"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!"

"We hired Tom for a kitchen & half-bath remodel in 2019. As with all remodeling projects, especially a kitchen remodel that disrupts your life, Tom was wonderful at communicating and kept the project on time and on budget. Tom stands behind his work and quickly remediated any issues (which are always inevitable with these projects) and we can absolutely say that we are still 100% satisfied a year later. We completely trusted Tom to make our kitchen remodel dream come true and would hire him again should another project come up!"

"Everything went well.? Bob and his crew are true professionals.? I had a few ideas about how I wanted the basement to look but wasn't sure? how it could be done in a relatively small space.? I live in a condo/townhouse and only wanted half the basement finished.? Bob was very helpful with his design ideas and I was totally impressed with the results.? He exceeded my expectations by finishing the task on time and maybe a few days early.? He is very upfront with costs, expectations, and time management.? He frequently updated me with his teams productivity and wanted my input regarding such.? The results are fabulous!? My friends have complimented the fact that I still have plenty of "storage space" in the unfinished part of my basement and a beautiful room in the other.? This room consists of a reading nook with under-the-bench storage and above shelving; a small office area; and a room for watching t.v. and entertaining.? I chose to do the painting myself...Not an easy task but Bob was there to answer my questions about that as well.? Once the carpeting is in I will have beautiful pictures to share with family and friends.? I couldn't be happier and will definitely call this company for my bathroom and kitchen in the future."

"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."

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

FAQs for basement remodeling projects in Groton, MA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
