"Keystone are an excellent company to work with. Their staff and site team are very helpful and well organised. They always achieve a high quality finish. We would definitely work with them again!"
Ian McArdle - Architect, IMA
" The client, Derwent London, could not have been more delighted with Keystone’s work on the Oliver’s Yard project, and that work has informed much of their later thinking when it comes to stone and stone cladding. We were very pleased with the outcome at Oliver’s Yard not only in terms of the final product but in the way Keystone embraced collaborative working and their positive attitude to sourcing and installing the product. We have worked with Keystone on several projects since Oliver’s Yard and would happily recommend them to other specifiers/architects and client teams. "
Lhairg Foreman - Grangewood
" Keystone are a very important member of our supply chain. Their work is always of a very high standard, and they have the kind of flexible and accommodating approach on site that we, and our clients, depend on. I look forward to working with them again. "
Robbert Williams - Chartered Surveyor, Church Meadow Homes
" My experience in dealing with Keystone has always been very positive. They offer their expertise at the initial design and material selection phase, and have always undertaken the work on time, within budget and to a high standard. And when modifications are required they are always accommodating and fair. They have a very helpful and straightforward approach, combined with a high level of professionalism. In short I have no hesitation whatsoever in recommending them. "
