Every aspect of dealing with Mark was excellent.
He responded to my ad in plenty of detail and gave an idea of what the work may cost (which was dependent on a number of factors).
Mark called me to arrange a time to visit and was very thorough in obtaining information before a day & time was agreed.
During his visit, Mark was again very thorough and informative in trying to find the gas leak. Unfortunately he wasn't able to find the leak, which was clearly frustrating for Mark, but he did everything he could to help us with our issue (even down to written instructions on how to find the right tradesperson to help!)
Thanks again Mark, your help was invaluable!
