Sweeping and Inspections Across Gwynedd's Rural Neighbourhoods

All seven sweeps based in Gwynedd cover rural parts of the county, serving villages and hamlets from Llanllyfni and Rachub in the north to Llandderfel in the south. Most carry out standard chimney sweeping, and many offer CCTV camera inspections so you can see inside your flue without guesswork. If you have a wood burner, stove or Aga, ask whether they offer annual servicing packages. A smoke or draw test costs £35 to £65 and confirms that your fire is drawing properly and safely.

Four of the seven sweeps work Saturdays, which can be useful if you need a visit fitted around weekday commitments. When you call or email, mention your appliance type (open fire, wood burner, range cooker, multi-fuel) so they can quote accurately and bring the right equipment.

Open fire sweep: £55 to £85; wood burner or stove: £60 to £90
CCTV inspection: £85 to £140 to check for blockages, creosote or damage
Smoke test: £35 to £65 to verify draw and air flow
Second flue on same visit: £30 to £45 if you have multiple appliances

Repairs, Fittings and Specialist Work in Gwynedd

Beyond routine sweeping, sweeps in Gwynedd can handle bird guard and cowl installation (£65 to £140), removal of nests that are not protected by law, chimney pot replacement and stack repointing. If your flue is damaged or your chimney is poor for drawing, a flexible flue liner (£835 to £2,045 fitted) can often restore function. Power sweeping with a rotary brush (£85 to £140) tackles heavy tar buildup in older chimneys where creosote has accumulated over years.

Work at height on exposed rural properties needs care and insurance. All legitimate sweeps carry public liability cover, and many hold qualifications from HETAS or trade bodies like NACS or the Guild of Master Sweeps. Ask to see their insurance certificate and sweeping credentials before work starts.

How often should I sweep my chimney in Gwynedd?

Sweep an open fire once a year at minimum, and more often if you use it heavily. Wood burners and stoves should be swept annually too, or twice yearly if you burn a lot of wood. If you use an Aga or range cooker, sweep the flue annually before winter. Most sweeps recommend autumn sweeping, but spring is a good time to check for blockages or damage from the previous season.

What does a CCTV chimney inspection show?

A CCTV inspection (£85 to £140) lets the sweep see inside your flue without mess or guesswork. It reveals creosote buildup, blockages, bird nests, cracks in the flue lining, collapsed mortar, or debris. If a problem is found, the sweep can advise on repairs, or a new flue liner. It's especially useful if you've just bought a property or haven't swept in years.

Can a chimney sweep remove a bird nest?

Yes, sweeps can remove nests once the breeding season ends (usually August onwards). Nests with eggs or chicks are protected by law, so removal must wait. If you find an active nest, ask your sweep to call back in late summer or fit a bird guard (£65 to £140) once the birds have left.

What is a chimney sweep certificate and why do I need one?

A sweep certificate (or chimney sweep record) documents that your chimney has been professionally cleaned and is safe to use. You should get one after every sweep. It's useful for your insurance and for proving maintenance if you sell your home. Make sure your sweep is insured and qualified, look for HETAS or Guild of Master Sweeps membership.

How much does a flue liner cost in Gwynedd?

A flexible flue liner, supply and fit, costs £835 to £2,045 depending on the chimney height, diameter and any bends. It's used when the original flue is cracked, too narrow, or poorly constructed for your appliance. The sweep will assess your chimney before quoting. A smoke test (£35 to £65) can sometimes show whether a liner is needed.

Why should I book my chimney sweep in summer?

Booking in May to August lets you avoid the September to December rush when many households need sweeping before winter. Summer appointments are easier to arrange, and you'll know your chimney is clear and safe before the heating season starts. If you wait until October, you risk a longer wait for an available slot.
