Nick and Martin weren't only punctual, they were early, which worked out great for us. They got right to work, letting us know how they would perform the job, and what materials they would use. The total job took about 3 hours, a bit longer than anticipated as we asked them if they could install an additional line for the gas range, which they willingly did. They also gave advice about how to maintain the gas lines, and tips on what should be done now to prolong the serviceability of current lines. Very helpful! When I was writing the check, I mentioned that I thought there was a discount listed on Angie's List. Nick wasn't aware of anything, and rather than take the time to look it up, I just paid the full amount. Later, when I did have time, I checked on AL to find that I should have received $75 off my bill. I left a message the next morning with Colorado Plumbing, and received a call back within 30 minutes. The person I spoke with was absolutely wonderful, and even drove to my house the very next day to deliver the check I had written and pick up another for the reduced amount. This was customer service to the max. Both the honesty and responsiveness were very impressive, as well as the excellent work completing the gas line installation. I wouldn't hesitate to use this company again and recommend them to others.
