"We hired Excellent Construction after seeing the basement remodeling work they did for our son. Their work sold us. In addition to kitchen work, we had work done in a bathroom and refaced our fireplace. Once again, they demonstrated pride in their work, attention to detail and great communication. They showed up on time, and left the work site spotless. We are very happy with the quality of work and will definitely keep their contact info for future work. Highly recommend."

"Mighty basement did a great job on my basement remodel. I had company coming in July and Scot Coleman made sure the remodel was completed by my target date. He was supervising the job and did a tremendous job. Scot was very professional but at the same time was attentive to what I wanted. He was great to work with. I would highly recommend Might Basements and bath."

Customers say: Quality work

"We trust Jeff with our major projects. Last year he remodeled our two bathrooms. This went so well that we decided to go ahead and update our kitchen. Jeff gave us ideas about the remodel and also recommended an excellent cabinet company. The project was seamless. All of the work was completed within a month and the results are stunning. We're looking around the house for another project Jeff can help with. I'm convinced that there's nothing he can't do."

"We had a month to build an apartment from scratch. Larry and his team did it, and we have gotten tons of compliments on it. I could never have imagined we’d go from an overstuffed basement to a beautiful, cozy home in so little time. The pictures don’t do it justice"

"I can't say enough about these guys and wish I hadn't lost their contact information for a time. About 8 years ago, I had Sal and his guys do the finish work on my basement drywall that I hung. They also hung some drywall in the stairway going to the basement. Initially, they hung the soffit incorrectly but it was just a communication issue. I called Sal, he took a look and they came back and re-did it right away without hesitation. Their work has lasted this long without any problems. I started another remodeling project in my family room and needed a ceiling hung and finished, along with finishing some walls I had hung. Unfortunately, I had lost the contact information for Sal so I had to find another company. Long story short, this other company did an absolutely terrible job (Do not use NoticeTMA LLC for any drywall!). The family room adjoins the kitchen, and I had taken a wall down between them. I decided to carry the remodel over into the kitchen, and when it was time to hang the ceiling in the kitchen, I had found the old invoice from High Quality Painting and decided to see if they were still around. I am glad I did. Sal's son's came out to give me an estimate on my kitchen ceiling and also to repair the bad work in my family room. I decided to remove the new ceiling in the family room and have them do the whole thing. Their price was very competitive and everything turned out great. The old job didn't last 4 days without cracking. Luis' job has been up for a month now and there are no issues (and I am a very picky customer). I would highly recommend them for drywall hanging, finishing and repair."

"Kris and his assistant did a great job for remodeling two full bathroom for my townhouse.  They were punctual.  We negotiated the price pretty well since the original quote I thought it was too high.  Overall, I highly recommend them for any remodel or any home improvement projects."

FAQs for basement remodeling projects in Downers Grove, 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.
