"I was so happy with my previous bathroom remodel from Extreme Makeover I hired John again to do another Project on the upstairs bath. Again, the results were better than I anticipated. John Leahy, owner and his associate John produced a beautiful and updated look. The craftsmanship was impeccable and they were always on time and finished the project earlier than promised. John is very courteous and approachable and is easy to relate to. I know you will be very pleased with Extreme Makeover for your next home project."

"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!!"

"The crew showed up on time and talked about the project and accomplished my painting needs very quickly. I do intend on hiring them again for other home projects I require, as they also listened to my needs and responded very well to some renovation I will be doing. The current job was done very well, smooth paint, and no bubbles or flecks. I'm a happy customer."

"I HIGHLY recommend Pro Warrior! I've hired them for many jobs already as they are responsive, affordable, and proactive. I had them replace my roof and siding - I am obsessed with the results to say the least. I hired them back to complete a finished basement. Pro Warrior is the absolute best around."

FAQs for basement remodeling projects in Newton, 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.
