Expert Chimney Repairs in South London
From repointing crumbling mortar to replacing damaged lead flashing, HLS Roofing provides specialist chimney maintenance to keep your home safe and watertight.
Why Chimney Maintenance is Critical
Your chimney stack is completely exposed to the elements. It takes the full force of South London's high winds, driving rain, freezing winter frost, and scorching summer sun. Over time, this extreme exposure causes the mortar to degrade, the lead to split, and the brickwork to become unstable.
A damaged chimney isn't just a cosmetic issue. It is one of the most common causes of penetrating damp in period properties across Croydon, Bromley, and Surrey. If left unchecked, a neglected chimney can even become a structural hazard, risking collapse during a severe storm.
Our Comprehensive Chimney Services
At HLS Roofing, our team is highly experienced in repairing, restoring, and removing chimney stacks on all types of properties. Here is what we do:
1. Chimney Repointing
The mortar joints between your chimney's bricks will naturally weather and crumble over the decades. This allows rainwater to seep directly into the brickwork. We carefully grind out the old, failing mortar and professionally repoint the stack, restoring its structural integrity and weatherproofing.
2. Lead Flashing Repairs & Replacement
The joint where your chimney meets the roof tiles is the most vulnerable point for leaks. This gap is sealed with lead flashing. As lead ages, it can split, or the mortar holding it in the brickwork can fail. We specialize in dressing and installing new code-compliant leadwork to create an impenetrable, watertight seal.
3. Chimney Flaunching
Flaunching is the strong cement bed at the very top of your chimney that holds the chimney pots in place and sheds rainwater away from the flue. When flaunching cracks due to frost, water gets inside the stack and the pots become loose. We can hack off the old, degraded cement and install a fresh, durable flaunching bed.
4. Pot Replacement, Capping & Cowls
Whether you need a broken chimney pot replaced, a disused flue securely capped off to stop rain and drafts, or a bird-guard cowl installed to prevent nesting, we have the right solution for your chimney.
5. Chimney Removals & Reductions
If your chimney is no longer in use, structurally unsafe, or you simply want to free up space in your loft, we offer safe and efficient chimney reduction or complete removal services, making the roof good with matching tiles afterwards.
Chimney Repair FAQs
How do I know if my chimney needs repointing?
If you can see gaps between the bricks, if the mortar looks powdery or is actively falling onto your roof or patio, or if you have damp patches on the chimney breast inside your house, you almost certainly need repointing.
Do you need scaffolding to repair a chimney?
In most cases, yes. Chimneys are located at the highest and most difficult-to-reach parts of the roof. For the safety of our team and to ensure the work is done to the highest standard, proper access equipment or scaffolding is usually required.
My chimney is leaning. Is it dangerous?
Yes. A leaning chimney stack is a major structural hazard and could collapse during high winds, causing catastrophic damage to your roof or anything below. You should contact us immediately for an urgent safety assessment.
