"I couldn’t be happier with the work done on my basement remodel. The quality of craftsmanship, attention to detail, and professionalism were outstanding from start to finish. Everything was completed on time and exactly as discussed. Even came back fix a sticking door and made sure everything was perfect."

"<br />  She did a great job of incorporating what our kitchen cabinet supplier/designer suggested.   Many of the iterations were handled via e-mail that were both time and cost effective for both of us .  As I stated, after the positive kitchen experience we then hired her for a second floor dormer addition including a dormer with a full bathroom.Although we had a very small footprint for the bathroom, Kristi came up with a cleaver design to get a full bath that incorporated a large shower over the window - she gave us great  advice that a large ? killer? shower would be great for resale.  (so much better than the corner shower I envisioned).  Kiristi did great on meeting all our turn around requests which kept our project on schedule."

"I couldn&#39;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 My basement was dark, outdated, and underutilized, but now it?s a bright, beautiful space that feels like a whole new level of my home.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&#39;ve completely transformed my home, and its so nice to spend time in our new gorgeous space!"

"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. "

"Dave, along with Granite Plus was hired to renovate our kitchen counter. Dave's job was to cut down the counter from bar height to counter height. Expertise in carpentry, drywalling, painting, plumbing and electrical was necessary. Dave coordinated these specialties along with the Granite Plus folks such that the entire project was completed on schedule and without issues. While dust was a given during the project, Dave sealed off the kitchen in a floor to ceiling plastic room and utilized an air purifier to nearly eliminate the spread of dust. Each night his crew "Swiffered" the kitchen clean. Our old sink & plumbing was functional but for only one day! Then, promptly after Granite Plus installed the new quartz countertop, Dave's guys returned to install the new sink, etc. All was seamless! Dave and his crew did such an impressive job, I hired him thereafter to change out 2 ceiling fans, 3 ceiling lights and retrofit the kitchen cabinet drawers & doors with soft closure hardware. Upcoming, Dave has been hired again to perform additional plumbing and electrical work in our condo. You can depend on Dave!"

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.
