Questions we hear from Edwardsville

What Edwardsville homeowners
ask us most.

Our 1890s LeClaire Historic District home has original plaster and a stone foundation. Basement water history. Where would mold most likely be?

Lower wall plaster, bottom plate of any framed walls in the basement, paper-faced insulation, and stored organic materials. Stone foundation itself does not host mold but materials touching it almost always do in a water-history home. We meter, inspect, and lab-test. S520 scope if confirmed. Old Edwardsville historic stock often has multiple generations of repair layered, so we sometimes find mold behind a 1970s paneling job over the original plaster. We document each finding for the carrier.

SIUE rental on our property has had moisture complaints. Tenant says smell, we say maintenance. How do we resolve?

Air sample and lab confirm. We sample the tenant’s space and an outdoor baseline, the lab report tells you objectively whether spore counts and species composition indicate active growth. If elevated, S520 scope applies and the landlord is responsible. If baseline-normal, the smell is something else, stored items, ventilation, or DIY cleaning products. Honest documentation protects both parties. Edwardsville rental disputes often hinge on whether testing was done by an independent lab. We use one.

Our clay sewer pipe cracked and backed up. Edwardsville municipal sewer. Will American Family cover it?

American Family covers sewer backup under the endorsement if you carry it. Same as Allstate and State Farm. The cause being a cracked clay lateral does not change coverage, the rider applies to backups regardless of why the line failed. We document the entry and damaged materials. The lateral repair itself is a plumber’s scope and not covered by the homeowner policy. If you do not have the rider, the cleanup is out of pocket. Pre-2000 Edwardsville homes commonly have these failures, worth carrying the endorsement.

Why these questions in Edwardsville.

Mold remediation in Edwardsville splits between the historic core, where 1900s brick foundations and plaster walls hide chronic seepage, and the newer subdivisions, where finished-basement leaks and slow drips from PEX fittings hide loss for months. SIUE rental stock tends to underreport mold, which adds work when properties turn over. We work under IICRC S520 with full containment, HEPA-filtered negative air, and third-party lab clearance when the file requires defensibility. Cracked clay sewer laterals from the pre-2000 stock introduce Category 3 water during backup events, which drives mold scope upward. The Montclaire and Goshen Road corridor homes share similar profiles, and protocols are built on readings and lab results with clearance documentation owners can keep on file for resale, real estate, or insurance disputes. Owners get a written remediation protocol they can hand to a buyer or adjuster without translation.

How mold remediation actually runs here.

Mold in Edwardsville concentrates in different places by housing era. Historic LeClaire stock has hidden growth behind plaster and along stone foundation walls. SIUE-era homes show the standard finished-basement pattern with growth behind 1970s-80s rec-room framing. Newer subdivisions on Goshen and Governors’ Parkway have growth behind modern finished-basement framing fed by saturated clay backfill against poorly-compacted foundations. SIUE rental stock tends to underreport mold given the transient occupancy, and properties acquired post-rental period often surface contamination history during the assessment. Our S520 protocol uses third-party lab cavity sampling and IEP clearance, with extra documentation on rental properties where moisture history may be partial. Montclaire and the Goshen Road corridor see the standard newer-suburban pattern across most properties. The Cahokia Creek corridor properties on the west and north edge have additional surface-water exposure during heavy rain that contributes to layered contamination on a subset of properties. We document baseline conditions on rental properties carefully given the potential for partial moisture history.

“We don’t tell you it’s mold because it looks like mold. We test, we plan, and we tell you what you don’t need to remediate.”

How a Edwardsville call runs

Six steps. Same every job.

  1. 01

    Pre-test, surface and air.

    Sample sent to an independent accredited lab, not our own. The results decide what gets remediated, not our opinion.

  2. 02

    Containment built.

    Poly sheeting, ZipWalls, and negative-air machines establish a pressure differential. Spores don’t migrate out of the work area.

  3. 03

    HEPA filtration, 24/7.

    Air scrubbers run continuously inside containment. We measure pressure daily to confirm integrity.

  4. 04

    Materials removed under PPE.

    Drywall, carpet, and porous materials cut to a clean edge inside containment. PPE per IICRC S520.

  5. 05

    HEPA vacuum and antimicrobial.

    Every surface inside containment gets HEPA-vacuumed, wiped, and antimicrobial-treated. No shortcut here.

  6. 06

    Third-party clearance.

    Independent re-test before we tear down containment. You get pass-fail in writing. If it fails, we go back in, same price.
