"Tom and team did a basement remodel for me about 13 years ago, including adding a bathroom. Subsequent projects were window replacement for the entire house, and new roof/front porch. We received numerous compliments about the roof and front porch as it improved the entire look of the house from the street. He also replaced my concrete driveway to make it double wide. The most recent job was updating the columns wrapped around the porch. They were wrapped in aluminum which looked great but seemed like squirrels like to chew on them. Went with a different material this time around."

"My bathroom looks exactly how I imagined it would. STL Build Pro did an excellent job. My bathroom was very outdated, it was totally gutted down to the studs and remodeled to a more modern bathroom. The workers were very professional - even when I would make surprise visits on my lunch hour just to see what was going on. They were always working and took time out to explain to me what was going on and where they were with the project. With any project, there were a few minor issues but nothing that took a lot of time to fix. I highly recommend Jason, Tony and his crew."

"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."

FAQs for basement remodel projects in Affton, MO

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end. 

For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
