"As soon as we sent out the need for testing, they had called right away on a Sunday, and the owner was able to book an appointment for the next day for testing! He tested every floor, and expedited the testing for us to ensure we knew the results right away. We are really grateful for how quick this process was and how accommodating their team is. Also, the price is very reasonable! 10/10 would book through Red Diamond Mold again!"

Lead Testing and Removal questions, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Professional lead removal involves identifying and safely removing or encapsulating lead-based paints and materials, using specialized equipment, and following strict safety procedures to minimize exposure and contamination.

Properties should be tested for lead every 2-3 years, especially if they are older, have undergone renovations, or show deterioration of paint or interior finishes.

You should ask a few questions to ensure that your potential lead removal professional is experienced and qualified to handle lead-paint abatement safely, legally, and properly.

  • What are your qualifications and experience removing lead-based paint?

  • Are you licensed and certified to remove lead-based paint?

  • How do you test for lead paint?

  • What methods do you use for lead-based paint abatement?

  • What do you plan to do with the hazardous material when you remove it from the home?

  • Do you do replacement and painting work or removal only?

Lead removal services typically cost between $1,000 and $5,000, depending on the extent of lead presence, the property size, and the complexity of the abatement process.
