So anytime I do urine removal I've always just done the waterclaw extraction and I charge by the gallon for the solution. That can get expensive pretty quickly, just had a customer where I had to use 6 gallons of solution x $40 a gal, was an extra $240 on their bill. Great for me, but not many customers want to spend that much extra. I know you can do topical with laying down heavy urine pre-treater and then extracting as usual with a wand (pretty common for 2nd floor urine problems anyways since you can't flood an upstairs) but I am curious how to charge for THAT particular style of urine removal. Obviously it can't get all the way into the padding and such like sub surface extraction can, but if that's what the customer wants, how would you guys charge for it? I know that's open ended and such, but just looking for some ideas. Charge a little extra per room? Charge per spot? Also, I'm pretty sure the urine pre-treaters don't work well on other stains, so would you let the urine chem work, extract and then do over with your normal pre-spray or could you just spray your normal pre-spray on after 10 minutes or so, once the pee chem has had time to work? I'm new to the pee removal here so any help is appreciated, oh and I'm in Oregon by the way if that gives anyone an idea of pricing. Thanks!
