Chimney Repairs in Sunbury-On-Thames, Surrey

Most chimney problems start with the mortar. Over decades of exposure to wind and rain, the mortar between your bricks naturally begins to crumble and wash away. If you can see gaps or loose grit in your gutters, it's a sign that your chimney needs some attention. We specialise in chimney repointing, where we carefully rake out the old, failing mortar and replace it with high-quality, weather-resistant materials. It's not just about looks; it's about restoring the structural integrity of the stack. By catching this early, you prevent water from soaking into the bricks, which often leads to expensive 'freeze-thaw' damage where the brick faces actually start to pop off.

Where your chimney meets your roof tiles is the most vulnerable point for water ingress. This gap is bridged by lead flashing, which acts as a waterproof seal. However, lead expands and contracts with the changing Surrey temperatures, and over time, it can crack or pull away from the brickwork. If you've noticed a leak during a heavy downpour, the flashing is usually the first place we look. Our team are experts in leadwork, ensuring that every piece is correctly 'stepped' into the mortar joints and sealed properly. It’s a bit of a lost art, but getting it right means your home stays bone-dry for decades to come. We don't believe in quick-fix tapes or sealants; we do the job properly with durable materials that last.

The 'flaunching'—that's the sloped bed of concrete at the very top of your chimney that holds the pots in place—takes the brunt of the weather. Because it’s so exposed, it often cracks, allowing water to seep down into the heart of the chimney breast. This can lead to soot staining on your internal walls, which is a real headache to clean. We can strip back that old, cracked concrete and apply a fresh, smooth bed of flaunching that sheds water efficiently. While we're up there, we'll check your chimney pots too. If they're cracked or loose, we can replace them or re-seat them safely, so you don't have to worry the next time a storm rolls through Spelthorne.

Living near the Thames means we have plenty of local birdlife, and they love nothing more than nesting in a warm, quiet chimney. A blocked flue isn't just a nuisance; it's a serious safety risk if you use your fireplace, as it can cause carbon monoxide to back up into your living room. We install a range of chimney cowls and bird guards that stop Jackdaws and other birds from moving in. These cowls also help with downdraughts—those annoying puffs of smoke that come back into the room on windy days—and prevent rain from falling directly down the flue. It’s a simple, cost-effective bit of maintenance that saves a lot of trouble in the long run.
