Chimney Repairs 

🔧 Our Chimney Repair Services

Chimneys are often the most exposed part of any building, bearing the brunt of weathering, frost action, and thermal movement. If left unchecked, damage can lead to serious water ingress, structural instability, or flue performance issues. We offer the following core chimney repair services in Dundee:

✅ Chimney Repointing (Lime or Cement Mortar)

We carry out chimney repointing using appropriate mortar types based on your property’s construction. For heritage buildings, we are highly experienced in the application of lime mortar, helping preserve breathability and historical integrity. Our pointing methods ensure long-lasting resistance to wind-driven rain and frost damage.

✅ Chimney Flashing Replacement and Lead Trays

Defective flashings are a common cause of roof leaks. We offer full lead flashing replacements in accordance with BS6915 and can also install lead trays at the base of chimney stacks where damp penetration is a recurring issue. All leadwork is completed to LSTA guidelines using Code 4 or Code 5 lead as appropriate.

✅ Chimney Flaunchings and Haunchings

We repair and re-cast launchings and haunchings, which are crucial to keeping chimney pots stable and watertight. These protective cappings are prone to cracking over time but can be restored using high-performance materials.

✅ Chimney Pot Replacement and Terminals

Where chimney pots are damaged or missing, we can supply and install replacement chimney pots sourced from The Reclaimed Company®, helping maintain the visual harmony of your property. We can also fit appropriate terminals and cowls to support ventilation or ensure safe use with solid fuel appliances.

✅ Chimney Stack Waterproofing

For long-term protection, we offer chimney stack waterproofing using industry-approved products like Belzona 5122, a microporous, breathable surface treatment that guards against driving rain while allowing moisture vapour to escape. This treatment can prevent saturation and frost damage without affecting the stack’s appearance.

🔥 Solid Fuel Chimney Work – With Trusted Advice from Hot Box ® Stoves

Where chimneys are connected to solid fuel appliances, we work in close consultation with trusted partners such as Hot Box® Stoves. Their expert team provides input on chimney flue sizing, capping solutions, ventilation, and compliance with Building Regulations Part J to ensure any work we carry out is fully compliant and suitable for continued use with wood burners, multifuel stoves or open fires.

🏗️ Full Access & Scaffold Solutions Included

Our chimney repairs include all access requirements, whether via scaffold towers, full perimeter scaffolding, or platform lifts. Safety and compliance are built into our method statements and risk assessments, and we’re fully insured for all working-at-height operations.

🎯 Why Consider a Full Chimney Stack Assessment?

In many cases, addressing one issue (e.g. leaking flashings) without checking the entire stack is a false economy. That’s why we always recommend a comprehensive chimney survey, especially for older properties. We check:

• Brickwork condition
• Pointing and mortar stability
• Flashings and trays
• Chimney pot and flue condition
• Evidence of damp ingress
• Stack movement or leaning

We can then deliver a detailed plan of action tailored to your building, materials, and intended use.
