I got a call for a large house yesterday, she wants the usual done such as concrete and soffits. However her chimney is loaded with algae and what looks like soot…
I’m not really asking about what to use, my issue is the painted deck directly below. I can have someone hose it down thoroughly as I’m x-jetting but could use some advice from someone that has encountered this situation.
Yes on the painted wood. Just fyi doing chimneys like that is at least a $75 upsale. Going to take you awhile probably. If it’s a stained deck better have someone standing there rinsing. You’re probably going to need to hit that chimney 3-4 times with about a 5-10 min interval with a strong mix - think 4% or so. But that one not super bad so may not be too terrible.
Add in some ebc( $133 5 gallons) and you only need a few ounces. Im doing 2 chimneys like this Thursday. Most of them clean up pretty good with just strong bleach but its not a immediate result might take you 30mins reapplying and waiting. Definitely have the wife hosing down that deck.
On certain brick it will take a hotter mix. I’m no masonry expert but I’ve run into some porous red/white brick that takes 6%+. When I pull up and see it I’m not thrilled to realize I have to hit the entire house with such a hot mix because of the watering that’s necessary. It takes a lot longer. One of the few downsides to quoting without visiting.
Especially the white brick, but the results are amazing.
