Cleaning Exterior walls of house, advice much appreciated

gacisco

Hey Everyone,

I was wondering if someone could give me some advice here. Live in the countryside in a 4 bedroom dormer. We have trees beside us which of course after every couple of years blow moss/algae/ onto the roofs which then starts flowing down the walls of the house.

I have to start cleaning it. It was done a couple of years ago by a guy that spray some chemical onto the house, left it sit for a few days in the dry weather and then came back and with high water pressure, cleaned it all off.

Brilliant job but can't afford this price every couple of years. Can anyone tell me whats the best way to go about doing it yourself.

The exterior walls are painted white. I read a couple of threads and scared to death now of using a pressure water system or particular types of chemicals.

A newbie when it comes to DIY. so help much needed. I just think doing it by hand with a bucket of water and some detergent would take forever.Forget about the roof, thats for another day but the house is about 2,200 square foot.

Thanks everyone.

As daithi said PLUS wear old clothing and a hat! Unless you are already fair haired - sprayed bleach falls everywhere! And a regular garden hose does the job for rinsing down - no need for a power hose which can take paint off the wall!

I have done this before and found that it works well.
