Basement & Crawl Space Waterproofing

The environment in your crawl space is crucially important to the air quality of your home.

Blake was extremely knowledgeable about crawlspaces. He was professional and made me feel very confident in the decision I was making. He recommended what was going to be best for me instead of trying to “up sell or over sell”
I reached out online and promptly received a call back to come visit the property. My seller was not aware that she even had a partial crawlspace or that it had water issues. Blake came out, gave a very reasonable bid and got us on the work schedule to accommodate our quick closing which was able to close on time. I am a broker of Red Key Realty with 180 agents, I am very happy to recommend Blake House at Crawlspace Medic.
Blake was nice enough to come the same day we spoke to take a look at our issue. He was nice, precessional and explain to me in terms I could understand about the situation we had going on but what I really also appreciated about him was that, before he approached the door he let me know he was vaccinated but he would wear his mask if it made me feel comfortable. I really appreciate it that!! I am definitely hoping to use his service!
We are happy to recommend Blake’s services. He came out and gave us some valuable information about our house that no one else could provide.
Blake House did an excellent job and provided me with his findings and recommendations that I need to make the next step in our moisture corrections. Thank you Blake and we will be in touch soon for scheduling!

Our Services

Crawlspace Medic® offers three main types of crawl space solutions to families in and around St. Charles County: crawl space inspections, moisture remediation systems, and structural repairs.

Flooding, burst pipes, quickly melting snow, and severe weather can all cause water damage in your foundation–and you may not even realize the full extent of it. Keeping your crawl space or basement healthy is key to keeping the rest of your house healthy. 

Our team of crawl space experts in St. Louis is ready to conduct a thorough inspection so you can know exactly what the strengths and weaknesses of your foundation are and fix problems before they get out of hand.

Water damage or excess moisture in your crawl space or basement can lead to lasting damage in your house. Issues like dry rot, mold and mildew, high humidity indoors, and termites are all results of excess moisture in your foundation.

We’ll conduct a thorough inspection and give you a detailed plan to eliminate excess moisture in your home so you can remediate and prevent damage under your house.

Did you know that most structural damage in St. Louis houses starts in the crawl space or basement? Telltale signs include fogging windows, sagging floors, doors that stick, gaps around windows and doors, and cracks forming on interior walls. These issues are common in older homes, but they’re not safe.

Protect your home’s structural integrity and overall value by addressing these problems right away. Call us today to schedule your inspection.
