Cosmo was very accommodating on the phone and said someone would be at my home at 10:30 A.M......Perry showed up at 10:31 and apologized for being late.....He diagnosed the problem, made an adjustment on the faulty equipment and advised on what to do to prevent a recurring problem.....The whole experience was satisfying....I now feel assured that if I need major work done, I will be charged a fair price for outstanding work.......I will ONLY be calling Cosmos from now on and I highly recommend them to anyone with a current plumbing issue.
