What Is Timber Blast Cleaning?
Controlled, low-pressure blast cleaning of structural and decorative timber to remove old paint, varnish, blackening and weathering — without bruising the grain or removing the natural patina underneath.
What We Clean
Exposed Beams & Trusses
Barn & Farm Building Timber
Cladding & External Timber
Why Soda Blasting Is Often Used on Timber
Sodium bicarbonate (baking soda) media is soft, water-soluble and biodegradable. At low pressure it lifts paint and blackening out of the grain without abrading the wood underneath. Compare to a hard grit at high pressure, which permanently opens up the grain and makes the timber re-soil in a season.
Common Problems We Fix
- Old paint, varnish and stain
- Woodworm treatment preparation
- Weathering and UV bleaching
- Soot from open fires
- Blackened barn timber
- Preparation for waxing or oiling

Frequently Asked Questions
Will blast cleaning damage old timber beams?
Not if we use soda blasting at low pressure — which is our default for structural timber. Soda media is soft enough to lift paint and varnish without abrading the grain. Hard grit at high pressure would damage the timber, and we don't use it on beams.
Can you treat woodworm as part of the job?
We don't apply woodworm treatment ourselves, but soda blasting is the ideal preparation for treatment — it opens the surface cleanly so the chemical penetrates deep, without damaging the timber. We can hand the job over to a treatment specialist the same day if needed.
Is soda blasting safe for exposed structural timber?
Yes. Soda is water-soluble, biodegradable, non-toxic and gentle. It's used routinely on historic timber and doesn't compromise structural integrity. We mask surrounding stone, plaster and glass, and rinse down after so no residue is left.
