“Called at 9pm with water all over the kitchen floor. They picked up, gave me a flat price on the phone, and had it fixed before midnight. Fair and straightforward.”
Amelia R.
Islington, London
“Got three quotes for a water heater replacement. Thameside was the only one who didn't try to upsell me. Installed same day, cleaned up, and it's been running for a year.”
James T.
Camden, London
“Thought I had a simple clog — turned out to be a main line issue. They explained everything, showed me the camera footage, and fixed it for the price they quoted.”
