"When I called Craftsman Builders, I asked for an estimate on the bathroom. I discussed the finacial situation to Larry. After he inspected the bathroom, he called me back promptly on June 23 and I agreed on the price on $2,900. He started the job June 28 and finished July 6. The total cost ended at $3090. The plumber ran into some unexpected problems so I paid to have walls painted. Craftsman Builders did a beautiful job. Very promt, particular with his work, and respectful. Cleaned up after each day's work. I felt very comfortable with his crew. Can't say enough about how proud I am about the new bathroom. Beautiful job."

"I recently had Mighty Basement and Bath finish my basement and build a new bathroom, and I couldn't be happier with the results. They did a fantastic job, kept the project on schedule, and stayed right within my budget. The final space looks absolutely amazing! Highly recommend Scot and his team for any remodeling needs."

FAQs for basement remodeling projects in Wilmington, IL

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.
