"We just moved into a very old home with two very large, equally old fireplaces. We needed to find someone we could trust with this historic stone house, who would do the job right, on time, and for a fair price, all while respecting the original craftsmanship. Expert Chimney &Roofing exceeded our expectations. They were so easy to work with, gave us a wonderful price, and got this immense job done in less than 2 days. All of the workers were kind, respectful, and understanding, they cleaned up after themselves and taught me how to take care of my fireplaces. I would highly recommend them to anyone - old home or new!"

"Denis and his team came in evaluated the leak and worked to find the root cause of the issue. He quickly fixed the damage and advised on different courses of action to take to fix the roof. In the end they fixed the damage from the leak and replaced the back part of my roof. Their estimates were quick and accurate he, they provided pictures through the process and quickly completed both jobs. I would recommend them and use them for future projects."
