Customer reviews


There was a crack in my shower tray, I asked for a quote to get it replaced and they replied the same day and attended whenever was good for me. 


Slawomir was polite, respectful of my home, he explained the problems, and options. He worked clean and efficiently in replacing new toilet flush. I am happy to use him again


Slawek has completed two plumbing jobs for us over the time. The most recent one yesterday- radiator removal and installation. He is very professional, accommodating and efficient. Gets our highest recommendation.

Came within 24hrs, on-time and very efficient. Only a small job but slight problem with fixings – overcame them with no fuss or bother. Will definitely use again and happy to recommend.

WATCH: How we pinpoint leaks

Most specialist leak detection companies use similar methods. There isn’t one method that’s used to locate any type of leak. Normally, several techniques are used on each job. Results from each technique allows attention to be focused in a specific area.

We’ve produced a series of videos to show examples of how the water leak detection techniques are used in different situations.

This video shows some of the techniques used when the source of damp could be either plumbing pipes or the roof.
