Al is amazing. I called on Friday night after 5pm; he promptly referred his network who might be able to help me out because he was tied up with other works. He came out to help me out on a Sunday and identified the gas leak that was red tagged by Enbridge. It surely saved me some money without purchasing a new stove. If you are looking for someone to fix or to install gas lines, I'm 100% guarantee you won't be disappointed with Al's friendly and genuine service. Thanks, a homeowner in Markham!
