"Ceaser and his brother were amazing! Another flooring vendor dropped the ball, and they were able to step in and get the job done in just three days - quote, sample and installation. They were very professional, responsive and kept us updated on the progress and status of the job. They jumped through hoops to make this happen for my parents, and we all couldn't be happier. Ceaser even went out of his way to my parents' current home to personally thank them. He even climbed up on the tractor to shake my dad's hand when the job was complete. Even though they are in northern Illinois, I know I will be recommending them to anyone who has a remodeling or flooring job. Thank you!"

"Jason and his team just finished our house remodel project. It began late last year with a remodel of three bedrooms and a half bath. When they were done, we had no choice but make the rest of the house look as good as the bedrooms. So we almost immediately had Property Revision begin the complete remodel of our kitchen, living room and family room. This included a complete demo, removal of a lid bearing wall, and multiple layers of old flooring. They were originally scheduled for 8-10 weeks and completed the entire project in 6 and a half weeks. They were efficient and very knowledgeable about their trades. And their craftsmanship was some of the beat I have ever seen! To be clear, there was no surface in our entire house that they did not touch over a 4 month period of time. Would gladly work with them again and HIGHLY recommend them to anyone look for a remodeling of their home. We have recommended them to several of our neighbors already!!!"

"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 My basement was dark, outdated, and underutilized, but now it?s a bright, beautiful space that feels like a whole new level of my home.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!"

"Moore Custom Solutions did a fantastic job remodeling our bathroom. They transformed our old bathroom into a beautiful space. Shawn was easy to work with on the project. He did a great job of keeping us informed of all of the steps along the way. The workers were all very professional and courteous. We felt comfortable having them in our home. We get many compliments on our beautiful bathroom. I strongly recommend them for any remodeling needs."

FAQs for basement remodeling projects in New Berlin, 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.
