What is included?
Block paving cleaning removes moss, algae, weeds and ground-in dirt from the surface and the joints, usually with a rotary surface cleaner on a pressure washer, which cleans evenly without the stripes a hand lance leaves. A biocide treatment can be applied to slow regrowth.
- Weeds and moss removed from the joints
- Optional biocide and sealer
- Kiln-dried sand brushed in once dry (re-sanding package)
- Pre-treatment where needed
- Rotary surface clean at a pressure that will not blow out the joints

Cleaning in Portstewart: questions
How much does a block paving cleaning job cost in Portstewart?
Guide price for Portstewart: £2.50–£5 per m² including VAT, with a minimum charge for small areas.
Do you cover Portrush, Coleraine and Limavady?
Yes. We cover Portstewart and the places around it, including Portrush, Coleraine and Limavady, and the rest of County Londonderry.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
Will cleaning damage my block paving?
Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
