Expert Chimney Repair Services

Your chimney sits at the highest point of your property, taking the full force of wind, rain, frost and sun year-round. This constant exposure means chimneys deteriorate faster than almost any other part of your roof.

From crumbling mortar and cracked flaunching to lifted lead flashing and failing brickwork, we diagnose problems accurately and fix them properly. Every job starts with a thorough inspection so you know exactly what needs doing, with no pressure.

Chimney rebuild by Vanguard Roofing

Chimney Repair Services

Every chimney is different. We carry out the full range of chimney work, tailored to the age, construction and condition of your stack.

Chimney Repointing

Failed mortar joints raked out and replaced with correctly matched mortar. We use lime mortar on period and listed properties to prevent damage. A properly executed repoint lasts 20-30 years.

Flaunching Repairs

Cracked or failed flaunching removed and re-formed with durable mortar to shed rainwater and hold pots securely. Includes inspecting and re-bedding chimney pots into the new flaunching.

Lead Flashing

Re-dressing, resealing or full replacement of chimney lead flashing where it has lifted or pulled away. Step, soaker and apron flashing fitted using code 4 or code 5 lead to BS standards.

Pots, Cowls & Guards

Replacement chimney pots matched to your property style. Rain caps, cowls and bird guards fitted to protect flues from water, debris and nesting.

Rebuilds & Structural

Partial or full chimney rebuilds using matching brick and bond patterns. New flaunching, pots and lead flashing included as standard.

Removal & Capping

Unused chimneys removed to roof level and capped with ventilation. Eliminates ongoing maintenance while keeping the roof weathertight.

Heritage & Listed Buildings

Period properties need specialist care. We use traditional lime mortars, source reclaimed materials and work within listed building regulations to preserve your property's character.

Signs Your Chimney Needs Repairing

Catching problems early saves money. Look for these warning signs:

From Outside

  • Cracked or crumbling mortar joints
  • Visible cracks in the flaunching
  • Leaning or tilting chimney stack
  • Spalling or flaking brickwork
  • Lifted or displaced lead flashing
  • Loose or missing chimney pots

From Inside

  • Damp patches on the chimney breast
  • Peeling wallpaper or bubbling paint
  • Musty or damp smell near chimney
  • White salt deposits (efflorescence)
  • Water dripping into the fireplace

Small repointing or flaunching repairs done promptly can prevent far more expensive rebuilds later. Get a free inspection if you have noticed any of these signs.

Chimney Repair FAQs

Yes, absolutely. Even if you no longer use your fireplace, the chimney stack is still exposed to the weather and will continue to deteriorate. Failed mortar, cracked flaunching and damaged flashing can all allow water into the roof structure and your home, causing damp, staining and potentially serious structural damage. Regular maintenance or, if appropriate, removing the stack and capping the flue are both sensible options for unused chimneys.

The cost of chimney repairs varies significantly depending on the type and extent of the work needed. Simple repointing or flaunching repairs are relatively affordable, while a full chimney rebuild will be a larger investment. Scaffolding requirements also affect the price. The best way to get an accurate figure is to arrange a free inspection, which we provide with no obligation across Hampshire, Wiltshire and Berkshire. Call 0118 408 0811 for a free quote.

In most cases, yes. Chimney stacks are at the highest point of your property and safe access is essential for both the quality of the work and the safety of our team. For some minor repairs on lower roofs, we may be able to use ladders, but scaffolding is usually the safest and most practical option. We arrange all scaffolding as part of the job and include it in our quote, so there are no hidden costs.

Most chimney repointing, flaunching and lead flashing repairs can be completed within one to two days once scaffolding is in place. Partial rebuilds typically take two to three days, while a full chimney rebuild may take three to five days depending on the size and complexity. We will always give you a clear timeline before work starts so you know what to expect.

Damp on the chimney breast is most commonly caused by water getting in through the chimney stack, but it is not always the case. Failed lead flashing, cracked flaunching, damaged mortar joints and even condensation within a disused flue can all cause internal damp. Occasionally, the cause may be elsewhere in the roof. We will carry out a thorough inspection to identify the exact source of the problem before recommending any work, so you only pay for what is actually needed.

Not particularly. Most chimney repairs are carried out from the outside, so there is minimal disruption inside your home. Scaffolding will need to be erected, which may temporarily restrict access to part of your garden, but the work itself is generally confined to the roof and chimney. We keep our work areas clean and tidy, and we always let you know what to expect before we start.
