What our Customers say
Trusted by homeowners and businesses across Northern Ireland for reliable, professional plumbing work that solves problems right the first time.
Your No.1 choice for a plumber on the North Coast I simply can't recommend Mathieson Plumbing enough. Quality of work was second to none. Hayley went out of her way to find a tile to blend in with the existing decor, showing a level of care and pride in her work that is increasingly rare. She was equally happy installing the shower I'd sourced myself. Given the amount of time Hayley had to spend, I felt the price was more than reasonable. All round great service!

Fantastic service Hayley was extremely helpful in fixing a couple of plumbing issues I had. Everything was fixed quickly and the cost was really reasonable. I'd be very happy to recommend Mathieson Heating & Plumbing for personal or business!!.

5 stars 🌟 Hayley is worth the 5 stars & more. She’s is a very competent tradesperson! Highly recommend her as a plumber & no qualms about a Saturday bathroom refurb.

First class service What a pleasure to get such a reliable person , who's work and knowledge was first class. Hayley arranged a time to suit us and updated us on her time of arrival, she serviced our gas boiler and sorted out a small leak that had just developed, I would thoroughly recommend her to anyone who needs a plumber / gas engineer.
