"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."

"Torin and his team did a wonderful job upgrading our original 1980s kitchen. He was flexible with its construction ‘quirks’ and helped me find materials within my budget. Kitchen remodel included cabinets countertops & lighting. Torin is detailed and thorough. He shows up on time, is clean and personable. Throughout the project, he took on smaller fixes including replacing my bathroom faucet, fixing the drafty front door & hiding the TV cable wires behind the wall. Overall very satisfied with his work. "

"Justin came over early on a Sunday morning to assess damage to our bathroom drywall. He completed the restoration job over the next few days. He was prompt, clean, and let us know when he would arrive. The job was done beautifully, and I would not hesitate to hire him again! "

"We are very impressed with XCC and their team. Our property is very challenging and there was now solid ground where the deck was being installed. XCC built us an amazingly beautiful and solid retaining wall. We absolutely love our deck. They even went ahead and added an extra landing for my elderly mother to take a rest on. We will definitely be calling them again when we are ready to update the deck on the main house."

FAQs for basement remodeling projects in New Boston, NH

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.
