Chimney Repairs in Farnham, Surrey

Most homeowners we speak to in Farnham are surprised by how much damage a simple frost can do to their chimney. When the mortar between your bricks starts to crumble or erode, we call it weathering. This isn't just an aesthetic issue; it actually weakens the structural integrity of the whole stack. Our team specialise in repointing, which involves carefully scraping back the old, failing mortar and replacing it with a fresh, durable mix. This stops bricks from coming loose and prevents water from soaking into the masonry. We make sure the new mortar matches the look of your existing brickwork, so the repair is as subtle as it is strong. It's a simple way to add years of life to your chimney without the cost of a full rebuild.

One of the most common reasons people call us out is a damp patch appearing on an upstairs ceiling. More often than not, the culprit is the lead flashing. This is the waterproof seal that sits where your chimney meets the roof tiles. Over time, lead can crack or pull away from the brickwork due to thermal expansion—that’s just a way of saying it moves as it heats up and cools down. If it isn't fitted perfectly, you’ll end up with water ingress. We’re experts at repairing and replacing leadwork, ensuring everything is tucked in and sealed correctly. We don’t believe in quick fixes that fail after a few months; we use premium materials to make sure your home stays dry even during the heaviest Waverley downpours.

The very top of your chimney, known as the flaunching, is like a cement hat that holds your chimney pots in place. Because it’s so high up, it takes a real beating from the frost and sun, which leads to cracks. If that cement starts to break apart, your pots can become unstable, which is a serious safety risk. While we're up there, we can also fit chimney cowls or bird guards. Have you ever been woken up by the sound of birds nesting in your flue? It's a common problem in leafy areas like Farnham and Tilford. Installing a simple bird guard keeps the wildlife out and stops rain from falling straight down the chimney, while still letting your fireplace or boiler breathe properly.

Sometimes, a chimney has reached the point where a few repairs just won't cut it. If the mid-feather—the internal wall between flues—has collapsed, or if the stack is leaning dangerously, a rebuild is often the safest option. We’ve handled countless stack rebuilds across Surrey, from small cottage stacks to larger chimneys on detached properties. On the other hand, if you’ve modernised your home and no longer use your fireplace, you might consider a chimney removal. This can free up space and get rid of a potential maintenance headache. We handle the whole process safely, ensuring your roof is tiled over seamlessly so you’d never even know the stack was there. Whatever your situation, we'll give you honest advice on the most cost-effective path forward.
