As industry leaders and authors of the City & Guilds qualification for chimney sweeping, we’ve heard every chimney myth imaginable. Today, we’re setting the record straight with essential chimney safety tips and debunking common misconceptions that could put your home at risk.
Myth 1: “A Chimney Fire Will Clean Your Chimney”
This dangerous myth couldn’t be further from the truth.
The Reality:
- Chimney fires can reach temperatures over 1,000°C
- They can crack or warp your chimney liner
- Structural damage often isn’t visible from the ground
- A single chimney fire can compromise your entire system
Safety Tip: Schedule regular professional sweeping to prevent creosote buildup. After any chimney fire, a professional CCTV survey is essential to assess potential damage before further use.
Myth 2: “If You Can’t See Smoke, Your Chimney is Safe”
Many homeowners believe visible smoke is the only sign of problems.
The Reality:
- Carbon monoxide is invisible and odourless
- Modern efficient fires produce less visible smoke
- Internal damage can occur without visible signs
- Some blockages won’t show obvious symptoms
Safety Tip: Install carbon monoxide detectors and schedule annual inspections regardless of visible signs. Never rely on visual indicators alone.
Myth 3: “Burning Paper Will Remove Creosote”
This old wives’ tale is not only ineffective but dangerous.
The Reality:
- Paper burns too quickly to affect creosote
- Flying burning paper can create fire hazards
- Rapid temperature changes can damage your chimney
- Creosote requires professional removal methods
Safety Tip: Only use professional chemical treatments and mechanical cleaning for creosote removal. Prevention through proper burning practices is key.
Myth 4: “Gas Fires Don’t Need Chimney Sweeping”
A common misconception about gas appliances.
The Reality:
- Gas flues can become blocked by debris
- Birds can nest in gas chimneys
- Spiders love warm gas flues and can soon block them with their cobwebs
- Condensation can cause deterioration
- Annual inspection is legally required for landlords
Safety Tip: Maintain regular inspection schedules for all fuel types. Gas fires need professional attention just like wood-burning appliances.
Myth 5: “DIY Chimney Sweeping is Just as Good”
The rise of DIY videos has led to this dangerous belief.
The Reality:
- Professional sweeps use specialised equipment
- We can identify structural issues
- Proper certification is required for insurance
- DIY methods often miss critical problems
Safety Tip: Always use certified professionals for chimney maintenance. DIY cleaning can void your home insurance and miss serious issues.

Myth 6: “Summer is the Wrong Time for Chimney Maintenance”
Many wait until autumn to think about their chimney.
The Reality:
- Summer is ideal for maintenance
- Birds often nest in spring/summer
- Soot contains acidic compounds that can erode your chimney
- Leaving soot in place all summer increases erosion damage
- Wet weather can worsen existing problems
- Early booking ensures readiness for winter
Safety Tip: Schedule your annual sweep and inspection after your last fire of the season. Don’t leave corrosive soot in your chimney throughout summer – this gives acidic deposits more time to damage your chimney’s structure. Early booking also helps you avoid the autumn rush and ensures your system is ready for winter.
Myth 7: “A Chimney Cap Prevents All Problems”
While caps are important, they’re not a complete solution.
The Reality:
- Caps primarily prevent rain and animal entry
- They don’t prevent internal deterioration
- Regular maintenance is still essential
- Some caps can restrict proper draft
Safety Tip: Install appropriate chimney caps but maintain regular professional inspections and cleaning.
