Why Chimneys Need Special Attention
Chimneys sit at the highest, windiest point of the roof, so rain, frost and gusts hit them harder than anything else on the house. In Flintshire the first signs are usually crumbling pointing and a lifting lead flashing, and by the time a stain appears on an upstairs wall the water has often been getting in for a while.
Small chimney problems are often missed until they’ve caused damp or damage inside the property – regular attention keeps it that way rather than the alternative.
Repointing, flashings, rebuilds and capping: we deal with chimneys of all types, and can remove a disused stack if you would rather it were gone.
Chimney Repairs in Flintshire: What Local Properties Need
From the older brick and stone houses of Mold and Holywell to the estates around Buckley, Flint and Deeside, chimneys across Flintshire face constant wind and rain, and exposed stacks suffer in particular. Crumbling mortar, loose pots and failing flashing are the usual culprits when damp appears around a chimney breast.
We can inspect the stack, explain what needs doing and carry out the work, whether that is repointing, new flashing, a rebuild or capping off a chimney that is no longer in use.
Repointing & Brickwork
Mortar erodes faster than brick in rain and frost. When pointing starts to crumble on a Flintshire stack, water gets into the joints and can start to loosen bricks, so repointing early is the cheap way of saving the whole stack.

- Spalled & damaged brick replacement
- Chimney pot repair & replacement
Lead Flashing Repairs
Flashing is the strip of lead that keeps the join between chimney and roof watertight. In Flintshire it commonly fails where the lead has aged and the mortar holding it in the chase has crumbled, so it lifts and lets water in at the weakest point.

- Flashing chase repointing
- Leak diagnosis around the chimney
Our Chimney Repair Services
Our Chimney Repair Process
Chimney Inspection
We check the stack, pots, mortar joints and flashing for signs of wear, damage or leaning, both from the roof and from inside where visible.
Honest Recommendation
We advise whether repointing or a flashing repair will solve the problem, or whether more significant work such as a rebuild is genuinely needed.
Repair Or Rebuild
Your chimney is repointed, re-flashed, or – where the stack is structurally compromised – safely rebuilt using matching brick and mortar.
Final Check
We check the completed work is sound, weathertight and finished neatly before we consider the job done.

Exposed Stacks In Flintshire
Chimneys on the higher, more open ground around Flintshire take the full force of the weather. Lead flashing and pointing are usually the first things to fail, so that is where we start the inspection.
Chimney Repairs In Flintshire's Towns And Villages
Many Flintshire homes, from older terraces in Buckley and Flint to village properties around Hawarden and Hope, still have working or retired chimney stacks. Weathered pointing, failed flashings and loose pots are the most common reasons we get called out.
In Mold, Holywell and the villages, older buildings may have tall, exposed stacks that take a lot of weather. We repoint, repair lead flashings and rebuild where needed, and we will tell you plainly if a stack can be repaired or if rebuilding is the better value.

Frequently Asked Questions
How do I know if my chimney needs repairing?
Warning signs include a leaning stack, loose or cracked pots, pointing that has gone soft or fallen out, flaking bricks, and damp patches on the chimney breast or ceiling nearby. Spotting one of these early in a Flintshire home usually keeps the repair small.
What is chimney flashing and why does it fail?
Flashing usually fails because the lead has aged and moved, the mortar around it has crumbled and released it, or it has gradually worked loose in the wind. Around Flintshire stacks, that is the most frequent reason we are asked to trace a leak.
Does my chimney need repointing, or a full rebuild?
If the bricks are sound and only the mortar has worn, repointing is usually the answer. If the stack is leaning, the brick faces are breaking up or there is clear movement, a rebuild becomes necessary. We will inspect it and give you a straight recommendation.
Can you remove or cap a chimney that’s no longer used?
Yes. We can cap a disused chimney with a vented cover, which stops water and birds getting in while keeping air flowing, or remove it down to the roofline or lower. We will explain what removal involves for your particular Flintshire house before you decide.
Do you offer a guarantee on chimney repair work?
Yes, all our chimney work is guaranteed. Get in touch for the specific terms that apply to your job, as this can depend on the type and scale of the work involved.
How much does chimney repair work cost?
A small repoint costs far less than a rebuild, and access and condition also affect the price. We quote free and without obligation, so you get an accurate figure for your Flintshire chimney before you commit to anything.
