Ask three roofers what it costs to repoint a chimney and you may get three very different numbers. That is not always because someone is trying it on: access, stack size and the state of the brickwork genuinely change the job. Here is how the pricing works, so you can read a quote properly instead of just picking the cheapest one.
For a standard two storey house in Newark, Lincoln or the surrounding villages, repointing a single chimney stack typically lands somewhere between £600 and £1,400. That usually covers scaffolding or a tower, raking out the old mortar, repointing all four faces and re-bedding the flaunching around the pots.
Below roughly £500 you are usually looking at a ladder job with a quick smear of mortar over the top of the old joints. That is not repointing, and it tends to fail within a couple of winters. Above £1,500 there is normally a reason: a tall stack, a steep or fragile roof, a mid-terrace with awkward access, or a chimney that needs partial rebuilding rather than pointing.
Access is the single biggest variable. A stack on a bungalow gable is a different day's work to one in the middle of a Victorian terrace roof in Newark town centre, where the scaffold has to be designed around the neighbours and possibly a pavement licence.
Stack size matters more than people expect. A small single flue stack might be eight or nine courses of brick; a big double flue Victorian stack can be three times the surface area, so it is three times the raking out and three times the pointing.
The mortar mix should also change the price conversation. A lot of older properties around Lincolnshire and the Trent villages are built with soft red brick or limestone and want a lime based mortar. Hard cement pointing on soft brick looks tidy for a season, then traps moisture and starts blowing the faces off the bricks. Lime work is slower and costs a little more, and on the right building it is the only sensible option.
Repointing only fixes the joints. If the bricks themselves are spalling, if the stack leans, or if you can rock the top courses by hand, pointing over the top is money wasted. In that case you are looking at a rebuild from the roofline up, which for a typical stack runs from around £1,200 to £2,500 including scaffold, new flaunching and reusing sound pots.
A few things you can check from the ground with binoculars before anyone comes out: mortar joints that have receded more than about 10mm, vegetation growing out of the stack, cracked or lifting flaunching around the pots, and dark damp staining on the chimney breast in the bedroom or loft. Damp appearing on an internal chimney breast after driving rain from the west is a classic sign that the stack is taking on water.
Ask every roofer to price the same scope in writing. Vague quotes are where the trouble starts, because two prices for what look like the same job can quietly include very different work.
Also ask when they intend to do it. Repointing needs mortar to cure without freezing, so work through a hard Nottinghamshire winter is best delayed. Late spring through autumn is the sensible window, and a reputable roofer will tell you that rather than take the deposit in January.
Properly raked out and repointed with the right mix, expect 20 to 30 years on a sheltered stack. An exposed stack catching the prevailing wind and rain may need attention sooner, and a smeared-over job may not see out five winters.
For anything beyond a quick look, scaffolding or a properly footed tower is the safe and correct approach, because repointing means working with both hands on a stack for a full day or more. Ladder-only pricing is usually a sign that corners are being cut elsewhere too.
Generally not, as repointing is treated as maintenance rather than sudden damage. If a storm has brought pots down or shifted the stack, that is more likely to be a valid claim, so photograph the damage before any work starts.
