"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."

"My whole world crumbled when my bathroom leaked water down my walls and out of my ceiling. I didn't know what to do. I'm a new home owner and have never processed a claim through my insurance. Wes showed up to my house in all the mess. He was there within an hour of the issue happening. Not only did he and his company take care of the damage, they took care of everything with the insurance company. I was out of my home for over three weeks. My animals were displaced and I had to leave my kitties locked in the basement. They went so far above and beyond, they even fed and watered my cats! It was a stressful situation, but they took so much pressure off of me by handling everything! When I was finally able to go back home, not only was the water damage gone, my house was sparkling clean from top to bottom on both floors of my house. My house hasn't been this clean ever! It's like I walked into a brand new home. They updated me everyday. I never had to reach out, because they were in constant communication. I am so blessed this company came in and saved the day. The work was phenomenal. You better believe I have them saved in my phone. I was assured they do all manner of work my home could possibly need. Next time I need help with ANYTHING, I'm calling Wes at Plow and Property Projects!"

"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

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.
