Leak detection and regassing in St Albans
If a system in St Albans has needed gas before, the original leak was probably never fixed. Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat.
Flare joints are a frequent leak point on older split systems, so they are among the first things checked on a visit in St Albans. We cover St Albans as part of Hertfordshire, roughly 7 miles from Watford. Homes in AL1 and AL3 are all within our coverage.
