"
They did an excellent job of everything. Owner/architect, Kristi Minser is very willing to work with clients' own ideas and she is flexible with changes and modifications. The crew has a lot of integrity when it comes to doing things right and providing the best aesthetic outcome. I am so pleased with the care the head carpenter put into this job, especially a wall of custom built-in bookshelves surrounding our bed. They are stunning!
While there were some delays in progress during this project, I would highly recommend Amethyst to anyone looking for a remodeling contractor.  Kristi only hires good people who care about what they do.  We also felt the services provided were very fairly priced."

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."

"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!"

"We were very happy with GR Contracting! They did a fantastic job on finishing our basement. Gordon and his crews were quick from the framing to the finished project. They were meticulous in attention to detail and made some changes that we requested after the project started. Communication was great and the project was finished on time and on budget. I would highly recommend GR Contracting for a basement finishing project. Our basement rooms are beautiful and we are completely satisfied."

"These guys were great! I hired them to install a laminate floor & baseboards in my lower level & they completed it quickly & professionally! I then used them to install a vanity/sink & toilet. Although the my bathroom was not plumbed for this, they were knowledgeable enough to get it done! I will continue to use them for all my handyman needs. Just a couple of nice guys with great talent!"

"We had a very positive experience working with the team at Redefined Remodel + Construction LLC. When we first contacted Mr. Meldman about our sad-looking basement, he replied quickly and came to the house for a walk-through and discussion about project ideas. Within a week he presented a precise and detailed contract that met our needs. And throughout the project, Mr. Meldman promptly responded to all our communications and did more than just answer our questions; he explained those answers. We felt confident with the skilled workers who entered our home and were always treated courteously and with respect. The results of our project are exactly as discussed and look great! We would definitely contact Redefined Remodel + Construction LLC again for future projects, and recommend their services."

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.
