  I have been delighted with the work that Cannon Clarke have carried out on my house. The initial survey and report were very thorough  and the remedial damp proofing work was carried out very professionally and carefully. I was kept informed at all stages and very impressed with their efficiency. Cannon Clarke is a great company to deal with and thoroughly deserves my 5-star rating.

  A beautiful job — our peeling mouldy cellar has been transformed, and draws admiration from every contractor we’ve engaged since.  They really know their stuff, and are sympathetic to the requirements of quirky listed buildings.
The team were super reliable, helpful and  efficient. Absolute go to if we ever need damp proofing again.

He talked us through the causes and solutions, as well as giving plenty of helpful prevention tips additional to the quote. If you’re experiencing any issues with damp in your property i would highly recommend.

  Davis-Lumsden is a new customer to Canon Clarke.  We transferred to them having worked with Jeremy Johnson their newly acquired General Manager for many years. Jeremy has always been a pleasure to work with, he is professional and has extensive knowledge within his field. His assistance in all of our  previous projects has been invaluable.  I have recently met and spoken with several of the existing Canon Clarke team and all again are professional and knowledgeable.  I am sure with Jeremy as lead at Canon Clarke he is only going to add value and experience to an already excellent team.
