Construction Company reviews in Port Washington, New York

John and team helped us fix our home after the recent winter freezing that impacted many homes on long island. John and his team were able to come in assess the damage, provide a detailed report and work with me to get it all settled with my homeowner insurance company right away with no hassle. John's team detailed plan and assessment allowed my insurance company to very quickly sign off on the work and provide the funds within a week of the accident in order for John and his team to fix alll the flood damaged areas quickly. I would recommend 915 construction to anyone who wants a contractor who is honest and helps you each step of the way through a job so you always know where you stand in the process.

915 construction is the absolute best. They have renovated almost every room in our 1938 Tudor, built an extension, and created outside structures that all look just like the original house, and done it with meticulous detail and passion. They have delivered on all areas: framing, roofing, flooring, electrical, heating, plumbing, etc. The team is trustworthy, consistent, and follow through on all aspects of construction and design.

John and his crew did an amazing job on my bathroom remodel. All the elements I wanted are there and it looks beautiful! This was such a a painless process and the crew did an incredible job of cleaning up as they went. I will definitely be using them next year for my kitchen reno!

We had the BEST experience working with 915. John has extreme attention to detail and is very personable, making the chaos of a full gut renovation much easier to manage. He is very responsive and makes himself available at the drop of a dime, before and after the project. The entire team and their subs are professional, friendly and feel like part of our extended family. They were so supportive of what we were experiencing personally, as we had our first baby during the renovation, and did everything they could control to accommodate us and expedite the project. They are the epitome of working with speed while not sacrificing quality, a rare trait in this industry. We've recommended them to our closest family and friends, something that we take seriously as home renovations can become high stress; 915 was our partner the entire way and ever since. They still come by our home two years later!

915 Construction is the best. They have worked on several projects of mine but probably the most impressive was the largest project they did by turning my ranch into a Dutch Colonial. Not only was the work fantastic but they finished it in less than 3 months which is unheard of. Their work is great and they are super professional. If you need a small or big job done, 915 Construction is the only company I'd use!

When we bought our house, we knew we needed to redo the kitchen and we are so glad that we used 915 to complete our renovation. From the design stages, materials selection and quality of work everything they did was top of the line. We bumped out our kitchen, renovated our bathroom, and added a new laundry room and they finished everything beautifully and ON TIME - something I had heard was never possible with construction but they did it. Working with these guys is seamless - always reachable and always on top of everything. I cannot say enough about the work they do and have recommended them to many of my friends who all agree they are the best.

Ever have a honeydo list, without having a honey to do it? Well, in my case I have a honey who has no idea how to do the little things around my house. That's when John and Jaimie and their team comes to the rescue. It 1st started out with a honeydo list of odds & ends around my home. And as with any home, things begin to creep up on you and the list becomes longer, with bigger jobs to get done. Handyman Express/915 Construction has never let me down. From recaulking my shower, painting my living room, fixing a leaking roof, to installing a beautiful outdoor brick patio deck. They have ALWAYS done an excellent job and I couldn't be happier with the services they have provided to us over the years. I highly recommend them! (And yes, I am a REAL client of theirs...)

Jaimie and his team are fantastic! Great experience from start to finish. Honest, skilled, and takes pride in their work. I’d absolutely recommend them.

I couldn’t be more impressed with the incredible job they did on our home renovation. From start to finish, their team was professional, reliable, and truly skilled at their craft. Communication was seamless, timelines were met without delays, and the quality of their work exceeded all expectations.

What stood out most was their attention to detail and commitment to getting everything just right. Whether it was structural work, custom finishes, or final touches, everything was done with care and precision. The crew was respectful, cleaned up daily, and made the whole process far less stressful than I imagined.

I highly recommend them to anyone looking for honest, top-notch construction work. You can trust them to treat your project like it’s their own.

We have used 915 Construction & Design for a couple of home projects. Most recently they expanded/redesigned our kitchen. The workmanship is excellent and was done in a timely manner. The crew was professional, courteous and friendly. John Keffas and the office staff were always available to answer questions or address concerns. I would not hesitate to use their services for any home project in the future.

John and 915 Construction have been amazing to work with, and we plan on doing more work with them! John and all the very skilled workers and engineers were extremely professional and did a fantastic job on our kitchen upgrade. We trusted them in our house without us present, and our kitchen turned out better than we had hoped. John was extremely responsive, and he worked quickly to provide solutions unexpected issues. The 915 Construction team took responsibility for our kitchen and completed all upgrades beautifully, and without much disruption - we worked from home many days without many interruptions.

I cannot say enough great things about John Keffas and 915 Construction and the incredible job they did building our outdoor pavilion! From start to finish, the entire process was smooth, professional, and exceeded every expectation we had.
From the very first consultation, John impressed us with his clear communication, thoughtful design ideas, and attention to detail. He really took the time to understand what we wanted and offered creative suggestions that elevated the project beyond what we imagined.
The craftsmanship is simply outstanding. The structure is beautiful and clearly built to last. It's not just a pavilion—it's a showpiece that has transformed our backyard into a stunning and functional outdoor living space. We've already hosted several gatherings, and every guest has commented on how impressive it is.
What stood out even more than the quality of the work was the professionalism and integrity of the crew. They were punctual, respectful, and kept the job site clean and organized throughout the entire project. The project was completed on time and within budget—no surprises, just great results.
If you're looking for a contractor who truly takes pride in their work and delivers excellence every step of the way, look no further John Keffas and 915 Construction. We’re beyond thrilled with our new pavilion and would recommend them to anyone without hesitation.

Where have you been all of our life?! We are so grateful to Jamie and the entire team at 915 Construction and Handyman Express. They were recommended by a friend who did a major renovation and loved the work! We could not be happier with how they transformed our home, inside and out! We wanted an experienced, reliable builder who would care for our home as much as we do. Estimates were prompt, communication was excellent throughout our project. We did a new exterior, windows, doors, new flooring, a basement renovation, ceiling redesign and lots of built ins. The team has expert craftsmen and work with the best partners. We worked within our budget and the inevitable change orders all made sense and were thoroughly explained. Jamie has a strong design sensibility and made thoughtful suggestions. Upon completion of our project we’ve retained Handyman Express to do some other projects we had been putting off. They are now indispensable partners in the care and maintenance of our home.

We had an absolutely amazing experience with 915. From the start of our job until the very end Jaimie was thorough, honest and extremely detail oriented. He stuck to his timeframe and managed all changes that we added to the job smoothly. His initial estimate was also fair and accurate as he was able to predict potential complications and anticipate our needs in ways that others may not have. He was readily available, communicated regularly and worked hard to create a great partnership with us and our designer. The professionalism, craftsmanship and dedication of all members of the 915 team helped us create our dream home. We are so grateful to Jaimie and 915 and we are excited to keep up this relationship as they help us maintain our house for years to come.

The two Juan’s did a full renovation of my 100+ year old house. When the inevitable issues occurred after opening the walls, they came up with fixes that were much better than I was expecting or thinking about. Workmanship was good and the work was done essentially on the expected timeline. Both partners were easy to reach by phone and one of the two were at the site most days and were in contact with my architect whenever clarification was needed.
