"Wade removed my crumbling aggregate porch steps and replaced them with a wood set. I'm very pleased. His communication and promptness were great. He told me exactly what he planned to do and gave me a quote right away. Based on my experience, I'd definitely recommend Hansen Building & Renovations. "

"Salesman that we were to replace dry wall. Later learned we were to have it removed. Attempts to reach supervisors and owners resulted in zero until time to do installation. Gave $1300+ down. Note: this went to the salesman, not to MABS. Then salesman stated $12,000 more if MABS removed the dry wall. Paid salesman and his friend to remove it but didn't do all of it! Sent certified letters to Cedar Rapids address after we got no verbal responses to phone calls. Later learned they receive no mail there, only in Davenport. Were to have GFI outlet placed at far end of basement. 3 electricians said not possible. Also discharge was to be underground to rear of yard which we thought meant to back! House sits on clay. Was to discharge under ground out 10 feet from house. Canceled installation and have found that other basement waterproofing companies do not require 2.5 feet of dry wall removed: only baseboard. Cost was same as MABS. Now we must pay to have drywall installed after the waterproofing is completed."

FAQs for basement remodeling projects in New Windsor, 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.
