"Jason and his team were great! Good communication throughout the entire project, and finished under the time line given. They remodeled my basement and added a bathroom. All of the sub-contractors were very professional and very accommodating to any special requests I had. All in all a great experience!"

"RNR was hired to take on an extensive project that involved remodeling three apartment units in two separate residential homes. They were quick to respond to provide a free quote, honest about their capabilities for the services needed, and provided a fair price in a timely manner. On top of being incredibly personable and easy to work with, they take pride in their work, always keep a clean workspace, and absolutely deliver on whatever is asked of them (which in this case the list kept growing). They completely transformed the three apartments that they remodeled - from installing cabinets, countertops, toilets, showers, doors, light fixtures, flooring, windows, interior/exterior painting - to fixing unstable decks and chimneys, they can do it all! You definitely won't regret giving them a call!"

"Joe Timm did an extensive remodel of our 1965 ranch fixer-upper, that included kitchen, 2 baths, great room, 1 bedroom, and den. He was professional and thorough. His price quotes were on-target and reasonable. He was reliable: he called and visited when he said he would. We'll use him again for our unfinished basement. We highly recommend Joe and his work. "

"The Project Manager, Bob Reber, was extremely helpful. He really knows a lot about basement water solutions. He is also very polite and is welcome back in our home any time! He quickly developed a detailed recommendation for a solution to the problem we were experiencing. Even better was the fact that he was willing to reduce the required work as we discovered additional information about the details of our situation. If we ever need any additional help with our basement, Bob is the only person I will call! Thanks for all your help!"

"Jeff and his crew were absolutely amazing! In just over 3 months time, he turned our open/empty basement into something that exceeded our expectations. His communication was impeccable throughout the whole process. He was always kind and patient with us. Jeff put any and all of our doubts at ease with his craftsmanship and expertise. Most importantly, he stayed within our budget! I'd recommend Kettle Moraine Kitchen and Bath to everyone I know. We will use him again in the future and suggest that anyone reading my review does the same. He restored my faith in contractors because he's honest and hardworking."

FAQs for basement remodeling projects in Grafton, 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.
