Lead was formerly used as an additive in paints and many other construction materials. Back then, the harmful impacts of exposure to lead were not considered. But today, lead is a recognized toxin, and the effects of lead absorption in the bloodstream are considered a health hazard. If you stay in a property constructed before the use of lead was stopped, there are chances that lead is present on your interior surfaces under new layers of paint. Detecting and treating lead can help eliminate health hazards. Lead abatement is required if there is exposure to any occupants of a lead-contaminated building as per the Ontario Ministry of Labour as well as the Occupational Health and Safety Act.


The lead abatement procedure:

If you suspect lead, professional lead abatement is the perfect solution for you. First, it is important to ascertain the presence of lead by opting for the services of qualified professionals. By making proper assessments, experts can tell you the level of lead present and the extent of the harm it poses. 

If lead is present, then professionals can help you achieve safety through one of the following ways:

  • By covering up the surfaces using alternative materials
  • By using bonding components to prevent chipping or flaking of lead-infused paints
  • By replacing doors and windows if the paint cannot be removed with safety
  • By removing lead through safety-approved removal techniques like wet hand sanding or wet hand scraping


At O'Reilly Brothers, we provide efficient lead abatement solutions. No matter how unique the challenge, you can trust us to deliver the safety you deserve.





When the contaminant is removed from insulation materials, installing a new insulation product may be necessary. There are safe alternatives that can help prevent further contamination problems and ensure good health for occupants. Some features that you should consider when looking for safe insulation material are:

  • It should resist moisture
  • It should not contain Volatile Organic Compounds (VOCs)
  • It should not cause gassing
  • It should be fire-resistant
  • It should be natural and sustainable
  • It should be easy to install



While mould and lead removal are necessary steps to ensure a safe and healthy environment, preventing their growth in the first place is key to avoiding the need for removal services in the future. Here are some tips on how to prevent mould and lead growth on your property:

  • Proper ventilation: Ensure that your property is well-ventilated, especially in high-moisture areas like bathrooms and kitchens. Use exhaust fans and open windows to increase airflow and reduce moisture levels.

  • Address leaks promptly: Water leaks can lead to mould growth and create a breeding ground for lead dust. Make sure to address any leaks in your property promptly, and dry any affected areas within 24-48 hours to prevent the growth of mould.

  • Monitor humidity levels: Keep the humidity levels in your property below 60% to prevent mould growth. Use dehumidifiers in areas that tend to be more humid.

  • Regular cleaning: Regularly clean and disinfect surfaces prone to mould and lead growth, such as bathrooms and kitchens. Use cleaning products that are effective against mould and lead.

  • Safe renovations: If your property was built before 1978, it may contain lead-based paint. Before conducting any renovations, have your property tested for lead and hire a certified professional to safely remove it if necessary.

By following these prevention tips, you can reduce the risk of mould and lead growth in your property, keeping you and your loved ones safe and healthy. Contact O'Reilly Brothers Ltd for efficient mould removal services to keep your family healthy and your property safe.
