Chimney Repair Services
Brickwork and Masonry Repair:
-
Cracks and Deterioration: Chimney bricks and mortar can crack and deteriorate, leading to potential structural issues. Repairing these cracks is vital to maintaining the chimney's stability.
-
Repointing: This involves renewing the external part of mortar joints, ensuring the bricks are held securely together and preventing water ingress.
Chimney Relining:
• Liner Replacement: The chimney liner protects the chimney walls from heat and corrosion. Over time, liners can crack or corrode and need replacement to ensure safe operation.
• Types of Liners: Liners can be made from materials such as clay, metal, or cast-in-place. Each type has its benefits and is chosen based on the specific requirements of the chimney.
Crown Repair:
• Crown Cracks: The chimney crown, located at the top of the chimney, can develop cracks that allow water to seep in. Repairing these cracks prevents water damage to the chimney and the interior of the house.
• Sealant Application: Applying a waterproof sealant to the crown can prevent further cracking and extend the life of the chimney.
Flue Repair:
• Blockages and Obstructions: Debris and creosote can build up inside the flue, causing blockages. Clearing these obstructions is crucial to ensure proper ventilation and prevent fire hazards.
• Flue Replacement: If the flue is extensively damaged, replacement may be necessary to ensure the chimney functions correctly and safely.
Types of Chimney Flashing
Step Flashing:
• Installed in a series of steps alongside the roof slope, step flashing directs water away from the chimney and roof intersection.
• Each piece overlaps the shingle below, providing a continuous water barrier.
Counter Flashing:
• Counter flashing is embedded in the chimney mortar and overlaps the step flashing. This additional layer further protects against water ingress.
• It can be constructed from durable materials such as lead, which offers a long-lasting solution.
Apron Flashing:
• Located at the base of the chimney, apron flashing extends down the roof to direct water away from the chimney base.
• It works in conjunction with step and counter flashing to provide comprehensive protection.
Signs to look out for
Identifying the signs that your chimney needs repair or flashing services is key in preventing further damage and ensuring your home remains safe for the occupants. A damaged chimney can cause carbon monoxide poisoning so keep these signs in mind and if in doubt, get in touch.
Visible Cracks and Damage
• Cracked Bricks and Mortar: Visible cracks in the chimney bricks and mortar joints can indicate structural weaknesses that need immediate attention.
• Damaged Crown: Cracks or deterioration in the chimney crown can lead to water infiltration, necessitating repair.
Water Leaks
• Water Stains on Walls and Ceilings: Discolouration or water stains inside your home, near the chimney, indicate water leaks that could stem from damaged flashing or chimney masonry.
• Mould and Mildew: The presence of mould or mildew around the chimney area is a sign of excessive moisture, often due to flashing issues.
Smoke Backdrafts and Poor Ventilation
• Smoke in Living Areas: If smoke is not venting properly and is backing up into the living space, it could indicate a blockage or damage in the flue.
• Odour: A strong, unpleasant smell emanating from the fireplace when not in use may signal creosote build-up or chimney damage.
Efflorescence
• White Staining on Bricks: The appearance of white, powdery stains on the exterior of the chimney indicates efflorescence, a sign that water is moving through the masonry and leaving salt deposits behind.
