"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."

"John was excellent and I highly recommend him. He rebuilt our breezeway and installed a beautiful wood ceiling in our family room. In particular, John: - was immediately responsive to our request for a quote; -provided the quote when he said he would; - followed up and answered questions we had; - provided an additional quote based on changes we made; - started the project when he said he would; - showed up every day; - minimized any inconvenience to us while working; - worked neatly and cleaned up every day; - completed the project on time and on budget! Working with John was a very pleasant experience. He is friendly, courteous, professional and an excellent communicator. His mantra is to make the customer happy. He checked with us at each stage of the project to be sure we were pleased. He is very detailed oriented and his work product is top notch. We would, and plan to, use John for future projects."

"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!"

"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. "

"They are very good at what they do. We re-hired them after they did a job for us over last summer. There were differences on a this second job. If you use this company, I recommend: 1. Insist on a thorough, detailed contract that specifies ALL the details. Several things were forgotten, and later treated as ;added and as scope change. Could have been avoided with cleaner communication. 2. Specify in writing whether or not sub-contractors will be used for the job. During this second job, we had a couple of sub-contractors that were really, really bad. a. If sub-contractors are used, recommend specifying that a crew chief from Ideal be on site at ALL times. If needed, they should provide translation services. Our place was trashed when they left the site; sheet rock dust everywhere, floors to scrape, a hole in the wall to fix, lots of hard work ahead. They knocked off $2K. I would not do this amount for $2K. Bottom line, do not feel it was an fair solution. Learned a lesson."

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.
