The cost of a chimney repair can vary depending on the extent of the damage and the specific repairs needed. In the UK, the average cost for chimney repairs ranges from £300 to £1,000. However, the final cost will depend on factors such as the type of repairs required (e.g., repointing, flashing replacement, chimney cap installation), the accessibility of the chimney, and the labour costs of the contractor. It’s advisable to obtain quotes from multiple chimney repair specialists like JB Roofing (Cambs) Ltd to get an accurate price based on your specific repair needs.

Also known as ‘benching’, chimney flaunching is a term that refers to the strong mortar mix that holds your chimney pots in place. The flaunching on your chimney provides a tough waterproof barrier to keep the interior of your chimney and your home dry.

Chimney flashing is normally the leadwork or roof flashing that creates a waterproof seal to protect your chimney and roof from water damage and penetration.

Professional roofers or roofing contractors have the necessary experience to repoint your chimney properly so it will last many more years. If you do this early enough, the repairs will be minor, and it will simply be a matter of pulling out the old mortar and putting in the new.

If you notice that the mortar on your chimney has changed colour, it is a sign that the mortar and bricks are old and need repointing. If the mortar has started to flake or chip off, this can also mean that the mortar has gone brittle and become weak.

When a chimney develops damaged joints, allowing moisture entry, it is recommended to remove the damaged portions and replace them with proper materials. This repair is known as repointing.

Over time, the bricks and mortar joints in most chimneys begin to deteriorate. Unfortunately, chimney deterioration is a natural process due to exposure to the elements, such as rain, snow, ice and winds. These elements can impact the chimney from all directions, so deterioration is often inevitable.
