"Randy and his team did a great job finishing our basement in a short time. Along with finishing the basement, they took care of moving a drainage hole to save some space, replacing old basement windows, setting up kitchenette and a full bath with good quality products and work. They made sure we were satisfied with every piece of work and to do that they go above and beyond. We felt reassured when Randy's son says 'no biggie' to make any changes as we wanted. He can custom build almost anything, my son & his friends loved the hideout they built understairs. Whole team handled all work with great care and made us feel comfortable with all construction work around our newborn baby home. We definitely recommend them to our friends & family."

"We were extremely pleased with the work they did when we had our master bathroom remodeled. The entire process was seamless from start to finish. They were so professional when they were in the house and kept the entire area contained. I always assumed a renovation would be stressful, but it was not at all. Picking out the materials and fixtures was even fun! The entire team was great and they were exactly on time to the week. They were very responsive to any questions. I highly recommend them, and hope to work with them again in the future."

"Matt arrived on time and was efficient at replacing floor tiles. Do you think customer service is gone, well so did we until Matt Hemingway came to replace three broken tiles. He finished in 90 minutes and that included going back to hardware store for a different color grout because he didn't like the way it looked. When done you could not tell the floor had been fixed. Excellent job. Highly recommend."

"We found Tom and his team to be very professional, timely and respectful. They provided us with a high quality of workmanship and we are very happy with the overall results in all 3 bathrooms. Tom is not only the owner, but is very hands-on. He provided us with some good ideas on products and when we had a bit of a problem with a vendor Tom was very helpful in getting the issue resolved. If we decide to do more updates, we will definitely call Terbrock Remodeling. M&K"

"We are absolutely thrilled with our kitchen remodel by STLBuildPro! From the initial communication and bid process, though project planning, demo, inspections, installation, etc. they were responsive, professional and extremely dependable. And since any major remodel project typically involves change orders, I’m happy to report that the changes to the initial bid were minimal and absolutely necessary to get to our final vision. We would without hesitation hire STLBuildPro again, and recommend them to everyone!"

"I could not be happier with the final product! The first pic is the old bathroom from the 60s when the house was built. The rest are the final rebuild and it looks great. I would highly recommend VMK Remodeling for any project that you might have. I am also going to get a bid on redoing the deck on the back of the house as Vince's company does decks as well! Thanks to his great crew as well, great people to work with."

FAQs for basement remodeling projects in Saint-Louis, MO

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.
