"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."

"The JK Complete Remodeling team is very talented. They helped me design the basement remodel (about 1000 sq feet) with a bathroom, bedroom, kitchen/bar, tv area, storage, coat closet and kids area including building it all out. They walked us through the different steps of the build out and made wonderful suggestions on what would look best or makes the most sense in layout, electrical switches/outlets, etc. Their carpentry, tiling and stone work is impressive as you can see from the pictures. They built the shelves and wine rack in the bar area, built the frame around the chalkboard paint in the kids area, built out a closet into our garage space. I would highly recommend this professional team."

"Christopher Baugh was wonderful to work with and worthy of our trust, both practically and creatively. He was ALWAYS responsive to our inquiries, ideas, concerns, etc. Equally important, the crews who spent so much time in our home during the kitchen renovation were pleasant, kind, and generally arrived on time. They took any questions that we might arise to Christopher, receiving answers in a timely manner. During a reno that is important, since they are present for hours every day. Our expected timeline for the renovation was well met and we were always comfortable - as much as possible during a kitchen remodel! - feeling heard and respected. No question was too dumb or redundant and we really appreciated that. As a result we have a beautiful custom kitchen, with cabinets handcrafted by Christopher and I think everyone associated should be proud of their hard work. We can't wait to show it off!"

FAQs for basement remodeling projects in Oswego, 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.
