Get a Sandymount Plumber Fast

Sandymount sits right on the bay, and that changes the plumbing. Salt air, low ground and old red brick all wear differently here.

Registered, insured and trusted across Dublin

Beside Dublin Bay

Know What Salt Does

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.

What Wears Out First

Stop Small Leaks Spreading

Six faults make up most of what we do in Sandymount. Salt and old pipework are behind more of them than people expect.

Leaks Stopped Same Visit

Traced in old pipework before the damp spreads further.

Heating Back On

Boiler, pump and control faults diagnosed and fixed.

Gas Made Safe First

RGI-registered gas leak detection, made safe, then repaired.

Drains Running Again

Blockages cleared and the surface water drain checked.

Taps and Bathrooms Sorted

Corroded outside taps, weak showers and full bathrooms.

Checked Every Year

Annual boiler service with flue and CO checks.

Not sure which one? Send a photo and the address and we will work it out.

Homes in Sandymount

Spot Where Water Gets In

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.

Sandymount Green Red Bricks

Victorian terraces on much of their original pipework.

Strand Road Period Houses

Coastal frontage where salt reaches external pipe runs.

Mid-Century Sandymount Semis

Later houses with gravity systems reaching the end.

Newer Sandymount Apartments

Sealed pressurised systems serviced with the correct parts.

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

Does being near the sea damage pipework?

Yes. Salt in the air speeds up corrosion on exposed metal, so outside taps, external pipe runs, brackets and boiler flue terminals wear faster near the strand than inland. Indoor pipework is unaffected, which is why faults here tend to start outside.
Yes, where the system suits one. A shower pump works on a gravity-fed system fed from an attic tank, and it lifts the flow at the shower. On a mains-pressure or combi system a pump is the wrong fix, so we check first.
Yes. Anything inside your own apartment is normally yours to arrange. Work on shared pipework, risers or the building fabric usually needs the management company’s approval first, and we will tell you which side of that line a job falls on.
No. One service a year is the standard either way, and that is what keeps most manufacturer warranties valid. What changes near the coast is where the engineer looks, because the flue terminal and any external pipework take the most wear.
Clear anything blocking the gullies and drain covers outside first, because leaves and sand block them quickly here. If water is still rising, call us. A drain that backs up only in heavy rain usually points to a partial blockage further down.
Yes. We are open 24 hours, so weekends and evenings are covered the same as weekdays. Call with the address and what is happening, and we will tell you when we can be there and what it will cost before we set off.
