- Chimney brick repair: it’s usually either the brick itself that’s falling apart or spalling, or the mortar that binds the brick together that chips or flakes off. Depending on the extent of the damage (remember, some may appear like fine or superficial cracks, but actually run deeper), the repair may range from a simple replacement of the spalled brick with a similar-coloured brick, to grinding out the defective mortar joint and carefully reapplying new mortar, to a complete chimney replacement to below the flash point if there is extensive damage.
- Tuckpointing: if it’s the mortar joint that needs some TLC, after grinding out the defective mortar, new mortar is reapplied, and we often use a special technique called tuckpointing to apply a durable and long-lasting mortar that consists of different shades to create a fine joint illusion, creating a beautiful depth that will enhance your property.
- Chimney crown replacement: the cap does exactly what it looks like it would do - create a barrier to prevent debris, twigs, leaves and water from entering the chimney. A cracked chimney crown risks failing to do its job.
- Fixing the chimney flue: this is the inner lining of the chimney, and can be subjected to heat and stress which can cause the material to crack. This is usually detected on the annual chimney inspection, and must be fixed in a timely manner to prevent heat and smoke from entering in areas of the home that would cause a fire risk.
How can you tell you need a repair?
Some tell-tale signs include:
- Visual inspection of the brick and mortar: can you see broken bricks or deficient mortar from where you are? If it’s already obvious from where you’re standing below, the damage is likely more extensive the closer you get to it.
- White/gray salt stains: this is called efflorescence and a small amount on brick, stone or concrete can be common, but excessive amounts indicate the presence of too much water which can be detrimental to the masonry unit.
- Fallen tiles and water pooling in the fireplace: this is a clear indicator that a chimney inspection and repair are needed.
