Simon Pratley
Verified CustomerI just had a repair done by Kaleb and Vas and I was very impressed. We woke up with no hot water this morning and called Curl Curl Plumbing for help. The boys came out the same day and fixed the issue. They kept me informed with every step of the process and I'm very relieved to say, everything is fixed and will be having hot showers again, which is a relief!
