Lead Testing

Lead testing identifies lead-based paint, lead dust, and lead in water in homes built before 1978 — the year residential lead paint was banned in the United States. We combine non-destructive XRF surface analysis with paint-chip and dust-wipe sampling analyzed by an independent accredited laboratory, following the federal EPA and California lead-safety protocols.

What is Lead Testing?

Lead testing and any work that disturbs lead paint in California are regulated activities governed by the federal EPA Renovation, Repair, and Painting (RRP) rule and California lead-safety programs, which set the standards for testing, sampling, and abatement. A lead inspection combines three independent data sources: a portable XRF (X-ray fluorescence) analyzer that reads paint composition through the surface non-destructively across every room, paint-chip samples sent to an accredited laboratory for layered cross-section analysis (lead-based paint is often buried under newer non-lead layers), and dust-wipe samples from window sills, floor edges, and stairwell treads — the surfaces where lead-dust accumulates and creates the primary exposure pathway for children. Water samples drawn at multiple fixtures complete the picture when older galvanized or pre-1986 copper plumbing with lead solder is present.

When You Need It

Any time you're under contract to buy a California home built before 1978, before any renovation that will disturb painted surfaces in a pre-1978 home (federally required RRP rule applies), when a young child has a confirmed blood-lead level above CDC guidance, when state-mandated abatement is triggered by a Title 17 enforcement action, and as part of a real-estate disclosure exchange where the seller has reported known lead-based paint. Los Angeles' significant pre-1978 housing inventory — Spanish Colonial bungalows, mid-century ranch, and craftsman homes are particularly common in our service area — makes lead testing a routine step in any inspection contingency on those properties.

Signs to Watch For

  • Home was built before 1978 (federal residential lead-paint ban)
  • Planned renovation that will disturb painted surfaces
  • Young child in the home with elevated blood-lead level
  • Visible chipping or peeling paint on door jambs, window frames, or trim
  • Real-estate transaction in a pre-1978 LA neighborhood
  • Older galvanized plumbing or pre-1986 copper with lead solder
  • Title 17 abatement order or local health-department notice

Our Lead Testing Process

  1. 1. Pre-inspection review

    Review the home's build year, renovation history, and any prior lead testing or abatement records. Identify rooms and surfaces most likely to retain original (pre-1978) paint layers — typically door jambs, window frames, baseboards, exterior trim, and older built-ins.

  2. 2. XRF surface analysis

    Portable XRF analyzer scans every painted surface in every room — reads through up to a quarter-inch of newer paint to detect underlying lead. Each reading is documented with location, layer count, and lead concentration in milligrams per square centimeter. EPA action level: 1.0 mg/cm².

  3. 3. Paint-chip + dust-wipe sampling

    Targeted paint-chip samples from suspect surfaces sent to an accredited laboratory for layered cross-section analysis (XRF reads the surface only — chip samples confirm interior layers). Dust-wipe samples from window sills, floor edges, and high-traffic surfaces measure ongoing exposure risk in micrograms per square foot.

  4. 4. Water sampling (when warranted)

    First-draw and flushed water samples drawn from kitchen and bathroom fixtures, sent to a state-certified drinking-water laboratory. Indicated when the home has galvanized or pre-1986 plumbing, or when a child has confirmed elevated blood-lead with no paint source identified.

  5. 5. Written report + protocol

    Comprehensive report listing every surface tested, lead concentration, EPA classification (lead-based, lead-containing, or non-lead), and California lead-safety (Title 17) recommendations. If abatement is required under Title 17, we provide the written protocol for a licensed abatement contractor to follow.

What to Expect

A standard pre-1978 California home lead inspection runs $400-650 for surface-only XRF analysis with a written report; comprehensive inspections that add paint-chip, dust-wipe, and water sampling typically run $650-1,200. Inspections take 2-3 hours on-site for a typical single-family home; the lab turnaround for chip and dust analysis adds 3-5 business days. If abatement is required under California Title 17, costs are highly variable — surface-encapsulation projects can run $1,500-4,000 per room, while full removal-and-replacement of original lead-painted trim and door jambs in a craftsman home can exceed $25,000. We coordinate the inspection report directly with abatement contractors and with your transaction's title and escrow team.

Lead Testing

Understanding Lead

Lead exposure is most dangerous for young children, and pre-1978 homes are the most common source — here is where it hides, how it is tested, and what to do before you renovate.

  • Lead-based paint

    1978US residential ban

    The United States banned lead in residential paint in 1978. Homes built before then often still carry it on original trim, window frames, doors, and built-ins, usually buried under newer non-lead layers that wear through at friction points.

  • Lead in drinking water

    pre-1986plumbing risk

    Lead can enter drinking water from old galvanized pipes, lead service lines, and the lead solder used on copper plumbing before 1986. First-draw water sampling at the fixture is how that exposure pathway is measured.

  • Lead dust and soil

    The biggest everyday exposure is often not the paint itself but the dust it sheds at friction points — window sashes, doors, stair treads — plus lead-contaminated soil tracked indoors. Dust-wipe sampling targets exactly these surfaces.

  • Why children are most at risk

    There is no known safe blood-lead level in children. Even low exposure is linked to lower IQ, attention and behavior problems, and developmental delays, because young children absorb more lead and frequently put hands and objects in their mouths.

  • How lead is tested

    A portable XRF analyzer reads paint composition through the surface non-destructively in every room, paint-chip samples confirm the buried layers at an independent accredited laboratory, and dust-wipe and water samples capture the active exposure pathways.

  • Before you renovate

    Disturbing lead paint in a pre-1978 home — sanding, scraping, demolition — is regulated, because it spreads lead dust. Testing first tells you which surfaces need lead-safe work practices or abatement and which are already clear.

Common Questions

How much does mold inspection and removal cost?
A standard mold inspection runs $400-700 depending on home size and the number of air samples taken. Full remediation is highly variable — a single contained area might be $1,500-3,500; whole-house remediation after a flood can exceed $15,000. We provide a written quote after the inspection and never charge for the quote itself.
What is EPA RRP certification and does my contractor need it?
The EPA Lead Renovation, Repair, and Painting (RRP) rule requires that any contractor disturbing painted surfaces in pre-1978 homes hold firm-level certification AND employ certified renovators on the job. California adds a separate CDPH Lead-Related Construction Inspector certification for testing work. Both are non-negotiable for legal lead work in California — ask for the firm certification number on the contract; the EPA maintains a public lookup at epa.gov.
How is lead-based paint tested in a California home?
Lead paint is tested non-destructively with an XRF (X-ray fluorescence) analyzer that reads paint composition through the surface, plus targeted paint-chip samples sent to an accredited lab for the layered cross-section. We also dust-wipe sample window sills, floor edges, and any disturbed areas where lead-dust accumulates — these readings drive the EPA's risk classification. Reports include each room's lead status and any mandatory abatement work under California Title 17 if the home was built before 1978.
Do you offer radon, lead, and home inspection in addition to mold services?
Yes. In addition to mold inspection and remediation, our California operation provides radon testing, lead testing, moisture and indoor-air-quality testing, and full home and commercial inspections. That means a single visit can cover several environmental concerns at once, with lab work handled by an independent accredited laboratory. If you need a service we do not provide, we are happy to refer you to a licensed specialist.
