Wood Burner Servicing: How Often, What’s Included, and Why It Matters
What a proper wood burner service includes
A thorough visit usually takes 1–2 hours. Combined stove service and sweep is the best value because the engineer sees the whole system.
On the stove:
Protect floors and furniture
Strip internals: baffle / throat plate, firebricks, grate, ash pan
Clean firebox, glass, and air-wash channels
Inspect and replace worn door rope and glass gaskets
Check air controls move freely and seal
Inspect welds, flue collar, and fire-cement joints
Smoke-test the appliance and flue
Confirm a working carbon monoxide alarm is in the right place
On the flue and chimney:
Sweep from stove to pot (not vacuum-only)
Inspect liner, pot, and cowl
Check draw and ventilation
Issue a sweep certificate
Cracked firebricks that still sit in place and protect the steel body are often left; crumbling bricks that expose the carcass should be replaced. Rope seals typically last 2–3 years of regular use.
Look for a HETAS-registered engineer or a sweep who also holds stove-servicing competence.
Warning signs you are overdue
Book sooner if you notice:
Smoke leaking into the room when the door is shut
Persistent black, tarry glass
Weak or lazy flames and poor heat
A strong, acrid smell after lighting
Door that no longer grips a sheet of paper in the “paper test”
Unusual noises, rattling baffles, or visible rust / cracks
Birds nesting, moss on the pot, or soot falling into the stove
What you can do between professional visits
Daily and weekly habits do more for efficiency than any single annual visit.
Burn only Ready to Burn wood with moisture under 20%. Wet wood is the main cause of creosote and dirty glass.
Empty the ash pan regularly but leave a thin insulating layer on the grate.
Clean glass with stove-glass cleaner or damp newspaper dipped in cold ash — never abrasive pads.
Keep air vents and the area around the stove clear.
Store logs away from the appliance so radiated heat cannot ignite them.
Test your carbon monoxide alarm monthly. Building Regulations require a CO alarm in the same room as a solid-fuel appliance.
