We did a WC job a couple months ago and he mentioned getting his house washed, so we set up a date. A few days before the wash he gets back to me and says he “has concerns about environmental impact of SH” and asked if I could use “oxygenated bleach” on his painted cedar shake instead, and gave me a little lecture about switching to that instead.
I told him all I use for housewashes right now is SH and if he wants something more specialized to contact another company as I’m not even set up for that.
I posted a pic of the siding here and you all said it would clean up nicely with housewash, is there something I should know about painted cedar and SH?
It sounds to me like he’s just talking about sodium perc. I haven’t had anyone turn me away for using SH yet, but I’m sure one day I’ll get to have that conversation.
Maybe give him two quotes: one with your proven method and 100% guarantee, and another with HIS method/chems and no guarantee
If it is not that dirty, percarbonate, sodium carbonate, oxygenated bleach, soap and water etc… will work fine. if there are green areas, not so much. It is usually recommended that you scrub with a brush with those less powerful cleaners. You can clean the dirtiest house with just soap and water but you will be scrubbing till the cows come home. Id just charge double for their method, add a disclaimer that you will be disturbing oxidation due to extra scrubbing required, and put the ball in their court. You could also explain to them that bleach biodegrades into harmless elements rather quickly.
There’s a fair amount of black mildew on it, I’m letting it be someone else’s headache. He wants the inside of a large screen room done as well and wanted the strip lighting fixtures “wrapped”.
The one you linked is just water and 3-5% hydrogen peroxide. I don’t think DS’ing that is going to give you anywhere NEAR the strength you’d need to tackle even light mildew
You can order it online in powder. It works differently than SH. if you keep moving sodium percarbonate around it continues to work (agitation with a brush).
Most likely stems from horror stories of nuked bushes and plants after a clean, the only customers that worry are the ones that have been through it. Blame incompetence on the contractors behalf. If word of mouth is the best form of advertising then so are horror stories and false thinking about bleach.
