"They showed up on time each day, were very knowledgeable of the work they performed. Showed up for the quote when we scheduled the first meeting and we were very impressed with the overall experience. The deck they built was spot on and perfect for our needs. They did make some recommendations as to how it would look and work better for us and we went with their decisions and are so happy and impressed. They were very neat about their work and very easy to talk with. I would never use anyone else, and HIGHLY RECOMMEND them for whatever you need. So great to work with."

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"We hired Rich with RAM Construction to complete a major renovation to our property. With my husband being a contractor himself but having no time to do the work, this was a big step to take on our behalf and we needed a contractor we could trust to show up and complete this major renovation. Rich took the job on knowing full well what challenges may exist with working at another contractorâ s home. Rich was completely open to my husbandâ s suggestions as well as being able to provide his own ideas on how to complete the project. Even though we had a contract Rich has been very accommodating with allowing us to veer outside of the project specs. Rich has been great to work with and we recommend him 100% to anyone who may be looking for a great Contractor."

"The company (Black Dog) was hired to expand the bathroom and part of the basement renovation. The project started in October 2020 and it is still going through May 2021 with an unclear restart date after 2 no shows. It was promised to finish by Christmas. The company used 2 different colors of grout in the same room. They are planning to come back and redo it, waiting for 2 months now. They do not want to spend time on fixes. Leakage around the shower was noted, they promised to contact the subcontractor, but I have not heard from them yet. There are minor things missing, would pay attention to their contract as they may not do things like shelves installation as originally discussed. They seemed professional on initial evaluation and at the beginning, but now I am regretting that I hired them."

"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 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.
