What’s the biggest threat to your historic building? Water.
In this special episode of Talking Conservation, we’re joined by Steve Hogarth — SPAB Fellow, heritage mason, and rope access conservator with Highlife Rope Access — to explore how the smallest details up high can make the biggest difference to your building’s long-term health.
We dig into:
- Why effective drip detailing is critical to keeping water off your building
- What causes damage when high-level details are missing or poorly repaired
- Sky-facing joints and how they differ from vertical surfaces
- How to assess and choose the right lime mortar mix for exposed locations
- The overlooked genius of traditional detailing (like string courses, throatings & hood moulds)
- When to use NHL, hot lime, or natural cements- Why small targeted maintenance can prevent costly full-scale repairs
- Real-world insight from Steve’s rope access conservation work on churches and historic buildings
This is an essential listen for homeowners, tradespeople, or professionals working with older or listed buildings.
