Hallas & Co were the surveyors appointed to oversee the external redecoration project for our building. As one of the directors, I worked closely with Hallas, specifically Andy Hentschel, on the project. I found Andy to always be extremely knowledgeable and professional in all my dealings. He also consistently went over and above in providing expert guidance on a number of challenges encountered during the project. I would happily work with Hallas / Andy in the future.

I instructed Hallas and Co. Ltd to carry out a defect report on my roof, which had been leaking for months and I had many roofing companies to try find the cause. Hallas and Co Ltd inspected the roof and found the problem. I am very happy with the service and the informative report I received, I would highly recommend them.

Perhaps mine is an isolated case that slipped through the cracks but I was not impressed by the service I had (or lack of it). I contacted Hallas & Co very early on Tuesday morning regarding an ongoing problem with water ingress into a block of flats. This was getting quite urgent. I had a prompt reply and was told that my correspondence was passed to the surveyor and I would be contacted shortly. I also wrote to another firm who responded immediately with the required information. I decided to wait for Hallas to respond as they were my first choice but when nothing happened by late Friday afternoon, I decided to instruct the second firm. I can understand that people can be busy but what would it have taken to just let me know that there is a delay and that they will contact me after the weekend? That is called customer service. I just felt undervalued and disappointed as a potential customer. Wrote to Hallas that I decided on the second firm due to the lack of communication, saw that my email was opened, but have not even had the courtesy of a reply.
