Really helpful, knowledgeable staff who seemed really happy to help with advice. Just what I needed . Thank you. All the materials seemed reasonably priced and they had all the tools I needed too so didn't have to go to multiple places.

They have stopped selling St Astier lime paint which i have had before from them. However they were able to come up with a pretty good colour match from a different manufacturer.

Visited Cornish Lime this past weekend to purchase some lime mortar for a scratch pointing job on an old fire party wall in my loft. Explained to the lads what I was doing with no knowledge or experience. They could not be more helpful, providing me with a product fit for a scratch job that undoubtably saved me money and plenty of easy understandable advice. I will definitely be using and recommending Cornish Lime again. Thanks lads

Just spent the most brilliant day on the lime plastering and rendering course. So informative and great facilities..outstanding craftsmen sharing their wealth of knowledge. Can't wait to get stuck in to our Little cornish cob and granite cottage renovations..I'm feeling much more confident in making the right choices for our home.

My wife and I bought an 1800's Cornish cottage last year and have found ourselves in a position where we need to renovate. After having a consultancy carried out with another Cornish consultant and a recommendation from a colleague of mine, I got in contact with Cornish Lime for advice on products that would work well with our granite property.

Adam and several other colleagues have been very helpful so far with advice on construction, materials, and even loading my car. I've bought a few of their products, including insulated celenit board and walling mortar, which seem to be great quality.

Very very helpful nice people. They seem to stock everything and all the builders merchants in Penzance recommend them and get their supplies from them. I am a DIY amateur and have never used lime plaster, but with their help, plus their supplies and tools and about 3 telephone calls to them (and YouTube) I have managed to lime plaster a rough granite wall with an acceptable (I think) smooth result suitable for painting in a while.
