hi there,
timbob,
you might want to throw a little petrol pressure washer in your vans, worth weight in gold.
ours cost £160.00 brand new pulls from a drum or mains, and everytime we get it out its at least £60 if not more, and thats for not a lot of work really.
the developers love it, you will find that they do have their own on site but if you mention youve got one then they will usually ask you to just pressure washer the garden path, or drive, bang £60 for 30 minutes.
just an idea.
regards
martin
ps we missed out on a big tender last september £250,000 we were out by about 8%, that would have been nice, most of the stuff we do at the moments are sites about 75-150 plots.
