Getting your chimney properly sealed ensures your home stays warm and cozy while protecting it from potential damage. By sealing your chimney, you can prevent drafts and leaks, and even reduce energy bills. With the windy and wet weather that we have in Ireland, it’s no wonder that people who don’t use an old chimney decide to get it sealed. Other than the elements, birds will often nest in an unused chimney and they might even enter the house from it.

Sealing a gap in a chimney typically involves using a specialized sealant or chimney caulk to fill in any openings. It's best to hire a professional chimney sealer to ensure the job is done correctly and safely.

To prevent birds from nesting in your chimney and causing potential dangers, it is recommended to install a bird guard cowl. This metal or wire mesh cover prevents birds from entering your chimney, while allowing proper ventilation. A professional can install the cowl or remove any existing nests in a safe manner. Keep in mind that removing nests during the bird nesting season may not be allowed in some counties, so it's best to check your local legislation before taking any action.

While it is technically possible to block a chimney from the inside, it is not recommended due to the potential hazards that can arise. Blocking a chimney can lead to the accumulation of dangerous gases and fumes, as well as water damage and mold. It's best to consult with a professional and consider alternatives such as a chimney cowl or other types of coverings.

No, you do not need to seal up the entire chimney if you are putting in a fake coal fire. Instead, you can add a ventilated chimney cap on top to maintain the existing chimney. The cap will protect the chimney against water and dampness ingression and reduce heat loss. We recommend consulting with a professional to determine the extent of modifications required.
