"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."

"We had Shire Group work on a remodel of a new office for us. They removed walls, framed in new doorways, and, in an ample space, created five new offices from the ground up. They asked questions that we never would have thought of. After completing the project, many visitors asked about their work besides the new offices. This shows how detailed they were; people could not tell new trim from old trim, removed doorways, moved light switches, and turned an old mailroom into extra space in our kitchen."

"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."

"Truly a full-service company - we just had our 6th project completed by Closets by Design last week. Our installer, Jake, did a fantastic job, taking his time to make cut outs for the outlets. When the project was completed, he made a recommendation that we have a trim piece along the desk. Our house is over 100 years old and the floors and walls are uneven (especially in the corner where we had this desk placed). He discussed options, placed the order, and had another tech come out today (the next business day) to install the trim piece. It was the perfect finishing touch and we could not be happier with how this project turned out. We had intiially ordered a desk from a furniture company, but the shelf and drawer sizes were all wrong and some of the drawers didn't open all the way. Closets by Design gave us the option to purchase a truly custom desk."

FAQs for basement remodeling projects in Beaver Dam, 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.
