I instructed Trisy's for a party wall award on recommendation from a friend and have been delighted with their knowledge and service. They had do deal with a rather inconvenient schedule of condition for my neighbour and plenty of questions from said person, but they persisted and always kept me appraised and advised. I will be recommending Trisy's to anyone that needs a party wall surveyor. They are incredibly professional and knowledgeable. Thank you v much for your services thus far.
