We're known for our quality work and the integrity of our business. We look forward to building long-term relationships with our clients, and guarantee your satisfaction.

"Hi. I am a baby boomer so I wanted to direct this towards others my age. I want to outline how wonderful my experience was with Usin from Custom Build and Remodeling llc. He was prompt and professional. Our first conversation was Sunday evening and he and four other employees were ripping out my bathroom completely on Wednesday morning. They showed up at 8:00 sharp every morning and worked till 4:00 each day. We had some extra issues in the 65-year-old house that Usin handled professionally with complete communication. They cleaned up thoroughly after each day and there was not one time within this entire project that I felt insecure. That’s a huge bonus! I am thrilled with the way the bathroom came out. A leaking vent pipe and wiring concerns led to problems above the bathroom in the attic. I was completely aware that my roof was shot so we agreed it should be done now. Roof, gutters and a house paint all done within the same timeframe. Highly recommend!! Serious professionals!!"

FAQs for basement remodeling projects in Trumbull, 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.
