"We are so happy that we hired Benchmark to remodel our kitchen! Lee and Ian were professional and knowledgeable, from beginning to end. We were very impressed with their attention to detail. They made our 1980's dingy, dark kitchen look amazing with beautiful white cabinets and granite countertops. We love it! I highly recommend Benchmark and will recommend them to my family and friends. Thank you, Lee and Ian! Sallie and Don M."

"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."

"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 a consummate professional from start to finish. He gave a very detailed quote, patiently answered all our questions, and started the project weeks before we ever thought we'd get a contractor to start. The work was fantastic. Our basement came out beautiful and Jim was a pleasure to work with. He did everything exactly as designed, communicated progress, and was very responsive if we needed anything. He was also very knowledgeable about the various options for finishes, flooring options, etc, and even had some contacts with local businesses that gave us good prices for some of the materials. I highly recommend Hamil Improvement for any remodeling project. Would definitely work with them again!"

"Boyd Building had done some work for us in the past so when we needed a major deck and porch rebuild and finish, we knew Shawn would be the only one to call. Shawn always goes above and beyond in planning and executing our projects. He once told me that he puts the same amount of quality and care into the work he does on a customer's home as he would on his own home and I truly believe him. His work is detailed and meticulous. The job he did remodeling our outside space is top quality. There is not one thing we had to question. We love everything! Beyond that he is reliable, honest, trustworthy, hardworking and a really nice guy. We can't possibly recommend Boyd Building any higher! 5 stars don't seem like enough! "

"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+"

"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 Stratham, 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.
