Best Water Pressure Valve in Washington DC

Blake helped my understand my problem better and saved me money by avoiding unnecessary work, despite it meaning less work for him - hugely thankful!

Used them to install a new AC along with other residents in my building, didn’t handle any of the coordination for that so overall good experience and HVAC.
BUT 6 months later tried to schedule a HVAC and plumbing inspection for my building requirements, called and left voicemails 3 times and scheduled an appointment through their website for them to call and didn’t get a call back. Only got an answer by emailing Jimmy directly with the email I had from the HVAC installation, he said the front desk lady will call to schedule, she never did. 3 more calls later I finally get someone and get an appointment scheduled. Technician arrived 2 hours late with no clue what he was supposed to do even though I sent the requirements with clear instructions on what to inspect. Inspection itself was ok, technician seemed knowledgeable, but was obviously rushed and even said he had to hurry out because he had other important calls to get to. Never received an invoice for the inspection to provide to my building, have called twice since the inspection and left voicemails and still haven’t heard back again.
Tl;dr, they do fair work but good luck getting in contact with anyone, getting technicians to arrive on time, and getting everything covered that is needed. Will be going elsewhere for my next home needs.

We had Sami’s plumbing replace drain lines under our bathroom sink, install a main water shutoff and a pressure reducing valve, and repair the overflow line from our tub. Eric came out and did the job. He was very professional and also very personable. We’ll use them again for our plumbing needs!

Needed a backed-up sink unclogged, and knew that this ongoing problem was due to a flexible pipe (not up to code) used when the bathroom was updated years ago. Called the 2 plumbers I'd used before - no availability for several days/a week. With handwashing a priority, this was a no go. Abe was able to come the next day, in a 11 a.m. to 2 pm window. Asked me a couple pertinent questions, asked if I could text him a photo of the pipe in question, and gave me an estimate. He called at 10:30 am the next day, arrived right at 11, wearing mask and gloves. Whole thing fixed in half an hour. All new pipes, and sink plug. Slim guy, so working in a tight bathroom didn't slow him down. Had me check everything out before leaving. Can't speak to value - everything with plumbers or electricians is crazy these days.
