Clarification: I agree with growler on most of his points, I do not agree that in general, people are stupid and should be charged every last penny ~~ etc. I beleive in fairness, we've been in business since 1980, our reputation of being fair honest and competent has been the reason we have kept our customers for so long. We don't do residential work, but our commercial customers for the most part, don't even bother to get competitive quotes anymore.
