"Beware. Have extremely detailed plans and specifications. This contractor makes everything a change order at exorbitant prices. The remodel of a condo unit took over 18mos because contractor takes on more work than team can handle. Many mistakes are due to lack of supervision and his staff does not maintain a clean worksite causing waste and lost materials. He does not have electrical or plumbing subcontractors. His pricing is not transparent and he uses change orders to increase his profit. He takes no responsibility and is difficult to work with. Have a detailed time schedule backed by a holdback from each payment that is released only on satisfactory completion."

"We recently had an “old school” original 1970’s Cape Cod kitchen fully remodeled including adding a slider. Richard did a great job from planning and design (shout out to Hanna on this), to demo, to install, to finish work. Richard was on time, reliable, and not your typical Cape contractor. Super clean at all times and was able to work with us on various hiccups/unexpected stuff along the way. He explained options and the pros and cons of each possible choice. He never upcharged us (unless we asked for something) and was exactly on budget. Very happy with his work and would definitely recommend. We will likely call on him again for our next project."

"Highly recommended!! Liam did a wonderful job with my closer repair. The room was gutted to the studs from a water leak and Liam put it back together beautifully. I’m very happy with his craftsmanship and excellent work. He was courteous, professional, and very skilled. I’d highly recommend his services!"

FAQs for basement remodeling projects in Harwich, MA

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.
