"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat.

"Peter has great attention to detail and is extremely meticulous with his work. I felt that Peter went above and beyond with our deck remodel project. He was very consultative with the material selection and provided options and suggestions that most contractors would have overlooked. I highly recommend him and plan on using him again for future projects."

"This being our first experience with a contractor, we could not have been more happy with our selection. Sean and his team are professional, trustful, fair pricing, identified issues on the walk through, flexible to scheduling, friendly to Veterans and fast at their craft. We did an entire demo and remodeling of the bathroom, kitchen, flooring (bath, kitchen and hallway) as well as 6 foot wall gap and reinforcing support beam. Pricing was within budge and the contract was detail. Payment was made weekly with detail sub-billing, that made it easy to review work and mark progress. Continue communication made it easy to id issues, coordinate purchases of items and keep up with timeline. Sean even went out of his way to assist me when pipes froze during weekend that my husband was away on business which save potential damage to the home. We highly recommend Handy and Some, LLC for any project you have in mind and we will reach out to them on all of our future projects. I am wicked happy with my bathroom and kitchen. Thank you Sean, the team and Handy and Some, LLC"

FAQs for basement remodeling projects in Hampstead, 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.
