Knowing the age of your home is a simple first step in ensuring a healthy environment for everyone living inside its walls. Newer or recently updated homes, which tend to be tightly insulated, can be more susceptible to the growth of mold. If your house was constructed before 1978, it is likely that lead paint is present somewhere within it. Repairs and renovations in older homes, done without the necessary safeguards, can increase the chance of lead poisoning and children are at the greatest risk for harm. To help with a careful evaluation, whether you’re concerned about lead or mold, we’ve put together some frequently asked questions with our suggestions to guide you as you assess your home’s environmental health.
