As a homeowner, mold is one of those things that you hope to never encounter. Unfortunately, even if you've made every effort to keep the interior of your home dry and mold-free, you may still have some mold damage outside. Moisture can build up under your home's eaves, and it's an ideal environment for mold growth because there's very little sun exposure. If you think that you're seeing signs of mold growth under your eaves, you need to address it immediately. Here are some tips to help you clear it out and disinfect the entire area.
Choosing the Best Cleaner for the Job
You'll need to make sure that you treat the area thoroughly with a cleaner that will disinfect the whole area. The disinfection is essential, because it helps to keep the mold from coming back. The best thing you can use in this type of environment is either a commercial fungicide or a solution of chlorine bleach diluted in water.
Washing Away Any Mold
Start by treating the whole under-eave area with a pressure washer. This washes away any existing spores of mold on the surface. Make sure you have a consistent water supply, then you can set the pressure nozzle so that the stream is moderate. Don't go with the high setting, because that would be too much pressure – it could damage the area.
Stay back several feet from the house when you do this part. Direct the water stream straight into the under-eave space to wash out the mold. Keep the stream moving in a steady, consistent pattern. You don't want to leave it in any one place for more than a second or two at a time, otherwise you could damage the wood and paint.
Disinfecting to Prevent Return
After you've washed away all of the mold from under the eaves, create a mixture of bleach and water in a ratio of two or three parts bleach to one part water. If you're using a commercial fungicide instead, prepare it according to the manufacturer's instructions, as it will probably need to be diluted with water. Then, cover the ground under the eaves with tarps and brush the liquid directly in the areas affected by the mold.
If you're concerned about the presence of mold in or around your house, you can also hire a mold remediation specialist to help you get rid of it.
