Rich finds a lime kiln. Stephen nerds out on chemistry. Somehow, it all makes sense.

In this episode of Talking Conservation, we walk through the full lime cycle — from burnt limestone to breathable lime mortar — and explain why it still matters today.

Packed with practical knowledge, dry humour, and the occasional chemistry flashback, this is your crash course in the building material that’s been quietly doing the heavy lifting for centuries.

Rich comes across an old disused lime kiln and this leads us to discuss the Lime Cycle. Stephen talks about how a source of Calcium Carbonate (e.g. Limestone) is taken through various processes that each change the nature of the material, but that at the end it reverts to a form of Calcium Carbonate again - hence the term Lime Cycle. Rich reflects on this at the end and mentions that we will look at various forms of lime (as used in building works) in a future video.

Douglas Kent is the Technical Secretary ofSPAB, but in his private capacity purchased The Old Sun Inn, Saffron Walden, afew years ago, having previously acquired the neighbouring properties. We talkabout how Douglas got involved in conservation and how he came to the point ofbuying these buildings.  We discuss thechallenges he has so far faced and those he is yet to tackle. Amongst theissues discuss3ed we consider how to undertake appropriate repairs, dealingwith inappropriate past works, upgrading to modern requirements and dealingwith building regulations.  Douglas tellsus about his plans for the future and mentions some of the events lined up.

Buildings Insurance for Historic Homes: Everything You Need to Know

If you're a fan of home renovations, historic properties, or jaw-dropping transformations, you’ve likely heard of Greg—better known on social media as “Man with a Hammer.” In this episode, we dive into his epic journey of restoring the Admiral’s House, a massive 8000-square-foot ex-Naval officer’s quarters in Plymouth, into a stunning forever home.

In this episode we explore what many homeowners have experienced during the purchase process of buying an older property; the dreaded "you require a separate timber/damp survey".

Stephen and Rich discuss the reasons you may get such a requirement, usually from your mortgage lender, the history that surrounds it and finally what people can do about it to ensure you both satisfy the lending conditions but also do what is appropriate for your home.

Thanks for listening.

MYTHBUSTING!

James Wright

We are talking to James Wright - the Historic Buildings Mythbuster!

We start off by looking into his background and how he got into building archaeology, and then we go on to tease a bit more out about him in terms of some of the grand buildings he's dealt with to some of the smaller historic buildings, and the lessons that he's learnt from those. We talk about some of the science involved in building archaeology, so dendrochronology what it is, how that works and how he uses that, as well as some of the other investigation techniques and the technology that's used.

The historic reuse of building materials is discussed and how that can throw you off the scent of a particular building in terms of it’s age and legacy. From this we go ont to talk about where to start with understanding your own building and some of the resources that homeowners can use to research their own building's history.

Then, onto the myths. In particular we talk about the myth of reusing ship timbers, as well as touching on the issue of the oldest pub.

And then James mentions his favourite books, including Linda Hall’s ‘Period House Fixtures & Fittings’. When we go on to talk about his favourite building, we benefit from a fantastic overview of the history of Knole House in Kent.

Of course, we mention how to contact James.

We think it's a really good episode, this one, very engaging, hope you enjoy it, do let us know.

We discuss Ben winning a Blue Peter competition, getting his neighbours to work on his house, and painting a room for 50p! On a more serious note, we talk about lime, hot lime, Naturally Hydraulic Lime, training, and innovation. Ben is keen to help train the next generation of plasterers, but also homeowners wanting to have a go themselves, and professionals wanting to understand the use of lime better.
