Called GasGuys after we noticed a supply line gas leak in our basement and Enbridge shut our gas off - George was upfront with the estimated cost based on description and photos of the site and he was able to come to the house within about 3 hours of our initial call.
He was extremely courteous and walked me through the process of the repair and testing of the gas line to find out if any other leaks existed. He ended up finding 3-4 additional leaks (including providing video of the bubbling during testing) which were repaired, cleaned up a number of other old connectors that were no longer to code and shortened and capped an old gas line that was no longer in use.
In all, I probably could have found a cheaper company to do this repair but I don't want to mess with half-measure repairs to gas lines. The confidence George provided in the thoroughness of his repairs was absolutely worth it and I wouldn't hesitate to recommend them.
