Cladding has become a common way to finish extensions, garden rooms and refreshed elevations across Kent, and cedar and composite are the two materials asked about most. The decision genuinely comes down to whether you want a material that has a life of its own.
How each one ages
Cedar starts a warm honey-brown and silvers to a soft grey over a few years of weathering, a process that happens unevenly depending on sun and rain exposure across the elevation. This is not a defect — it is what untreated cedar does, and most people who choose it are choosing that look deliberately.
Composite cladding is manufactured to a fixed colour and stays close to that colour for a long service life, with UV-stable formulations resisting fade far better than painted timber ever did.
Maintenance and repair
Cedar left to silver naturally needs almost no maintenance beyond occasional cleaning, though if the intention is to preserve the original colour rather than let it silver, that requires a UV-stable oil reapplied periodically. Damaged boards are repairable individually, matching the surrounding weathering by eye.
Composite needs essentially no maintenance cycle at all, and damaged boards are also replaceable individually, but colour matching an older installation can be harder if the specific product range has changed since the original installation.
Where each suits the elevation
Cedar tends to suit contemporary extensions and garden buildings where a natural, evolving material reads as an asset, and period properties where a traditional weatherboard character is wanted.
Composite suits exposed elevations, north-facing walls that never get sun to weather evenly, and situations where consistent appearance matters more than natural material character — rental properties and commercial fronts are common examples.
What drives the cost of either system
Cedar cladding cost tracks the grade and width of board chosen, and whether it is factory pre-finished with a UV-stable oil or left to be finished or silvered naturally, which affects labour but not material cost.
Composite cladding cost tracks the specific product range and profile, and installation labour is broadly similar to timber since both are typically fixed to a batten frame with a ventilated void behind.
Access and the batten frame underneath
Both materials are fixed to a treated timber or aluminium batten frame set out from the wall to create a ventilated cavity, and that frame — not the visible cladding — is what determines how the wall behind is protected from moisture.
A written quote for either material should specify the batten frame's material and fixing method, the cavity depth, and how the cavity is closed at the top and bottom to keep pests and debris out while still allowing airflow.
Common questions
Does cedar rot if left unfinished?+
Cedar is naturally durable and resists decay well even left untreated, provided it is detailed correctly with ventilation behind the boards and no standing water traps at the base. It is the detailing, not the lack of finish, that causes problems.
Is composite cladding recyclable?+
This varies by product and manufacturer — some composite ranges include recycled content and are recyclable at end of life, others are not. It is worth asking the specific manufacturer's data rather than assuming either way.
Can I mix cedar and composite on the same building?+
Yes, and it is sometimes done deliberately — cedar on a sheltered, sun-facing elevation that will weather evenly, composite on an exposed or shaded elevation where uneven weathering would look patchy.
