"Custom Construction did an excellent job painting bedrooms and hallway walls, ceilings and trim and bathroom ceiling. They contacted us quickly with an estimate, and responded promptly during the job. Very professional and courteous, on time, cleaned up every day. They were meticulous with their work and their crew finished efficiently. We are very happy with the work they did and would hire them again. Highly recommend them"

"This was a huge job - the basement is 1400 sq ft and needed a complete rip (it was an old doctorâ s office), new plans were drawn up and they handled everything from start to finish. The work was excellent and they kept to schedule. Really happy with the outcome of the project and would definitely recommend."

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

FAQs for basement remodeling projects in Block Island, RI

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.
