"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Working with Jose and is team was an excellent experience. He’s very dependable and reliable . He shows up on time and he works! His prices are very reasonable and his work product is wonderful. Jose was initially hired to do one project for me (renovation of all 3 bedrooms - install new ceiling light (bedroom had no overhead lighting ) repair ceiling, instal new ceiling fan, paint all bedrooms, built two custom closets. After I realized how well he worked, I asked him back to do a second project on my home, repainting the entire interior of my home, repairs to the ceiling etc. he also did more electrical work on the front of the house. He then did some tile replacement and I installed additional lights in the basement area. Based on the work my Neighbour saw at my home they also hired Jose to repaint the entire interior of their home.He’s the ONLY person I will ever call from now on for Anything I need done."

"I used K&A Home Repairs to rebuild my deck. I found them to be dependable, professional and experienced for what I needed. Anthony came at the appointment time to provide a fair estimate and followed the work schedule as close to the plan as He could, weather permitting. I am extremely pleased with my new deck and will be calling K&A for more projects on my home."

"<p>This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /></p> <p>Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. </p> <p>Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. </p> <p>This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.</p> <p>I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.</p> <br />"

"Ray Lamanna and his crew at Tri Board Construction did two wonderful jobs at our house. First, they did an amazing job replacing the floor (and a toilet) in the upstairs bathroom. Next, they painted and fixed holes in walls throughout the house. If you describe to Ray what type of tile or design you want, he'll bring you various samples to choose from. The entire crew are very respectful and leave your home in perfect order upon completing the job. I highly recommend Ray Lamanna and crew of Tri Board Construction for any work you need done in home or office."

"We hired Coco’s Custom Building on 2 separate occasions. We needed our roof redone and later decided to hire them to replace a dozen windows in our home. The owner Keith provided us with a great quote each time and was able to schedule the work right away. Any questions or concerns I had were addressed immediately which made the renovation go smoothly. I would definitely recommend Coco’s Custom Building and look forward to using them with my future home renovations."

"We recently had our foyer completely transformed by Glenn and his crew, and I truly can’t say enough good things about the experience. From start to finish, the professionalism, kindness, and customer service were exceptional. What stood out most was that there was never any pushback, every idea or question was met with “yes, we can do that,” and Glenn always approached the project with patience, confidence, and genuine care. He was incredibly accurate with the project timeline, kept the workspace clean and organized every day, and was very conscientious about working in our home. His crew was professional, respectful, and hardworking throughout the entire process. Most importantly, the final result absolutely brought my vision to life. Glenn truly made my dream foyer a reality. The craftsmanship and attention to detail are beautiful, and you can tell he is extremely talented, knowledgeable, and takes pride in his work. We are beyond happy with the outcome, highly recommend!"

FAQs for major home repair (general contractor) projects in Port Jefferson, NY

In many cases, it’s much less expensive to convert a bus than to buy an RV, especially if you’re considering a newer RV model, which can exceed $100,000.

Another huge benefit of school bus conversion is that you are in control of the renovation project. You get to pick your camper's new layout and all the appliances and furniture.

While school buses can easily cost $300,000 when they're new, you can often find used buses for just a few thousand dollars. These vehicles experience extreme depreciation due to government regulations; they can only be used for so long before they must be replaced. Due to those same regulations, other government agencies cannot purchase them for their own uses, so the consumer market is the only place they can go.

The length of time it takes to convert a bus depends on the scope of the project (and size of the bus), how much work is DIY vs. done by a professional contractor, and how much work you’re doing up front.

In general, expect at least a couple of months for a conversion, but larger conversions could take six months to a year. Remember: You can tackle projects as you go: Get the basic work done so that it’s livable, and then continue to enhance your living space over time.
