Customers say: Quick response

"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!"

"Overall good job with finishing my basement. i really like my basement overall after i installed carpet from Home Depot and home-theater system from Best Buy. i really appreciated them picking up the selections for the basement bathroom from Home Depot. Things that could have been done better: * I had to replace the closet fixtures, probably because they were fixed on the dry wall. * would have been better if i had choice with the shower inside the basement bathroom."

"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!"

"Ron was great to work with. He was very friendly and accommodating. He and his workers always cleaned up after themselves. His pricing was very reasonable. When sections for our fence were delivered, Ron was not impressed with the quality so he got them returned, ordered the necessary wood and together with his team built the fence from scratch! It looks great and we could not be happier. I can't wait to call on Ron and his crew for our next project. <br />"

"Things went very well. The four-person crew was prompt, professional and and efficient. The foreman described what was going to happen and how. The concrete walkway, front step and driveway sections that had settled over time were gently lifted and leveled using a polymer foam. After the work, all of the driveway section seams were level and smooth. Very few traces of the work were left behind. We would highly recommend Badger Basement Systems."

FAQs for basement remodeling projects in Janesville, 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.
