• Cowl is fitted either by slipping into the flue or fixing with straps and adhesive (depending on the manufacturer guidelines)
• The fit-out is checked for safe mounting and correct ventilation

Do you need scaffolding to fit a chimney cowl?

You don’t always need scaffolding. For many single-storey or easily accessible roofs, a ladder and roof-access method might do the trick.

However, for taller properties or difficult to reach roofs, scaffolding is needed.

Tip: Make sure to ask your fitter ahead of time whether scaffolding is needed and whether the costs will be included in their quote.
