"We had been planning a basement remodel for almost ten years. Our basement was a large, cold, and dim space that, in our minds, was underutilized square footage in our 1950s ranch. After looking through past work and meeting Chris in person, we entrusted Dynamic Basements Plus to bring our dream basement plan to life. Chris and his crew worked with us throughout the process to make optimal design and layout decisions, make crucial choices for electrical and plumbing, navigate the inspections and give us as much basement as we could get for our budget. We were impressed with Chris's attention to detail and willingness to go above and beyond to make things right. While we did go a little over budget, the choices we made improved the original plan and were lifestyle design decisions. Basement remodels are no short-term project. Over the several months and different phases, Chris's crew was polite, on-time, and maintained a clean environment. My son even grew a fondness for Chris, giving him hugs when he'd arrive and missing him when the project was complete. We are thrilled with our new basement. We now have a warm, cozy, and well-lit place to work and relax and the kids have a space all their own to play. It's almost like having a new house. We enthusiastically recommend Dynamic Basements Plus."

"Chad and Joe at Whitcomb & Holmes were so great to work with!! We couldn’t recommend them highly enough if you’re looking for someone to remodel your space. From our first conversation with them, we knew that we could trust them to get the job done in our exact vision. They helped us to work within our budget and provided valuable insights and recommendations based on their experience. We’re thrilled with how it’s come out and won’t hesitate to use them for future home projects!"

"I’m very pleased with the service and work I received from Timber Wolf contractors and his crew. He contacted me and arranged a time to look at the work I needed done. He promptly sent me a quote. He set up a time between our schedules to build my spiral staircase and replace a window with a vent. He arrived on time and completed the job beyond my satisfacon. I was so pleased with the results and communication I received, that I hired them to come to my other home to install "Flooring for my sunroom, pantry and hallway. They also painted trim and upgraded my hardware on my kitchen cabinets. I felt very comfortable with Timber and left him a key so I could go to work. I highly recommend Timber Wolf contractors for your home projects, they are professional, polite and hardworking. Respectfully, A. Saint"

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.
