We’ve recently topped up our attic insulation. The service level that GNI provided us was nothing but exceptional. Starting with Matt providing the recommendation and estimates, to Nick and Sarah’s prompt reply to all my questions. On the day of the insulation, Connor, John and Will carried themselves with professionalism, friendliness and efficiency These three gentlemen even took the time to inform us what to look out for in the attic and how we can maintain it. One rarely finds such a level of service and competency these days, and GNI reminded us what a high standard service level is about. We will look no further than GNI for our next insulation needs. Thank you GNI!
