Why Older Homes are Prone to Mold and Mildew

Fighting mold and mildew in an older home feel like a losing battle. And why is that? According to an article in The Seattle Times, that’s because it was only after the oil shortages of the ’70s did the public begin to understand the value of conserving energy, including insulating and sealing a home.

Prior to 1974, writes the certified master inspector in the article, “builders had little incentive to add insulation because it increased the costs of the home and reduced profits to the builders. In many cases, the heating and cooling ductwork was not insulated to save on the costs of installation.”

Therefore, many older homes are prone to mold and mildew because of lack insulation in the attic, walls and foundation. Mold and mildew are always present, says the article, but “they must have moisture to survive,” and the reality is that cold areas of the home attract moisture.

The solution: “Keeping the ceiling and walls warm and dry is the first line of defense against mildew and mold formation.”
