Services
Chimney Lining
Our patented Thermocrete B2C lining system restores chimney functionality without invasive construction. The process involves inserting a rubber former, pumping refractory material to fill voids, then removing the former to create a smooth, durable flue. This solution addresses smoke leakage, structural damage, and compliance issues while maintaining building regulations for all fuel types.
Chimney Sealant
The Thermocrete Sealant system applies a gas-tight coating using high-pressure rotating spray technology. This environmentally friendly solution seals cracks and gaps without reducing flue size, offering 10-year guarantees. The BSEN 1443 approved treatment withstands temperatures up to 1500C, providing acid resistance and improved chimney efficiency.
Heritage Chimney Repair
Specialist restoration for listed buildings and heritage properties. Our non-invasive techniques preserve original structures while modernising functionality. Recent projects include Grade 1 listed Hardcastle Hall's 8-flue system restoration, demonstrating our capability to handle complex historical challenges while maintaining architectural integrity.
Stove Installation
Comprehensive stove installation service including OFTEC certification. We integrate new heating appliances with chimney systems, ensuring optimal performance and safety. Our engineers handle all fuel types, from traditional wood burning to modern gas systems, with complete commissioning and regulatory sign-off included.
Shared Stack Repair
Specialist solutions for shared chimney stacks requiring sensitive repairs. Our techniques allow working on individual flues without disturbing adjacent properties, as demonstrated in complex installations where neighbouring properties declined chimney disturbance during midfeather leak repairs.

Had chimney relined with Thermocrete 24 years ago, very clean process and chimney still sound after all this time. About to have another chimney relined and price quoted is very good value.
