I had a small but very difficult repair job on a pipe in a concrete slab floor. Access was thru a cubby hole in a small, carpeted closet, extremely hard to access. Al came and tackled the job like it was his own problem in his own house and worked tenaciously until the leak was fixed. Al even came back the next day to insure I was completely satisfied, or better yet, that HE was completely satisfied that I was happy with his work. His work was clean, no mess and he didn't break the bank. Al is truly a skilled craftsman.
