Lime Mortar Details That Matter – Drip Detailing, Exposure & High-Level Repairs

About this episode

This episode discusses the importance of drip detailing and high-level repairs in preserving historic buildings, featuring insights from heritage mason Steve Hogarth.

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.
