Fast, clean, friendly and a great price for a job I had consisting of a new backyard spigot and some new copper in my basement. Will always use them from now on. You can't always find good, honest work. Today I did. Thanks, Guys!

Called AJD for a couple of jobs I needed done, one of them something I wanted done ASAP; I was also looking for some broad advice on water softening systems and such. We were very pleased how quickly they came out; they offered some good advice and we were very happy with the work, which was completed just a few days later at a very reasonable price.

Choose no other! David and Shannon of AJ Dauphin are great as are other members of their team.
My husband's family started using this company in the 1960's.
AJ Dauphin has provided services (water heater, toilet repair/replacement, faucets, dishwasher, etc. )at my two properties in more recent years including fixing other people's poor work. So, be careful whom you hire!
Prompt, personable, patient and skilled: that's AJ Dauphin and Son.
