Arundel's flint chimneys need contractors who specify lime mortar correctly, understand conservation area requirements, and know how to access steeply sloping hillside sites. We've been carrying out chimney work across Arundel for years.
Arundel's chimney repair work requires a level of material knowledge and planning sensitivity that goes beyond standard domestic roofing. The town's distinctive housing stock — Georgian and Victorian properties clustered below the castle, flint-built cottages on steep lanes, chalk-block and brick farmhouses on the surrounding plain — covers almost every historic masonry type found in West Sussex, and each requires a different approach to mortar specification and material matching.
The River Arun valley location adds a climatic dimension. Properties on the lower slopes below the castle sit in a persistent moisture zone from river valley humidity, and this accelerates mortar deterioration and lead oxidation at rates noticeably higher than elevated neighbouring properties. Chimneys on north-facing and river-facing stacks in Arundel are among the most frequently repaired in our whole coverage area.

Why Arundel Specifically
Arundel sits in the arun valley beneath the chalk downland, where cold air pools overnight and frost cycling is more severe than on the surrounding coastal plain. For chimney repairs in Arundel this means lead flashing failure on north-facing slopes is accelerated by the valley frost patterns, and the flint construction requires specialist pointing knowledge that most standard contractors do not have. The flint-built properties around the castle and the victorian terraces descending to the riverside have construction that demands lime mortar and matched reclaimed materials. We carry reclaimed clay plain tiles and mix lime mortar on site for arundel jobs — the castle town's heritage character means shortcuts on materials are immediately visible.
Lime Mortar: Non-Negotiable in Arundel
Every chimney repair we carry out on Arundel's flint and brick period properties uses lime mortar. The local building tradition — flint panels with brick quoins and lime pointing — requires a mortar that is softer than the masonry, breathable, and flexible enough to accommodate the movement of a structure that may be 200 years old. Portland cement in an Arundel period chimney causes spalling of the flint faces and brick arises within 10 to 15 years. We mix to the correct NHL specification on site.

How to Tell You Need Chimney Repairs
Chimney problems in Chichester — damp on the breast, staining, loose pots — almost always trace to failed flashing, cracked flaunching or open pointing letting water into the stack.
Damp or staining on the chimney breast inside
Loose or leaning chimney pots
Crumbling mortar visible in the stack joints
White staining (efflorescence) on the brickwork
A leak that appears near the chimney after rain
When it is not the answer: If the underlying covering is sound and the problem is localised, a targeted repair is the honest answer rather than a larger job. Read the full guide.

Access
Access, Scaffolding & Permits in Arundel
Access is by tower, ladder or scaffold depending on the job and the property; scaffold is always itemised in the written quote. Scaffold is specified for: any job needing safe standing time at height - always itemised in your written quote, never a hidden extra, and we arrange it.
Arundel's steep historic High Street and dense listed stock mean challenging access and strict conservation control on any visible work. Pavement scaffold and skip permits go through Arun District Council; allow a few working days on streets like High Street, Maltravers Street, Tarrant Street where space is tight.

Disruption, Mess & Weather
We keep disruption to a minimum, protect the area below the work, and clear everything before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Most work runs year-round; temporary weatherproofing goes on the same day if rain interrupts. Arundel's Arun-valley setting brings river humidity and sheltered but damp conditions.
FAQ
Frequently Asked Questions
Chimney repointing in Arundel costs £200–£600 depending on stack size and whether lime or specialist mortar is required. Lead flashing strip and re-dress: £350–£800. Chimney pot replacement: £150–£400 per pot. Free quotes on all chimney work.
Lime mortar — always. Portland cement is harder than flint and the surrounding mortar joints, and causes spalling over time. All our Arundel chimney repointing uses appropriately specified lime mortar mixes. We can advise on the correct strength and composition for your specific stack.
Like-for-like repairs using correct materials (lime mortar, matching flint, appropriate brick) generally do not need consent. If you are changing the chimney configuration, removing or adding pots, or raising/lowering the stack height, conservation area consent may be needed. We advise during the survey.
Yes. We're experienced with scaffold and access tower work on Arundel's steeply sloping sites and the narrow access lanes typical of the town. We assess access requirements during our initial visit and include all scaffold costs in our quotes.
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 Arundel 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 Arundel property requires scaffold for safe access and quality of work. Scaffold costs are included in our quotes.
Chimney Inspection Process in Arundel
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 Arundel, where flint-built period properties and chalk downland frost exposure, 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.
Repair vs Rebuild: How We Assess
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 Repair Costs in Arundel
Chimney repointing in Arundel 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.
