Leaky ventilation ducts create unnecessary heating costs and bad air. We seal your existing ventilation ducts regardless of the shape, size and material of the system without tearing up and discarding the existing ones. Of course with the latest technology of material that molds to the ventilation duct and makes it 100% tight.

Leaky ventilation ducts quickly become a costly problem when energy is lost out of the ventilation system. Many tenants also experience intrusive noise from the neighbors.

Just because your ventilation ducts are a few years old doesn’t mean you have to replace the entire system with a new one. Instead, you can make a duct seal from the inside. With our lining method, we seal your existing ventilation ducts regardless of the shape, size and duct material of the system. The sealing material is elastic and meets the fire requirements set out in the Housing Authority’s building regulations for im ducts. All angles in the ventilation system are effectively sealed and the duct will be like new again.
