Tall multi-flue stacks on Kew’s Victorian and Edwardian homes weather hardest where nobody can see them. FreshDuct repoints, rebuilds crowns, renews lead flashing and relines flues on period stacks, with a drone survey and photographed inspection first.
Damp on a Kew chimney breast? On a multi-flue stack it is often a crown or flashing fault, and we find which before quoting.
The chimneys on Kew’s larger homes are substantial pieces of brickwork, and their height is the problem. Mortar at the top of a tall stack erodes long before the joints at eaves level, the crown that ties several pots together cracks between them, and the lead flashing where the stack passes through a slate roof lifts or splits with age. From the ground all of this is invisible, which is why the first sign is usually a stain on a chimney breast upstairs.
Every Kew repair begins with a drone survey of the stack and a camera inspection of the flues, because a slate roof cannot be walked to have a look. That survey shows whether the water is getting in at the crown, at the flashing or through the joints, and whether the damage is limited to the top courses or has worked down the stack. You get the photos and a firm price for what has actually failed.
The repair itself respects what the house was built with. Joints are repointed in a mortar that suits the original brick, spalled bricks are cut out and replaced with matched ones, crowns are rebuilt to shed water off every pot, and flashing is renewed in lead rather than a modern substitute that sits badly against copper fixings. Where a used flue has cracked, a stainless liner is quoted after the camera has been through it.
Masonry, crown, flashing and flue repairs for tall period stacks on slate roofs, surveyed by drone and quoted firm before any work.
Slate breaks underfoot, and a broken slate beside a chimney is a leak for years. Kew stack repairs are planned from a drone survey and carried out from staging or a platform, so the roof around the chimney is in the same state when we leave as when we arrived.
These roofs were detailed in lead flashing and copper fixings, and a galvanised or aluminium replacement corrodes where it touches them. We renew flashing in the material the roof was built with, dressed into the slate the way the original was.
A multi-flue crown is a wide slab of mortar with pots set through it, and it cracks between the pots as the stack moves. We rebuild it so water sheds away from each pot and clear of the joints below, rather than patching the visible crack.

On a tall Kew chimney the weathering is concentrated at the top, where the wind and rain hit hardest and where the crown, pots and flashing all meet. The lower stack is usually sound, so a repair that stays at the top is the normal outcome.
We show you the drone and camera images with the quote and photograph the finished work from the same angles, so you can compare the two without leaving the ground or going anywhere near the slate.

Rarely. On a tall multi-flue stack the usual cause is a cracked crown or lifted lead flashing at the top, with the lower brickwork still sound. A drone survey and camera inspection show where the water enters, and the repair is normally confined to the top courses.
Yes. Nobody walks the slate. The stack is surveyed by drone first and the work is done from staging or a platform, with flashing renewed in lead so it suits the copper fixings already on the roof. Photos of the finished repair come with the invoice.
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.
