Sandymount sits right on the bay, and that changes the plumbing. Salt air, low ground and old red brick all wear differently here.
No obligation. Fixed quote before any work starts.






Sandymount Green stands where an eighteenth-century village called Brickfield Town once was, named after the brickfields that supplied it. Those red brick houses are still here, and so is their original pipework.
Cortech is RGI registered, fully insured and over 5 years in Dublin. We look at what the sea and the years have done to the pipework before putting a price on it.
Six faults make up most of what we do in Sandymount. Salt and old pipework are behind more of them than people expect.
Traced in old pipework before the damp spreads further.
Boiler, pump and control faults diagnosed and fixed.
RGI-registered gas leak detection, made safe, then repaired.
Blockages cleared and the surface water drain checked.
Corroded outside taps, weak showers and full bathrooms.
Annual boiler service with flue and CO checks.

Sandymount homes fall into four types, from Victorian red brick to recent apartments. We work on all four every week.
External pipework is where the difference shows. Outside taps, exposed runs and boiler flues sit in salt air here, and they give out years earlier than the same fittings inland.
Victorian terraces on much of their original pipework.
Coastal frontage where salt reaches external pipe runs.
Later houses with gravity systems reaching the end.
Sealed pressurised systems serviced with the correct parts.
Everything on this page is done in-house by RGI-registered plumbers. Tap any service to see the detail, or call and we will tell you what the job needs.

Monday 14th September 2026. I am extremely happy with the service I received from Cortech Plumbing & Heating. My boiler was leaking and there was a strong smell of gas,which was very concerning and worrying as well. They responded quickly...very professional and reassuring...they identified and dealt with the problem efficiently. Honestly I really appreciated their prompt response... knowledgeable and excellent customer service..

Massive thank you to Ben from Cortech who came for an emergency call out to find my wedding ring. 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!Posted on 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.Verified by TrustindexTrustindex verified that these reviews were published on Cortech Plumbing's Google Business Profile. Learn more
