Lead In Your Home Or Business


Making A Start

If you are in the process of renting or buying a new home, congratulations! The search process for a new home can be arduous, but when you have found the perfect place to raise your family, it will all be worth it. However, ensuring that your home is up-to-par on inspections and is hazard-free for you and your family is important. For homes built before 1978, conducting lead testing and inspections to ensure your home is not contaminated by lead based paint or other sources of lead is crucial. If you are worried about lead exposure for you and your family, this guide will help you navigate the ins and outs and show you what to do if you think your home or workplace may be exposed.

Lead In Your Home

Lead exposure in your home can happen in a number of ways. The first step is to identify possible sources of lead in your home to prevent exposure for you and your family. Common sources of lead exposure in homes and buildings include:

Lead-based paint in older homes and buildings.

If your home was built before 1978, it may contain lead-based paint. The use of lead-based paint in homes was banned in 1978, but 24 percent of homes built in the 1960s, 69 percent of homes built between 1940 and 1959, and 87 percent of homes built before 1940 contain lead based paint.  If lead paint is in good shape, it typically isn’t hazardous; the problem is when the paint starts to crack and chip. Surfaces that get a lot of wear and tear can be highly problematic because these areas are more likely to have chipped paint, which releases lead into the air. These areas include:

  • Window sills and tracks
  • Doors and surrounding areas
  • Banisters and railings that have been painted with lead-based paint
  • Gates and fences, especially in the handle area

"This company is great and goes above and beyond for their clients. I had researched other companies and heard about St. John Environmental and gave it a try. To say this company exceeded my expectations is an understatement. The owner goes over every last detail and leaves nothing untouched. If it’s not absolutely %150 up to standard he is not satisfied whatsoever. I love a company that can leave a job knowing there was nothing unfinished and did an awesome job. Highly recommended. If I could give more stars I would..”
