Chimney Stack Repairs in Marlow

Over time, the mortar joints between your chimney bricks can begin to crack and erode. This is often caused by a combination of harsh Thames Valley weather, including heavy rain and wind, alongside the natural freeze-thaw cycle which expands existing gaps in the masonry. Furthermore, the acidic nature of flue gases can accelerate the breakdown of internal and external mortar. We address these issues through precise chimney repointing, using high-grade mortar mixes that match the aesthetics and requirements of your specific property type. We also assess the chimney flaunching, the sloped cement finish at the top of the stack that seals the flue, to prevent moisture from seeping directly into the brickwork.
