We are committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

"I wholeheartedly recommend Mr. Michael Sabella for his outstanding work as a contractor on projects involving the expansion and renovation of my residence. Michael first collaborated with me over 20 years ago when he undertook a second-floor bathroom remodeling project. His expertise and commitment to excellence were apparent from the outset, delivering exceptional results that left a lasting positive impression. Five years later, I contracted Michael for additional work, entrusting him with the extensive remodeling of the first floor. This encompassed a comprehensive transformation, including the remodeling of the kitchen, living area, a bathroom, and a bedroom. Once again, Michael's dedication to his craft and his ability to bring innovative ideas to life were evident throughout the project. In the last ten years, Michael undertook the challenging task of adding a two-level expansion to our existing house, encompassing a total of 400 square feet on each level. His expertise and attention to detail were evident throughout the entire process. On the second floor, he successfully updated the kitchen and seamlessly integrated it with the existing living area, creating a harmonious and functional space. One of the key aspects that sets Michael apart is his ability to assemble a highly skilled and qualified team of contractors. From electricians and plumbers to painters, flooring specialists, and tile workers, every individual involved in the project exhibited a level of professionalism and proficiency that exceeded our expectations. The coordination and collaboration among the various trades ensured a smooth and efficient workflow. Not only did Michael excel in the interior renovations, but he also demonstrated exemplary project management skills in overseeing the construction of a retaining wall and a two-tiered drainage system around the new addition. This strategic approach was implemented to prevent runoff water from entering the first floor of the addition, showcasing Michael's foresight and commitment to ensuring the long-term integrity of the structure. Throughout the entire duration of the project, Michael was a constant presence on the job site. His hands-on approach and proactive involvement in directing the contractors underscored his dedication to delivering high-quality results. His leadership style fostered a positive working environment, and his effective communication ensured that all aspects of the project were executed to perfection. In conclusion, I wholeheartedly recommend Michael Sabella for any construction project. His professionalism, attention to detail, and ability to assemble and lead a skilled team make him an exceptional contractor. I am extremely satisfied with the outcome of the projects, and I am confident that Michael's expertise will bring success to any future endeavors."

"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

"JM did a fantastic job. About 13 years ago, while living at our previous residence: JM remodeled and modernized our full Kitchen, two full bathrooms and, after many tries by other contractors, he was able to stop a leak from our roof at no charge. About 10 years ago, at our current residence , JM remodeled and modernized our full kitchen and did a unique job of updating 4 large sliding closet doors. He removed the cheap inserts, and replaced them with 1/4” high quality plywood into the frames. He then, using wood molding, he made the face of the doors look like real wood doors. Doors were stained and look like expensive oak doors! JM comes up with excellent suggestions, alternatives, and expense saving ideas. We plan on relying on his expertise when we’re ready to upgrade our Patio. All the best to JM Group!"

Basement Remodel questions, answered by experts

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.

A finished basement does not always count as square footage, though this varies by state regulations. You may live in an area that allows for below-grade spaces to be considered in a home's official square footage. In those cases, the basement must meet certain conditions, like having a functional egress and being a livable space with flooring, finished walls, and temperature control. Your local assessor can confirm your area's policies regarding basement square footage.

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
