Chimney Repair & Repointing In
Worcester

Weathering is the primary cause of chimney degradation in our region. Frequent cycles of frost and thaw lead to frost heave, where water trapped in the brickwork expands and causes the outer face of bricks to spall or flake away. Over time, the mortar joints between these bricks erode, allowing moisture to penetrate the stack and track down into the chimney breast inside your home. In exposed areas across the Severn and Avon valleys, high wind loads can also loosen chimney pots, damage flaunching, and fatigue lead flashings. Ignoring these early signs of decay often leads to more significant structural damage that can affect the integrity of your entire roofline.

Effective repointing is more than just applying a layer of mortar to the surface. We begin by carefully grinding out the existing, crumbling mortar to a depth of 15-20mm to ensure a solid base for the new application. For heritage buildings and traditional Victorian terraces in Worcester, we select mortar mixes that are compatible with the original masonry, often employing lime-based mortars that allow the brickwork to breathe. This prevents moisture entrapment and ensures the long-term structural health of your stack. Whether working on a simple suburban chimney or a complex shared stack, we focus on matching the colour and finish to maintain the aesthetic character of your property.

The most common leak point on any roof is the junction where the chimney meets the roof tiles. We specialise in replacing failing leadwork with high-quality Code 4 or Code 5 milled lead, installed as soakers and step flashings to create a seamless, watertight seal. If your chimney flaunching—the cement bed holding the pots in place—is cracked, we remove the degraded material and reform the benching with a weather-resistant mix. This directs water away from the stack and prevents it from pooling around the base. Proper lead flashing is essential for ensuring your roof is ready to handle the heavy rainfall that hits the region, effectively protecting your internal timbers from water ingress.

Sometimes a chimney is no longer in use and has become a structural liability rather than a feature. We provide a full service for the safe removal of redundant chimney stacks, carefully dismantling the brickwork down to the roofline. Once the stack is removed, we fill the resulting aperture with sound timbers and install new roofing felt and battens before tiling over the space with reclaimed or matching materials. This eliminates a common source of leaks and maintenance costs, helping to stabilise your roof structure. We always ensure that structural considerations are met and that the resulting roof profile matches the existing tiles or slates perfectly.
