"I met Craig at my home to give me an estimate for interior walls in my garage and then added interior to stairwell to basement then added removing a window and plaster hole. Every time I added something I was greeted with “ok we can do that” and they did better than I had asked for. Very happy with all the work done."

"I've contracted Midwest Remodeling to build out a new finished room in my basement and I have only been impressed with their knowledge, professionalism, attention to detail, communication and cost. They work with a well-known and qualified electrician at Schneider Electric and both parties are responsive and understanding to project changes and additional requests. The Midwest Remodeling team can complete most any contracting / handyman project that you can think of and I highly recommend that you contact their team for your next project."

Customers say: Quick response

"Gerry is an exceptional contractor and exceptional human being. As newer homeowners and inexperienced handy persons, Gerry went out of his way to explain processes and provide thoughtful insight into the work being completed. He has a great relationship with his subcontractors and that was prominent when issues arose as they were quickly fixed. We provided Gerry with a professional drawing of the basement and he provided his thoughts and made quality improvements without changing the overall layout. Our basement was built during the COVID pandemic and Gerry stored masks and disinfectant directly outside our front door so all parties involved felt comfortable and safe. During the initial quote was honest about the supply chain disruption and the potential for delay in supplies. Overall, it was fantastic to have an individual flexible and accommodating to the changing environment. The quality of finished basement exceeded our expectations by far. We were skeptical of hiring a general contractor at first, but have no questions since hiring Gerry. If we were to build a home or have another significant remodel, we would hire Gerry again in a heartbeat."

"It went wonderfully!They installed a new threshold, all new trim around the door inside and even hauled away our old door. Everything was done so professionally and beautifully. There wasn't a speck of dust left behind after they did the installation. Just spotless! So well done and beautiful. The door is perfect! <br /> <br /> They were great consultants before the install as well - telling us everything we needed to purchase so I had no doubt in my mind that we were buying the exact things we needed. <br /> <br /> When we get our windows replaced, we will be calling them again!"

FAQs for basement remodeling projects in Oshkosh, WI

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.
