Professional Chimney Cowl Installation
Across Lanark, Scotland
Prevent bird entry, rain ingress, and downdraughts. Over 40 years' experience.

One of the most common issues we encounter in South Lanarkshire is birds, particularly jackdaws, choosing to nest inside open chimney pots. This isn't just a nuisance; a blocked flue can lead to dangerous carbon monoxide build-up and poses a significant fire risk if you use an open fire or stove. Our bird guard installations provide a simple and effective barrier.We supply and fit robust mesh guards that prevent birds, squirrels, and large debris from entering your chimney while allowing smoke and gases to escape freely. By installing a bird guard now, you can avoid the hassle and expense of professional nest removal and ensure your home remains safe and clear throughout the nesting season.

Water ingress is a leading cause of damp problems inside the home. When rain falls directly down an unprotected chimney flue, it can saturate the internal masonry, leading to damp patches on chimney breasts, damaged plasterwork, and even structural rot. In a climate as wet as ours, a chimney cap or cowl is an essential investment for any property.Our team installs weather-shielding cowls designed to deflect rain away from the flue opening. This keeps your chimney dry, preserves the integrity of your internal plastering, and prevents the 'sooty smell' that often occurs when water mixes with old soot deposits inside the stack. We assess your specific chimney type to recommend the best capping solution for maximum protection.

If you find that smoke is blowing back into your room or your fire is difficult to light on windy days, you likely have a downdraught problem. This often happens when wind is diverted down the chimney by surrounding trees or higher buildings. An anti-downdraught cowl is specifically engineered to aerate the flue and use the wind to create an upward pull, rather than a downward push.At Gordon Gardiner Slater & Plasterer, we help you identify the cause of poor draw and install the correct specialist cowl to fix it. These fittings are designed to work effectively even in high-wind areas across Lanark and the surrounding hills, ensuring your fireplace or wood burner operates safely and efficiently regardless of the weather outside.

Installing a chimney cowl requires working at height and often involves navigating fragile roof tiles or slates. It is a job best left to the professionals. Our time-served tradesmen are fully insured and have the right equipment to access your chimney stack safely and complete the installation without risking damage to your roof.We don't believe in one-size-fits-all solutions. Every chimney is different, and we take the time to ensure the cowl we fit is the right size and type for your flue. From secure bolt-on cowls to strap-fixed models for older pots, we ensure a perfect, wind-resistant fit that will stand the test of time. You can trust our four decades of local experience to get the job done right the first time.
