Methods for chimney stack repairs
Repointing and brick repairs
Eroded joints are raked out and repointed in a mortar suited to the brick, often a lime-based mix on older stacks. Spalled or cracked bricks are cut out and replaced with matched reclaimed or new bricks. On many stacks this, with new flaunching, is all that is needed.
Best for: Upright stacks with weathered joints and some damaged bricks
Partial or full rebuild
Where the lean is pronounced or the brickwork is badly decayed, the stack is taken down to sound masonry, often to roof level, and rebuilt plumb with new flashings and flaunching. Original bricks are cleaned and reused where possible to keep the appearance.
Best for: Badly leaning or decayed stacks
From first photo to finished repair
Check what is below
We ask whether any chimney breasts have been removed, and check the loft and rooms below for cracking. If a breast has gone without proper support, we recommend an independent chartered structural engineer before any stack work.
Repair, restrain or rebuild
The agreed work is carried out: repointing, new flaunching and pots, restraint, or taking the stack down and rebuilding it. Lead flashings where the stack meets the roof are checked and renewed if needed.
Weatherproof and clear
Caps or cowls are fitted where agreed, the roof around the stack is checked for slipped tiles, and debris is cleared from gutters. You receive photos of the finished stack taken from the scaffold, since it is hard to see from the ground.
Rules for chimney stack repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Frequently asked questions
What is the price of chimney stack repairs in Sunderland?
Guide prices for chimney stack repairs in Sunderland start from about £460 per stack, including VAT, on North East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out chimney stack repairs in Sunderland?
We do. Sunderland and the surrounding area are covered, including nearby Seaham and Washington. A free initial assessment from your photos is the first step.
Does the ground around Sunderland cause cracking?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay. Only an investigation can say why a particular building has moved.
Is a leaning chimney dangerous?
A leaning chimney can become dangerous, because stacks are heavy and stand high above the roof. A slight, long-standing lean may be stable for now, but a lean that is worsening, or loose bricks and pots, should be looked at quickly. Keep people away from below if anything looks loose.
Can a leaning stack be straightened?
Not by pushing it back, because the brickwork would crack. A slight lean on a sound stack can be restrained so it moves no further. A pronounced lean is fixed by taking the stack down to sound masonry and rebuilding it plumb.
