Frankly, it is rarely good to have to call a plumber, but if you have to, make sure it is Blue Diamond Plumbing.
I have had the need to engage the services of Blue Diamond plumbing on 6 or 7 occasions for different reasons each time (just what happens with an older house). Initially it was to clear our storm water drains and now I have them cleared by Rod and Ben every 6 months or so just to stay ahead of blocked drains and flooding. I have also had Rod help with an issue of dampness under our house by installing extra drainage and replacing taps. The last job was to clear the sewer drain and not only did Ben arrive within 30 minutes of my call, he was finished within an hour.
On each occasion Rod or Ben have turned up exactly when they said they would and do exactly what they said they would do, fixing the problems and completing their tasks quickly and efficiently. Oh, and they are both good blokes too!
I have absolutely no hesitation in recommending Rod's and Ben's work. They are prompt, efficient and get the job done.
