A chimney takes more weather than almost anything else on a house: rain, frost, wind-driven damp and flue heat all working on the same stack of brick or stone. In Bristol's older terraces and Victorian villas, that usually shows up as crumbling mortar joints, a cracked crown, slipped flashing where the stack meets the roof, or a leaning stack that's pulled away from the ridge line. Chimney masonry covers the repair side of all this: repointing, rebuilding courses above the roofline, replacing a cracked crown or chimney pot, fitting new lead flashing, and installing a cowl or capping to keep water and birds out of an unused flue.
When you're choosing a contractor for this work, a few things matter more than a low quote. Ask whether they'll actually get up on the roof to inspect the stack close up, rather than quoting from ground level with binoculars. Ask what mortar mix they use: lime mortar is usually the right call on older solid-wall Bristol properties, while cement-based mixes can trap moisture and cause more cracking over time. Check they carry height-work insurance and will scaffold or use proper roof ladders rather than a single extension ladder for anything beyond minor repointing. And get clarity on whether the price includes making good the roof covering around the stack, since a chimney repair that leaves a leaky flashing detail hasn't actually fixed the problem.
