Pretty much my methodology. I have washed a couple of blue and brown houses and been just fine but there are definitely risks that other colors donāt have.
Iāve seen the siding come out a lighter color post wash. The sh seems to make the oxidation more noticeable and appear to be lighter in color. Itās even more noticeable whem looking at an angle. If your going to do it put a warning in writing that such and such is possible so the customer knows what to expect.
Citrus house wash or cut your house wash in half only do one side at a time. If it has white soft you can use your regular just make sure siding stays wet and rinse it (water falling) like itās the first house you washed by yourself
I see black gutters and soffits and vinyl over entryways every day. Black garage doors are commonplace on the āmodernā style homes. Black aluminum trim is everywhere nowadays. Iāve even seen black stained concrete patios.
So if you all turn the job down, what do you say so that it comes across as professional as well as keeping the door open for future work with the customer?
I havenāt been in this situation yet but I imagine something likeā¦
" Sir/maāam Iāve finished my walk around site assessment and ive noticed a few things we need to talk over. Your deck has some boards that really should be replaced, but I can easily clean it. Iām more concerned with your siding, in my experience and the experience of other respected washing professionals, cleaning colors like brown blue red and green tend to produce suboptimal results. Some of the issues i/we have seen is pronounced streaking, sheen irregularities, and oxidation issues. In my opinion you might be better served leaving it as is, and allowing me to wash your other areas. "
So like the above just with correct spelling and punctuationā¦
There are enough customers in the world that if one or a hundred never calls you back it wonāt matter. Just tell them that the color may flash and you wonāt clean it
Iām not picky, just careful. I live in FL so itās a freaking color pallet of homes. Iāve done almost every color, except black. I do educate the customers on the oxidation but never a problem so far. I donāt soft wash, I downstream every house. I stay far enough when applying the mix to not agitate the oxidation. Donāt let dry and donāt use wand to rinseā¦I use my ball valve to do so while also keeping a good distance. If your mix did the job, thereās no need for pressure. Good luck!
Yeah, we have a āplannedā community of upscale homes slammed together like sardines and most of the Hardie board is colored. Kinda ups the pucker factor.
