The NWT Services team were professional, friendly, knowledgeable, their work was finished very neatly. They discussed and analyzed the problem. Then they Informed me on how the problem could be solved efficiently. Nick walk me through the solution. After the job was completed I was given a walk through on what was done and how too operate my valves and the safety features. They were courteous enough to inform me when they were on their way. The team went beyond the scope of their work order. I was very happy with the completed job. I feel really safe now to use my Natural gas grill and fireplace. I am happy, happy, happy and would highly recommend NWT to everyone who will listen. Great job.
