Clarion restored an indoor mosaic pool that had turned cloudy after a faulty dosing pump. Alistair attended personally, corrected the saturation index over two sessions, and rebuilt the dosing lines without fuss.
Charles M., Cobham, GBThe contrast with our previous contractor is pronounced. The technician arrives at 08:30 promptly, carries his own auxiliary vacuum equipment, and leaves a printed record of water chemistry on the counter.
Fiona H., Sevenoaks, GBSolid, dependable maintenance. They noticed our heat exchanger pressure was dropping before it caused damage to the burner assembly. Payment via electronic bank transfer is handled smoothly once the job is finished.
