Dublin 8 is dense, old and heavily rented. We work on it every week, from emergency leaks to landlord gas safety checks, with a fixed price first.
No obligation. Fixed quote before any work starts.






Plenty of Dublin 8 lives below street level. The classic house here has rooms under the hall floor, and that is where leaks collect, drains back up and damp shows long before anyone finds the cause.
Cortech covers Dublin 8 around the clock, RGI registered and fully insured, with a five-star rating on Google. Tenants, owners and landlords get the same team and the same fixed price.
Six jobs account for most of our Dublin 8 call-outs. Tell us which one sounds like yours and we will tell you how urgent it really is.
We find it, stop it and repair the pipework.
Combi, system and oil boiler faults diagnosed and fixed.
RGI-registered leak detection, then the repair.
Blockages cleared and the cause checked properly.
Drips, pressure problems and full bathroom plumbing.
Annex E checks and the certificate you must hold.

Four property types cover most of Dublin 8. Each has its own weak points, and we work on all four every week across the Liberties, Kilmainham and Inchicore.
Access decides a lot here. Narrow streets, shared halls and rooms below ground mean getting to the pipe takes longer than the repair, so we price the whole job rather than the last ten minutes.
Rooms below street level with drainage that needs watching.
Split houses where one fault reaches several tenants.
Small 1840s homes still on their original pipe runs.
Pressurised systems needing the correct parts and pressure.
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.. They were reliable and friendly...They also make sure that everything was sorted accordingly in a proper way. I would highly recommend Cortech Plumbing & Heating to anyone looking for a trustworthy and professional staff worker... I extremely appreciated their excellent service from start to finish.....

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
