‘Huge thanks to you all for a brilliant service from start to finish. The wall looks better than it has for the last year, even without the re-decorating, yet!

As always, your Surveyor is a gem and totally reassuring when explaining the necessary works and treatments.  The operative was a pleasure to have carry out the works and was even polite enough to drink a my tea! Please pass my thanks to them both. Again!’

‘Fantastic service. We booked another damp surveyor who visited and gave very big but vague estimates about the work. To get a second opinion, we went to preservation treatments, the service could not have been better. They gave an honest recommendation about the work needed (or not). Great, honest service.’
