"I can’t say enough good things about Chris and his team at Dynamic Basements Plus. From start to finish, they were always on time, highly professional, and excellent communicators—keeping me informed at every stage of the project. They transformed my unfinished basement into a beautiful, versatile living space, adding nearly 600 square feet to my home. Every aspect of the work was top-notch—from framing, plumbing, and electrical to painting and final finishes. The quality of craftsmanship truly stands out. Chris and his team were also incredibly innovative, offering great ideas to maximize the space while using high-quality materials specifically suited for a basement environment. The result exceeded my expectations in both function and design. I highly recommend Chris and Dynamic Basements Plus to anyone looking for superior workmanship, thoughtful design, and a team you can trust."

Amazing communication, stayed on budget, worked very well with us and the work was done quickly and exactly as described. Any issues were immediately dealt with. 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."

FAQs for basement remodeling projects in Old Lyme, 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.
