"Workers on time. Did not finish first day due to rain second day they did not arrive until late after another job to seamed hurried. They were careful not to cause a mass inside but I had a day's cleanup in the basement. Works pleasant."

"The work was done properly and when some additional jobs were added, Mr Grant went out of his way to get subcontractor's in to fix the added jobs promptly. I was very happy with the results and would recommend Steven Grant Construction to anyone who needed a prompt quote and a properly done job. He took the extra steps to finish my job within the quote so I stayed on budget."

"The guy that they sent off to do the work was not very knowledgeable. I had the work done before so I knew what was supposed to be done. I actually told him how to do the baseline. It ended up coming out alright. I have another company do it a little cheaper but they don't do our area anymore. They're on time in everything. I would probably not use them in the future."

"Sam worked in some of the worst weather of the winter and did everything it took to get the building up.  The scope of the project increased from the time he quoted but he was fair in his requests for additional costs. <br />"

FAQs for basement remodeling projects in Cornell, 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.
