From beginning to end, Pro-tech did an amazing job. We needed to replace a bad water heater and decided to replace the 65 year old boiler at the same time. It was a difficult job and other companies would have charged us an incredible amount of money to take the extra step of installation in an acceptable location for ventilation. Kevin and Scott did an fantastic job of installation and went the extra mile to make sure that the end result was esthetically pleasing. They clearly took pride in their work and cleaned up at the end of each work day. We highly recommend Pro-tech and appreciate the great job they did for us.
