I've been getting quite a few people contacting me lately about pressure washing questions, so I thought I'd start a new thread here so that if any of you have any questions, you could ask away. One of the most valuable members to ever grace PaintTalk, (to me at least), was a gentleman by the name of Ken Fenner of PressurePros. Not only did he contribute absolute gold when it came to all things pressure washing, he also authored some of the most helpful and insightful threads... Got questions about pressure washing?

I’ve got a small part time pressure wash business. Last few years I’ve just ran it out of my truck but I’ve got a trailer now and I’m going to expand to make it alittle easier and more efficient. Right now I’ve got a 3200 psi 2.5 gpm Simpson PW and I’ve just used pump sprayers to apply chem. The question is.. if I’m going to invest in more equipment/setup should I get or build an actual soft wash system with a 4.5-7.0 gpm pump or should I use my pressure washer to down stream? The majority... Pressure Wash Business ..read more

Hello all, I am contemplating subbing out the power washing for all my exterior jobs. I have contacted a local business and received quotes from him. Pros: 1) He has better equipment and knowledge. 2) He has the insurance for that type of work. (I am covered for pressure washing, but he has better coverage) 3) It frees up a day (each exterior) for me to be making more money on other jobs. 4) One less piece of equipment to maintain and load in/out of my truck. 5) I may get some good leads...

Instead of climbing on a roof and using a pump sprayer for application, I've tried down streaming standard bleach with soap for roof cleaning without rinsing. Full strength isn't strong enough. Still too much water. Will stronger pool bleach make the mix strong enough to get the job done. I can usually soak down the entire roof from the gutter line in minutes. With all the black roofs around I'm looking for an easy and safer way of dealing with them. Anyone doing this or am I totally... Roof Cleaning Question ..read more
