"Kristi and her crew were a pleasure to work with. They were very creative in fitting a half bath into a small space in our old home — making it look great and as if it was always there. They were reliable and got the work done on schedule (and without extra charges). Plus they were considerate as they worked in our home."

"Meinen Homes is a great set of people to work with. They did everything they said they were going to do for the quote they provided, and they did excellent work. They always kept us informed of their progress, they asked questions all along the way to be sure they knew exactly what we wanted done, and all of their employees are friendly and easy to talk to. A true set of professionals. They were also quite accommodating and open to some extra work that made sense to do while they were here, and they always provided a fair and reasonable quote for all the work they did. We love the end result of their work, and highly recommend them!"

"I’ve used Core Vision for two projects (exterior shutter removal, front-door handle repair) and both had fantastic outcomes. He’s responsive, reliable, and transparent. Will hire again!"

"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. "

FAQs for basement remodeling projects in Thiensville, 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.
