Services
Chimney Lining
Our patented Thermocrete B2c system creates seamless chimney linings using high-temperature refractory material. A rubber former shapes the flue while Thermocrete fills cracks and voids, creating a rifle-barrel smooth finish. Ideal for open fires, wood/gas stoves, and cookers, this solution meets BSEN:1443 standards while preserving chimney integrity without demolition.
Chimney Sealant
High-pressure spray application seals chimney cracks with acid-resistant Thermocrete sealant. Maintains flue size while creating airtight surfaces, suitable for all chimney types. Complies with Class 1 chimney standards and offers 10-year guarantees, with testing to 1,500C operational temperatures.
Stove Installation
Complete stove integration with Thermocrete-lined chimneys. OFTEC-certified engineers install and commission wood, gas, and multi-fuel stoves. Includes regulatory sign-off and draught optimisation, ensuring safe operation and compliance with current building regulations for domestic heating systems.
