Some leaks announce themselves, a dripping joint, a wet patch under the sink. The expensive ones do not: a slow leak inside a wall, under a floor, or on a heating pipe that only shows up as a stain on a ceiling or a boiler that keeps losing pressure. The job is the same either way, find it before it spreads, fix it properly, and tell you honestly what caused it. LMB does that with a 207-review, 5.0 record behind the work.
Common leaks, and what they actually mean
Under-sink and tap leaks are usually a worn washer, a failed seal or a loose compression joint, quick once you know which. A toilet that fills constantly or a damp patch behind it points to the fill valve or the pan seal. A boiler that keeps dropping pressure means a leak somewhere on the sealed heating system, sometimes a visible joint, sometimes a buried pipe or a corroding radiator. A stained ceiling with no obvious source above it is the one to act on quickly, because by the time it shows, the leak has been running a while.
Because LMB is Gas Safe registered, a leak that turns out to be on the boiler or the central heating is not a job that needs a second trade. The same engineer traces the plumbing leak and the heating leak.
