Chimney repair specialists covering Bradford-on-Avon and the BA15 area. Lime mortar repointing, lead flashing, pot replacement, stack rebuilding for conservation area and period properties. Free quotes.
Chimney trouble shows as damp on the breast inside, crumbling mortar, or a leak where the stack meets the roof. On Bath's soft stone stacks, eroded lime pointing and failed lead are the usual causes.
Damp staining on the chimney breast inside the house
Crumbling or missing mortar in the stack
A leak in the ceiling near the chimney
Loose or leaning pots
Vegetation growing from the stonework
When it is not the answer: If only the flaunching or a length of flashing has failed, you don't need a full rebuild — a targeted lime repair is far cheaper and keeps the original stack. Read the full guide.

Chimney Repairs Bradford-on-Avon
Bradford-on-Avon's chimney repair market is almost entirely period property work. The town centre and historic residential streets have dense concentrations of 17th to 19th-century stone properties, all with chimneys built from Corsham Down limestone or local rubble stone, and all requiring lime mortar for any repair work. Using cement mortar on these properties causes irreversible damage to the soft stone through thermal movement and frost action.
Lime Mortar Chimney Repointing in Bradford-on-Avon
We use NHL 2 or NHL 3.5 lime mortars on all Bradford-on-Avon stone chimneys, matched to the original pointing profile. For listed buildings, we document mortar mixes and sources for the property's conservation file. Lead flashing on Bradford-on-Avon's stone chimneys is stepped flashing and back gutter detailing — the most common repair type on period properties in BA15, and one that requires careful lead dressing to the Code of Practice standard.

The process
How a Bradford On Avon Chimney Repairs Job Runs
1. Four-face survey
We inspect every face of the stack — the weather-facing sides erode faster than the one you see — and photograph the faults.
2. Written quote
We quote the repointing, flashing, flaunching or rebuild needed, using lime mortar for Bath's soft stone, at a fixed price.
3. Scheduling & access
We book the work and arrange the tower or scaffold access a stack needs for safe standing time.
4. The work
We rake out failed mortar, repoint in matched NHL lime, renew lead flashing and flaunching, and re-bed pots as needed.
5. Cleanup & sign-off
We clear debris, leave the stack weathertight, and hand over your guarantee.

Access
Getting Safely onto Bradford On Avon Roofs
Chimney work almost always needs a tower or scaffold for safe standing time at the ridge — itemised in your quote, never a hidden extra. Scaffold is specified for: nearly all stack work — safe access to the ridge is essential and always specified - always itemised in your written quote, never a hidden extra, and we arrange it.
Bradford-on-Avon's steep weavers' terraces and stone cottages climbing the hillside make access and scaffold footing a real consideration. Pavement scaffold and skip permits go through Wiltshire Council; allow a few working days on streets like Silver Street, Market Street, Newtown, Middle Rank where space is tight.

Chimney workmanship is guaranteed for 10 years, extending to rebuilds and full repointing; because we use correct NHL lime, the work lasts rather than damaging the stone as cement does.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
What It Is Like While We Work
Stack work means access equipment up for a few days and some mess at the base — we sheet and protect below, and clear everything on completion. You do not need to stay home for external work - we just need power and access agreed in advance.
Lime pointing waits for frost-free weather to cure; we won't point a stack into a cold snap and risk the mortar failing. The Avon valley here traps humidity and the tightly-packed stone terraces see accelerated moss on shaded slopes.

Pricing and Process
What to Expect from Chimney Repairs
How We Price Chimney Work
Chimney repair pricing is driven by three variables: height (which determines scaffold or access equipment cost), extent of mortar failure (how many courses need repointing), and lead specification (whether step flashings, back gutters, or saddles need replacement alongside the masonry work). We always inspect the full chimney — all four faces, not just the accessible street-facing side — before providing a quote. Work found on the less visible faces is included in the original quote, not added as a surprise on completion.
Mortar Matching on Period Properties
One of the most visible quality differentials between chimney repointing contractors is mortar colour matching. Lime mortar comes in a range from near-white to warm buff depending on the aggregate used, and Bath stone properties in particular show mismatched pointing very clearly. We carry iron oxide pigments and a range of aggregates to match the existing mortar colour as closely as possible. For listed buildings where the planning authority may inspect the completed work, we prepare a sample panel for approval before committing to the full stack.
After the Repoint — What to Check
A correctly completed chimney repoint should show no mortar smearing on the face of the brickwork or stonework, clean raked joints at a consistent depth, and a struck profile that matches the original. Flashings at the base should be dressed tight to the masonry with no visible gaps. Flaunching around pots should be smooth with no cracking. If you notice any of these issues after a repointing job, call the contractor back before the mortar has fully cured — remedial work on fresh lime mortar is straightforward; remedial work on hardened mortar requires breaking out and starting again.
