How Much Does It Cost to Repoint a Chimney?
£300 – £1,200
per chimney
Repointing a chimney costs between £300 and £1,200 depending on the size of the chimney stack, the amount of mortar that needs raking out and replacing, and the scaffolding cost. Chimneys are exposed to freeze-thaw cycles and driving rain that gradually erode the mortar joints, and repointing every 15-20 years is recommended to prevent water ingress.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Stack size - a small single flue chimney costs less to repoint than a large double or triple flue stack
Mortar condition - if joints are deeply eroded or need significant raking out, the job takes longer
Mortar type - standard sand and cement is cheapest; lime mortar for older properties costs more but is the correct choice for softer Victorian bricks
Scaffolding - always required for chimney repointing and adds £600-£1,500 to the project
Labour vs materials
Repointing a chimney typically takes one to two days. Labour accounts for around 40-50% of the total cost; scaffolding and mortar materials make up the rest.
Repair or replace?
If the brick faces are heavily spalled or the stack is leaning or cracked, repointing alone will not solve the underlying problem. A structural assessment by a roofer or surveyor is recommended before committing to repointing costs.
