My one star is not due to their work, it is due to their price. I obtained an estimate to replace my pressure reduction valve for almost $570.00. I found a local plumber that did it for $250.00. The internet says that even a HIGH END plumbing company should not charge more than $400.00 to replace that part. And we all know the internet doesn't lie :)
If you want to pay for a NAME and not the actual WORK, this is the company to go with.
