Chimneys take a beating over the years. Wind, rain, frost, and general wear can really affect the brickwork and pointing. If cracks start to show or mortar begins to crumble, it’s not just about appearance — it can lead to more serious problems. At Collective Roofing, we provide chimney repairs and repointing services that help protect your home and keep everything working as it should.
When the pointing between the bricks breaks down, water can start to get in. Once that happens, things can move fast — especially in winter when moisture freezes and expands. Before you know it, the structure becomes unstable, and tiles, flashing, or even parts of the chimney itself can loosen. That’s where we come in. We deal with these problems every day and know how to sort them before they cause lasting damage.
Sometimes the repair is minor — just a few bricks that need attention or a bit of re-bedding around the pot. Other times, it might be more involved — full repointing, brick replacement, or rebuilding part of the stack. Either way, we approach every job with care. We look at the condition, check what’s caused the issue, and explain what needs to be done clearly before we get started.
At Collective Roofing, we’ve worked on chimneys of all shapes, sizes, and ages. Whether yours is still in use or just there for appearance, it’s still part of your roof and needs to be safe and sound. We’ll make sure it stays that way — without stress or delay.
Chimney work isn’t just another job. It’s up high, it’s exposed, and it involves materials that have aged with the building. You need someone who understands how it all fits together and won’t treat the work like a quick fix. At Collective Roofing, we focus on doing things properly — not rushed or patched, but carefully and thoroughly.
Here’s what sets us apart:
It’s all about understanding what the chimney needs — and getting it sorted before it becomes a bigger issue.
Chimney problems aren’t always obvious right away. You might not even notice them until you’ve had a bit of bad weather or someone spots something from the ground. But when mortar starts to go, or bricks begin to move, things can escalate fast. Knowing when to get it looked at makes a big difference.
Here are some signs it might be time for repairs or repointing:
If you’ve seen any of those signs — or just want to get ahead of potential problems — give us a call. We’ll have a proper look and tell you exactly what’s going on.
Working on chimneys brings a few more risks than your average roofing job. They’re usually the highest point on the building, and the brickwork can be unstable if it’s been left too long. That’s why we treat safety as a priority every time we take on this kind of work. At Collective Roofing, we follow all UK health and safety regulations — including the latest guidance from the Health and Safety Executive.
Before we begin, we carry out a full risk assessment. That includes checking the height, condition of the chimney, roof pitch, and access points. If scaffolding is needed, we’ll arrange for that to be set up securely before any work begins. Chimney work often involves dust, debris, or working with damaged materials — so we make sure the area below is protected and clear too.
We also think about the weather. Rain, frost, or high winds can affect how safely we can work — especially on exposed ridges or stacks. If it’s not safe, we won’t start until conditions are right. And when we do begin, every step is handled with proper equipment and a clear plan.
This isn’t just about rules — it’s about working in a way that keeps you, your property, and our team safe. No rushed jobs, no shortcuts. Just a solid, careful approach that respects your home and gets the work done the right way.
Chimneys on commercial properties often get overlooked — especially if the building’s been modernised or the chimney’s no longer in use. But whether the chimney is active or purely structural, it still plays a part in keeping the building watertight and looking presentable. At Collective Roofing, we carry out chimney repairs and repointing across a wide range of commercial sites — from listed buildings to schools, office blocks, and retail units.
Commercial chimney work can vary a lot. Some jobs involve heritage buildings with period brickwork, where care needs to be taken to match materials. Others are more modern setups, where the stack needs resealing or removing entirely. Whatever the situation, we take the time to understand the structure, what it’s there for, and how best to carry out the work without causing disruption.
We provide:
Jobs are planned around your business or site hours, and we coordinate with facilities teams or contractors when needed. All work is documented with clear reporting, before-and-after photos, and follow-up advice. If you’re managing a commercial building and need to keep the roof and structure in good condition, chimney work is something worth staying ahead of — and that’s where we can help.
If your chimney’s showing signs of wear, or if you’re just unsure whether it’s still in good shape, now’s the time to have it looked at. At Collective Roofing, we make it easy. We’ll inspect the chimney, explain exactly what’s going on, and talk you through what needs doing — without pressure or confusion.
Whether it’s small repairs, full repointing, or a complete rebuild, we’ll handle it properly from the first visit to the last brick. Call us on 020 8226 4827 and let’s get your chimney sorted before the damage spreads.
