"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! "

"Our bathroom remodel was a huge task and Costas, Tony, and Pauly did a great job! Very easy to work with and we never minded having them in our house. Their initial quote was exactly what we paid! Definitely recommend and will hire them for future jobs!"

"Our basement needed to be remodeled which included a bedroom with bath and pantry. I reached out to Aubrey and Son because, Beau, the owner, and crew, did a fantastic job on phase one (our decks fencing and stairs). I needed the job completed within a certain time frame, within my budget, and some help with design. I already knew from phase one, that the employees were always timely and polite, and they did a great job with the phase one project. Well, they did it again !! We are very happy and will reach out again on the 3rd and final phase in the near future. Thank-you to Beau and his crew for a job well done. We appreciate you."

"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!!! "

FAQs for basement remodeling projects in Somersworth, 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.
