The short answer

Interior Windows and Doors

Friction surfaces on windows and doors are prime locations for lead paint. Opening and closing these over decades wears down the paint layers. This creates lead dust, which is easily inhaled or ingested. Proper precautions are needed before any renovation or repair work on these components in an older home.

Trim, Stairs, and Railings

Woodwork like baseboards, chair rails, and stair banisters were often coated with lead paint for durability. These high-touch areas can chip or be chewed by children, releasing lead particles. Sanding or scraping during a remodel spreads hazardous dust. Testing is advised before disturbing any painted trim in a pre-1978 house.

Walls and Ceilings

Lead was a common pigment and drying agent in wall and ceiling paints. It may be hidden under newer, non-lead paint layers. Water damage from a leak can cause paint to blister and peel, exposing the old layers. If you live in an older home, addressing water leaks quickly can help prevent this exposure risk.

This is a key reason to manage moisture in your home. Controlling indoor humidity and fixing leaks promptly helps preserve painted surfaces. It reduces the chance of disturbing lead-based paint. Proper drying after a leak is crucial to prevent paint failure and the release of hazardous materials.

Exterior Surfaces

Exterior siding, porches, and fences were frequently painted with lead-based products. Weathering causes this paint to chalk and flake off into the soil around the home's foundation. This contaminated soil then becomes a exposure pathway, especially for young children playing outside. Pressure washing or sanding these surfaces can aerosolize the lead.

  • Wood siding and clapboard
  • Porch floors, steps, and columns
  • Window sills and exterior trim
  • Garage doors and outbuildings
  • Metal surfaces like gutters and railings
  • Fences and garden sheds

Other Common Locations

Built-in features like cabinets, radiators, and fireplace mantels may have lead paint. Even some vinyl floor tiles from the mid-20th century contain lead. Demolition or renovation work can release this hazard into your home's air. It is safest to assume paint is lead-based until a test proves otherwise.

Special care is needed during water damage cleanup in older homes to avoid spreading contaminated dust or debris. The restoration process for water damage must account for potential lead hazards to ensure the home is safe after drying is complete. Communication with the water damage pros about the age of your home is important for planning a safe cleanup approach.

  • Kitchen and bathroom cabinets
  • Radiators and heating pipes
  • Fireplace surrounds and brick
  • Original hardware and door knobs
  • Basement beams and concrete floors
  • Some older floor tiles and adhesives

Frequently asked questions

How does water damage affect lead paint?

Water leaks cause paint to blister, peel, and crumble. This disturbs old lead paint layers, releasing chips and dust into the home. Wet materials also make safe cleanup more difficult. Fixing leaks quickly helps contain the hazard.

What should I do if I suspect lead paint during a water leak?

Avoid sanding, scraping, or disturbing the area. Contain the water damage and call a qualified water damage restoration professional. They can help dry the structure safely. For lead paint assessment or removal, you need a separate, qualified lead abatement professional. The two types of pros have different specialties for handling these distinct hazards.

Can my home in DeSoto still have lead paint?

Yes, any home built before 1978 likely contains some lead paint. Many American homes from that era still have original paint layers. If you are planning renovations or dealing with peeling paint, consider getting a test from a qualified professional. This is true for homes in many communities with older housing stock.
