Chimney repair in Caroline Springs means twin-wall flue repair: separated joints, rusted sections, roof penetrations and clearances inside the chase. FreshDuct finds the fault on camera first, then fixes only that.
Stain on a first-floor wall near the chase? That is a flue joint or the roof seal, and a camera tells us which before we quote.
There is no mortar to repoint and no crown to rebuild on a Caroline Springs flue. The system is stainless twin-wall sections locked together, run through a framed chase, past a first floor and out through a tiled or metal roof. What fails is the connections: a joint that was never fully engaged, a section that has rusted where condensate collects, a roof flashing that has perished, or a length sitting too close to the timber framing around it.
Each of those shows up differently in the house. A separated joint leaves a heat mark or a smoky smell on the plasterboard beside the chase. A failed roof seal shows as a damp patch in the ceiling under the penetration. A clearance problem shows as scorched framing that only a camera inside the chase will find. So every repair begins with the camera and photos, not a quote.
Once the cause is on camera we quote the fix that matches it: re-engaging or replacing joints, swapping a corroded section, resealing or replacing the roof penetration, or correcting a clearance with the right shield. Where the appliance is a gas fireplace, we camera and photograph the flue so the fault is documented, and the repair goes through the licensed gas specialists we arrange.
Twin-wall flue, joint, roof penetration and clearance repairs on Caroline Springs estate homes, quoted firm after a photographed camera inspection.
The concealed run through the first floor carries most of the joints, and a joint that has crept apart cannot be seen from the room. We camera every connection in the chase and re-engage or replace the ones that have moved.
The flashing where a twin-wall flue leaves a Caroline Springs roof perishes long before the steel does. A cracked seal lets water track down the outer casing into the ceiling, and replacing it is a small job when caught early.
A flue boxed into a framed chase has to keep its distance from the studs and noggins around it. We check the clearances on camera and correct any that were built too tight, before they become a scorch mark.
Real photos from Melbourne jobs — not stock, not staged.




A two-storey twin-wall flue is a series of sections, and most faults are in one of them. The camera inspection shows which joint, which section or which seal has let go, so the quote covers that part rather than a full replacement.
You get the inspection photos with the quote and photos of the repair with the invoice, so a problem hidden inside a chase is something you can actually see before and after.

Usually heat from a joint that has separated inside the chase, sometimes a leak from the roof penetration above. We camera the concealed run to find which, photograph it and quote the specific repair before touching anything.
It can be repaired in sections. Twin-wall systems are modular, so a rusted length, a loose joint or a perished roof seal is replaced on its own. Full replacement is only quoted where the camera shows the system as a whole has failed.
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.
