Why Asbestos Matters in Florissant

Approximately 55% of Florissant's housing stock predates 1980 — the year federal NESHAP regulations effectively ended new asbestos use in most building materials. Common structures include brick ranch homes, post-war bungalows, 1950s–1960s suburban development.

Florissant is a St. Louis County north suburban city with significant 1950s–1970s residential development; approximately 65% of housing predates 1980, with asbestos common in ranch homes and mid-century commercial buildings.
Missouri DNR contractor licensing and 10-day notification to MDNR St. Louis Regional Office required under 10 CSR 10-6.250 for qualifying renovation or demolition projects.
Ranch homes and split-levels from the 1950s–1960s along New Florissant Road and Graham Road commonly contain asbestos in floor tile adhesive, pipe insulation, and HVAC duct wrap; older commercial buildings in the Florissant town center also contain ACM.
Federal law (40 CFR Part 61 Subpart M — NESHAP) requires notification to Missouri Department of Natural Resources (MDNR), Air Pollution Control Program; Saint Peters and Florissant (St. Louis metro) projects notify MDNR St. Louis Regional Office; Joplin (Jasper County) projects notify MDNR Springfield Regional Office at least 10 working days before qualifying renovation or demolition work.
Only Missouri Department of Natural Resources (MDNR), Air Pollution Control Program, Asbestos Unit-licensed contractors may legally perform asbestos abatement in Florissant.
Never disturb suspected asbestos-containing material without a licensed inspection. Friable asbestos releases fibers that cause mesothelioma, asbestosis, and lung cancer.

Are you licensed and accredited in Missouri?

Ask for their Missouri Department of Natural Resources (MDNR), Air Pollution Control Program, Asbestos Unit license number and verify it on the state licensing database. Federal AHERA accreditation is also required for supervisors and workers.

How will the asbestos waste be disposed of?

Ask for the name and location of the licensed TSCA-permitted disposal facility they use, and request a copy of the waste manifest. Do not accept vague answers.

What containment methods do you use?

Proper abatement requires critical barriers, negative air pressure machines with HEPA filtration, and full-body PPE. Ask for their written work plan before signing any contract.

Do you carry liability insurance and workers' compensation?

Ask for a certificate of insurance naming you as an additional insured. Minimum $1 million general liability for residential projects; higher for commercial.

Will you provide a written clearance air sample report after abatement?

Post-abatement air clearance testing by a separate third-party industrial hygienist is best practice and often required for commercial projects in Missouri.

Can you provide references from recent Florissant-area projects?

Ask for three references from projects completed in the past 12 months. A reputable contractor will have them readily available.

What does your written contract include?

The contract should include: scope of work, start and end dates, containment plan, disposal facility name, payment schedule, and a clause requiring regulatory compliance. Never pay more than 30% upfront.
