Composite decking · Keighley BD21

Keighley composite deck care — BD21

Film build-up, mould spotting and grip loss on composite boards.

Composite decks in Keighley still get a biological film — the marketing says 'no maintenance' and the shaded corner disagrees.

We work Keighley and the surrounding BD21 postcodes every week, so a Composite decking job here is a scheduled call, not a special trip.

What composite decking actually is

Defining traits in Keighley

Where it goes wrong

Our process

Step 1

sweep board gaps clear so water and cleaner can drain

Step 2

soft-wash with a composite-safe cleaner and low-pressure rinse

Step 3

brush along the manufactured grain to lift the biological film

Step 4

clean-water rinse and dry with no residue left behind

Chemistry

Composite-safe neutral cleaner plus a low-concentration biocide on shaded runs — no aggressive alkalis, no hot rotary passes.

Timing

Any month — composite handles cold cleaning fine; dry conditions just give a nicer finish.

Typical use: new-build decks, hot-tub surrounds, roof terraces, premium garden rooms.

Aftercare

Sweep monthly, keep planters off the boards, and give the whole deck a soft-wash every 12–18 months in shaded gardens.

Is composite really 'no maintenance' in Keighley?: It's lower maintenance than softwood, not zero — shaded corners still form biofilm and need a soft-wash every 12–18 months.
Do you clean commercial composite decks?: Yes — hospitality and roof-terrace jobs in BD21 on scheduled maintenance windows.
Insured?: Fully insured, family-run, based in Baildon — certificates on request for Keighley bookings.
Is the biocide safe around a hot tub?: Yes at working dilution with a full rinse — we ask you to keep the hot tub covered during treatment.
Do you re-oil composite?: No — composite doesn't take oil. Anyone selling that on BD21 composite is either mistaken or upselling.
