"We had an outstanding experience with Owens Corning Basement Remodeling from start to finish. The entire team was phenomenal—professional, communicative, and truly dedicated to delivering high-quality work. One thing that really stood out was how quickly they got started. There was no unnecessary waiting, and they stayed on schedule the entire time, which made the whole process smooth and stress-free. A special shoutout to Carlos and Luis, who worked tirelessly on our basement. Their craftsmanship, attention to detail, and strong work ethic were obvious every single day. They took great pride in their work, and it absolutely shows in the finished result. We couldn’t be happier with how everything turned out. If you’re considering a basement remodel, I highly recommend Owens Corning—they exceeded our expectations in every way!"

"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"We had a fantastic experience with this company. Joe (the owner) was responsive, constructive, easy to work with, and reliable, and he did very high quality work. We had a quite extensive basement finishing project (finishing about 50% of a previously unfinished basement) that involved planning the use of the space, adjusting the plumbing organization to accommodate the bathroom we wanted to put in, installing electrical circuitry, installing the bathroom, rebuilding the stairs, installing a substantial network of soffits to enclose ducts and plumbing, and of course installing all the drywall, flooring, finishing etc needed to complete the space. Throughout the project Joe stayed in touch with us about plans and choices, and was flexible about accommodating our preferences while also giving us sage advice based on his (extensive) experience. He started on time and completed the work in line with the expected schedule. Joe did much of the work himself but he also brought in other specialists as needed, on schedule and with minimum fuss (plumber, electrical, etc), and he handled interactions with the town inspectors effectively too. He even helped us with some issues elsewhere in the house that came up while he was working on the basement, and came back to help us install some decorative items that we ordered but did not arrive before he officially finished. We are extremely happy with the end result and use the space almost every day. Anyone who sees the space is also very impressed. It's a wonderful addition to our home and exactly what we hoped for."

Basement Remodel questions, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.
