A bloke in Grangetown rang us last winter. Said he could smell something near the meter cupboard under the stairs but was not sure if he was being paranoid. He was not paranoid. There was a slow leak at a joint that had been working itself loose for months.
That is the thing about gas emergencies. Sometimes they announce themselves loudly. Other times they are quiet and you just get a feeling that something is off. Both of those feelings deserve a phone call.
When we come out on an emergency we are not guessing. We are checking. We find the source, make the area safe, and tell you plainly what is going on and what needs to happen next. We have done late callouts across Cardiff, Llandaff, Pontprennau, all over. We do our best to get to you quickly because we know waiting around when you are worried about gas is no fun at all.
If you are not sure whether what you are dealing with counts as an emergency, just call. The worst that happens is we tell you it is fine and you feel relieved. That is a good outcome.
