Been asked to quote for this pressure washing job on a roof. Have a price in my head just checking I am about right
cheers craig

What size, access, water supply, drainage, possible grief if something goes pear shaped and how much do you want the job ?
-
Done a few similar in Manchester. This one on the link we did in roughly 12 hours split over 2 days. The building has an elevator so we took up a washer to the 4th floor and out onto a balcony. 50 meters of HP hose and this flat roof was up a level up from the 4th which we got to by fixed ladder. Water supplier was on the roof. Was approx 400m2. 400 quid.

£1 a sq m just sounds incredibly cheap for some reason.
I would expect it to be more like £3 but I have no experience in this field and could be talking utter rubbish.

A lot of time is spent setting up and pushing water to the drains with squeegees. It's only algae on the surface. Piece of pi$$. Could have put 2 machines on and had it done in one day if it weren't for the flow of the water source only being sufficient for one machine.
I'm not suggesting a quid per m2. That's just what we did it for which is reasonable to who the client is who we do a lot of work for.

On that subject, I've been asked to quote for the stone cleaning of two cornices on the outside of a fairly high (5 stories) building in the City of London - can anyone help?
-
hi pristine some pictures might just be helpfull
regards john

A site visit would be more helpful still :-) - I was just being lazy and I've managed to summon the energy to get someone to go down there for me...
Thanks anyway.

hi, been asked to quote a couple of tennis courts (standard size) - what is the average going rate for these (metres)?? - also any ideas how much water / how long thell need as only have 350 litre tank??
Cheers,
Rob

Hi Rob
If they are a porous macadam surface I would charge £350 per court although if very mossy/dirty I have charged up to £900, average time to clean one would be 1 1/2 days.
You need to be careful you don't destroy the surface and its always handy to have a tennis court sprayer in mind if it needs re-colouring.

Hi Rob
I use a 200ltr plastic drum with a feed from clients own water supply.
FSC first then wash down with lance.
BTW you may get better prices where you are but I'm down in the South West.
Regards
Cliff

OK - cheers Cliff.
What does FSC stand for?
What other surfaces do you tend to do - concrete? - not sure on any other tennis surfaces that can be done (grass is obviously no - presume clay is no as well?)- havent played in ages.
Im South - East - so i n terms of per day that sounds about right
Cheers,
Rob

hi rob125 get your self a descent power unit a fully plumbed bowser a water boom
then you can do 2 courts a day

With respect the only way I could do two a day was if they were fairly clear of moss etc otherwise there just wash downs, don't see many of those down here, mores the pity, courts here are mostly porous macadam and being wet in the West Country mostly full of moss. I have not had much success using the water broom I don't find its man enough for the job.
Rob
By "concrete do you mean "no fines concrete" if so treat as you would porous macadam.
Dense acrylics will be the hardest to make look good as they tend to show the cleaning marks.
You cant pressure wash synthetic grass, you usually have to power brush them and replace sand, with clays they require "forking" and dragging and may even have to have there surface replaced.

Hi Cliff, - do you ever use chemicals (even if before / after to kill weeds?) to help cleaning the courts or is generally pressure washing adequate??
cheers,
Rob

Rob
Have never used chemicals

Don't assume you shouldn't use chemical though just because Cliff doesn't.
With the courts we've done, we pre sprayed with hypo to soften the moss and lift the algae. These surfaces were painted tarmac and safety rubber. Large areas of tarmac(painted or not)and rubber you will find by just using water alone via a FSC there will be overlapping stripes from where you misjudged meeting up with the FSC. Pre spraying can prevent this.
The last thing you want when it's dry is hundreds of cleaner stripes showing.

Ok fair enough - depends on surface im guessing?.
As i understand it = for a porous macadam surface - i would need to FSC it first then wash down with lance (turbo, red / white etc. nozzle????).
For a surface like tarmac or fine concrete (or are you suggesting macadam as well Blast Away?) - I can just use a FSC to remove the moss / algae (after pre spraying it with moss remover - where can i get hypo and how long does it take to work?)??
Also with regard to FSC - do the jets need recallobrating every once in a while - as i used mine last week and it seemed to take a lot longer than it should have?
What about brick paving / block paving / york stone etc. - i have generally found more satisfying results with a turbo lance - would it be better to just seek a better FSC??
Thanks for your suggestions and advice,
Rob

I don't know where you'd get it local to you. I get mine only 5 miles away from me. You'd be better off hoping someone local to you see's this and helps you out.
It works very fast and how I buy it comes 14% neat. Very strong, in 25 liters and for general paving can get a good 100 liters out of the one drum.
Check your nozzles haven't moved on your FSC. If they aren't lined how they should be then you'll get rings.
FSC's wont rip up everything. A turbo will be needed on tough weed and moss etc.

Good point about using hypo, pretty much all of the courts that I have cleaned I have then coloursprayed and lined, so no need.
I will try using hypo on my next court clean as I am no longer spraying courts only cleaning them, do you apply hypo thro your pressure washer as its corrosive?
Careful using lance/turbo on porous macadam, some damage can occur.

I have done for large areas and give the pump a good flush through straight after but I wouldn't recommend it as a must to anyone. I've done it through cheap chinese pumps. For general driveways I use the backpack sprayer or mix up in flexi tub and pour.
Careful with the hypo though, I spent time in A&E after getting a pin drop in my eye from not carefully putting down the drum with the lid off.
