Hi,
We used to do loads of this type of work all across where you operate Richy. The general trend over the last couple of years is for the bricklaying contractors to pick this up as part of their package, rather than getting a cleaning contractor to do it. Probably a cost saving exercise from the developer.
Also, I recently spoke to a guy who runs a large outfit specialising in pressure washing new build construction who told me that the NHBC are looking to ban jet washing to new properties because of damage to pointing and bricks! Apparently they are looking to bring the policy in over the next few years.
How this will work I don't know, because some properties are caked in snots and render, and the developer won't be able to present the plot in such a condition.
Cheers,
Huw.
