Minor repair or full renovation
A minor repair is sufficient when
The flue interior is sealed and smooth, confirmed by a camera inspection.
Only the repointing or the chimney stack flashing above the roof is weathered.
The draught is good and there is no smell of smoke inside the house.
You only want to refresh the chimney aesthetically.
A full renovation is required when
The camera reveals cracks, loose mortar joints, or internal soot damage.
You are switching from an open fireplace to a closed stove or pellet stove.
Tar or condensation stains appear on the chimney breast inside your home.
The chimney has previously suffered a chimney fire.
Start with a camera inspection costing 100 to 200 euros before making a decision: that way you never pay for a renovation you do not need.
How a chimney renovation works in 5 steps
Chimney camera inspection: clear visual insight into flue condition, diameter, and obstacles.
Exterior repairs: restoring the stack, mortar joints, and flashing to prevent water ingress.
Installing a flexible stainless steel liner matched to your appliance diameter, typically 150 to 180 millimetres.
Connecting and insulating around the liner, finished with a chimney top plate.
Test burn, draught measurement, and certification for your insurance provider.
An average renovation takes 1 to 2 working days: exterior repairs on day 1, lining installation and test burn on day 2. Schedule the work outside the heating season to benefit from waiting times of 1 to 2 weeks instead of 4 to 6 weeks.
Discover exactly when a flue liner is required in our guide on flexible stainless steel liners in existing chimneys. Warning signs indicating damage can be found in signs of a dirty chimney.
DIY or professional installation
Repointing and fitting new flashing are manageable DIY projects with safe roof access, and materials such as cowls and top plates are available in our webshop. Pulling the liner, creating airtight connections, and issuing compliance certificates require professional expertise, ensuring you receive the certificate your insurer demands.
If the flue proves beyond repair, compare costs for a completely new flue installation in what a new flue costs per situation. Official technical regulations for heating appliances and flues can be found on the Buildwise standards page.
Key points to consider
Do not wait for the heating season: waiting times are 1 to 2 weeks shorter between April and September.
Combine your chimney renovation with your annual sweeping service of 60 to 90 euros in a single appointment.
Always request the certificate after completion, as home insurers typically ask for the last 2 certificates.
A neglected chimney significantly increases the risk of a chimney fire, with potential damage running into thousands of euros.
Always arrange a full inspection following a chimney fire before using the appliance again.
