Sprinkler Systems May Cause Water Damage & Mold Growth

Posted on: September 4th, 2012 by Peter Sierck No Comments

Warning: Sprinklers may cause water damage and mold. How can that be especially when I am just watering my yard? Well when the weather gets dry and there is not enough rain in sight, we are watering extra to keep our yards from drying up. The problem with watering is that sometimes our sprinkler system isn’t working right.

Today many of us rely on automatic systems to do the watering for us. If we still stood outside and watered with a hose we wouldn’t spray the wall for 5 to 10 minutes at a time in the same place. Why do we let our sprinkler systems do that? I know in my case, and many of my neighbors, the sprinklers run at night and we don’t realize there is a problem until it is too late. Sprinkler systems are a wonderful convenien

ce in our busy lives, but we need to maintain them!

As mold and moisture inspectors, we at Environmental Testing & Technology (ET&T) frequently find sprinklers to be a major cause of mold problems inside buildings.

Here are some sprinkler system problems we at ET&T run into all the time:

  • Sprinkler spraying on the walls of the building (sprinkler overspray).
  • Plants and grass growing right up against the wall.
  • Sprinklers installed too close to the building.
  • Broken or leaking sprinkler pipes.

If your sprinklers look like the ones above, you may have a mold problem brewing and you may need a professional mold inspection!

Don’t let this sad mold story happen to you!

Our walls are like a sandwich. There is the outside wall, the insulating space and then the inside wall. The outside wall keeps getting wet from the sprinkler system, then the insulation material gets wet, then the inside wall gets wet.  Before you know it, you have a funny smell, then you have a water stain inside, then you see a small spot on the wall, baseboard, or flooring.  You clean off the spot, but the spot keeps coming back.  That spot is probably mold!

This photo is of an inside wall that had a sprinkler that sprayed the on the outside wall.

A small spot on the wall can mean a big problem inside your property.

If this is already your situation we can help! For a free phone consultation call Environmental Testing & Technology (ET&T) at 760-424-2259 or email us at to see if you need a mold inspection.
