Lead Testing and Removal FAQs, answered by experts

Lead paint test kits are not always accurate. Several factors can play into why a test kit provides an inaccurate result such as user error, sample viability, the age and condition of the paint, or difficulty interpreting the final result. If you are looking for 100% accuracy, hiring a professional lead paint test is the only way to get that piece of mind.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Results from professional lead testing are typically available within a few days to a week (2-7 days), depending on factors like laboratory processing times and the volume of samples being analyzed. Expedited services may also be available for urgent situations.

Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.

DIY lead testing kits are available, but they often lack the accuracy and reliability of professional services. Professional testing is recommended for more accurate results, as properly certified testers can provide a thorough analysis, clear recommendations, and the necessary legal documentation if remediation is required.
