"We had a great experience working with Top Bros construction and remodeling. They fully removed our tile and wood flooring and installed LVP that we had provided. They also installed new trim and baseboards throughout, which look great. They were timely and efficient. We are very happy with the outcome!"

"Granzow Home Inprovement was amazing, from the initial meeting, to questions or concerns we had, before, during, and after the work was performed. We were pleasantly surprised mostly by the care and concern Rick and Bob took regarding their customer, which is rare in many businesses. This was our first home remodel project, we learned a lot from it, and we love our basement! Keep up the excellent service!"

"These guys were great! I hired them to install a laminate floor & baseboards in my lower level & they completed it quickly & professionally! I then used them to install a vanity/sink & toilet. Although the my bathroom was not plumbed for this, they were knowledgeable enough to get it done! I will continue to use them for all my handyman needs. Just a couple of nice guys with great talent!"

"Bob and Rick did an incredible job finishing our basement. They were willing and able to accommodate all of our requests and maintained open lines of communication throughout the entirety of the project. Rick responded to all communications very quickly and was always willing to field a call with any questions. From the start of the bidding process through the end of construction, Bob and Rick were always professional and provided guidance and transparency at every step while still allowing us some creative flexibility during the design process. We are consistently getting compliments on the superb craftsmanship of our basement. If you are looking for a professional team, clear and timely communication, and magnificent quality of work, I highly recommend Rick and Bob at Granzow Home Improvements."

"I contacted John on a Saturday, and he was able to come out the next day on Sunday morning. I had purchased the doors, and he ripped out the old doors and replaced with new ones. He took care of the casing as well. I was pleased with the work, the price, and John's just easy to work with as well. Very nice gentleman."

"Joe and his team were the first to respond after the Milwaukee floods happened in August 2025. Him and his team went above and beyond to clear out all of the debris in the basement, fully cleaned the basement, and applied mold remediation to the wooden beams. They also fully rebuilt our stairs and removed and replaced our egress window. Thank you so much Joe and team!"

FAQs for basement remodeling projects in Jefferson, 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.
