What are Historic Chimneys?

Problems to Look Out For

Freeze-thaw cycles will continue to damage until the chimney is at risk of collapse. Problems with the masonry damage to the chimney footing can also cause the structure to shift. Servicing historic chimneys will identify and fix these issues. Regular maintenance will prevent chimney damage and extend the life of the chimney.

Repointing and Repairing Mortar Joints
As you inspect your old chimney, you may find the mortar joints are weak or cracked. In old chimneys, the mortar is often lime-based and different from modern cement-based mortar. If the mortar is damaged, repointing is required. Repointing involves removing the old crumbling mortar and applying new mortar to restore the joint’s strength and integrity. Use a pointing trowel and putty knife to remove excess mortar debris and make sure the new mortar fills the joints properly. For a truly authentic old chimney restoration, make sure to use mortar that matches the original composition as closely as possible to maintain the aesthetic charm and historical integrity of the wood in your chimney.
Prevent Water Damage
Water is the biggest enemy when it comes to chimney damage. If your old chimney has a cracked roof or damaged chimney crown, water can get into the chimney system and cause damage over time. Installing a new concrete cap or repairing the roof or chimney crown with a water-repellent sealant will stop water from getting into the chimney structure. A chimney cap is also important to keep debris, smoke, rain, and animals out of your chimney. A properly installed chimney cap will stop water leaks, and keep the chimney strong for years to come.
Restore the Flue
The flue is the most critical part of the chimney system as it directs smoke, heat, and toxic gases from your fireplace or wood-burning stove safely outside. If your old chimney has a cracked or damaged flue liner, you need to address the issue as soon as possible. Flue liners made of clay, metal, or even cast-in-place materials can deteriorate over time and allow toxic gases like carbon monoxide to leak out. A damaged flue liner also increases the risk of a chimney fire, which can cause significant damage. A chimney sweep can inspect the chimney problems flue liner for damage, and a professional can recommend the repair or replacement. A flue liner replacement can take a few hours, but make sure your chimney is still safe to use.
Repair or Replace the Chimney Cap and Crown
The chimney cap and crown are there to protect your chimney from the weather. If your chimney cap is missing or damaged, it can cause water damage, rusty metal components, or animal intrusion. The chimney crown, a stainless-steel part that seals the top of the chimney, can crack over time, let water in, and damage the roof and the whole structure. To restore your old chimney properly, install a new concrete cap or chimney crown to stop water infiltration, prevent mold growth and keep the chimney structure strong. A properly sealed chimney cap will stop further damage and reduce the need for expensive repairs down the track.
Prevent Future Damage with Maintenance
Once your old chimney is restored, you need to maintain it regularly to prevent further damage. Regular chimney inspections by a qualified chimney sweep will pick up small cracks, mortar issues or creosote buildup that could become big problems down the track. Regularly cleaning the flue and chimney repairs to address any wear or damage will extend the life of the former chimney’s structural integrity and keep it safe to use. Sealing small cracks and making sure the chimney cap is in place will stop water and moisture from damaging the structure. A proactive approach to chimney care and regular maintenance will keep your old chimney in great shape for years to come.
