"I hired GR General Contracting to remodel my basement. Every aspect of the project was excellent. My remodeled basement is beautiful. I would definitely hire again. Gordon communicated regularly about the project schedule and kept me up to date every step of the way. The crew were outstanding and it was a pleasure to have them working in my my home. At the end of every day I received a walk through of the progress and an overview of the next days work. I am thoroughly impressed with my experience working with GR General Contracting."

"Gordon’s team did a really good job remodeling my bathroom and my unfinished basement. Their new drywall & flooring installation work great and they did a good job with the plumbing & electrical adjustments I needed done. They cleaned up the mess they made daily and tried to keep the rest of the house clean and dust free. Total cost for both basement & bathroom remodel was $23900. There were some additional remodeling costs that I didn’t budget for initially but Gordon was willing to work with me on making payments for the additional features that were added to the remodel. Overall they are a good company and I’m happy with the work they did."

"It was great! Nick does a lot of big projects, and our job was a smaller one, so we had to work around other schedules from time to time, and Nick is also not big on tons of email or paperwork which was mostly fine, but there were a few minor miscommunications and moments where we wanted more information, but all was quickly resolved to our satisfaction. Regarding the actual work, every contractor was very professional, and Nick checked on and followed up with all of them. The work was all done very well, and several months later we have no issues or concerns. Everything looks so great! We had a water issue in our basement and no longer have to worry about that. The new bathroom is our favorite part. It feels spacious because of the layout and design choices Nick made, but actually it's a really small footprint which is perfect!"

"I couldn't be happier with the basement remodeling service. The crew came early and was very professional, timely, and exceeded all of my expectations. My basement was dark, outdated, and underutilized, but now it?s a bright, beautiful space that feels like a whole new level of my home. They make custom built-ins to modern lighting. The work process was amazing and thorough, and the materials used are high quality. The attention to detail is incredible, every corner of the room looks perfect. Reasonable estimate and they've completely transformed my home, and its so nice to spend time in our new gorgeous space!"

FAQs for basement remodeling projects in Waukesha, 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.
