"Dave Nessel and his stellar company, Unique Construction NY Inc. are the BEST. Allow me tell you why- On May 15th 2022 at 5:45 p.m., my house was hit by, what electrical engineers later estimated, was at least 80,000 volts of lightning. That huge, direct surge of energy destroyed all the systems and contents that made my house more than four walls and a roof. In addition to the bolt of lightning destroying all the systems in the house, it caused a violent, destructive fire. Thankfully I was home at the time of the incident, or the house would have quickly burned down all the way down and my pets would have suffered a terrible fate. Still, after all was said and done what had been my home for seventeen years was reduced to nothing more than an outer shell. I was immediately forced into the position to find, hire, and organize tradesmen from all specialties, negotiate the endless complexities of homeowners insurance, all while trying to find a place to live and continuing my self-employed full-time work schedule. It quickly became clear I needed the services of a general contractor. I interviewed a couple, but as soon as I met Dave I knew he was the man for the job. Dave was always on time or early. He went through the house with a fine tooth comb for hours, noticing things and problems from the destruction I hadn't noticed. His expertise of every level of construction and understanding of all aspects of housing systems (electrical, plumbing, etc) was unmatched by anyone else I had interviewed. Additionally he had an understanding of the homeowner insurance protocols and was able to interject as a supporting role (only when needed, Dave never undermined me -I'm a single female homeowner-) with professional, easy to read, paperwork, accurately demonstrating all costs. I'm confident his detailed documentation made the long slog of negotiations with my insurance representatives a little easier. Under his expert guidance, his company gutted and rebuilt my old house to beautifully modern standards while maintaining its historical charm. The rebuild came in precisely on budget and two weeks early. Dave's company Unique Construction handled my complex situation with upstanding processional skill, old fashioned kindness, and outstanding forthrightness. Dave and his crew treated me with respect, rebuilt my home, and provided a little hand holding & TLC when it seemed I needed it and I'm eternally grateful. Anyone reading this should hire Unique Construction!"

"The entire process couldn't have gone better. Alex and his crew went above and beyond to deliver a great finished product. From the initial consultation to project completion, Alex provided great advice while being completely transparent about the expected costs, even with a few last minute changes on our part. Alex and his team even looked after my elderly dog while we were at work which helped ease our concerns about the construction process. I would recommend AMV to anyone looking for quality work at a reasonable price."

"We had two teams - one for the roof and one for the gutters. Both teams were great. Steve was the foreman for our roofing team and he did a great job at communicating with us every step of the way. The work was completed quickly and efficiently. The gutter team arrived a couple of days later and again, they worked very quickly. We were awaiting the arrival of rain barrels so we gave them the dimensions and they cut the gutters to fit and gave us additional length to slide in for the winter months. Everyone we interacted with from the company was professional and courteous."

"Scott rebuilt my kitchen. Not only did he install all of my appliances, he also built me a breakfast nook. Tiles are flushed together making the surfaces smooth and easy to clean. He communicated with me through each process of renovations and addressed all of my concerns. He also built a drainage system through my yard and both at the top and bottom of my driveway to prevent flooding. If I ever had a question, he always had an answer."

"We bought our home a few months ago, and I just want to say how much we?ve appreciated the way we?ve been treated. From day one, we felt like we weren?t just another sale. The team has been kind, responsive, and really there for us whenever we needed something. They truly care about making sure everything is right and that we?re happy. Mr. Shtienmetz is someone you can tell genuinely loves what he does. He?s involved, he listens, and he stands behind his work. It?s not just business for him, you can feel that he does this with heart. That kind of dedication is hard to find, and we?re very thankful for it. We wholeheartedly recommend them to anyone looking to purchase a home. If you want to work with people who truly care and stand behind what they do, you will be in very good hands."

FAQs for addition to existing structure building service projects in New Windsor, 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.
