How do you keep algae from growing on your house?
I have one side of my house that does not get sun. When we bought the house two years ago we had it washed and repainted. I thought that took care of the issue. I noticed that algae is starting to come back. I put landscaping paper down and mulch over the top in that area. Did that help keep it at bay or make it better for the growth? Short of cutting down the trees how can I keep this unsightly stuff from growing?

Spraying Wet & Forget mold and mildew remover on a house. If you live in a warm, humid climate, mold and mildew will often form on the exterior siding and trim of your home.

Hello Liz, sometimes I feel there is no solution. I have a similar situation I have a waterfront lake exposure in a cove thats somewhat downhill. There seems to be a consistent microclimate here where there is morning moisture collecting on the vinyl siding decking and deck rails. Actual water droplets on the white vinyl rails.
Not having sun or great ventilation causes the mildew and algae, I have a moss problem too. We tend to do a powerwashing yearly keeping our fingers crossed the finish on the pt deck will last. We particularly like the oxi products.
The one side of my house was covered in algae when I purchased it. I sprayed it with windex and wiped it off with a wet rag. I did not reappear in the two years after until I replaced the siding because it was not the color I wanted. Algae is really not hard to remove and expensive cleaners and harsh chemicals are not necessary.
