"He did an awesome job. The stairs came out just as I imagined. He made basement stairs to meet code. This was not part of the original project request. He was very friendly and professional. He was on time and cleaned up before leaving for the day. I am very satisfied with his work and would hire him again."

"Bob was amazing throughout the entire project. Was very knowledgeable about everything we requested and helped with the planning process from beginning to end. Gave extremely realistic cost and timeframe. Was extremely professional the entire time and always made sure to clean up and it never felt like we were in the middle of a “construction sight”! We were so happy with his work that we are planning more projects. I would not have any hesitation in recommending Bob for a project. You won’t regret it!!! "

"I have had contractors in the past, shoddy work, don't show up, etc. Roberto Martinez and partner Dave were exceptional. They told me 2 weeks and it was done. They don't take breaks, hardest workers you could ever want! They moved furniture as needed, cleaned up, and did a super job on insulation, sheet rock, sanding, mudding and painting. You will never regret hiring him. He also does floors and windows and my neighbors are lining up to call him. Thank you so much Roberto and Dave."

FAQs for basement remodeling projects in Peterborough, 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.
