"I have hired New England Carpentry several times for various projects, including facade repairs and repaint on a 3-story multifamily property in South Boston to replacing deck railing and balusters to building out a washer/dryer door frame to fit a larger set of machines. Gil has always been responsive, reliable, and fair. He always worked through what his client wanted but gave recommendations to save cost without sacrificing quality and look. Gil is trustworthy and my go-to for any project. This review is also after some time has passed and I can confirm his quality work holds up. "

"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

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.
