This is the starting point for any Bradley Stoke chimney survey — establishing which of three distinct situations you're dealing with, because each requires a completely different approach.
Type 1 — No Chimney
The majority of Bradley Stoke's housing stock, particularly the terrace and smaller semi-detached properties across the development, was built without any chimney structure. These properties have gas central heating with balanced flues discharging through external wall vents. There is no stack, no pot, and no chimney maintenance requirement whatsoever. If you have this type of property and you're concerned about a roofing problem near where a chimney would have been, the issue is likely ridge mortar, dry verge, or flashing at the roof slope junction — none of which are chimney repairs.
Type 2 — Decorative Stack with Gas Fire Insert
Some of Bradley Stoke's larger semis and detached properties — particularly executive homes from the 1990s phases — were built with a decorative chimney stack containing a stainless steel flue liner serving a gas fire or gas log effect insert in the living room. These stacks look like traditional chimneys but function differently. The mortar and flaunching maintenance is similar to a conventional stack. The flue is a stainless steel liner rather than open brickwork — and when the gas appliance is serviced or replaced, the liner condition becomes a servicing question as well as a roofing one.
Type 3 — Fully Decorative Stack
The most surprising chimney situation across Bradley Stoke — decorative chimney stacks that were added to properties purely for aesthetic purposes, with no flue of any kind. These stacks project above the roofline, have chimney pots, and look from the street exactly like functional chimneys. Inside, the stack is solid block or filled. There is no flue. When the mortar, flaunching, or lead flashing on one of these stacks fails, it causes exactly the same damp problems — water ingress through the stack, damp on the internal wall near the stack base — as a functional chimney failure. The repair approach is identical to a conventional stack repair.
We identify which type applies to your Bradley Stoke property during the drone survey. The repair scope, mortar specification, and flue considerations are all determined by which category the stack falls into.
Chimney and Ridge Junction Survey
A combined assessment of the chimney stack condition and the ridge mortar condition in the surrounding area — the only way to correctly diagnose a chimney area leak on a Bradley Stoke new build property. Drone survey plus written report standard on every BS32 chimney enquiry.
Decorative Stack Maintenance — Mortar and Flaunching
Repointing and flaunching replacement on Bradley Stoke's decorative chimney stacks in the correct mortar specification for the harder modern brick used in 1980s to 2000s construction. Not lime mortar — the soft brick specification required on Victorian properties doesn't apply here.
Lead Flashing Repair and Replacement
Code 4 step flashings and Code 5 cover flashings at chimney stack junctions, correctly dressed and wedged into the mortar joint. On Bradley Stoke's decorative stacks where the original flashing was developer-installed, the specification is frequently minimum grade — thin lead, inadequately dressed, and now lifting after 30 to 40 years of thermal cycling.
Gas Flue Liner Assessment Referral
Where a Bradley Stoke property has a Type 2 stack with a gas fire insert, any concern about the flue liner condition — as opposed to the external stack — is referred to a Gas Safe registered engineer who can assess the liner internally. We handle the external stack and flashing repair; the internal flue liner assessment is a gas safety matter outside roofing scope.
Ridge Mortar Repair and Dry Ridge Upgrade
Where ridge mortar failure near the chimney stack is the actual source of the leak, we re-bed and repoint affected ridge tiles or — on properties where the full ridge is deteriorating — upgrade to a dry ridge system. Dry ridge is mechanically fixed without mortar and carries a 20+ year guarantee — eliminating the mortar maintenance cycle on a Bradley Stoke new build that will likely outlast the original tile.
Decorative Chimney Stack Removal
Where a purely decorative stack is causing maintenance cost and the homeowner would prefer to remove it, we take the stack down below the roofline, close the roof in matching concrete interlocking tile, and make good the ridge at the junction point. Significantly reduces long-term maintenance on properties with no functional use for the stack.

My Bradley Stoke property has a chimney but I don't think it has a real fire — what type is it?
Check whether there's a fireplace opening in the living room and whether it has a gas fire or log-effect insert. If yes, it's a Type 2 stack with a gas flue liner. If the fireplace opening is blocked with a decorative board or there is no opening at all, it's a purely decorative Type 3 stack. If there's no chimney visible externally, your property has no chimney structure and any roof junction leak near a gas flue vent is a different repair category entirely.
I have damp near the chimney area on the ceiling — is it the chimney or the ridge?
Both are possible and both need to be assessed together. Failed ridge mortar near the chimney junction is the most commonly misdiagnosed source of ceiling damp in this area of a Bradley Stoke property. Our combined chimney and ridge survey establishes which one — or which combination — is the actual cause before we recommend any repair.
My decorative chimney stack has never been used — does it still need maintenance?
Yes. Decorative stacks are still exposed to weather and still deteriorate through mortar joint failure and flaunching cracking. The maintenance requirement is identical to a functional stack. The only difference is that there's no flue liner or gas appliance to consider.
Can you remove the decorative chimney stack completely?
Yes. Where the stack is purely decorative and the homeowner would prefer to remove the maintenance requirement, we take it down below the roofline and reinstate the roof covering in matching tile. It's a straightforward job on a concrete interlocking tile roof.

Yes. Call 0117 370 9986 for same-day response across BS32.
