I think that I am at the other end of the scale to most people looking at pressure washing as add ons. As some will remember I sold a very succesful window cleaning business to concentrate on pressure washing.
How did it pan out for me - I have had a difficult year financially but am now back on track, I have been very busy throughout the year with continual jobs, Islington - end of last year into january this year, from there straight to a store clean in Bath, till May. From there straight to a store clean in Cobham, from there to Beeston - store clean with drain jetting, from there to Haverhill - store clean with drain jetting, started a store clean in Newbury and am starting two more in Kent this month.
I have also picked up another high profile supermarket that are having pressure washing jobs done by my company, one in Upminster, next week one to do in Oxsted and then back to Newbury and another clean for the new client!!
These are large works and they incorporate multiple services, elevated and low level and can be weeks of pressure washing at a time.
I do some residential window cleaning (buildng a nice little round up again) but am also looking into a vacuum recovery loop system for pressure washing and have the potential of works at Heathrow airport and this will be pressure washing.
If you invest in your pressure washing side of the business and do it well you can have a very good business. There is a massive amount of cleaning out there and we are coming out of a very deep recession, people will be spending their money again. Be ready for it, the next ten to fifteen years should see returns for initial investment and hard work over the difficult times
Good luck
