David from Prima Plumbing did an excellent job! He was professional, reliable, and went above and beyond to make sure everything was done properly. Even though it was already dark, he stayed and got the job done.

David came back to check up and follow up afterwards to make sure everything was working well and that I was happy with the service. That level of care is hard to find.

Highly recommend David and Prima Plumbing 👍

I had an emergency plumbing issue when my shower drain became completely blocked and started overflowing. From the moment I called, the booking process was smooth, professional and incredibly helpful.

David attended the property and was absolutely fantastic. I was quite stressed about the situation, but he was incredibly reassuring, took the time to explain everything clearly, and genuinely helped calm me down. He was understanding of my circumstances and worked with me to find a solution that was fair and affordable.

Absolute professional – highly recommend David from Prima Plumbing

I recently had David from Prima Plumbing out for a job, and I couldn’t be happier with the experience. From start to finish, his service was excellent.

The work was done quickly without any shortcuts, and his communication was clear throughout, so I always knew what was happening and why.

Had an emergency over the weekend with a burst hose underneath our bathroom tap. Water was gushing everywhere!
Called David and he was able to attend as soon as possible.

From the moment he arrived, David’s professionalism, reassurance and friendly approach not only made my family feel at ease, but also gave my mum real confidence and peace of mind in her own home. He quickly identified the problem, fixed it efficiently, and explained in simple terms what had happened and how to avoid it in the future.

What stood out most was how thorough he was, checking everything carefully to make sure there were no other hidden issues. He treated our home with respect, left the space clean and tidy, and even followed up afterwards to ensure everything was still running smoothly.

It’s rare to find a tradesperson who is this reliable, trustworthy and genuinely caring. I wouldn’t hesitate to recommend David to anyone looking for a skilled plumber who goes above and beyond.
