"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"Once again Derry Plumbing has met all my expectations for quality work and complete professional service. Mike and Christian just removed a tub unit and replaced with a walk-in shower unit.
