The technician, Aaron, called me to let me know he was on his way even before the 2 hour window. He laid down a padded blanket to protect my hardwood floors. He promptly found what was wrong with my fireplace and fixed it at a reasonable price. The repair was quick and he left my condo completely clean. Not only did he clean the glass as well as the fireplace I didn't need to know the type of fireplace, which was convenient as it is in a rental property. I would have no hesitation recommending this company if you have a fireplace issue.
