RGI Plumber in Dublin 22

Dublin 22 holds a twelve-hundred-year-old village core and the 1970s estates built around it. We work on both every week.

Registered, insured and trusted across Dublin

Clondalkin to Neilstown

Built for Dublin 22 Homes

Clondalkin village still has its nineteenth-century mill cottages and a library from 1911. A few minutes out, the estates at Neilstown and Bawnogue are barely fifty years old. Same postcode, two completely different jobs.

Cortech works both ends of it. RGI registered, fully insured and over 5 years in Dublin, we look at what is actually in the house before quoting, so the price holds whatever the age.

Homes Across Dublin 22

Match the Fix to It

Knowing the build tells us where to look. Dublin 22 holds four broad types, and the pipework, heating and access differ across them.

Extensions are the other common thread. Plenty of these homes gained a kitchen, bathroom or attic room since the 1990s, and the join to the original runs is where faults show.

Clondalkin Village Homes

Older cottages and houses with their own layouts.

Neilstown and Bawnogue Estates

1970s semis still on much of their original pipework.

Moorfield and Cappaghmore Houses

Later estate builds reaching boiler replacement age.

Quarryvale and Liffey Valley

Newer homes with sealed systems and correct parts.

They responded quickly...very professional and reassuring...they identified and dealt with the problem efficiently.

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

Do you cover all of Dublin 22?

Yes. We cover the whole of Dublin 22, including Clondalkin village, Neilstown, Bawnogue, Monastery, Dunawley, Cappaghmore, Moorfield, Fonthill, Quarryvale and out as far as Liffey Valley. Give us the address and we will confirm it on the call.
Low pressure upstairs usually points to a gravity-fed system. Older Dublin 22 houses feed the upstairs taps from an attic tank, so the pressure depends on how far the water drops. A pump or a move to mains-fed pipework fixes it.
Yes, someone needs to be there to let us in and sign off the work. If you are a landlord and your tenant is at the property, we can deal directly with them once you confirm that by text or email.
Yes. Plenty of the 1970s houses around Clondalkin were built with a back boiler behind the fireplace. Swapping one means a new boiler, new controls and usually new pipework at the fireplace, so we look at the room before quoting.
Most cylinder swaps take a working day. Draining the old one, fitting the new cylinder and refilling the system is the bulk of it. Older Dublin 22 houses sometimes need pipework altered to suit the new size, which adds a few hours.
Yes. We service boilers that have gone years without a check. Expect it to take longer than a routine service, and expect a few worn parts. If it is past economic repair we will say so rather than keep charging you.
