We are family owned and operated with over 25 years experience remodeling homes. We pride ourselves on offering a quality product and professional service tailored to your needs. Take a look at our previous work and contact us to discuss your next remodeling project today!.

"Yes—Anthony absolutely got the job done right and efficiently. This was a complex deck project that required special permitting, coordination with an electrician, and integration with hot tub installers, and Anthony handled it with professionalism from start to finish. He went out of his way to secure a special contractor permit and was consistently communicative, proactive about potential issues, and clear about solutions. When other vendors were hesitant or negative, Anthony stayed focused and kept the project moving forward. He worked seamlessly with the electrician and hot tub team and was on site for the hot tub delivery, making the installation smooth and stress-free. The final product is beyond perfect—it’s exactly what we envisioned. High-end craftsmanship, exceptional value, and a true professional. I would recommend him without hesitation."

FAQs for major home repair (general contractor) projects in Mastic Beach, 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.
