"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."

"I consider myself a little more than a novice on general construction when it comes to studding and drywall. I am also a bit of a perfectionist. I needed support to help me studd my unfinished 1700 square foot basement in a new construction home. After calling over a dozen contractors who would either charge me ridiculous prices or tell me that they only do projects like this from start to finish, I met Jordan from JWC and he agreed to take on my project for a reasonable price. I was a little apprehensive at first because his was a young business. Folks, let me tell you. Jordan and his crew came in and absolutely KILLED IT! After three days of back breaking work I was left with a perfectly square and plum studded basement. Throughout the job, Jordan and his team were friendly and courteous to my family and I. More importantly they tackled the work with the focus and know how of a 20 year business. I was floored by their efficiency and ability to navigate the challenging areas like the knee wall I requested along the back wall. I could not be happier with the professionalism and work that Jordan with JWC provided. All of which was provided at a reasonable and honest price. Thanks again JWC Recommend 100 out of 100!!"

"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."

"Dave A, of "Basement REPAIR SPECIALISTS", is someone you should have on speed dial. Dave showed up and thoroughly inspected the areas of concern. After examining the basement area he said he would like to look at the outside of the home. He took his time, commenting on yard drainage grade, gutters, and roof pitch. He said, "he would love to take the Job but he thought we should first take a much cheaper approach to repair our problem". Dave obviously is a man of integrity. We decided to take his recommendations. If we still have continued problems, Dave will be our contractor of choice. It's really nice to do business with a thorough and honest man."

FAQs for basement remodeling projects in Sun Prairie, 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.
