What Is Lead Paint and When Should You Worry?

Lead was a common additive in paint for much of the 20th century, prized for its durability and vibrant color. The federal government banned its use in residential paints in 1978 due to severe health risks. If your home was built before this year, it is likely to have at least some layers of lead-based paint underneath newer coatings.

This history means that many older homes across the country contain this legacy hazard. The paint itself is not a problem if it is fully intact and covered. The danger arises when the paint deteriorates into dust or chips, or when it is sanded, scraped, or otherwise disturbed during repairs or renovations.

Water damage from a leak or flood can quickly turn lead paint into a major hazard. Moisture causes paint to blister, peel, and crumble, releasing lead dust and chips into your home. If water-damaged building materials like drywall or plaster contain lead paint, the entire cleanup process becomes more complex and dangerous.

Standard water damage restoration can disturb these surfaces, spreading contamination. This is a key reason to involve qualified water damage pros for an inspection after any significant leak. They can identify potential hazards and recommend the correct specialists to safely handle materials that may contain lead, ensuring the job is done without putting your household at risk.

• Peeling or blistering paint on walls or ceilings after a leak.
• Cracking or chalking paint on window sills and door frames.
• Dust accumulation around water-damaged baseboards or trim.
• Paint debris in standing water or wet materials.
• Disturbed plaster or drywall that may have old paint layers.
• Any renovation work in a pre-1978 home that involves cutting or sanding.

Never dry sand, dry scrape, or use a heat gun on lead paint, as these methods create toxic fumes and dust. For small jobs, wet methods are safer: keep the surface wet while scraping and use a HEPA-filter vacuum for cleanup. For larger projects, including repairs after water damage, you must hire a qualified lead abatement contractor.

These professionals follow strict safety protocols, including sealing off the work area with plastic, using protective gear, and employing specialized HEPA filtration equipment. They are trained to remove or contain lead-bearing materials safely. After abatement, a clearance test is performed to ensure no hazardous dust remains before the area is reopened for use.
