"

We recently had my bathroom remodeled by Homecraft Remodeling in Plainview, NY. The quality of craftsmanship and the professionalism of all involved are exceptional.

Getting estimates, listening to varying opinions and making decisions that affect the value of your home can be daunting without an honest, experienced professional to guide you.  Finding a Contractor to come into your home and demolish a room and put it back together with sensitivity and care can be difficult. We were lucky. We found Norman Gavin who treated us with integrity and fairness throughout.

Although we were confronted with understandable delays, caused by conflicting schedules that extended the job a few days we are ecstatic with the result. Any issues that came up were dealt with quickly and honestly.

We have the highest praise for all who helped make our dream a reality and highly recommend you consider Homecraft Remodeling as your Contractor of choice for your next project.

"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."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"I am incredibly thankful to Ray LaManna and Tri Build Construction for my new roof. I had major structural damage to my roof due to improperly installed solar panels. Not only did Tri Build diagnose the leaks before the repair, they fixed it in record time. It was extremely reassuring to know what the cause was and how it would be resolved so that I would not have to worry about my home, my greatest investment. If you have roof damage due to improperly installed solar panels, or if you’re looking for a new roof and need a competent and honest contractor, you need Tri Build Construction, a U.S. Veteran owned company."

FAQs for major home repair (general contractor) projects in Central Islip, 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.
