“Hot water system failed on a Friday. Contacted Cal from Horncastle Plumbing on the Saturday and requested a service call on the Monday. Cal arrived ontime at 8am, provided alternative quotes to fix the problem. Quote was accepted and I had a new hot water heater installed by 1pm. One couldn’t ask for better service. Highly recommended for a local plumber.”
