Registered, insured and trusted across Dublin

Across Dublin 11

Your House Has History

Most Finglas houses share a build year and a floor plan. What they no longer share is a plumbing system, because seventy years of owners each changed something.

Cortech has worked across Dublin for over 5 years, RGI registered and fully insured. On a street like that we check what is actually there rather than what should be.

What Comes Up Most

Diagnose It Before Quoting

Six faults make up most of what we do in Finglas. What caused each one depends on what was changed in the house.

Leaks Stopped Same Visit

Found, stopped and the pipework repaired properly.

Heating Back On

Heating back on, with the real fault fixed

Gas Made Safe First

Gas made safe first, then repaired to standard.

Drains Running Again

Drains cleared and checked for the cause.

Taps and Bathrooms Sorted

Taps, showers and bathrooms fitted and repaired.

Catch It Next Service

Yearly service to catch wear before it fails.

Tell us what changed in the house and we will narrow it down.

Finglas House Types

Layout Points to Pipework

Terraced, semi-detached, village house or a newer build. Finglas holds all four, and the layout decides where we start looking.

Bathrooms moved. Many of these houses had the bathroom relocated or a second one added upstairs, and the waste run tells us when that happened.

Finglas West Terraces

1950s rehousing stock, often on original runs.

Finglas East Semis

Semi-detached houses with side access and gardens.

Old Village Properties

Older homes near St Canice's with their own layouts.

Newer Finglas Infill

Later builds with sealed pressurised systems.

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..... Thank you all the great excellent staff worker.... Pramila

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!

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.

FAQ

Frequently Asked Questions

How can I tell if the plumbing has been changed before?

Look for mismatched pipe. Copper meeting plastic, a boiler much newer than the radiators, or a cylinder with pipework running off in two directions all point to work done at different times. A photo of the hot press usually tells us a lot.
Yes. We cover all of Finglas, including Finglas West, Finglas East, Finglas South and the old village, along with the wider Dublin 11 area. Give us the address and we will confirm it on the call.
That usually means the two are on separate controls or a shared part has failed. On a cylinder system the hot water and the heating run off the same boiler but through different valves, so one can work while the other does not.
Yes, and it is a good time to look. On a house you have just bought nobody can tell you what was changed or when, so checking the boiler, the cylinder and the visible pipework is worth doing before anything goes wrong.
Yes. You get a fixed quote before any work starts, with no obligation to go ahead. We would rather spend ten minutes looking and give you a number you can rely on than guess over the phone.
Find your stopcock and turn the water off if anything is leaking. Note what changed just before the fault started, and take a photo of the boiler and the hot press. Those three things save time on the call.
