An urgent plumbing problem is exactly when people get overcharged, because they are stressed and the clock is running. LMB does the opposite: you are told what the visit will cost before Lloyd sets off, so you decide with the number in front of you. The public record, 207 Google reviews at a straight 5.0, is the reassurance that the honesty holds even under pressure.

What counts as urgent, and what to do first

A burst pipe, a fast leak, no heating or hot water in cold weather, a boiler that has locked out, an overflowing toilet, these are the calls where speed matters. The first move for a burst or fast leak is to turn off the stop tap, then call 07712 646488. If you can smell gas, call the National Gas Emergency line on 0800 111 999 first.

LMB offers same-day call-outs where the diary allows and daytime emergency help, not a 24/7 line, and that is stated plainly rather than promised and missed. Coverage runs across Cardiff and the Vale from a Pencoed base. As a Gas Safe registered business, an urgent plumbing problem that turns out to be the boiler is one trade, not two.

Questions people ask

Can you come out today in Cardiff?

Where the diary allows, yes, same-day for an urgent problem. LMB offers daytime emergency call-outs rather than a 24/7 line, stated honestly. Call 07712 646488 to check the day.

What do I do about a burst pipe right now?

Turn off the stop tap to stop the flow, then call 07712 646488. Turning off the water first limits the damage while help is on the way.

What will an urgent visit cost?

You are told on the phone what the visit will cost before Lloyd sets off, so there are no hidden call-out fees added afterwards.

My boiler has died, can you help urgently?

Yes. As a Gas Safe registered business, urgent boiler problems are covered alongside plumbing. Honest diagnosis first, and a fixed replacement price if it is beyond repair.
