"My wife and I needed to finish our basement to accommodate our growing kids. We had an excellent experience with Everything Under The Roof. They really listened to what we wanted to build and everything was done well, on-time, and on-budget. One thing I particularly appreciated is that the owner was onsite doing the work, and not simply sending a team of workers. We'll definitely be using Everything Under The Roof for any future projects. "

"I recently hired Erick's Painting Services LLC for a full interior repaint of my home, and I can confidently say they are the best in the business. From the initial consultation to the final brushstroke, their professionalism, attention to detail, and customer service were truly outstanding. The team was punctual, respectful of my space, and meticulously clean — they took great care to protect my furniture and flooring and left no mess behind. The color consultation was incredibly helpful; their expert provided thoughtful suggestions that matched my style and lighting perfectly. The quality of the workmanship is second to none. Every line is crisp, every coat is even, and the finish looks like something out of a magazine. They used premium paints, and the results speak for themselves — my home feels completely transformed. What stood out the most was their communication and commitment to satisfaction. They checked in at every stage, welcomed feedback, and made sure I was 100% happy with the results before wrapping up. If you’re looking for a trustworthy, high-quality interior painting company, Erick's Painting Services LLC is the one to call. I couldn’t be happier with their work and will absolutely hire them again for future projects."

"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."

FAQs for basement remodeling projects in Cromwell, 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.
