It’s 2nd time I’ve used the Rosetta Group. First time was Woody - excellent service, knowledge and couldn’t fault him, quite the character remembering him from a few years back. Last week Adam arrived on time and fixed my hot water issues quickly and efficiently. Yes, perhaps a little more expensive than others but the workmanship, service and peace of mind is totally worth it. Happy to recommend and happy to use again. Regarding obtaining credit card numbers prior to any work - I don’t have any issues with that - do provide them every time I check into a hotel and it’s good management and business practice to avoid bad debtors which we, as paying clients, have to carry.

***Highly recommended**** I contacted Rosetta Plumbing for installation of new hot water system. It was very professional right from the beginning - - The customer service representative who attended the call - 'Adam' whose impeccable craftsmanship was beyond expectations - and finally 'Woody' whose special appearance has made my day. By the end of it, I got a new hot water system professionally installed, a decade of piece of mind and two mates whom I'd like to bother for all my future plumbing requirements. Thanks guys
