We had Donnelly come out to repair our clogged 2nd kitchen faucet which was done. I should have had him replace the faucet instead. Someone came out today to replace the faucet. Good company, competent staff, great at keeping customer informed. I’m glad I called them. Once again we needed Donnelly to install a new garbage disposal after our dishwasher died too. It’s the ten year life span.
