"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

" I had an excellent experience with Ideal Solutions on my basement remodel. From start to finish, the team was professional, communicative, and detail-oriented. The quality of the work exceeded my expectations, and the finished basement turned out even better than I imagined. Everything was completed on time, and they made the entire process smooth and stress-free. I would absolutely recommend Ideal Solutions to anyone looking for basement remodeling or home improvement work."

"We have been wanting to finish our basement for a very long time now but the prices we were given were too high! A friend of ours referred DCL to us and we thought we would give them a shot. The price was right so we started shortly after. They took care of all the paperwork and permits needed! Bob was there for the whole process discussing with us every step of the remodel! Very knowledgable and very well trained team! Our basement looks incredible and we enjoy spending time there! I would recommend DCL to anyone!!"

"Jim was excellent! Jim added a new bathroom to our attic and built a new laundry room in our basement. He helped us develop a plan for the entire house and gave guidance without being pushy. Jim and his subcontractors were always friendly to our family and our pets. I highly recommend Jim and plan on having him do future projects."

"I would not hesitate for a second hiring Horsman Builders for any of my house projects or remodel, in fact that is what I will do from now on. I was nervous starting a project having to handle things on my own but Tim made me comfortable with a detailed estimate, answered all my questions, kept me informed about the work, the site was always clean and the result is awesome, my neighbor was commenting on how great it is just checking it out from a window. Fair price, excellent quality and great customer service. A+"

"Pro Warrior did an amazing job on our house renovation. Yann’s crew is the hardest working crew I have seen. They were here from 7:30am till 5:30pm everynight they came. The fine details with the siding , trim and metal work was amazing by them. Our house looks so updated and modern. Looks like a brand new house. We highly reccommend Pro Warrior for any construction needs."

"Pros: 1)Very easy to work with the guys. 2)Returned phone calls in a timely manner. 3)They were able to adapt and work with contractors performing other tasks on the property. 4)Jill (the painter) did an excellent job. Cons: 1)Estimate had a line item for delivery of dumpster which was not delivered but we were still charged for it. 2)Estimate called for pre finished white oak but red oak was used. We were okay with this but the point is, what was specified in the original estimate was not what was used. 3)Quality of work was not superb. A flooring contractor would have been better.

FAQs for basement remodeling projects in Newmarket, 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.
