We had recently had our walls insulated with Insulmax®. We noticed the difference straight away, with the house holding its warmth longer and taking less time to heat. We were also very impressed with the prompt communication and honest quote. Eamonn and his team really went the extra mile ensuring we had the install done at times that suited us, as our baby arrived right around the install date. Other tradesmen could learn a thing or two about great customer service from these guys! Highly recommended.
