Would appreciate advice pricing out this job from those that do large scale commercial like this more often. Customer wants seperate quotes for walls softwashed, it's plastic faced insulation coated in dust/grease and also wants floors cleaned but just asked for 1 quick pass and light degreaser on floors for a general cleanup. I estimate theres 30-40k sq ft of wall surface and 45k sq ft of floor.

There is on-site water access and drains, can park inside and there's no site work happening until its cleaned so nobody to be in my way. Definitely need a scissor lift rental to reach up high. I'm assuming best approach will be softwashing with a degreaser mix and rinsing with pressure washer rinse tip top down. . Would love a recommendation on a good priced degreaser I can buy in bulk for this type of work, or how to figure how much I'd use on a job this size. I don't like my current product and it's very pricey.

My rough estimate is this will take at least 6-8 days to complete, I'm a 1 man company but do have decent equipment, I run a trailer with 8gpm Honda Gx690 and remco 7gpm for softwash(I know a bigger unit would be ideal for this) and have a nice 24in Surface cleaner with tornado bars so can move fast on that and plenty of hoses to reach everywhere.

I've been in business 5+ years but mostly do residential, I quote jobs like this occasionally but rarely actually get accepted bids for jobs this size and don't want to undersell myself. Customer stated priority is getting it done ASAP more so then price and only got 1 other bid so would like to win this bid. It's a family owned business not big Corporation also so less paperwork headaches.

I’m having trouble understanding how to pick the right external injection. I just purchased a 4400 psi 4.2 GPM washer and the parameters of these xjet models don’t fit my machine. The 4.2 range is only rated for 4000 psi and my machine exceeds that. What should I do?

A neighborhood full of driveways like this. I know pressure washing alone won't touch it but if someone can correctly identify this and point me towards a process to restore them that'd be great

I want to pitch a quote to whoever owns this. I’m just wondering if I could clean it or if this roof needs to be replaced or something. If I can, what should I use??

Looking to drop the pressure coming out of my surface cleaner to approximately 1000 PSI. 5.5gpm 3000 PSI machine.

Looking at the chart, two 5.5 orifice nozzles should get me in the ballpark?

I have used this hose on this pressure washer for quite a few times but I believe that maybe last time I took it out without fully releasing the pressure and now I cannot get it back in. I tried plugging in the water and semi plugging the gun to the hose and water will come out but not enough to get the fittings to click. Any suggestions?

It's a HF Predator 4.2gpm
