Concrete cleaning pricing


This is like countypowerwashers on drugs


Sounds like very sore legs to me, I would run from that one while i still could lol.
Or sub it out to a company that has the equipment to get it done in a reasonable timeframe.
The floor scrubber Nashville Wash suggested is worth considering.


Ok I appreciate the info but I wasn’t trying to mislead anyone. Those are the specs to the pumps I bought thats all I had to go by. I guess I can get a pressure gauge and check to see what I’m actually producing. Anyway I have about 26 horsepower there between
the two so I should be close to a 3500psi 8gpm machine when running in tandem. That was my main point when letting you know what equipment I had.


No where close to it when you have back flow valves in play. Ever tried to blow through one? You can’t. Takes a good bit of pressure to open it. Also, your psi has almost nothing to do with how well and fast you can clean. You MUST know your actual gpm. I can run a 28"-32" sc on my 8. You’re gonna be lucky if you can walk at a leisurely pace trying to push a 20" sc. Not trying to be mean, but I have real world experience with 2 real 4 gpm machines ran together with back flow valves. Still had to walk at a boring pace with a 20". I’m just trying to save you the headache I went through. I washed about 75 dock doors for Walgreens distribution center the way you’re wanting to do, and it sucked. That was with no reclaim (didn’t use chems), and only washing the slippery crud in between trailers and around steps. Nothing asthetic, so it didn’t even have to look good. Put my ocd way in overdrive.


In all honesty, I would refrain from quoting. In my opinion you are nowhere near ready to take on a job this size given your equipment and your lack experience. If the customer want this every 30 days or so, you would start directly after you finish, continuously, making 0 sense. This is a job for a sizeable crew with way better equipment than you or I have.

If you think the floor scrubber can get the job done right, you can quote it much cheaper, do it faster and avoid trouble. I would hate to hear about you getting hurt, sued or lose money.


Will the building be empty?

And if they want it done so often maybe you only need to do one major wash, then only maintain the floors monthly.

Do you have pics?


@Racer how does that mondo perform with your 8gpm machine when compared to a 20”. I’m bidding a huge flatwork job that I can’t imagine doing with my 20”. If I get the job I’m considering going the mondo route. Is it any faster? It’s my understanding that the bigger you go the slower you go so what’s the benefit? The most I have done with the 20” in one night is 15k. That’s with pretreatimg w/ house wash


How bad is it? Is it fairly smooth? Got a pic?


The only picture I have is satellite. I’ll try to get some real pictures this week. It’s not that bad. Fairly smooth and it was cleaned 2-3 years ago. Very little shade.


Just published video - here you go. The only thing I would do if getting one is add another set of castors in the middle, kind of like anti-scalp wheels on a riding mower. You can see in the video that if you have some deviations in the concrete that the skirt will hang up some. The friend I was helping also has a 60" Sidewalk Solutions cleaner that doesn’t have that problem because of the wheel spacing, since it’s configured more like a big guy. How many square feet you doing. It can be a big time saver on a large job.


@Racer Thanks for the video. It’s roughly 60-70k sqft


My goodness. There’s a lot to take in with this post. I can’t imagine trying to bid a job of that scale with that equipment. Not to mention the two 500lb rated straps holding that buffer tank. That is grossly unsafe. I also strapped my IBC tote but each strap on mine is rated at 3,333 pounds. Also, if they truly want it cleaned monthly then you will have no time to take on other jobs so you’d have to build in enough profit to keep you going year round. And then you have the issue of wearing out your equipment at a rapid pace so you need to price for new equipment probably twice a year.


This is an old post


Yes it is. I hadn’t seen it before and I’m home with some unknown illness and boredom has fully set in. Sorry.


No worries. Just a heads up. I resurrected it for other reasons. I’ve read entire post without looking at the date before and it’s always frustrating in a funny type of way.
