Tech Duct

At Tech Duct, we deliver specialist testing, installation, and ongoing maintenance of fire dampers for both commercial and residential properties across the south of England. With over 30 years of hands-on experience installing ductwork, our team brings deep technical expertise to every project. Our work is built on compliance, safety, and reliability, giving property owners the assurance they need to meet all legal fire safety requirements with confidence.

Our services include comprehensive fire damper surveying using advanced technology to evaluate condition and performance, ensuring accuracy regardless of location. We provide detailed reports with recommendations for remedial work. Crucially, we perform fire damper drop testing to verify their proper closure in fire events, preventing the spread of flames or smoke and keeping occupants and buildings safe.

If dampers fail a drop test, we efficiently repair or replace them. We also address common issues such as broken or corroded coil springs, often found in environments like leisure centres or swimming pools due to chemical exposure. In many cases, these can be rectified in situ, avoiding costly and time-consuming full replacements.

We also highlight the importance of using only manufacturer-approved fixings, advising against the use of tek screws which can obstruct damper blades and compromise fire-resistance ratings.
