Hills Roofing Ltd provides specialist chimney repairs in Surrey for homeowners across the whole county. Based in Croydon CR0 on the Surrey border, we carry out chimney repointing, lead flashing repair and replacement, flaunching work, pot replacement, and partial stack rebuilds on properties from Sutton and Cheam through to Epsom, Banstead, Guildford, and beyond. Connor Hill personally surveys every chimney and oversees all repair work, with no subcontractors and no work carried out by a crew you haven't met.
Surrey's large stock of Victorian and Edwardian housing means there are thousands of original brick chimney stacks across the county, many of which have received little or no attention in decades. Chimney deterioration is gradual and easy to miss from ground level, but the consequences of leaving it unaddressed, particularly failed pointing or lifted flashing, include progressive water ingress that damages roof timbers, internal walls, and ceilings.
The most frequent chimney defects we diagnose and repair on Surrey properties include:
Many of these defects are only visible on close inspection from the roof, which is why a proper survey, rather than a ground-level assessment, is essential before recommending any repair programme.
Chimney repointing is among the most common jobs we carry out across Surrey. On Victorian and Edwardian stacks, the majority of Surrey's chimney stock, we use a lime-based mortar mix appropriate to the age and construction of the brickwork. Cement-heavy mixes on older brickwork trap moisture inside the brick and accelerate spalling; using the correct softer mix allows the stack to breathe and moves moisture to the mortar joint where it can evaporate safely. This is a technical distinction that matters; we won't repoint an old stack with modern OPC cement to save time.
Lead flashing is the weathertight seal between the chimney and the roof slope. It consists of several components: step flashings up the sides of the stack, a back gutter flashing behind it, and soakers beneath each course of slates or tiles. When any of these components lift, crack, or lose their lead wedges, water tracks down the roof structure into the ceiling below. Hills Roofing Ltd repairs and replaces chimney flashing across Surrey using high quality lead as appropriate, correctly dressed, wedged, and pointed into the mortar joints.
Flaunching, the sloped mortar bed at the top of the stack, supports and seals the chimney pots. Where flaunching has cracked and lifted, pots become unstable and the top of the stack is exposed to water. We cut back deteriorated flaunching, lay a new mortar bed, and re-seat existing pots or supply and fit replacements. Where chimney pots are no longer needed, such as a sealed-off fireplace, we can fit a suitable weathering cap over the flue opening.
Where a stack has deteriorated to the point where repair is no longer cost-effective, with severe spalling throughout, structural bulging, or significant settlement, a partial or full stack rebuild is the correct approach. We dismantle from the point of failure, source matching brickwork where possible, and rebuild with new flaunching, pots, and lead flashing. All stack rebuild work is carried out from scaffold and comes with a written workmanship guarantee.

Chimney repointing in Surrey typically costs between £300 and £700, depending on the height and size of the stack and the extent of mortar failure. Taller stacks or those requiring scaffold will be at the higher end. Hills Roofing Ltd provides free chimney surveys and written fixed-price quotes across Surrey. Contact us for an accurate figure for your property.
From ground level, visible signs include crumbling or missing mortar joints between bricks, white salt staining (efflorescence) on the external face of the stack, and internal damp patches on the chimney breast. If your chimney pot appears tilted, that usually indicates flaunching failure. A proper assessment requires inspection from roof level; Hills Roofing Ltd will survey the chimney safely and advise on what's needed.

Lead flashing is always the correct long-term solution for chimney weathering. Mortar-based chimney repair products and roofing sealants applied as a quick fix will typically fail within a few years, as they cannot accommodate the thermal movement that causes the original mortar to crack in the first place. Hills Roofing Ltd uses lead flashing to the correct code specification for all chimney weathering work.
For very minor chimney pot or flaunching repairs on low-pitched or accessible roofs, it may be possible to work from a roof ladder. However, most chimney repointing, flashing replacement, and stack rebuilds require scaffold for safe working at height, and we will not undertake work unsafely to avoid that cost. Scaffolding is included in the overall quote and is arranged by Hills Roofing Ltd as part of the job.
