“Hot water died on a Sunday with three kids in the house. Mainline answered, gave me a 60-minute ETA, and had a new unit in by lunch. Knew the price before they started.”

“Burst pipe under the slab at 11pm. They talked me through the mains shut-off on the phone, turned up fast, and the quote was the quote, no surprises on the invoice.”

“Booked them to install a gas cooktop. Proper licence, compliance certificate handed over on the day. The first plumber who actually explained what I was paying for.”
