"Chris finished our 1,300 sq ft basement and the result is outstanding! The project included a bathroom, office, pantry/laundry room, playroom, and gym. We even had him build monkey bars and a rock wall in the play area, a real treat for our kids. He was all in on figuring it out and it came out great. The craftsmanship throughout is excellent, with nice molding details and a clean arch above the TV area. We spent a lot of time together on the design and scope up front, and he was great about accommodating changes as the project evolved. He uses Joist to track everything, so the total cost and every add-on were carefully documented from the start. He came in right at budget. Communication was a real strength. We always knew what was happening each week and who would be on-site. His subs were professional, easy to work with, and accommodating. He's already doing another house in our neighborhood, if you're considering him don't wait!"

Any questions were immediately answered. Would absolutely work with these guys again and would recommend them!"

"Timber and Megan are consummate professionals who are timely, hard working and detail oriented. I was very fortunate to have them realize a project that was centered around creating an in-law apartment in an existing space in my home for my father. They worked with me every step of the way which resulted in a collaborative design with a nautical theme. The end result is stunning and everyone who sees it wants to live in it! Thank you Timber and Megan for making my vision a reality."

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

FAQs for basement remodeling projects in Stonington, CT

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.
