If there is a more talented, thoughtful, interested Heritage builder than Jamie Bransden of Keystone, I would be amazed. If you are fortunate enough to engage Jamie you will be thrilled with the results and become friends for life. I have read the reviews posted reference Jamie (Keystone) and I can honestly say I could have written all of them. Outstanding! He actually cares...

Jamie is a very conscientious worker. He takes great care to ensure a quality job is provided. I am delighted and so much happier now that the front of my cottage has been renovated and restored to the correct lime-wash and she can now breath properly again. I am also happier knowing I have an improved drainage system and the repointing is perfect too. All his work looks fabulous. Jamie’s enthusiasm for doing quality work using the old methods appropriate for my cottage comes out in his work. Jamie is a very reliable, friendly, trustworthy and professional builder. I would not hesitate in enlisting him again if needed.

Jamie’s first job for us was in 2012, which involved completely renovating/restoring our stone 2 storey coach house & roof in South West Wales. We were so pleased & impressed with the quality of his work that we invited him back subsequently to restore the stone workshop, middle barn & house roof & exterior, these projects ran from 2013 to 2014. Jamie is an extremely conscientious & versatile worker, thinking through all aspects of his work, taking great care & ensuring a quality job is provided. Jamie is a very reliable, professional & friendly builder; we would certainly not hesitate in appointing him again if needed.

We can thoroughly recommend Jamie and Toby as skilled, dedicated, trustworthy workers, and all-round lovely people! Keystone restored our damp, slightly shaky old Victorian house back into a beautiful stone building, with replacement lintels, expertly rebuilt and repaired brick arches and chimneys, and beautifully repointed with lime mortar. Internally, they removed crumbling original plasterwork and replaced it with carefully applied horsehair and lime plaster, which has now completely blended in with the surrounding remaining original plaster. Thoroughly professional attitude , considerate and good communications...they even fed the cat for us when we were away! Highly recommended! Thank you from Sarah and Justin.

Jamie has has been a fantastic builder on our recent barn conversion. He is well organised, quick, and does a really good job. He does things properly is good to communicate with and has a great deal of experience in old buildings, lime plaster and roofing. He really is a great find and I wouldn’t hesitate to have him back for our next project and would be willing to wait until he is available.
