“Danny and his crew did a really great job.”
We asked for quotes for a new boiler. Danny's quote was the most detailed and he gave a price for a range of boilers. We went for the Veismann. We needed a lot of small extra jobs done as well and he gave priced for those up front. He responded very quickly to all queries, this is unusual nowadays when people are so busy. He came when he said he would and he and his crew were super effiecient, pleasant and tidy. He sorted out some problems we had with the plumbing and the price was fair and transparent. I am really impressed with the quality of the work they did. If I need any plumbing done in the future I will choose Castleknock Gas without hesitation.

“Replacement Boiler”
Dan was exceptional from start to finish. Arrived on time, did a clean quality job and then priced some more work for me. I highly recommend him.
“Excellent.”
The whole experience, from first contact with Dan, until new Viesman boiler was fitted, couldn't have been better. Professional, courteous and clean! Highly recommend 👍

Very professional crew. No damage whatsoever to any of the surrounding furniture/fittings.Job complete in one day. System needs a slight tweak to complete project.

What makes your services standout?
Our installations speak for them themselves. Our team of qualified engineers take great pride in there work and it shows in every single boiler install
What is your top advice for your customers?
It’s expensive to hire a good, well recommended engineer, but it’s even more expensive to hire a bad one. Lifetime expectancy of a gas boiler is 15 years. Do it correctly. Once!!
