What is a chimney cowl?

Chimney cowls are clever metal ventilators installed above your chimney pot. They work to prevent chilly down drafts. They also stop smoke from being blown back into your living space. Chimney cowls aren’t a requirement, so adding one is completely optional.

What is the difference between a chimney cowl and a chimney cap?

**A cap** usually sits on the pot as a cover with mesh. Meanwhile, **a cowl** often has a more specific aerodynamic or fuel-type design. Both help protect from rain, down-draught and birds, but an [experienced installer](https://www.checkatrade.com/blog/chimney-cowl-fitters-near-me/) can advise which fixture suits your chimney best.

What factors affect the cost of chimney cowl installation?

The [amount you pay for a chimney cowl installation](https://www.checkatrade.com/blog/cost-guides/chimney-cap-installation-cost/) will depend on a few factors including: - **Size of chimney** - Larger chimneys will need larger cowls - **Type of cap or cowl** - **Quality of cap or cowl** - **Accessibility** - If your chimney is difficult to access, this may increase the cost of labour - **Scaffolding** - If [scaffolding ](https://www.checkatrade.com/blog/cost-guides/cost-scaffolding/)is needed to fit your chimney cowl, this will push up the cost of installation

How long does a chimney cowl last?

A quality stainless steel or aluminium cowl fitted and maintained properly should last many years. That said, weather exposure, corrosion, and roof movement can all affect the lifespan.

Do chimney cowls come with a warranty?

Many cowls and accessories often come with a standard manufacturer’s warranty of around **two years**. Your installer will be able to tell you if your new chimney cowl is covered by a warranty, and for how long.

Will fitting a cowl require me to update my chimney liner or flue?

You don’t always need to update your chimney liner or flue when fitting a cowl. However, if the fitter discovers your liner is cracked or blocked, you may need additional work.

When is the best time to fit a chimney cowl?

As soon as you notice issues like **rain ingress, downdrafts, bird nests or odours** you'll want a fitter round to take a look. It’s often easier to schedule in chimney cowl installation in the milder months, but many fitters will carry out work year-round.

Can I install the chimney cowl myself?
