Most homeowners book a chimney sweep and assume they’ve done all the maintenance their wood-burner needs. The sweep is essential — but it only covers the flue. The stove itself is a separate appliance with its own wear parts, and most of them are working at temperatures above 400°C every winter evening. They wear out. When they wear out, the stove burns less efficiently, the glass goes black faster, and in some cases the safety of the appliance is affected.

This is what a proper annual wood-burning stove service should cover — whether we’re doing it for you in Newcastle, Sunderland, Durham or anywhere across the North East, or whether you’re booking someone else.

Why an annual stove service matters

Safety

A stove with a worn door rope, a cracked fire brick or a dropped baffle plate isn’t just inefficient — it can be unsafe. Worn door seals let air in where it shouldn’t, which changes the burn pattern. A cracked fire brick exposes the steel body of the stove to direct flame. A baffle plate that’s slumped can block the flue exit and push smoke back into the room.

Efficiency & running cost

A well-maintained Ecodesign stove can run at 75–85% efficiency. A neglected one drops below 60% — meaning more wood burnt for less heat. Over a North East winter, that’s a meaningful amount of money disappearing up the chimney.

Manufacturer warranty

Most stove manufacturers (Stovax, Charnwood, Clearview, Morso, ESSE and others) require evidence of annual servicing for warranty claims. If a structural component fails and you can’t show you’ve maintained the appliance, the warranty may not honour the claim.

The full service checklist

Here’s what we check on every stove service:

1. Door rope seal

The rope (or tape) gasket around the door is what creates the airtight seal that controls combustion. Over a season it compresses, hardens, and eventually fails. Test: close the door on a piece of paper — if you can pull the paper out without resistance, the rope is gone. Replacement is a 15-minute job and costs £15–£25 in parts. We replace it as part of the service.

2. Glass gasket

The flat gasket between the glass and the door frame is the most common cause of cracked glass — if it’s missing or hardened, the glass can move under thermal stress and crack. Check during service, replace if hardening.

3. Fire bricks (vermiculite or refractory)

The bricks lining the firebox protect the steel body and reflect heat back into the burn. They’re sacrificial — they crack, crumble and need replacing. Small hairline cracks are normal. Anything where pieces are missing, falling out, or the steel behind is visible needs replacement.

4. Baffle plate (throat plate)

The horizontal plate at the top of the firebox is what forces hot gases to circulate before they exit the flue. It warps, sags, and on some models eventually drops. A missing or fallen baffle is a serious efficiency and safety issue. Check that it’s seated correctly, isn’t warped, and isn’t resting on top of the fire bricks.

5. Air vents and controls

Primary, secondary and tertiary air controls all need to operate smoothly. Soot and ash work into the sliders and pivots over time. Clean, check movement, lubricate where needed.

6. Airwash function

The airwash system blows clean air down across the glass to keep it clear. A blocked or restricted airwash channel is why your glass goes black after 20 minutes. Clean the airwash inlet, check the path.

7. Flue draw test

Smoke pellet test to confirm the chimney is drawing. Done as part of the chimney sweep but worth re-checking after any stove work.

8. External condition

Body of the stove, flue collar, register plate, hearth, surround. Check for cracks, corrosion, signs of overheating (warped metal, blistered paint), correct hearth clearance, correct combustible clearance to surrounds.

9. Carbon monoxide alarm

We check that you have one, it’s working, it’s in the right place, and it’s not past its battery or sensor expiry. If you don’t have one, we’ll tell you.

What should be replaced vs cleaned

The honest answer: it depends what we find.

• Always cleaned: firebox, ash pan area, air vent channels, airwash inlet, flue collar.
• Always tested: door seal, glass seal, baffle plate seating, controls movement, flue draw.
• Replaced if worn: rope seal (often annually), glass gasket (every 2–3 years), fire bricks (when cracked through), baffle plate (when warped or burnt through), handle springs (when failing).

We don’t replace parts that don’t need replacing. If your door rope is still tight, we leave it. If your fire bricks are intact, we leave them. We’ll always show you what we find before we replace anything significant.

Cost expectations in the North East

A standalone annual stove service runs £90–£140 in the North East depending on the appliance, plus parts if anything needs replacing. Combined with a chimney sweep on the same visit, expect £130–£180 total for the pair. Compare that to running an inefficient stove all winter — or replacing one that’s failed prematurely — and the maths is generous.

DIY vs professional service

Some of the work above — ash clearance, glass cleaning, basic visual inspection — you can absolutely do yourself, and we encourage owners to know their appliance. But the bits that matter for safety and warranty — door seal pressure testing, baffle plate condition, fire brick assessment, flue draw testing, replacement parts to the right spec for your specific stove model — really do benefit from someone who’s done it on a few hundred stoves.

The other reason: most stove warranties require evidence of professional servicing specifically. A self-service log usually doesn’t count.

When to book

Spring or late summer, before the autumn rush. Most North East owners light their stove for the first time in October. By then everyone’s booking, and the parts (specific to your stove model) can take a few days to arrive. May–August is the calm window — service done, parts replaced, no rush.
