This house wash I have coming up has stucco, painted siding, unpainted cedar, an unpainted pergola, and a composite deck all in close proximity. I haven’t had much experience cleaning wood so I’m researching that now. What would your process be for cleaning these surfaces? Just top to bottom with HW mix? Is there anything you see that I need to look out for? Any input is appreciated
Did you price for the pergola and deck to be washed, or just the house? You lack pictures along with a good description of what you’re getting in to, to receive any useful advice. Have you washed anything before?
Yeah, thanks Max. Sorry for being vague. They want the pergola, deck, and house washed. I didn’t take many pictures. The rest of the home is pretty straightforward, it’s all board and batten, but this section has a lot going on. I’ve only been doing this around a year but I’ve washed a good amount of homes and I’m feeling more confident taking on decks and stuff. This looked a little more complicated than what I’m used to though and I just didn’t want to overlook anything
You’re gonna find there are a lot of angles and facets going on, so price higher than you’d think possible.

If your intent is to hit that pergola with 4% HW it will end up turning white and sloughing off wood that UV damaged wood leaving it fuzzy and requiring sanding. It looks like it might have had some protection applied at one time but whatever it was is burned off. I would go easy on it and use sodium percarbonate followed by oxalic. You can always go stronger if need be. There will be a lot of detail work and watch your pressure so you don’t leave marks in the wood. Make full strokes on boards and fan away as you come to the end of the stroke.
