"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.

"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."

"I cannot say enough great things about Benchmark Home Improvements! I needed my kitchen remodeled and decided to give them a call based on the excellent reviews I had read about them and those previous reviewers did not steer me wrong. Lee is very personable and he really took his time explaining the services he offers and helped me decide on a plan to make my kitchen work for me. I decided to have my cabinets refaced, turn a closet into a great looking pantry and go with a custom built in microwave in my lower cabinets to make room for the chimney vent hood I wanted above my stove. I feel the price was great for the work I had done and the customer service and level of professionalism is second to none! A special thanks to Pete as well! His personable nature, professionalism, careful workmanship and attention to detail are greatly appreciated....and the pups thank you for the treats! :)"

"I used Remodel Or Renew Home Improvement to replace a door I had installed not long ago. I had water coming in and the old contractor was nowhere to be found. The owners Tom and Mike came to my house identified the issues and had a crew here the next day. I cant recommend this company enough. I was loosing sleep with water coming into my basement. I have new confidence in good people to do great work! Thank you Remodel or Renew! Exceptional service at a reasonable price."

"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!!"

Small jobs welcome

"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 Seabrook, 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.
