Below are quotes from letters we have received from our customers following work we have carried out.


As a long-term client I have found both your installation and maintenance services excellent. In my opinion you provide a prompt, efficient, clean and friendly service and I wouldn’t hesitate in recommending your company to friends and family.

– From Brendan in Greystones

Boiler cleaning, check on heating system, water tank. Installation of 2 radiators and water tank and four taps. The work was done efficiently with courteously and cleanliness. We were very satisfied with the two workers that came to our house.

– From Brendan Smith in Stillorgan

We are very happy to recommend John McGrath Plumbing. They completely overhauled our heating system in a most accommodating and professional manner. We have been delighted with the outcome and their quotes were competitive.

Hi John. I just wanted to say thank you both for a very professional and tidy job. You took the time to explained the clocks and controls to billy and for the first time since another plumber installed the system we realize what they are for. Many thanks and if you have a website you can quote me.

– Joan and Vinny

Our new boiler seems to be working well and delivering warmth seemingly far more efficiently than the old boiler did – ever! So thank you once again for the care and skill which seems to be the hallmark of your work here. I would have no hesitation in repeating this unsolicited endorsement for publication should you need me to.From Adam and Vicky in Greystones


Just wanted to say, Thanks so much for both jobs you did at my house. Initially I called to get boiler serviced and while you were in the house you checked so much stuff.  Friendly and professional service. Im Impressed ! Paul, Greystones.
