What Our Clients Say About LICC
"I would recommend LICC to anyone and everyone. I personally wouldn’t use anyone else. We added a pretty large addition to our home. I found out I was pregnant right after we signed contracts. I was worried about construction still going on while trying to prepare for baby. John promised me he would finish in time and he came through. The new nursery is built and decorated with plenty of time to spare. Jessica does an amazing job and is so hands on with everything that all I had to do was focus on my pregnancy. John is professional, honest, trustworthy, and fair. I always felt like I was in good hands."
Courtney R.
"I can't thank John, Jessica, and the crews of LICC enough for the wonderful job they did on my home. We reworked an old floor plan to be more open and functional and breathed new life into a dated kitchen with a complete overhaul. LICC has renewed my faith in quality craftsmanship and home repairs in general. The construction portal, their professionalism, and keen attention to detail has made me a customer for life. I can't stop raving about their work and how my house finally feels like a home!"
C. K.
"My wife and I are so happy with the job that John and his crew did for us in creating a new entryway to our house. There were a number of obstacles that had to be dealt and those obstacles were taken care of professionally and constructed with high quality. Both John and Jessica were easy to talk to and listened to our concerns with understanding and the final product could not have come out any better. We look forward to working with them again on future projects."
Joseph R.
"This is the 2nd time we used John and his team for work. This time around it was a full kitchen renovation. From start to finish, it was a very easy process. Whether we were dealing with John, his crew or the kitchen designer it was a pain free experience. I have heard horror stories of people who have had kitchen renovations from extended timelines to unexpected price increases, add ones, etc... We had absolutely none of that with LICC. I highly recommend LICC --- thanks again John!"
Todd S.
"John and his team removed my old carpeting and ceramic tile floors, and installed new wood floors and new ceramic tile. The work was completed on time, and after it was completed, you would never have known that work was recently done. Anything I wanted changed was done so almost immediately. The finished product was perfect. We couldn't have hoped for a more professional job or for more polite and professional workers. I can highly recommend John and his LICC crew for affordable and professional work."
Neil G.
"Absolutely pleased to offer a top-rate review for Long Island Creative Contracting. John and his crew renovated our basement which had serious water damage. His suggestions from flooring to ceiling to paint choices were terrific and the job was done beyond our wildest expectations. He also installed a beautiful driveway apron and completely replaced our large front porch and painted it. We have just contacted him for another job. Highly recommended. Prompt, cooperative, fair pricing and a genuine nice guy. At the job site every day."
Ginny W.
"Mr Petsco and his team of professionals were fantastic!! We had to completely refurb our basement that had a flood in the winter. He was prompt in responding to our inquiry, came to take a look and listened to our ideas...a true professional. He worked with our insurance company and our project proceeded ahead of schedule. The results of our project were beyond our expectation! We plan to use Mr Petsco in our future projects...his company is now "our contractor". We would recommend LICC to anyone for any and all projects. Bravo!"
D. O.
"We hired John Petsco to work on several projects for us. The projects involved everything from complicated trim work on our old house to masonry. He has consistently shown himself to be responsible, forthright, detail oriented and creative. John has a keen sense of being able to assess our needs and help us to actualize our ideas. Art and design are inherent in every renovation project and John's artistic ability combined with his knowledge of construction and materials is very practical when designing."
Ferdi E.
"John Petsco is an extremely professional construction artist and gets ANY job done quickly and with great communication with his clients. He delegates efficiently when he has helpers with him. He also comes back when the job detail requires it or other materials were needed due to clients requests. He has done three separate jobs for me and they are extremely well done. There is NO job to big or too small. He is also a published author. Please ask him about that."
Michael B.
"LICC did an INCREDIBLE job finishing our basement! John was the only contractor who was able to provide us with a 3D model showing us what it would look like when it was completed. The “Construction Online” app that they used made daily communication's, tracking progress, minor design changes and payments as we went along super easy. Things were done the right way, within budget and on time. We would highly recommend LICC to all our friends, neighbors and families, and would definitely use them again!"
Kevin Y.
"I can't say enough wonderful things about my experience with this group of people. From our first meeting with John till the last day, they have been nothing but great. Communication throughout the process was amazing. Attention to detail was consistent. Jessica was always there to help me with suggestions to fulfill my ideas even when I didn't know what I wanted. Richie and Junior were always professional but kind and considerate. Thank you John, Jessica, Richie and Junior for my beautiful home."
Jeanette G.
"LICC built our second story deck. John, along with office manager/miracle worker Jessica, crew members Rich and Junior were professional, personable and efficient every step of the way. The entire team went above and beyond and was a pleasure to deal with. John was at the job virtually every day, addressed any questions or concerns, and there were no surprises at the end. The deck is beyond beautiful and the quality of the craftsmanship is top notch. Thank you John, Jessica, Rich, Junior and all team members. We would use LICC again."
Therese B.
"We chose Long Island Creative Contracting to remodel our bathroom. The level of service was outstanding. I really liked the transparency of the pricing through the use of an online portal. John and his office manager, Jessica, were in constant communication with me in the weeks before the job started. I was able to approve every purchase and I was able to shop with trusted vendors. I would highly recommend LICC to anyone planning a home project."
Shane G.
"Trying to find a quality contractor that you can trust for a complete bathroom renovation can be a daunting task. I was fortunate enough to get lucky and found John Petsco from Long Island Creative Contracting. From the moment we met, John was very professional, knowledgeable and was comfortable to work with. He has a natural ability to understand space and design and was able to interpret my idea into what is now a gorgeous bathroom, above and beyond all expectations. I would highly recommend John for any of your contracting needs, and look forward to working with him again."
Elyse B.
"We chose Long Island Creative Contracting to remodel our bathroom. The level of service was outstanding. I really liked the transparency of the pricing through the use of an online portal. John and his office manager, Jessica, were in constant communication with me in the weeks before the job started. The craftsmen were talented, professional and clean. I would highly recommend LICC to anyone planning a home project."
Shane G.
"John Petsco is the best contractor I have ever used. I was never able to find a company that did high quality work, was reliable, on the job from start to finish, and fairly priced a job, until we met John. He gutted renovated 3 bathrooms for us simultaneously, and was somehow able to keep our home incredibly clean and organized throughout the process. In fact, we liked John and his crew so much, we decided to use them again, this time for a major expansion involving our living room, dining room and kitchen."
Robert P.
"I would highly recommend John Petsco and his team of building professionals from LICC. John did a basement renovation for us and created a beautiful space for our family and a work environment for a home-based clinic that I own/operate. With John and his crew you know exactly what you’re getting, with no surprises. He’s a clear communicator and puts EVERYTHING in the contract! He creates a timeline, clearly written invoices, and checks in throughout the job for customer satisfaction."
Laura H.
"John, Jessica, and the entire LICC team were extremely professional and knowledgeable throughout our entire six week project. We were impressed from the beginning with John's ability to bring our ideas into reality first with a digital drawing and then with the actual construction. We were amazed by how expertly the contractors were scheduled as to not waste any time and how Jessica immediately answered all of our questions and/or concerns. We have already recommended LICC to our friends, family, and neighbors and plan on using them again in the near future. You will not be disappointed with your results!"
