Plumbing in Glasnevin

We Know Glasnevin’s Older Homes

Many Glasnevin homes are older redbricks near the Botanic Gardens. They look great, but the pipes and heating inside are often decades old. That means weak shower pressure, a boiler that struggles in winter, or a slow leak under the floor. That is where we come in. Cortech is an RGI-registered team that knows Glasnevin’s older houses, from re-piping and boiler upgrades to emergency leaks, and we agree a clear price before we start.

Didn’t need any plumbing work thankfully as he found it in about 10 seconds by figuring out what had happened - a very logical approach. Left me feeling silly, but very grateful. Thanks so much!

 Trustindex verifies that the original source of the review is Google. I had a shower unit locked open with water flowing for a couple of hours and needed a call out. Found Cortech on Google and rang them about 9.30 am on a Friday morning. The service man, a really helpful guy called Ben was here in 40 mins and sorted the problem immediately. He also helped me find a company who had a replacement unit and parts.

From my initial call, to job completed ( including help with finding replacement unit ) took 45 mins. The speed and efficiency of the service, plus the really pleasant manner in which I was dealt with was a breath of fresh air. I would highly recommend Cortech Plumbing.
