These guys truly renewed my faith in contractors. Their work is impeccable. I was an engineer for many years and I've seen my share of jobs gone wrong... needless to say I secretly checked their work after each day of construction and was thoroughly impressed with their attention to detail. This quality remained consistent from day 1 to completion. I was unexpectedly briefed by the crew nearly everyday regarding the progress and periodically questioned on my concerns... My only concern was not having one... :-) I found my mason.
Pros: Quality, Honesty and Integrity.
Cons: None... It was a pleasure!
