We’ve used Semtex for our plumbing needs and couldn’t be happier with the service.
Their response times are impressively quick. They always get the job done right the first
time and the team are friendly, approachable, and always willing to help or explain things
clearly. Highly recommend Semtex for reliable, high-quality plumbing service!
Dakota

Excellent service from Semtex, the two guys who installed our oven and hooked up the
gas for the hobs, left everything clean and tidy - they were really awesome. Quick,
efficient, excellent attention to every detail of the installation….. and, really friendly. Highly
recommend Semtex Plumbing
Alison

Really happy with the service. Communication was great, they turned up when they said
they would, and they found the problem, which the council fixed shortly afterwards. Also it
was cheaper than I expected.
Thanks Semtex
Ian

Easy to deal with. Job was done in a timely manner. Didn't go over quoted price and left
the site tidy.
Stephanie

Very efficient service. Worked out where my water leak was coming from immediately.
Wouldn’t hesitate to recommend. Appreciate the good work.
Caroline

Prompt, professional, kept me informed, courteous, worked with a smile, fair price. Highly
recommend.
Ed

Quickly turned up to unblock a drain in disgusting, filthy, cramped conditions and were
pleasant and cheerful while doing it! The cost was very reasonable for the time and effort
they put in. Very happy to recommend this company.
Mary

Best in town I think. Highly recommend!
Desmond

Came early, did a thorough trouble shoot of the issue, listened as symptoms were
explained, and solved the problem. Very professional in all respects. Would/will use again.
Rick

Very pleased with the job, as 3 other plumbers said they couldn’t find where the leak was
coming from. Looking forward to your help with the next big job.
