How to Fix Timber Cladding

Updated April 17, 2017

Timber--often cedar--is a popular choice of siding on account of its excellent aesthetic qualities and natural resistance to inclement weather. However, if poorly maintained, the cladding--or siding, as it is often called--can decay over time. Knowing how to fix, repair and maintain your cladding will mean that it remains attractive and durable for years to come.

Wash the cedar siding with mild detergent and scrub it with the brush to remove any debris, dirt and mould.

Rinse the siding with a garden hose to remove any traces of the detergent.

Spray the cladding using your power sprayer, remembering to keep the top of the nozzle at least 30 inches away to prevent damage.

Inspect the cladding for any loose or broken areas. Cut off any damaged areas carefully.

Cut a new piece of siding to fit the gap left behind by the section you have just removed. Nail it into place using galvanised nails, to prevent rusting. Use a utility knife to cut pieces for small areas.

Treat the new piece of siding with a UV blocker sealant to prevent the wood from turning grey over time.
