Why Old Homes Are High-Risk for Lead

If your home was built before 1978 — the year lead-based paint was banned in U.S. residential construction — it’s highly likely that lead is present somewhere inside.

Where Lead Typically Hides

  • Paint on walls, trim, doors, windows, and porches
  • Soil near the foundation or in garden beds
  • Plumbing made of lead pipes or with lead soldered joints
  • Dust from renovation or wear-and-tear
  • Old tiles, caulks, or varnishes

Even beautifully maintained homes can have lead lurking beneath the surface.

Why Testing Matters Before You Move In

Lead is especially dangerous for:

  • Children under six — it can cause brain and nervous system damage, lower IQ, and behavior problems
  • Pregnant women — lead can harm developing babies
  • Pets — they can ingest lead dust while grooming

Testing gives you peace of mind and helps you:

  • Plan safe renovations
  • Protect your family
  • Meet local health and safety requirements
  • Negotiate repairs or remediation with sellers
Hand scraping paint from a wall with a putty knife — disturbing old paint during home renovation is the most dangerous moment for lead exposure, releasing dust and chips that are invisible but immediately hazardous

How to Test for Lead in an Old Home

  • Use a Lumetallix Lead Test Kit to check painted surfaces, window sills, floors, and soil
  • Hire a certified lead inspector for full-home testing (especially if major renovations are planned)
  • Test water from taps if plumbing is old or questionable
  • Check vintage items like glazed tiles, bathtubs, or old furniture

Smart Moves When Buying an Old Home

  • Ask the seller for any lead disclosures or past inspection reports (required by law in most U.S. states)
  • Budget for lead-safe repairs or abatement if testing finds a problem
  • Hire contractors certified in lead-safe work practices if you renovate
  • Keep young children and pets away from work areas during repairs

Preserve the Charm, Protect Your Family

Buying an old home is an exciting journey — full of character, history, and potential. By testing for lead before you unpack the first box, you safeguard your investment and the people you love.
