Disused chimneys that lack a chimney cap or chimney pot cap are particularly vulnerable to various environmental factors, including nesting birds, air-borne debris, and adverse weather conditions. As a result, heat loss from the home can occur, leading to a significant waste of energy and expensive energy bills. Fortunately, installing chimney covers or chimney pot caps can offer an immediate solution to these issues and save homeowners money in the long run.

Terracotta chimney cowls or caps are popular solutions that can be easily installed by a local chimney sweep or contractor with the necessary expertise and equipment for roof access. The c-cap chimney covers are designed to fit standard round pots and offer 100% protection while allowing essential trickle ventilation of the flue and minimizing heat loss.

These chimney pot caps come in two sizes, with the smaller size featuring an optional insect screen for added protection against swarming bees. The caps are constructed from tough, UV-resistant thermoplastic and are injection-moulded, providing a durable, long-lasting solution at an affordable price.

The chimney covers are held securely in place on the pot with galvanized steel spring wires and take only seconds to fit. Their aesthetically pleasing design complements the traditional appearance of the chimney. By installing these chimney covers or chimney pot caps, homeowners can safeguard their chimneys from the elements and reduce expensive heat loss. They can also benefit from improved ventilation and reduced risks of unwanted intrusions from insects and nesting birds.

    Perfect solution for my unused open chimneys now not being used. Good tight fit inside the chimney liner and looks tidy from the outside. Easy to fit with a bit of brute force.

    Ordered C caps from national chimney components and they arrived within a couple of days. The caps are well made and robust and fitted easily. There's lots of adjustment due to spring clip design and you can bend the clips a little to fit the internal diameter of your chimney perfectly. Great product and looks good when fitted.

    C caps

    Posted by Guy Williams on 4th Sep 2020

    Simple to fit although the wires require a bit of convincing to go in initially and if you're pots are cracked or weak they will need binding or replacing as instructed or you may find you bust them. Once in and pushed down they fitted snug and secure. They look good and the amount of draw at the fireplace is noticeably less which should help with heat loss. No more dead birds too. Good product, arrived quickly and doing the job.

    Chimney Cap

    Posted by mo on 6th Jun 2020

    I had a pigeon that fell down my chimney and realised that it had to be sealed. Initially I was surprises that two of the caps did not fit the pots. I was pleasantly surprised that the cap wire meant it was sealed onto the pot and thus solved my problem.

    Ideal lightweight product for sealing diss-used chimneys.

    The caps were easy to assemble and the man who fitted them completed the job in a matter of seconds for each cap. Although 8 were purchased two were not used but it was not possible to see this from ground level. The fitter said they were easy to fit.
