Midhurst's roofing stock is among the most varied in West Sussex — Horsham stone slab on the oldest buildings, clay plain tile on Victorian and Georgian properties, and standard concrete tile on post-war residential. The timber-framed properties around Knockhundred Row and Wool Lane need roofers who understand how building movement affects tile alignment.

In Midhurst, Wealden and Georgian chimney stacks with significant historical variation; Horsham slab surrounds on the oldest properties require specialist handling. Chimney leaks are almost always at the point where the stack meets the tile slope — the flashing — or at the mortar joints in the stack itself. Both are repairable without a full rebuild in most cases.
The most common chimney repair calls in this area: lead flashing replacement or re-dressing, chimney repointing, flaunching renewal (the mortar bed the pot sits in), pot replacement, and stack rebuilds where mortar failure has progressed to the point where the masonry is no longer stable. We assess which category applies at the survey.

📞 01243 278085Yes, lime mortar is mandatory for all work on Midhurst's historic town centre properties and on anything within the conservation area. The timber-framed buildings around Knockhundred Row particularly require it — their constant gentle movement means the flexibility of lime mortar is structurally important, not just a heritage consideration.
"Lead flashing had completely failed on the chimney stack. Properly replaced, not just patched. No more damp on the chimney breast inside."
"Repointing in lime mortar as required. They understood the conservation area requirements without needing to be told twice."
"Flaunching replaced and new pots fitted. Neat job, excellent price. Would recommend to anyone in the area."
Midhurst is inland on the western rother valley, with a more continental climate than the coastal towns — colder winters with more reliable frost, less salt air, but significant damp from the wooded valley setting. For chimney repairs in Midhurst this means Horsham stone slabs appear on some of the oldest properties around the town centre — a roofing material that requires specific handling and sourcing that most standard contractors do not encounter regularly. The market town centre has georgian and victorian commercial and residential property with clay plain tile and welsh slate roofing, while the surrounding streets have 20th-century residential stock. We source horsham stone through specialist reclamation suppliers for the small number of midhurst properties that still have it — getting the material right on these properties is not negotiable.
Chimney repointing in Midhurst typically costs £460–£980. Lead flashing replacement runs £360–£760. Full chimney rebuilds — where the stack is beyond repair — are £3,000–£7,000. We quote after a free survey and scaffold assessment where needed.
The most common causes in Midhurst are failed lead flashing on Georgian properties on Church Hill and Knockhundred Row, open mortar joints on timber-framed properties from building movement, and cracked Horsham slab chimney surrounds on the oldest buildings. We diagnose the exact cause at the survey — the visible symptom (damp patch on breast wall) is usually a different location from the actual defect.

Most chimney problems in Midhurst are repairable — repointing, flashing replacement, pot replacement and flaunching renewal cover the majority of cases. A full rebuild is needed when the stack has structural movement, widespread spalling brick or stone, or where mortar failure has progressed to the point where the masonry is no longer stable. We assess this during the survey.
We would recommend a HETAS-registered sweep and inspection before using the fireplace if the chimney has had water ingress. A leaking chimney stack can cause mortar deterioration inside the flue, and wet or softened refractory material is a potential hazard. Get the chimney repaired and swept before lighting the fire.
Annual inspection is the right interval for most Midhurst properties — ideally in late summer before the heating season starts. Properties in exposed positions, those with lime mortar stacks, and any chimney that has had previous repair work benefit most from consistent annual checking. We include a chimney condition note in our survey reports.
Minor flaunching repairs and pot replacements can sometimes be done from a cherry picker or long ladder on single-storey elements. Full chimney repointing, lead flashing replacement and any structural work on a standard two-storey Midhurst property requires scaffold for safe access and quality of work. Scaffold costs are included in our quotes.
A chimney inspection covers every element that can fail: the flaunching (the mortar bed the pot sits in), the pot condition, the pointing in the main stack body, the lead soakers between each tile course and the stack, the stepped cover flashings on the stack face, the back gutter behind the stack, and the chimney breast internally for evidence of water ingress. In Midhurst, where Rother valley inland properties including Horsham stone stock, the failure patterns we typically find depend on the property age — Victorian and Edwardian chimneys present primarily with lead failure and lime mortar deterioration; post-war properties present with failed sand-cement flaunching and inadequate original flashing specification.
Most chimney problems are repairable without a rebuild. Repointing, lead replacement and flaunching renewal cover the vast majority of cases we survey. A rebuild becomes necessary when the stack has structural movement — visible lean or displacement — when spalling has progressed to the point where individual bricks are structurally compromised, or when mortar failure is so comprehensive that the stack is genuinely unstable. We photograph everything at the survey and give you a clear, evidenced view of which category your chimney falls into. We do not recommend rebuilds when repointing is the appropriate response.
Chimney repointing in Midhurst typically costs £350 to £900 depending on stack height and extent. Lead flashing set replacement runs £350 to £750. Flaunching renewal and pot replacement costs £200 to £500. Full chimney rebuilds — needed where structural movement has occurred — are £2,500 to £6,000 depending on stack size and height. All costs confirmed in a written itemised quote after a free survey.
