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."

Basement Remodel questions, answered by experts

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.

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.

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.
