FAQ's
Frequently Asked Questions?
Will the high-velocity water streams wash out the jointing mortar between my patio slabs?
Our technicians adjust water pressures and angles carefully based on the condition of your paving, protecting stable mortar lines while using specialized tools to clean fragile areas safely.
How long should I wait before driving on my block paving after a deep wash and re-sanding?
You can walk on the paving immediately, but we recommend waiting 24 hours before driving vehicles onto re-sanded block paving to allow the new jointing sand to settle completely.
Can professional hot-water jet washing entirely remove dark engine oil stains?
While old, weathered oil leaks that have deeply penetrated concrete can leave faint shadows, our industrial hot-water washes combined with specialized degreasers lift the vast majority of surface oil stains.
Do you replace the jointing sand that gets washed out of block paving?
Yes. As part of our complete block paving package, we return on a dry day following the wash to brush premium, kiln-dried jointing sand back into the paving joints to keep the blocks locked.
Is it safe to apply power washing treatments to domestic tarmac driveways?
Tarmac requires specialized handling. We use low-pressure settings combined with broad surface cleaners to wash tarmac driveways safely without breaking up the structural tar binders.
