Dr Rachel Rouse: “I would like to express my thanks to the installers for their hard work and professionalism” Abergavenny

Mr Philip Bear: “After having been previously let down by two other companies, we contacted Strandek and wanted the work done as quickly as possible. They stuck to the agreed start date and the work was carried out professionally and on schedule. They were helpful and efficient from the start and the final result was of a very high quality and finish. Their follow-up courtesy call was also much appreciated.” Cowbridge
