Armstrong has proven to be the best plumbing company I have had work on my home. They answered and replied immediately to my inquiry, arrived in a timely manner when they said they would, and hustled during the time they were at my home performing the necessary work. As a very pleasant surprise, they even discounted the work they originally quoted me, a very significant amount! Their honest and hard-work ethic has been very impressive, the work they performed at my home is beyond satisfactory, and I will be a customer for life.
