What reviewers praise
Same-day water heater replacement: called at 10 AM, installed by 2 PM — 3-year repeat customer pattern with owner Jason personally named
Cited in 2 of the 93 reviews we analyzed.
Free estimates without service-call fee; sewer line quoted vs. big-name car-price estimate and completed at fraction of cost
1 cited review
“After a horrifying experience with a sewer line backing up into the house, we contacted big-name plumbing company. They seemed like aggressive sales-people rather than anything else. They only gave me 1 and only 1 option which would cost about as much as a new car. So we found Calvert Plumbing and Backflow Services online. I called the number and actually spoke directly to Jason, the owner of the company.”
Cited in 2 of the 93 reviews we analyzed — 1 cited review not excerpted here.
Customer-first approach confirmed: proactively called county to reschedule backflow test rather than bill customer twice for overlapping due dates
1 cited review
“We use Calvert plumbing for backflow testing yearly for a very responsible price! We were admittedly late this year. Since we had already winterized our outdoor sprinkler, it was recommended to call the county & request for rescheduling to synchronize our due dates at the expense of the company. They could've gotten $$ out of us now & again in the early summer when it's due but instead looked up the number for the county office & told me what to say to get the schedule changed.”

The evidence — in reviewers' own words
Positive
“Outstanding customer service! I called to schedule a backflow inspection. I was scheduled for service the same day and the report/results were filed with the county the same day as well. Jason and the technician were extremely friendly. This was my third year using this company and i will definitely be using them again. Highly recommend their services!!”
“Actually, this is my second experience using Calvert Plumbing. On both occasions, it was a positive experience. Jason and Zach are professional and courteous and the work was performed efficiently and to my satisfaction. I will definitely use Calvert Plumbing in the future and will refer family and friends. Great service.”
