Doncaster East chimneys take the weather on their ridgeline streets, whether they are 1970s brick stacks with tired crowns or steel flues whose roof collar has perished. FreshDuct repairs crowns, mortar, flashing and flue collars, and relines brick flues, after a photographed inspection.
Water tracking down a Doncaster East flue after rain? On a steel flue that is usually the roof collar, and it is a small fix.
The repairs a Doncaster East chimney needs depend on which decade built it. The 1970s and 80s brick stacks have a crown that cracks with age, mortar that has weathered on the face the wind hits, and flashing that has lifted at the roof line. The newer homes have no masonry at all; their steel flues pass through the roof in a flashing collar, and it is that collar, not the flue, that perishes and lets water in.
The ridgeline setting makes both worse. Wind-driven rain finds the hairline in a crown and the split in a collar that gentle rain never would, so a Doncaster East home on a rise can have a leak its neighbour lower down the street does not. Our inspection photographs the crown, the mortar on the exposed face, each flashing edge or the collar, and the flue itself, and the quote covers only what has failed.
On the brick stacks we rebuild crowns with a fall and a drip edge, repoint the weathered face, replace any spalled bricks and reseal or replace the flashing. On steel flues we replace the collar and re-seal it to the roof. Where a wood heater has been inserted into an old brick fireplace and the original flue is now too big or cracked for it, a stainless liner sized to the heater is quoted after the camera has confirmed it.
Crown, mortar, flashing and collar repairs for Doncaster East brick stacks and steel flues, plus stainless relining, quoted firm after we have photographed the fault.
The crown on a 1980s Doncaster East stack is the flat top that takes every drop of rain, and once it cracks the water goes into the brickwork below. We rebuild it with a fall so it sheds water away from the flue.
On a newer Doncaster East build, the rubber or metal collar where the steel flue meets the roof is the part that fails, splitting in the sun and wind. We replace it and seal it to the roof rather than patching it with silicone.
Some 70s and 80s Doncaster East fireplaces now hold an inserted wood heater venting into the original oversized brick flue. That draws poorly and lays down creosote, and a stainless liner sized to the heater is the proper repair.

A leaking brick stack and a leaking steel flue in Doncaster East look the same from the lounge, a stain on the ceiling near the fireplace, but the fix is a crown or flashing job on one and a collar on the other. We find out which before quoting.
The photos from the inspection come with the quote, the photos of the repair come with the invoice, and if the stack turns out to be sound we say so rather than invent a job.

Almost always it is the collar where the flue passes through the roof, not the flue itself. Sun and ridgeline wind split it over the years. We inspect and photograph it from the roof, replace the collar and seal it, and check the flue is sound while we are there.
That is the windward face. On a ridgeline street one side of the stack takes the driven rain and weathers years ahead of the sheltered side. We repoint the weathered face, check the crown above it, which is usually cracked too, and photograph both.
White staining, crumbling mortar, loose or missing bricks, rust marks on the roof, water in the firebox after rain, or smoke seeping into rooms are the usual signs. A photographed inspection tells you what is cosmetic and what is not.
Yes — stainless steel liners for cracked or unlined flues on open fireplaces and wood heaters, quoted firm after a camera inspection. Gas flue work goes through the licensed gas specialists we arrange.
Often, with roof access and harness work. Taller or unstable stacks need scaffold, and we tell you before quoting rather than after.
