Cowls and caps serve multiple purposes: they prevent rainwater, birds, and debris from entering the chimney, improve airflow, and reduce downdraught. If your chimney is open, unused, or poorly ventilated, installing a suitable cowl or cap can protect your home and prolong the chimney’s life.

We assess your chimney’s usage and recommend the right type of cowl or cap — whether that’s for an active flue, a disused stack, or to improve airflow. Using our cherry picker, we access the chimney safely and fit the cowl securely to the pot using stainless steel straps, fixings, or clamp systems, depending on the type.
