"We had a lovely experience working with Excellent Remodelind. Jolanta was always responsive and worked around our schedules throughout the whole process. Wojtek thought of everything along the way to ensure we got the basement we wanted. His work ethic and professionalism was second to none. We could not recommend them enough."

"Joe and his crew did a great job on repairing and painting my Yard Barn. They removed my rotted doors. Completed rebuilt the frame and created new doors which are much sturdier. They replaced a large portion of the back of the Yard Barn which was in need of repair and put a new one in it's place. They completely painted my entire Yard Barn for me and put new strips on my siding that needed replacement. My yard Barn looks even better than it did when it was first built. Joe is very personable and easy to work with as well. Highly recommend them !!"

"We chose Design One to remodel our small galley kitchen after meeting with them and seeing their reviews. Initially, they presented as organized and professional. I wish we had asked more questions upfront. The quality of work was poor, especially drywall and basic carpentry skills. The average time spent was 10 hours/week. When they started work, all needed materials were in, yet it took over 7 weeks to complete. Requests for a schedule were evaded. There is no crew it is Rich, and occasionally Linda to assist. Very poor time management at the customer expense. Their lack of transparency regarding certain paperwork was troubling. What should have been a rewarding project became a large disappointment."

"Our experience with Matrix Basements could not have been any better! They were an amazing company to work with and the end product was better than we imagined. I fully believe this has so much to do with the fact that Matrix is well organized and professional every step of the way. Every single person we worked with throughout the process was extremely friendly and very knowledgeable in providing us input to make our basement remodel come to life. We lucked out with an amazing field manager, Jim Thurek, who guided us every step of the way. He was very attentive to our needs and questions, which was always reflected in his professional and speedy response time. The management skills of this company is definitely unrivaled and I would recommend them to anyone who is looking for a reliable contractor to finish/remodel their basement."

"The quality of work is fantastic, and Marek is the best project manager you could ask for. The reason I removed one star is because I believe the quoted contract price, specifically for allowances, can improve. You should expect to add a minimum of $20,000 to your contract price. I also recommend referring to your contract throughout to ensure you aren’t getting an extra charge for something that should be included. Like I said, the quality of work is fantastic, but the up front pricing can improve."

FAQs for basement remodeling projects in Saint Charles, 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.
