    "Demarco's installed a new central heating boiler. I found them pleasant quick and efficient. I particularly appreciated that Mr Demarco always replied straight away to all calls and text messages . I was never left waiting to hear back, which was very reassuring to me as an older customer."

    "Excellent service. Lee sorted out a long-standing problem with a leaking connection at the rising main in a most professional manner. Not the cheapest, but fair value. Would certainly use again."

    "I was very pleased with the overall experience with Demarco Services, Shane responded in good time to my initial enquiry, he reassured me the problem could be resolved and set my expectations of an ETA by an engineer. The Engineer Lee attended when scheduled, my wife felt comfortable with him and we are both happy with the quality of work. I thought the cost reasonable for the work requested and they attended very quickly from our first contact."
