Cleaning block paving

[tlg]

I had a block paved drive done a couple of years ago, it is now starting to look very dirty and I am struggling to get it clean.

Every time I try to clean it using either a bucket of soapy water and a brush or a jet wash (with paving attachment) I just end up moving the jointing sand around and it looks just as dirty. Some area's could do with re-sanding but if I add more sand it will just go all over the drive even more.

Is there a solution to cleaning block paving without affecting the jointing sand?

I am considering getting a professional in now who will charge £120 for cleaning or £400 for cleaning, resanding and sealing (40 sqm), would this be my best option?

As always your help and advice is appreciated.

A professional will still wash the sand out. You need to develop a technique as you jet the blocks, try holding the spray at an angle. You will need to bin the old sand, as it will be full of silt. You won't be able to seal the drive until it is 100% dry, that could take weeks with the weather we've been having.

Blocks look lovely for the first 12-18mths then soon start to look shabby unless they are in the right location.

Those prices are not to bad really, but I would find out what product they are going to seal with though
