If you're trying to work out what a chimney take-down is likely to cost at your Mildenhall property, this page sets out the typical price range and explains the factors that push costs up or bring them down.
A standard chimney take-down on a two-storey house - including removal of the stack to below roof level, fitting a lead slate, re-tiling, and clearing all waste - typically costs in the region of £800 to £1,500. Most straightforward jobs on a standard semi-detached or detached house fall within that range.
Larger stacks, more complex roof types, difficult access, or the need for reclaimed tiles will push costs towards the top of that range or beyond it. Smaller, simpler stacks on single-storey outbuildings or rear extensions are often cheaper. These figures are for the roofing work only and do not include any internal work such as sealing the fireplace opening or making good the chimney breast inside.
Scaffolding is one of the biggest variables in chimney take-down pricing. For a chimney on a two-storey house, a section of independent scaffold or a chimney scaffold is almost always needed to carry out the work safely and to a proper standard.
Scaffold hire typically adds £300 to £600 to the overall cost, depending on the size of the structure needed and how long it's in position. Some jobs can be done from a ladder with a proper standoff bracket, but this is only appropriate for lower chimneys or single-storey work. If a quote you receive is notably cheaper than others, check whether scaffolding is included or has been omitted to reduce the headline price.
A chimney stack that serves two or three flues is physically larger than one serving a single flue. A bigger stack means more brickwork to remove, more waste to dispose of, and a larger area of roof to re-tile once it's gone. The lead slate fitted over a twin-flue stack also covers a larger area and uses more lead.
The height of the stack above the roof line also affects the price. A tall stack - one that projects a metre or more above the ridge - involves considerably more brickwork than a short one sitting just above the tile level. If the stack is tall and in poor condition, extra care is needed during demolition to avoid sending material down the roof.
A stack in reasonable structural condition is quicker and simpler to take down than one that has been patched, re-rendered, or repointed multiple times with hard cement mortar. Hard cement repointing - common from the 1970s onwards - can make the brickwork difficult to dismantle cleanly and may require mechanical cutting equipment, which adds time to the job.
If the existing flashing has been leaking, there may be damage to the roof structure beneath - battens, felt, or even rafters. Replacing a section of damaged batten adds a relatively small amount to the cost, but if water has tracked further and damaged the felt or the structural timbers, that work needs to be done and will increase the overall price. A proper survey before quoting should identify this, rather than it appearing as an unexpected extra once work has begun.
Re-tiling the area of roof where the chimney stood is included in any properly priced chimney take-down. But the type of tile used affects the cost.
Reclaimed tiles - particularly old clay plain tiles - are more expensive than new budget concrete tiles, and sourcing them takes effort. A salvage yard or reclamation merchant needs to be found with matching stock, and the tiles need to be inspected before purchase. This time and material cost is reflected in the price.
New tiles are cheaper to source but may not match well on older properties. The decision about which route to take is partly about budget and partly about how visible the finished area will be. A rear slope on a property with a low-pitched roof is different from a prominent front-facing pitch visible from the street.
If tile matching is important to you, discuss it specifically when getting quotes. A roofer who says they'll just use whatever they have in the van is not the right person for this job.
Chimney demolition generates a significant volume of rubble. A single-flue stack on a two-storey house will typically produce enough brickwork and mortar rubble to fill a third of a standard builders' skip. Waste disposal must be included in the price and carried out responsibly.
Some contractors charge waste removal separately. Others include it in the overall price. Make sure you're clear which approach applies when comparing quotes - a headline price that excludes skip hire can look competitive but ends up more expensive once waste costs are added.
Taking the stack down and making the roof watertight is the roofer's job. Sealing the flue at base level, removing the fire surround, making good the chimney breast wall, or boarding out the fireplace opening are separate tasks that fall to a builder or plasterer. These can add £200 to £600 or more depending on how much making-good is needed.
If you want to seal the fireplace opening completely and replaster the chimney breast, factor in that additional cost when budgeting for the project as a whole. It doesn't need to happen at the same time as the roofing work, but it should happen - a redundant flue left open at the base will cause draughts and heat loss.
When you receive a quote for chimney take-down work in Mildenhall, it should clearly set out:
A quote that doesn't address these points leaves you exposed to costs appearing mid-job. Ask for clarification on any item that isn't explicitly covered.
A redundant chimney stack costs money to maintain and creates an ongoing risk of water ingress if the flashing or pointing fails. Against a repair bill that can recur every 5 to 10 years on an ageing stack, a one-off take-down cost of £800 to £1,500 is often the more economical long-term decision. There is no longer a structure above the roof line to collect water, crack in frost, or require periodic repointing.
It's a practical calculation, not a guaranteed saving - but for most homeowners with a chimney serving no active fireplace, the numbers tend to support removal over repeated repair.
The best way to get an accurate figure is to have the stack assessed in person. Call Brandon Roofers to arrange a chimney survey at your property in Mildenhall. We'll look at the stack properly, identify anything that will affect the cost, and give you a clear picture of what the job involves before you decide anything.
