Had an emergency situation and not only did Norm’s respond exceptionally fast (even on a Sunday) but they did the job quickly and well and went the extra mile to ensure all was as it should be. I have used them often in the past and due to the quality of both the work and the customer service, I will most certainly use them again and also recommend them to family and friends!
