Product Description

Reeds Capping Cowl for Disused Chimney Pots Terracotta

Part Number: 19-03010302

Protect a redundant chimney with the Reeds Capping Cowl for Disused Chimney Pots. This terracotta-coloured chimney cap helps stop rain, birds, leaves and other debris from entering an unused flue.

Although the cowl covers the top of the chimney pot, its design still allows air to move through the redundant chimney. As a result, it helps reduce trapped moisture and the risk of damp developing inside an unventilated flue.

The cowl fits suitable chimney pots measuring approximately 200–250mm (8–10 inches). In addition, it includes a strap fixing kit to secure it around the chimney pot.

Important: This capping cowl is only for a disused chimney. Do not fit it to a working flue or a chimney connected to an appliance.

What Is a Chimney Capping Cowl?

A chimney capping cowl covers the top of a redundant chimney pot. It helps stop rain, birds, leaves and debris from falling directly into the unused flue.

However, a redundant chimney should not always be sealed without ventilation. Moisture can remain trapped inside the chimney if air cannot move through it.

For this reason, the Reeds capping cowl retains airflow while covering the pot. Therefore, it provides a better solution than completely sealing the chimney with an unventilated cover.

Suitable for Disused Chimneys Only

This product is designed for a chimney that no longer serves a fire, stove, boiler or other heating appliance.

Do not use this cowl on an active flue. Its capped design does not provide a suitable outlet for combustion gases.

Before installation, confirm that no appliance connects to the chimney. If you are unsure, ask a chimney professional to inspect the complete flue.

Helps Stop Rain Entry

An open chimney pot allows rain to fall directly into the flue. Over time, this water may contribute to damp patches, damaged mortar and staining around the chimney breast.

The capping plate covers the top opening and helps deflect rainfall away from the chimney. However, wind-driven rain may still reach exposed parts of the pot and stack.

Therefore, inspect the chimney stack, flashing, pointing and pot before fitting the cowl. The cowl cannot repair existing building defects.

Helps Prevent Bird and Debris Entry

Open chimney pots may allow birds, leaves and other debris to enter the flue. Birds may also try to build nests inside an unused chimney.

This capping cowl closes the main opening and helps block entry. As a result, it can reduce the chance of larger debris falling into the chimney.

However, the chimney should remain clear before installation. Remove any existing nest or blockage legally and safely before capping the pot.

Maintains Chimney Ventilation

A disused chimney can contain moisture from old soot deposits, rain penetration and condensation. If the flue has no airflow, this moisture may remain trapped.

The cowl allows ventilation around the top of the redundant chimney. Therefore, air can continue to move through the flue after the pot has been capped.

For effective airflow, the chimney may also need a ventilated opening at its lower end. Ask a competent installer to check the full ventilation route.

Chimney Pot Compatibility

This cowl suits many chimney pots measuring approximately 200–250mm (8–10 inches). However, chimney pots vary in shape, wall thickness and external diameter.

Measure the pot before ordering. Also check that the fixing legs and strap can sit securely around the pot without damaging it.

Do not install the cowl on a cracked, loose or badly weathered chimney pot. Repair or replace the damaged pot first.

How Is the Cowl Secured?

The cowl uses adjustable legs and a strap fixing around the chimney pot. The installer positions the legs against the pot and then tightens the strap to hold the cowl securely.

The fixing must remain firm enough to resist wind and poor weather. However, do not overtighten the strap because excessive pressure may crack an old clay pot.

After installation, check that the cowl sits level, remains stable and does not move on the pot.

Galvanised-Steel Construction

The cowl uses galvanised steel for strength and weather resistance. In addition, its protective terracotta-coloured coating helps it blend with many traditional clay chimney pots.

Like all external metal products, the cowl will experience rain, wind, sunlight and changing temperatures. Therefore, inspect the finish and fixing strap during normal roof and chimney maintenance.

Installation Guidance

• Confirm that the chimney is fully disused
• Make sure no appliance connects to the flue
• Measure the chimney pot before ordering
• Inspect the chimney pot for cracks or movement
• Remove any existing nest, blockage or loose debris
• Check that the fixing legs sit evenly around the pot
• Position the cowl centrally over the opening
• Fit and tighten the supplied strap securely
• Do not overtighten the strap around an old clay pot
• Check that the cowl remains level and stable
• Maintain a suitable ventilation route through the redundant chimney
• Follow safe roof-access and working-at-height procedures

Installing a chimney cowl requires safe access to the roof. Therefore, we recommend using a competent chimney specialist, roofer or installer with suitable access and fall-protection equipment.

Before Capping a Chimney

Inspect and clean the chimney before fitting the cowl. Existing bird nests, fallen masonry or heavy soot deposits may block the ventilation route.

In addition, check the condition of the following areas:

• Chimney pot
• Mortar flaunching
• Chimney-stack pointing
• Roof flashing
• Internal chimney breast
• Lower ventilation opening

A capping cowl will not correct damaged masonry, failed flashing or an existing damp problem. Complete any required repairs before or during installation.

Maintenance

Inspect the cowl after severe weather and during routine roof maintenance. Make sure the strap remains tight and the cowl has not moved.

Also check that leaves, moss and other debris have not blocked the ventilation gaps. Clear any build-up carefully so air can continue to move through the chimney.

Replace the cowl if the metal, coating, fixing legs or strap becomes badly damaged or corroded.

Frequently Asked Questions

What is this capping cowl used for?

It covers the top of an unused chimney pot. It helps keep out direct rain, birds, leaves and other debris while retaining ventilation.

Can I use it on a working chimney?

No. This cowl is only for a disused chimney. Do not fit it to a flue connected to a fire, stove, boiler or other appliance.

What size chimney pot does it fit?

It fits many suitable chimney pots measuring approximately 200–250mm, or 8–10 inches. Measure the pot before ordering.

Does the cowl completely seal the chimney?

No. It covers the top opening while retaining airflow through the redundant flue. This ventilation helps reduce trapped moisture.

Will it stop rain entering the chimney?

It helps prevent direct rain from entering through the top of the pot. However, it cannot stop water entering through damaged masonry, pointing or roof flashing.

Will it stop birds entering?

It closes the main chimney-pot opening and helps stop birds from entering. Remove any existing nest legally and safely before fitting it.

Is the fixing strap included?

Yes. The cowl comes with a strap or jubilee-band fixing kit and adjustable legs.

What material is the cowl made from?

It is manufactured from galvanised steel with a protective terracotta-coloured finish.

Can I install it myself?

Only if you can work safely at roof level and have the correct access equipment. In most cases, we recommend using a competent roofer or chimney specialist.

Does a disused chimney need ventilation at the bottom?

It may need a suitable lower ventilation point to create airflow through the chimney. Ask a competent installer to assess the complete flue.

Will this cowl cure chimney damp?

It may help by reducing direct rain entry and maintaining ventilation. However, it will not repair damaged flashing, masonry, pointing or existing moisture problems.
