How We Approach a Leak Repair in Cardiff
Water travels, so the place where you see a leak is not always where it starts. A stain on the kitchen ceiling might come from a shower tray, a bath waste or a pipe joint some distance away. We check the likely sources, find the actual cause, then repair or replace the faulty part.
Once the repair is done, we test it and check that everything is dry. If we find a part that is likely to fail soon, we will tell you, but we won't push work you don't need.
What To Do If You Have a Leak
Turn off the water at your stop tap if the leak is serious. It is usually under the kitchen sink. Turn off any electrics near the water, and catch drips with a bucket or towels. Then call us on 07535721488.
If you think the leak is on the water main outside your property, contact Dŵr Cymru Welsh Water. Find out more about our shower tray replacement service if your shower is the cause.

Leak Repair in Cardiff: FAQs
Where is my stop tap?
In most homes the stop tap is under the kitchen sink. In some houses it is in a utility room, downstairs toilet or under the stairs.
Can you find a hidden leak?
Yes. We check the likely sources, such as shower trays, wastes, pipe joints and valves, to trace where the water is coming from.
Why does my toilet keep running?
This is usually a worn fill valve or flush valve. We replace the faulty part so the cistern fills and stops correctly.

Yes. We repair leaks across Cardiff, including Roath, Cathays, Heath, Llanishen, Pentwyn and Whitchurch.
