Block paving cleaning in Harrow: the local picture
Harrow has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Front gardens in much of London are short, so parking depth and the dropped kerb usually decide whether a drive is possible.

What does a block paving cleaning job involve?
Cleaning washes out some of the jointing sand, so a proper clean is followed by re-sanding with kiln-dried sand once the surface has dried. Many owners then seal the paving to lock the new sand in and keep it cleaner for longer.
- Pre-treatment where needed
- Rinse down of edges, steps and walls
- Optional biocide and sealer
- Weeds and moss removed from the joints
- Rotary surface clean at a pressure that will not blow out the joints
How we find the cause
- Moss, algae, weeds and oil staining
- Walls, doors and planting to protect
- Which sealer finish suits a slope or patio
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Type of block and its age

Cleaning in Harrow: questions
How much does a block paving cleaning job cost in Harrow?
Guide price for Harrow: £3–£6 per m² including VAT, with a minimum charge for small areas.
Do you cover Brent, Greenford and Ruislip?
Yes. We cover Harrow and the places around it, including Brent, Greenford and Ruislip, and the rest of Greater London.
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.
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.
