"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 the need to renovate/remodel our Master Bathroom, 1st floor bathroom, and our kitchen. We started interviewing prospective contractors, which in its own is a challenging experience. Some people acted like they wanted the job, others postponed appointments or cancelled all together. Bob Ayotte came to our home, sat down with my wife and I and listened to what we wanted, or at least what we thought we wanted at that point. He offered some ideas and concepts, but deferred to our vision. He took the time to visit each room, the spaces below them, the spaces above them, the wiring, the plumbing, the ventilation, etc. with an attention to detail. He asked lots of questions, took in my answers and my wife’s answers, which at times opened our eyes because our answers didn’t always match. There was never a sales approach, just a consultative approach. By the time he left, I said to my wife, “If his price is in the ballpark, and his communication and follow up on the proposal is professional, we have found our contractor.” Indeed, the price was in the right range, and the communication and follow up could not have been more professional. Bob delivered everything when he said that he would. He took the time to walk us through the proposal and answer a great number of questions. We came to agreement and decided to move forward. My experience with people who own their own companies is that I run into many people who are either “artists”: people who gifted in their craft who fail at running the business aspect including communication, or “business people” who are great at running the business, but fail at the art of their craft. Bob was so good at the business aspect, that I legitimately worried about his ability to deliver on the art. If you share that concern, or my view on artists vs business people, let me assure you that Bob is both. We tackled the master bath first, as a separate project. Everything went exactly according to schedule. We met with Bob’s tile subcontractor, Brian at Nashua Tile Center. We picked out what we wanted, and awaited his estimate. My wife chose some very nice tile, and we ended up $900 over our expected budget…$900 over Bob’s original estimate. Over the course of the remainder of the projects, this would be the only cost over-run which was not due to us adding some new scope of work, like deciding on a bench for the shower, or for a glass shower door instead of the original shower curtain concept. We more than made up for that budget over-run in credits that came back to us in other areas, including being under budget on tile for our kitchen and 1st floor bath (which of course, allowed us to add more scope to the job anyhow). All in all, aside for things that we CHOSE to add to the project, we were roughly $200 over budget for all three rooms: Master Bath, 1st Floor Bath, and Kitchen combined! The Master Bath Project from start to end took 4 weeks, just as Bob had outlined for us. It was delivered on time, and within budget. Further, his sub-contractors for tile, electrical, plumbing, plaster, painting and floor refinishing treated our home with great respect throughout the process, always taking time to prepare the area for work, protect our floors, take precautions to control dirt and dust, and to clean up every day when the work was done. Bob’s crew of himself, Mike, and Austin were friendly, knowledgeable, and hard working. I worked from home throughout the entire project, so I saw first-hand how they went about their business each day. The finished product, our Master Bath, is amazing. Friends who have seen it say that it looks like something they would find in a spa. The work was fantastic. All permits and inspections were handled by Bob and team, and they were flawless. We were excited to move on to the kitchen and first floor bath. A friend of mine had helped me with my kitchen cabinets, so they were supplied independently. Everything else went according to plan. As I stated above, the same crew from Ayotte Home Improvements, and the same sub-contractors came in, treated my home and my family with great respect, and delivered the job on budget, and on time. Bob went out of his way on several occasions to help me out with items that came up where he could either save me some money on something, save me time on something, or just help me to move a fridge, or remove a fridge, just a bunch of items that he really didn’t have to do, but he did because I believe he is just genuinely a nice guy who wants happy customers and successful projects. Toward the end of the kitchen and bath project, it became evident that we would be foolish to not extend our new colors and woodwork into our dining room and living room. Bob just rolled with the changes, managed his sub-contractors and adjusted accordingly as we added scope (and cost). He was incredibly patient with us. Throughout the entire process, the professionalism and communication never waned. Bob and I exchanged emails and text messages on a regular basis. The artist and the business person never conflicted. The project plan was accurate each week. The payments and dollars owed were always correct. This project went so well, we have Bob and his team back to add a two car garage and mud room now."

"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. "

FAQs for basement remodeling projects in Amherst, 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.
