DECKING & TIMBER
Timber and composite decking need a considered method. Learn about gentle cleaning, existing coatings, board condition and realistic results.

Timber and composite decking may look robust but aggressive pressure can roughen wood fibres, damage coatings and force water into vulnerable areas. A suitable cleaning process often calls for gentler methods.
We look at the material, surface coatings, visible deterioration and manufacturer guidance before deciding whether cleaning is appropriate. Not every decking surface is suitable for pressure washing.
Tell us approximately how large the area is, what it is made of, how it is accessed and whether there are stains, loose joints or existing coatings. Photographs can be arranged separately if needed.
Sometimes at carefully controlled pressure, but many surfaces are better cleaned by a gentler method.
Ageing, UV changes and worn finishes cannot be reversed by cleaning alone.
These are separate treatments and should only be treated as available if agreed in your quotation.
Timber decking is vulnerable to raised grain, splintering and water driven into damaged boards. Composite decking has its own manufacturer-specific cleaning requirements. Neither should automatically receive the same pressure setting used for hard paving.
Timber species, existing treatments and board age all influence the approach. A gentle, controlled clean may be suitable, but high-pressure jets can damage fibres, strip soft areas and leave a patchy finish. Soundness of the boards comes first.
Composite products vary widely by manufacturer. Surface coatings, capped boards and textured finishes may react differently to heat, chemicals and nozzles. The product guidance should be checked wherever available.
Decking steps and edges often carry a greater risk of wear. Loose boards, protruding fixings or failing handrails are repair matters and should be identified before cleaning rather than concealed by the finished appearance.
A clean can lift general grime and biological build-up, but it cannot reverse rotten timber, warped boards, deep splits or fading caused by sunlight. Some marks are part of the weathering of the material.
Please tell us whether the deck has been oiled, painted or stained, how long the finish has been in place, and whether any boards feel soft or unstable underfoot. Clear photographs help identify whether a cautious inspection is appropriate.
Re-oiling, staining or surface repairs are separate activities. The deck must be in a suitable condition and dry enough for any subsequent finish, in line with the manufacturer’s directions.
Not necessarily. Ageing, sun damage and old treatments can remain visible even when surface dirt is removed.
It depends on the manufacturer and condition. Some products specifically restrict pressure or nozzle types; those instructions take priority.
Share the property postcode, the surface material and a short description. We will review the enquiry before confirming availability.
