Lead Detection


Lead-based Paint

We perform the following types of property inspections for lead:

Lead-based Paint – we use an XRF lead paint analyzer that gives results on the spot.

Lead in Soil – this takes about a week to get results

Lead in Water* – this also takes about a week to get results

City water supply companies will give you a report on the water quality for free that will include any lead in the water. You would only want to test the water in your home if you think the plumbing from the street to your faucet contains a source of lead that can leach into your drinking water.

If your child’s pediatrician received an elevated lead blood level for your child, that physician is required to report it to the CA Department of Public Health. The CDPH issues a Notice of Lead-based Paint Violation siting the areas for clean-up. See these Lead-based Paint Contractors Upon completion of the lead-based paint cleanup, we can perform the necessary clearance documents for the NOV.  We provide lead-based paint inspections pre and post removal.

Lead Clearance Inspections

Lead clearance testing makes sense because you can’t see or feel lead in dust.

Abatement means any measure or set of measures designed to safely and permanently eliminate lead-based paint hazards.  Common sense indicates that, since you can’t see, smell or usually taste lead, that leads clearance testing should be done before rebuilding.

Lead clearance testing uses lead test swabs (a baby wipe-like cloth) inside the square black template you will see in your photos.

Lead removal includes, but is not always limited to:

  • The removal of lead-based paint and lead-contaminated dust, the permanent enclosure or encapsulation of lead-based paint, the replacement of lead-painted surfaces or fixtures, and the removal or covering of lead-contaminated soil; and
  • All preparation, cleanup, disposal, and post-abatement clearance testing activities associated with such measures.

Specifically, lead removal includes, but is not always limited to:

Projects for which there is a written contract or other documentation, which provides that an individual or firm will be conducting activities in or to a residential dwelling or child-occupied facility that:

  • Shall result in the permanent elimination of lead-based paint hazards; or
  • Are designed to permanently eliminate lead-based paint hazards and are described in paragraphs (1) and (2) of this definition

Projects are resulting in the permanent elimination of lead-based paint hazards, which are conducted in response to state or local abatement orders.

  • Abatement does not include renovation, remodeling, landscaping or other activities, when such activities are not designed to permanently eliminate lead-based paint hazards, but, instead, are designed to repair, restore, or remodel a given structure or dwelling, even though these activities may incidentally result in a reduction or elimination of lead-based paint hazards. Furthermore, abatement does not include interim controls, operations, and maintenance activities, or other measures and activities designed to temporarily, but not permanently, reduce lead-based paint hazards.

If lead-based paint is found and lead abatement is performed, before containment and engineering controls are removed, dust wipes are used for lead clearance testing.  Lead wipes look similar to a baby wipe; however, a different chemical is used.  For lead clearance testing a 12″ x 12″ square is wiped vertically and horizontally covering the entire area once.  This lead wipe is then put in a zip-lock bag and labeled.  These lead test swabs are then analyzed by an environmental laboratory. If the results from the lab show lead to be within an acceptable range, then containment and equipment are removed, and your contractor can then rebuild.

A final lead clearance testing report is then issued.
