Installing a chimney cap

There are many types of chimney caps. They are used to avoid pests, debris and dirt from infiltrating into the chimney.

Screw tightening

If you are using a single-flue chimney cap, you just have to put it into place and, using a screwdriver, properly fasten it.rclma The screws will surely loosen over time because of wind and rain, so it’s important that you inspect the cap often and tighten the screws when needed. Any damaged parts of the cap must be replaced. High quality screws and components are recommended.

Securing caps on tile flues

To properly secure a chimney cap into place, you can use screw or nuts and cap sealant. For the inside of the caps, use a silicone based sealer.

Securing caps on metal flues

You must use a heat resistant sealant when working with caps and a metal flue, because metal heats up more rapidly and can melt the adhesive. A thick layer of sealant must be applied to the surrounding area of the cap using a caulking gun. For the best results, after applying the sealant press on the cap and smooth any extra sealant to stop it from oozing later.
