"Nixon and his worker worked straight for 5 hours moving 4 rooms of very difficult and heavy furniture. They then went on to repair a desk and hang a very heavy old mirror. They were wonderful. They are planning on returning in the spring to do some outside garden and yard work. I now know who to call when I need anything and everything done in my house."

"C&C completely gutted and renovated our hall bath and partially redid the master bath. The work included repair to downstairs ceilings, painting, as well as replacement of numerous doors, and replacing hardware in other rooms. I cannot say enough good things about this company and crew. They did impeccable work, were patient and helpful when materials delivered incorrectly and immediately helped us figure out solutions that turned out better than our original plans. They were respectful in our home, did amazing daily cleanup and the end result exceeded our expectations, which is not easy to do. Their estimate was spot on, no up-charging or hidden costs and the job was finished two days earlier than estimated. C&C will be our first choice for all our future renovation plans!"

FAQs for basement remodeling projects in Newtown, 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.
