"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"As a testament to how happy we were with our first renovation provided by the Curtice Group in 2021, which provided completely new kitchen/dining/mudroom/bath, we hired Scott and his team again in 2024-25 for another major renovation. This job was composed of 3 main parts: a gut remodel of our main bathroom, renovation of a large attic space (about 700 sq ft), and whole-home conversion from steam radiators (gas) to heat pumps including removal of all radiators and a chimney. The bathroom now is attractive and more functional, the attic adds a large amount of useful space as an office/kid room/guest area, and central air makes a more comfortable climate. I’m a big fan of the design/build concept, because you really don’t want to separate those two elements into different contractors, and if you find a talented company, they can handle all aspects of the job fluidly. Scott Curtice has a real knack for design, he is attentive and cares about details, and he will perform carpentry and touch-up work as needed. Moreover, he handled all the project coordination so that we could do the jobs that we do well, which do not include home renovation."

"Stephen helped us renovate our condo in Boston in 2021. The work included complete bathroom renovation, electrical work, and building new closets. He found great contractors who did an amazing job, he also took care of all the paperwork/permits/building management, and helped to select and buy all the materials and appliances. He is proactive, professional and helpful, and I'd certainly recommend working with him."

"We had the pleasure of working with D. A. Kinsella Company to develop concept designs for a new home addition. Their architectural team was quick, professional, and came up with many detailed ideas to help ensure that we were happy with the design. David successfully coordinated with the city to determine project requirements early in the design phase, which was very helpful and saved us valuable time and effort. We highly recommend David to any homeowner considering a home redesign or new addition...!"

FAQs for major home repair (general contractor) projects in Chelmsford, MA

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.
