Depending on the size of your specific flue, ensure that it is covered by 1-3 inches; create at least five inches between the top edge of your chimney flue and its lid for more efficient airflow; then secure all sides firmly using screws.

Installing a chimney cap with a friction fit may sound easy, but it can be quite the challenge. That’s why we recommend you get in touch with an experienced chimney technician instead of trying to do-it-yourself! Make sure that whatever parts are used have been approved for use on your particular model – stick to original manufacturer items if you’re able, otherwise consult an expert and stay safe!

When installing your new chimney cap, make sure that the cap is secured tightly in its metal flue before using silicone sealer to secure it and keep things tight. And if two or more pipes are arranged concentrically – commonly called air-cooled flues? You’ll need a special type of cap so cooling air flows properly from pipe to pipe. Don’t forget, it is always best to use manufacturer chimney parts

Multi-flue caps are the ultimate challenge in chimney cap installation! These covers not only span across the entire chimney crown, but need to be perfectly drilled and mounted into place—or they could easily fly away. Thankfully, these bad boys come with a diverse selection of styles that add character to any chimney—just as long as you don’t skimp on precision when putting it up.

If you’re thinking of going DIY for your chimney cap replacement, just remember: it may seem straightforward at first glance but there’s a very real risk that things can go wrong. From caps blowing off to further damage down the track – if in doubt call an expert! Many happy homeowners prefer to bundle their chimney cleaning and cap-changing into one neat package so they don’t have anything to stress about
