Chimney Repair Services Knutsford
At Roofing Knutsford, we carry out chimney repairs across Knutsford and the surrounding areas, addressing the most common issues affecting both older and newer stacks.
Repointing
The mortar joints in a chimney stack are among the first to show wear. As mortar ages, it becomes porous, cracks and eventually falls away, allowing water to penetrate the brickwork. Repointing involves removing the deteriorated mortar and replacing it with a fresh mix, restoring the weathertight integrity of the stack. It is one of the more straightforward chimney repairs but one of the most important in preventing further damage.
Flashing Repairs
Where a chimney meets the roof slope, lead flashing is used to seal the junction and prevent water from tracking down into the roof structure. This flashing can lift, crack or pull away from the mortar joints over time, particularly after periods of frost or high winds. We repair and replace lead flashing as needed, ensuring the seal between the chimney and the surrounding roof covering is fully restored.
Ridge and Crown Repairs
The top of a chimney stack is usually finished with a mortar weathering, sometimes called a flaunching, which holds the chimney pots in place and directs water away from the top of the brickwork. This can crack and break away with age, leaving pots loose and the top of the stack open to water. We repoint or replace flaunching where required and can reseat or replace chimney pots that have shifted or broken.
Chimney Pot Replacement
Chimney pots can crack or break due to frost damage or impact, and older clay pots on disused chimneys are sometimes removed and replaced with a capping stone or ventilated cap. We can advise on the most suitable option depending on whether the chimney is still in use and fit the replacement accordingly.
Partial and Full Stack Rebuilds
Where deterioration has progressed beyond surface repairs, a section of the stack, or the full stack above roof level, may need to be taken down and rebuilt. This is more involved work but is sometimes the only practical solution where brickwork has become unstable or severely eroded.
