"We have depended on Fred and Son for expert plumbing help for years now. Today it was Joe who did the installation, and we couldn't be happier with his work. Equally important, we appreciate how friendly, considerate, and professional he was throughout his visit. We will continue to have Fred and Joe on speed dial!"

"I revoke my previous F rating. The owner, Lal Bo, made a house call to apologize and explain the situation. Lal Marin was the plumber who did not show twice. Although my plumbing problems were fixed by a different company, I will reach out to Day & Night next time I have a problem."

"Rema was very thorough when installing my new kitchen faucet. He came to my home at 6:15pm, which surprised me. In my experience, it’s difficult to get a plumber past 5pm! My faucet works perfectly and he was very nice. He said he has been doing plumbing for 20 years! I think I have found my “go to” plumber!"

"The plumber was a forward thinker and his solution to the problems was outstanding. I don't remember his name but he is an excellent plumber. I will call on them for all future plumbing jobs and ask for him by name (which I will know by then). Jon May, Gaithersburg, MD"
