"They did a wonderful job, from first contact to the last time they walked out of the house. I had them finish about 1/3 of my unfinished basement into a completely finished room. Jolanta was engaging, detailed and professional in the original visit to see the scope of what I wanted done. She asked good questions and provided some good suggestions. She had a quote back to me within a few days that was detailed and helped me understand exactly what I was paying for. The work crew were all polite, respectful of my family and of my house. They cleaned after themselves each day. The work took about two weeks to complete and it seemed that they stayed on task every hour of each day. They obviously, to my untrained eye, knew what they were doing and took pride in their work. The result is amazing and I am very happy! I HIGHLY recommend Excellent Remodeling! They truly are EXCELLENT!!!!"

"I’ve always wanted a second bathroom. I contacted JK Complete R&C. Jack came to my home and assessed the would be project. Jack gave me a reasonable price, start and proposed finish date. Then I met the crew John, Mike and Ziggy. We had a great relationship. Everything that was to be accomplished was explained to me on a daily bases. By the end of the project we had a bond and it felt like family. I also learned quite a bit in the process. I am total fascinated with my new bathroom. I have already recommended JK Complete to family members."

"We recently had our 1,400-square-foot basement finished, and we couldn’t be happier with the results. The project included two bedrooms, a full bathroom, and a versatile multi-purpose space with two kitchen cabinet areas—and everything was completed beautifully. From start to finish, Scot proved to be an outstanding project manager. Communication was consistent and clear throughout the entire process, which made a big difference in keeping everything on track and stress-free. He was also incredibly efficient, ensuring the project moved forward smoothly without sacrificing quality. His crew was a pleasure to work with—professional, respectful, and clearly skilled in their craft. The attention to detail and precision in their work really stood out, from the finishes to the overall layout and functionality of the space. We highly recommend him to anyone looking for a reliable, communicative, and detail-oriented contractor. Our basement turned out even better than we envisioned."

"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.
