"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

"We bought our first home this year and absolutely love it, but we quickly learned it needed more TLC than we realized. We could see rot on our exterior trim and clapboards, plus a missing gable vent. From the very beginning, Shawn impressed us. His estimate was incredibly thorough, and it was clear he’s a true professional. As new homeowners, we felt confident putting our home in his hands. We are so fortunate we hired him. Shawn showed up early, worked late, and demonstrated meticulous attention to detail in everything he did. When we discovered the rot was far more extensive than we thought, he never made us feel stressed or overwhelmed—he walked us through our options, offered solutions, and helped us make the right decisions for our home. The quality of his work speaks for itself, but just as important, his communication, reliability, and integrity made the experience exceptional. We will be working with Shawn for all of our home’s needs. We actually missed him when he left ! "

"Dave and Steven did a wonderful job finishing our basement into 3 new areas, an office, workout room, and storage room. They also did a great job with installing our new electric fireplace. Estimates were provided within a day, the job started and finished on time and Dave handled all the subcontractors and inspections with ease. I highly recommend them and they'll be the first ones called when we need additional home improvements. "

FAQs for basement remodeling projects in Dover, 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.
