Services
Chimney Sweeping
Our chimney sweeping service removes flammable creosote and soot buildup to prevent chimney fires and ensure safe operation. We use rotary and traditional methods for domestic and commercial chimneys up to 150 feet tall. All sweeps include a smoke draw test and insurance-approved certification.
Creosote Removal
We specialise in removing hazardous creosote deposits using the Cre-Away Pro dry powder method. This non-corrosive solution transforms hardened creosote into sweepable residue over 2-4 weeks, avoiding costly chimney relining while maintaining structural integrity.
Biomass Servicing
Our biomass boiler servicing includes flue gas analysis up to 100,000ppm CO and draught measurement. We use specialist equipment to maintain efficiency and safety in solid fuel biomass installations, ensuring compliance with EN 1443 standards for commercial and residential properties.
Chimney Camera Surveys
We conduct detailed chimney integrity tests using DP23 pressure equipment to detect leaks and structural issues. The survey includes flue dimension analysis, leakage rate calculation, and printed compliance reports to determine if relining is required.
Bird Guard Installation
Our bird and squirrel guards prevent nesting in chimneys, reducing carbon monoxide risks and hygiene hazards. We also install anti-downdraught cowls and breather caps to stop heat loss while maintaining chimney ventilation for disused flues.
Questions
What areas do you cover?
We operate across London, Havering, and South Essex, including North, West, and Central London. Emergency callouts may extend to surrounding regions during severe weather.
How often should chimneys be swept?
Frequency depends on fuel type: wood (seasonal), smokeless coal (yearly), bituminous coal (twice yearly), and gas/oil (yearly). Certificates require documented maintenance.
Do you offer emergency services?
While our standard hours are 9am-5pm Mon-Fri, we prioritise urgent cases like blocked flues causing carbon monoxide risks. Subcontractors handle emergencies outside normal hours.
Can you service biomass boilers?
Yes, our engineers use Wohler analysers capable of 100,000ppm CO measurement, exceeding standard equipment capabilities for safe biomass boiler maintenance.
How do you test chimney integrity?
We use the DP23 pressure test machine to measure leakage rates against EN 1443 standards, providing printed pass/fail results instead of outdated smoke tests with subjective outcomes.
What payment methods do you accept?
We accept cash, bank transfers, and major credit/debit cards for all services. Payment terms for commercial contracts are available upon request.
