How Do You Deal with Mildew on Siding?

One common issue that many Connecticut homeowners face is mildew that grows on their siding. This is not some shameful sign of neglect or uncleanliness. Rather, it is a normal, natural occurrence that can happen on any home. The question is, how do you deal with it? What should you do when you find mildew growing on the exterior of your Connecticut home?

Identifying Mildew on Your Home Exterior

Before we talk about how to get rid of it, let’s discuss how you know it’s there; what does mildew look like?

Mildew usually shows up as a dark green discoloration on the surface of the siding, though it can also appear gray, brown, or black. Sometimes it is a consistent film, and other times it has a more blotchy, irregular appearance.

In many cases, mildew can be subtle and harder to spot. You might not even realize you have any until you start cleaning, then the contrast becomes obvious!

For homes here in Connecticut, it is usually the north side of the home that receives the least sunlight, thus that is the side that tends to grow mildew the most, though it can also occur in shady areas like under decks and behind shrubbery.

How to Remove Mildew from Your Siding

Some people falsely assume that you can just spray off the mildew. The problem is that, even if you use a pressure washer, the fungal spores have not been killed, and the mildew can grow back.

The first step in removing mildew is to spray the wall with a fungicidal detergent to kill the organism, then you can wash the wall.

A pressure washer is the fastest, most aggressive way to remove the mildew from your siding. However, power washing equipment can be hazardous to use, with the possibility of property damage and personal injury. If you choose to do it yourself, research the process thoroughly in advance. The better route is to hire a professional house painting company that provides pressure washing services, or a commercial pressure washing company.

There is a safer, gentler option for the do-it-yourselfer. After spraying the fungicide, you can scrub the siding using a soft bristled brush or a sponge, with a mild soap. Rinse with a garden hose, and watch the mildew melt away!

Preventing Mildew on Your Siding

One way to save labor and keep your home looking fresh is to use an exterior house paint that comes with a mildewcide additive. The next time you have your home painted, talk to your Connecticut house painting company about the best exterior paint for your home.
