Block paving cleaning in Keighley
Fading colour, weedy joints and lost sand on clay or concrete block.
The clay-red block laid across Keighley's 90s and 00s estates picks up moss faster than newer concrete block — the porosity is the giveaway.
We work Keighley and the surrounding BD21 postcodes every week, so a Block paving job here is a scheduled call, not a special trip.
How we clean block paving
walk the drive and mark any sunken tracking or lifted blocks for prior levelling
biocide pre-treat 24 hours before wash so root moss dies below the surface
rotary flat-surface clean at fixed distance for even pigment recovery
hand-lance the edges, thresholds and around drainage points
brush in fresh kiln-dried sand across the whole area and compact
Defining traits in Keighley
- kiln-dried sand jointing that locks each block against its neighbour
- surface pigment fired or through-cast into the block face
- chamfered edges that highlight lost joint sand once weathered
- individual clay or concrete units laid on a sharp-sand bed
What ruins block paving in BD21
- 1over-pressure blows the jointing sand out and lets blocks rock
- 2leaving joints empty invites weeds and lets water track under the sub-base
- 3wrong-angle lance strips the pigment layer and leaves pale banding
When to book
Best April to October so the biocide has 24 dry hours to work and the fresh sand can bed down before rain.
Typical use: driveways, front paths, commercial forecourts, car park bays.
What we use, and why
Low-concentration sodium hypochlorite biocide first, then plain hot water through the rotary — no acid washes on concrete block, ever.
Keeping it right
Keep the jointing topped up every 2–3 years, brush leaves off in autumn, and re-treat lightly with biocide on shaded elevations.

Keighley Block paving FAQs
- Insured and DBS-checked?
- Fully insured, family-run, based in Baildon — happy to send certificates before we book.
- Do you seal after cleaning?
- Only if you want a satin or matt finish — sealing isn't automatic on block, and we'll walk you through the trade-offs first.
- Will you blow the jointing sand out of my Keighley drive?
- No — we run the rotary at a fixed head height so the wash doesn't strip the joints, then re-sand the whole area at the end.
- Do you work through winter in Keighley?
- We work all year but the biocide needs a dry 24-hour window, so we schedule around forecasts on shaded industrial town drives.
- How long does a BD21 block-paving clean take?
- A standard two-car drive is a day including the biocide pre-treat the day before.
The right result in BD21 is a drive that sheds water evenly and doesn't green up again by the next autumn.
