Hi, I’m Adam. Based in Devon, I’ve been working with traditional lime mortars and lime plasters since my late teens. What began as a trade quickly became a genuine passion for historic buildings, traditional craftsmanship, and the materials that have protected our built heritage for centuries.
Today, I specialise in traditional lime pointing, internal and external lime plastering, cob repairs, and timber lintel replacements for period, listed, and traditionally constructed properties throughout Devon and the surrounding counties.
I believe older buildings deserve sympathetic repairs using compatible materials and traditional techniques. Whether I’m restoring historic cob, applying a multi-coat lime plaster system, repointing masonry, or carrying out structural lintel replacements, my focus is always on preserving the character, performance, and longevity of the building.
If it involves traditional lime or historic masonry work, chances are I’ll be happy to help.

Devon is home to unique historic architecture, from classic cob cottages to rustic stone farmhouses. Because these solid-wall properties were originally built to manage moisture naturally, lime plasters and mortars are the only compatible choice when carrying out repairs or maintenance. Modern cement traps damp inside walls, leading to severe moisture issues and cob deterioration. Lime, by contrast, lets the building breathe—an absolute necessity in Devon’s damp maritime climate.
Lime is also inherently flexible, allowing older buildings to move and settle without cracking surrounding masonry or cobwork. By accommodating natural movement and drawing out moisture, lime preserves structural integrity and authentic character. For period and listed properties throughout Devon, lime isn’t just an aesthetic preference—it’s vital for the health of the building.
From transforming just one problematic wall in a thatched cob cottage in Tavistock through to complete lime restoration projects for country estates around Totnes, we handle a wide variety of work across Devon. Here’s what clients have to say about working with us!

Adam and his team did a fantastic job insulating and plastering the upstairs of our old house. Knowledge was good, communications strong and all left clean and tidy at the end. We will definitely be having them back later in the year when we move on to getting the downstairs done.Posted on Google![]()

Adam and his team were really hard working, efficient and tidy. They arrived on time on every visit. They left the room tidy after each work session. They are very pleasant and friendly. They have totally transformed a very tired bedroom that had had terrible things done to it over the years such as wallpaper applied to the lime plastered walls and ceiling. We can now complete the transformation by sanding the floorboards and decorating. Can highly recommend them.Posted on Google![]()

Review from: Jo May Adam and his team completed an interior and exterior lime rendering job for me over the summer 2025. Adam was possibly the most reliable tradesman I’ve ever dealt with. Kept in touch, turned up and completed the job in the time specified and helped me trouble shoot anything that came up. I am really really pleased with the work and have had many compliments from other people. No hesitation in recommending Thorne’s plastering traditional specialists.Posted on Google![]()

Adam, Mike and Paul have done a fantastic job on our Grade 2 listed house. Old concrete render removed and re-rendered in lime. Thoroughly professional, knowledgeable and willing to go that extra yard to produce a fantastic finish on the place at a fair price. Thanks Adam, we will be looking to use your skills againPosted on Google![]()

It was very apparent from the day he arrived to quote that Adam has a huge amount of knowledge and experience in working on older properties. Right from the start I was filled with confidence in his abilities and this was further established on the day the team arrived to start work on the project. Adam and his team were pleasant, friendly, punctual, hard working and tidy. Adam was prompt with answering messages and communicated well on my queries regarding the work. He gave me reassurances that any additional work, regarding issues found, would be discussed and priced before continuing. Thankfully no additional work was needed and the final price was exactly as quoted. In essence, Thorne's Plastering did an excellent job taking old plaster back to cob and applying lime plaster in our 300 year old cottage and delivered a great quality of work. We would highly recommend these guys and look forward to working with them again.Posted on Google![]()

We wouldn’t hesitate to recommend Thornes plastering. We met Adam and his team during the renovation of our stone and cob cottage. They did some plastering but also some more structural work replacing some oak lintels and repairing a crack in the cob. You couldn’t meet a nicer team and we will definitely be using them again.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

While many plasterers offer lime as an additional service, lime work is at the heart of everything I do. I have dedicated years to understanding traditional materials, historic building methods and the correct techniques required to repair and preserve older properties.
From traditional three-coat non-hydraulic lime plastering and lime pointing to stonework repairs heritage building work my focus has always been on delivering sympathetic workmanship that respects the age and character of the building. I continually invest in expanding my knowledge and work closely with some of the UK’s leading suppliers of traditional building materials, including Mike Wye, Cornish Lime and Best of Lime.
By specialising in lime rather than treating it as an occasional service, I can provide informed advice, appropriate material selection and repairs that work in harmony with traditional buildings. For me, lime isn’t simply a product I use—it’s a craft I’m genuinely passionate about.
Navigating the do’s and dont’s of the lime world can be confusing at first, as well as trying to understand the different types of lime and their applications. I’ve answered some of the commonly asked questions by Devon’s home-owners when it comes to lime plastering & lime pointing and traditional building repairs. If your question isn’t on the list feel free to give me a call and be more than happy to help.
Not always, but it depends on what’s currently on the wall. If your walls have been covered with modern cement render or gypsum plaster, these will need to come off before lime goes on. Cement and gypsum are far too hard and non-breathable to sit alongside lime, and leaving them in place can cause serious moisture problems down the line. Original lime plaster that’s still sound and well-bonded can often stay. I’ll always assess the existing substrate before recommending anything — there’s no point in unnecessary stripping if it isn’t needed.
Lime plaster ‘dries’ (it actually carbonates) significantly slower than modern gypsum — and that’s actually a good thing. Each coat needs time to carbonate (react with CO₂ in the air) before the next goes on. As a rough guide, allow 2–4 weeks between coats depending on the time of year, ventilation, and wall thickness. A full three-coat lime plaster system on a room can take several months to fully cure. It’s a patient process, but the result is a wall that breathes properly and lasts for generations.
Yes — in fact, lime is often the better choice for damp-prone areas in older properties. Unlike gypsum, lime is breathable and naturally resistant to mould. It allows moisture to move through the wall and evaporate rather than trapping it behind an impermeable surface. That said, it’s not a substitute for addressing the root cause of damp — if there’s a structural issue, that should be resolved first. I’ll always flag any underlying concerns before starting work.
No, and it’s an important distinction. Cement mortar is far harder than the stone or brick it sits between, which means any movement causes the masonry itself to crack rather than the joint. In older stone buildings — which are common across Devon — this can lead to serious structural damage over time. Lime mortar is softer and flexible, so it acts as the sacrificial element, protecting the stonework. If your property has been previously pointed with cement, I can remove it carefully and replace it with an appropriate lime mix.
Almost certainly yes — and it’s likely what was originally used. Traditional stone buildings across Devon were built to breathe, using lime throughout. Applying modern materials to these walls is one of the most common causes of damp, spalling stone, and internal condensation. Lime plaster and pointing work with the building’s natural moisture movement rather than against it. If you have an older property and you’re unsure what’s on the walls or what’s causing problems, I’m happy to take a look and give you an honest assessment.
Every job is different — wall condition, accessibility, the number of coats required, and whether any substrate preparation is needed all affect the price. I provide detailed, no-obligation quotes after seeing the job in person. What I can say is that lime work is a specialist trade and the materials are more expensive than modern alternatives, but the longevity and performance of a properly done lime finish more than justifies the investment. I don’t cut corners on materials or preparation.
The general rule is: if your building was constructed before around 1920, it almost certainly needs lime. Properties built with solid stone or brick walls — rather than cavity walls — are designed to manage moisture through the fabric of the building. Sealing them with modern impermeable materials causes moisture to build up, leading to damp patches, peeling plaster, and even structural damage. If you’re seeing recurring damp, crumbling plaster, or efflorescence (white salt deposits) on your walls, there’s a good chance modern materials are the culprit. I’m happy to discuss what you’re seeing before you commit to any work.
