"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."

"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."

Customers say: Quality work

"I think it's a testament to a company when you have such a great experience that you go back to them again for a second project. We worked with Bill and his team on a basement bathroom remodel 3 years ago and loved it. When it was time to finish the basement remodel and redo the flooring, windows and some lighting in the adjacent finished portion of the basement, I knew I wanted to work with him again. Bill is very easy going, but extremely knowledgable. He helped us through some material selection, provided sound advice on options and saw the project through to completion. I've personally recommended him to friends, and would absolutely work with him again on any other remodeling projects that come up at our house. Five stars, full stop."

"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. "

"Big Dave was a pleasure to work with. In the middle of a bath and kitchen remodel my husband sustained a severe back injury. Big Dave and his guys stepped in to complete the work. They didn't do anything we did not ask for, gave good estimates when we asked for extra things not included in our original contract and made our experience a great one. They created a new wall in the kitchen to hide the tankless water heater, painted it, installed cabinets and a sink. In the bathroom they placed the tub surround, painted and finished installing the vanity. Then we asked them to replace the drop ceiling in a hallway, it was quickly taken care of. We will definitely use them again in the future."

FAQs for basement remodeling projects in Wauwatosa, 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.
