New Radiators
Customer Service
Our 4th time using Stelfox Plumbing & Heating, this time to replace all the radiators in the house. As expected, we were extremely pleased with the final result. Ciaran paid great attention to ensure the radiator placement was perfect and that the pipework was symmetrical. Certain radiators were trickier to replace than others, but despite the extra work, Ciaran was very fair with the pricing. Would highly recommend and will definitely use again in the future.

New Shower Replacement
Customer Service
Ciaran recently replaced a seized shower unit built into the wall. He did so with great care and managed to match the new tiles with much older tiles. Ciaran is very professional and his service is efficient. We have used Ciaran numerous times for drainage issues and repiping and cistern replacement and the service has been fantastic! Highly recommended for any plumbing works!

All the internals fixed in broken toilet
Customer Service
We would definitely recommend Kieran at Stelfox, he did everything he said he would, when he said he would it. He viewed the job on the Friday was back after the bank holiday Monday to fix it. The work was carried out in a highly professional manner, he was on time, clean and tidy and got it fixed for the price agreed. What more do you want. ๐Ÿ‘๐Ÿป๐Ÿ˜€

New gas pipe fitted for a new gas hob
Customer Service
I needed a gas supply to a new hob which is being fitted shortly. I telephoned Ciaran (Stelfox Plumbing and Heating) and left a message for him asking him to call me back which he did promptly. We arranged a date and time for the job. On the morning of my job, there were traffic problems which delayed Ciaran slightly but he texted me to let me know he was stuck in traffic and that he was on the way. I really appreciated this because then I knew he was on his way. No other tradesmen I have engaged in the past has done this and often I have been left waiting and wondering if they were still going to arrive. Ciaran installed the new gas pipe for the new gas hob. The job was neat and fitted against the wall perfectly even taking into consideration the wall was wonky as it is a period property. Ciaran worked quietly and cleaned up and hoovered after he had finished. I have engaged many plumbers and heating engineers over the years and I can honestly say that Ciaran is the best. He is polite and listens to you and is very professional in every aspect. He is very respectful to the property and has always done a fantastic job for me every time I have needed work done. I thoroughly recommend Stelfox Plumbing and Heating.

Fixing two radiators that stopped working plus annual boiler and cylinder service
Customer Service
We telephoned Ciaran and asked him if he could look at two radiators that had stopped working. He arrived promptly on the agreed day and identified the problems very quickly. He fixed one radiator straight away and is returning to fix the other one. Whilst he was on site, Ciaran carried out our annual boiler and megaflo cylinder service and completed the necessary paperwork. Ciaran has carried out extensive heating and plumbing work to our property and we would not consider engaging anyone else because he is punctual, a very good communicator, tidy, clean and very polite and moreover he is an excellent heating engineer and plumber. He is very diligent and listens to any concerns or ideas you may have. We would not hesitate to recommend Ciaran for any heating or plumbing work you may need.

Redoing Kitchen Pipework/Dishwasher Installation
Customer Service
This is our second time using Ciaran. Like last time, the quality of work was impeccable. We required the piping in the kitchen to be redone as it was extremely old and rusted, as well as requiring additional outlets for a dishwasher. All work was carried out in a timely and efficient manner, with great attention to detail. If things like symmetry and perfect lines bother you, I highly recommend Ciaran, he makes extra effort to ensure it is not just functional but looks good too. We will always use him for any future plumbing/heating jobs.

Very responsive. Fixed the problem first time.
Customer Service
Ciaran was quick to respond to initial contact. He helped identify the problem on WhatsApp and as a result I was able to order the replacement cartridge for the shower mixer. As a result he only needed an hour or so on the day to fix the problem. Saving multiple visits. Tidy, Friendly and on time. Would definitely recommend.

The analysis of an award leakage was quickly done
Customer Service
Ciaran was clearly a very professional plumber from the outset, as well as also being cool, calm, and collected, and rapidly brought the offending leakage problem under control, as well as leaving the site clean and tidy. I would recommend Ciaran to others, and I will certainly contact him if there are any future plumbing or heating issues needing attention.
