Clayton has one of the oldest residential housing stocks in the St. Louis metro — a substantial share of homes were built before 1940, sitting on stone or coursed-block foundations that were never built with modern vapor barriers. Mold Solutions has remediated these century-old basements, Tudor revivals, and DeMun four-families for years. We know how to handle older Clayton housing with the care it deserves while still getting moisture and mold out of the building envelope for good.
Clayton’s residential character is dominated by early-20th-century brick and stucco homes — Tudor Revival, Colonial Revival, Arts and Crafts — concentrated in Old Town, DeMun, Hi-Pointe, Brentmoor Park, and Carrswold. Most sit on full unfinished basements with original stone or coursed-block foundations, cast-iron drain stacks, and below-grade coal chutes that have been converted to storage. These are beautiful homes — and they hold moisture in ways that modern poured-wall basements never will.
Geographically, Clayton sits on the Mid-County limestone ridge. There’s no major river floodplain to worry about; the water issue here is groundwater, stormwater, and aging sewer infrastructure. Deer Creek drains the southern edge of Clayton, and MSD Project Clear has been working through the Deer Creek watershed for years to address combined sewer overflow and undersized 1920s storm laterals. Until that work is complete, sanitary lateral backups during heavy storms remain a leading cause of finished-basement mold in 63105.
Newer construction in Clayton — the high-rise condos along Forsyth and Maryland — brings a different mold profile entirely: HVAC-driven humidity in interior units, condensation against cool concrete podium walls, and parking-deck moisture migration into ground-floor common areas. We treat both ends of the spectrum and have certified protocols for each.
Whatever brought you to this page — a smell in the basement, a stain on the ceiling, a recent water event, or a real-estate inspection that flagged something — here’s what we do for Clayton homeowners.
Visual inspection, infrared moisture imaging, surface sampling, and third-party-lab air quality testing. We identify what species you’re dealing with, where it’s coming from, and how widespread it is — before any remediation begins.
Full IICRC-aligned remediation: containment of the affected area, HEPA filtration, removal of contaminated porous materials, antimicrobial treatment of remaining surfaces, and clearance air testing to confirm remediation success.
Specialized remediation for the three most common mold-impacted spaces in Clayton homes: attic sheathing blooms, finished and unfinished basement growth, and crawlspace vapor-barrier failures. Each requires its own containment and treatment approach.
Emergency water extraction, structural drying with daily moisture monitoring, and full restoration of finishes. Done right, water mitigation prevents the mold problem from happening in the first place — which is always cheaper than remediating after.
Across every St. Louis County ZIP we work in, the same five spots produce the majority of our mold-remediation calls. If you have a Clayton home, these are the places worth checking annually.
We work Clayton top to bottom — and we know each pocket of the city has a slightly different housing pattern and risk profile. Here’s what we see most often, by area:
Every Clayton mold project follows the same proven workflow. The order matters — skip the moisture diagnostic and you’ll be back in six months.
We come to your Clayton home, perform a full visual inspection, run infrared imaging to find hidden moisture, and confirm with moisture meters. If air quality testing is warranted, we collect samples for an accredited third-party lab.
Before we touch anything, we isolate the affected area with poly sheeting, negative-pressure HEPA filtration, and dedicated entry/exit airlocks. This keeps spores from spreading to clean parts of your home during the work.
Porous materials that can’t be salvaged — drywall, insulation, carpet pad — are removed and bagged inside the containment. Salvageable materials are HEPA-vacuumed and damp-wiped with EPA-registered antimicrobial products.
All remaining structural surfaces are treated with antimicrobial products selected for the specific substrate. Affected areas are dried below pre-loss moisture thresholds with monitoring data we share with you.
We perform clearance air-quality testing to confirm spore counts are at or below outdoor baseline. You receive a full report with all data and photos. We can coordinate with reconstruction trades or hand off to your contractor of choice.
Older Clayton homes deserve a contractor who treats them like the assets they are. We’ve remediated everything from a Tudor in Brentmoor Park to a 1920s DeMun four-family to a brand-new Forsyth condo, and our process protects what makes your home worth protecting.
Family-owned, certified, and about 15 minutes from your door. Same-day response for active water intrusion or major mold discoveries.
