Lead-Safe Painting for Pre-1978 St Louis Homes
A large share of St Louis housing was built before 1978, when lead-based paint was still legal, which means most exterior repaints and many interior jobs in neighborhoods like Shaw, Tower Grove South, and Benton Park fall under federal lead-safe work practice rules. This guide explains what those rules require, how to confirm your painter is certified, and what it adds to a project cost and timeline.

Why this applies to so many St Louis homes
The EPA estimates about three-quarters of homes built before 1978 nationwide still contain some lead-based paint on interior or exterior surfaces. St Louis has a higher-than-average share of pre-1978 housing stock, particularly in South City neighborhoods built between 1900 and 1950.
If your home was built before 1978 and the paint job involves disturbing more than a small amount of existing paint through sanding, scraping, or heat-gun removal, the EPA Lead Renovation, Repair and Painting (RRP) Rule applies.
What the RRP rule requires
Painting firms doing this work must be EPA Lead-Safe Certified, and at least one person on the crew must have completed EPA- or state-accredited RRP initial or refresher training. Certified firms follow specific containment practices: plastic sheeting under work areas, wet sanding or HEPA-vacuum sanding instead of dry sanding, and proper cleanup verification.
Homeowners can ask a contractor directly for their EPA Lead-Safe Certified Firm number, which is searchable through EPA's certification database, before signing a contract.
Missouri-specific lead licensing
Missouri's Department of Health and Senior Services runs its own Lead Licensing Program (health.mo.gov/safety/leadlicensing), which separately licenses lead abatement professionals, supervisors, and inspectors for full abatement projects, distinct from routine RRP-covered repainting.
If your project moves beyond standard repainting into full lead abatement, such as removing lead paint down to bare substrate across a large area, it likely falls under the state abatement licensing program rather than the RRP rule alone, and you should confirm which category applies with your contractor.
What lead-safe work adds to cost and timeline
Expect a lead-safe surcharge of roughly $500 to $2,000 on a typical exterior repaint, covering containment setup, specialized cleanup, and waste disposal. Interior jobs that only involve painting over intact paint in good condition, without sanding or scraping, usually do not trigger these added costs.
Lead-safe containment can add a day or two to a project timeline for setup and teardown, which is worth factoring into your scheduling expectations.
Questions to ask before hiring
Ask whether the firm is EPA Lead-Safe Certified, whether the specific crew members on site have current RRP training, and whether their bid already includes containment and lead-safe cleanup or treats it as an add-on.
If your home has small children or is a rental property, also ask about post-job dust wipe clearance testing, which some Missouri-licensed lead risk assessors can perform for added assurance beyond the minimum RRP requirement.
Typical cost ranges
| Interior repaint, no lead disturbance | $3,500 - $7,500 |
| Exterior repaint with lead-safe prep | $6,500 - $13,000 |
| Lead-safe containment surcharge | $500 - $2,000 |
| Dust wipe clearance testing (optional) | $150 - $400 |
| Full lead abatement (separate scope) | $8,000 - $20,000+ |
Ranges are general estimates gathered from homeowner-reported quotes, not an offer or a quote for your project.
Common questions
How do I know if my St Louis home has lead paint?
Any home built before 1978 is presumed to potentially contain lead paint under EPA rules; a certified risk assessor can test specific surfaces if you want confirmation.
Is it more expensive to paint an older St Louis home?
Yes, when the work disturbs existing paint, lead-safe containment and cleanup typically add $500 to $2,000 to an exterior repaint.
How do I verify a painter is EPA Lead-Safe Certified?
Ask for their EPA Lead-Safe Certified Firm number and check it against EPA's public certification database.
Does painting over intact old paint require lead-safe certification?
If the surface is in good condition and no sanding or scraping is needed, RRP requirements generally do not apply, but confirm the surface condition with your painter first.
Who licenses lead abatement professionals in Missouri?
The Missouri Department of Health and Senior Services Lead Licensing Program licenses lead abatement supervisors, workers, inspectors, and risk assessors.
