"We hired MH Construction for a kitchen renovation, and we are thrilled with their work! Mike and his team were excellent from start to finish. Mike kept in regular contact with us throughout the process, answering our questions and working out the design. He and his team were amazingly efficient, often getting more completed each day than we’d anticipated, and they were polite, professional, and always kept the work area clean and safe. They also went the extra mile and conscientiously fixed unexpected issues they found, including several smaller electrical and plumbing glitches. Best of all, we couldn’t be happier with the end product: our kitchen is beautiful and more functional than ever. We’ll recommend MH Construction to all of our friends, and we’d be delighted to hire them again in the future!"

"From the beginning of my project in January 2024, I have never regretted my decision to choose Ethos Building Group LLc. Jeh Johnson and his partner Tracy Herod have worked diligently to execute the itemized proposal that began this project to rehab, restore, and rebuild my home at 607 Wilmington ave. St. Louis MO 63111. An incredible number of tradesmen and tradeswomen have done their individual tasks all on a schedule professionally overseen by Jeh. These liscensed and masters of their trades worked alongside Jeh who if necessary stepped in and aided e these individuals. His overall expertise has brought my home to this point. One must keep in mind that a burnout like my home is an unusal job for Ethos Buildig Group LLc to accept. Yet at every stage my home has been given the same careful and thorough attention as their larger jobs. And despite some push back with my insurance company every thing has proceeded smoothly and orderly manner given the inevitable supply chain delays. Jeh Johnson is an affable young man who has facilitated all phases my prject and has even taken time to educate me on all the intricacies involved in a project such as mine. I cannot think of any single word to describe my experience with Ethos Building Group LLc but the forgoing will have to suffice. Thanks you for your kind attention. Stay safe and make a point of telling those who you find dear just what they mean to you."

Basement Remodel FAQs, answered by experts

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.
