We were very happy to appoint Duchy Demolition as our contractor for asbestos removal and demolition of our newly purchased property in Cornwall. As we live 5 hours away it was important that we could trust Duchy to carry out the works in a professional and considerate manner. Both of these objectives were met and we were kept informed of progress throughout. We had no complaints from neighbouring properties and following completion our site was left clean and secure. Would highly recommend.

We often work with Duchy Demolition – in our experience they’re probably the most dynamic and professional demolition contractor in this part of the country.

Hi I’d just like to say a huge thank you to the driver of one of your trucks that was in Carbis Bay this morning just before 8am. The horse I was leading started to worry about a bag in the hedge behind him, your driver saw what was happening and pulled in and turned his engine off and let us pass him, then waited until we were well clear to start up again. This is awesome, so much better than the majority of drivers. Keep doing what you’re doing as this driver and all others from your company that I’ve come across whilst riding and leading horses in various parts of the county have stuck in my mind. Thank you again, your drivers kindness and patience was greatly appreciated.
