"Exceptional service, very professional, very knowledgeable and honest from the initial contact to finishing the job! Very impressed with this company! My basement now looks great as they sealed the cracks to reduce the radon levels and lined the walls."

"esInitially it started out well but as is typical in this industry, things start to fall off.  He is able to do most phases of construction but prefers trimwork.  The scope of work that we had didn't fit where he wanted to be.  If it was a single job that he was being hired for, I think he would be good.  He did good work but we do a lot of custom stuff and that throws our subs off sometimes.  Super nice guy and I felt that he was trustworthy. <br />"

"Gary showed up when he said he would and worked very hard each day until the job was finished as quoted. All scrap material was taken away each day and site was left cleaner than when he arrived.  This house was a Victorian built in 1929 and he built the porch as if it looked when built and we could not be more pleased.  Work was outstanding and we recommend him to everyone who ask who did the work. <br />"

FAQs for basement remodeling projects in Thomson, 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.
