Don't touch them. These plumbers did a very average job, charged an exorbitant rate for a small amount of work. A plumber and apprentice arrived and of course we were charged the hourly rates for both. The plumber at the high hourly rate took off for almost 2 hours to buy a faucet. We provided the rest of the material for the laundry tub. Basically, the apprentice without supervision did the work.
Within weeks after the new faucet had been installed in one bathroom, the sink has cracked and must be replaced. The only bathroom sink they touched and it cracked - seems to be more than a coincidence. My husband is a senior and clearly they thought that they could take advantage of him. I asked as to the cost prior to the finish of the job and they said an invoice would be sent to us - it was and it was absolutely ridiculous - the cost of small parts were magnified by as much as 600% (we checked). We had a senior plumbing contractor review the invoice and the work and he was not impressed whatsoever. Proceed with caution and get a firm estimate as to cost and a warranty as to the work to be done so that - like us , you will not have to employ another plumber to fix any damage.
