Hello all. I have the opportunity to clean a retaining wall (split face block) and need some help pricing it. Do you price it out by linear foot like you would a vinyl fence or calculate the square footage and go with my regular rate that I charge for concrete? Or just guesstimate how long it will take and price accordingly? Any thoughts or input would be appreciated.
It is 350 feet long and averages about 4feet tall. I will go by tomorrow and do a couple test spots to see how easy/hard it will clean up. I am unsure how long it will take since I haven’t done any retaining walls, but most of the dirt looks to be mold/mildew/algae. There is some calcite which would have to be treated separately and priced accordingly but my main question is how to price it out. Any help is appreciated. Thanks.
I would be at 60-75¢ a square foot. I think pre treating with 3-4% would help but that’s the job of a turbo nozzle. I’ve done one of these that was 30 foot long at a house and was only 3 foot high. I had to turbo the whole thing. And with all of the crooks and crannies your gonna be soaked from head to toe by the end of it. I know I was…
I personally would price this one by the hour/day. The wall height is not even all the way down, so lnft, or sqft would be off as the wall height gets shorter. But really it shouldn’t matter, my sqft/lnft would match my hourly.
For this i would use my roof pump and spray a 4% pre treat, than come back with some pressure. Than depending on how it looks would post treat it.
Walk down along it spraying 4% mix, wait 5 min , turn around walk back the other way spraying same mix but hitting it again at a different angle, then use your adjustable wand to rinse. In fact last one I did, just used my downsized m5ds nozzle to rinse with. IBS right on 3 hours though. He’s younger than I so he likes to work harder than me though ie turbo nozzle, lol.
Look online, can get the tyvek suits $4.95 though to be honest that one not that bad. Good suggestion made hit with strong hw mix when you leave.
