Chimney Repointing in Dartford – Stop Leaks Before They Worsen

If your chimney mortar is cracking or crumbling, it’s time to act. Weather and age can wear down the joints that hold your chimney together, letting water in and weakening the structure. S Harris Roofing offers professional chimney repointing in Dartford to restore strength, prevent leaks, and extend the life of your roofline.

Why Chimney Repointing Matters

Mortar joints protect the brickwork from water penetration. When they fail, moisture seeps in, leading to internal damp, frost damage, and even chimney instability. Repointing replaces the old, damaged mortar with fresh, properly mixed material to keep your chimney weatherproof and structurally sound.

How Much Does Chimney Repointing Cost in Dartford?

Most chimney repointing jobs in Dartford fall between £350 and £1,100, depending on size, height, and condition. Small patch repairs are cheaper, while full four-face repointing on a tall stack can reach the upper end of that range.

Minor repointing (1–2 faces): £350 – £500
Full stack repointing: £600 – £1,100
Repointing with new lead flashing: £800 – £1,400

Chimney Repointing FAQs

How do I know if my chimney needs repointing?

Look for crumbling mortar, visible gaps between bricks, or vegetation growing out of joints. These are signs the mortar has failed and needs replacing.

Can you repoint just one side of a chimney?

Yes. We can target only the weathered faces if the rest is still sound. It’s a cost-effective solution when damage is localised.

How long does chimney repointing take?

Most repointing jobs are completed in one to two days, depending on the size and height of the stack.

Does repointing stop chimney leaks?

It often does, but if lead flashing or haunching is also failing, we’ll repair those at the same time to guarantee a watertight result.

What type of mortar do you use?

We match the original mortar as closely as possible — using lime mortar for older properties and modern mixes where appropriate.

Do you provide a warranty on chimney repointing?

Yes, all repointing and associated repairs come with a written workmanship guarantee for your peace of mind.

Can you repoint during winter?

Yes, as long as the temperature stays above freezing and conditions are dry. We plan around weather for proper curing.
