Double Check.

Last summer when we began our journey, Matt and Joe were contractors. Today I count them as friends.
Scott and Ellen, Lloyd Harbor, NY
I cannot say enough about the quality of work and service we received from Double Check builders. Their attention to detail, extensive knowledge and endless patience were extraordinary. Matt in particular was extremely responsive to all of our concerns. Our kitchen and bath remodels were absolutely beautiful and we couldn’t be happier or more satisfied.
Trudi and Michael, Huntington NY
I’m writing to express my sincere thanks and gratitude for doing such an amazing job on renovating my kitchen. From the start, Matthew Walker was polite, respectful, knowledgeable and very helpful. Matthew enlisted the aid of Alex Pfitzer from Artistic Cabinetry to give us ideas of how to best utilize the existing space and helped us choose beautiful cabinets. I love my kitchen.
Matthew set up dates of when certain phases of the kitchen would take place. He was always true to his word, showed up on time and cleaned up afterwards. All the contractors that worked on our house were top rate. I would not hesitate to choose Double Check Builders again for other house projects and I recommend them completely.
