Our verdict
Fast emergency response and solid workmanship, but expect bills 50-80% higher than quoted and potential scope creep on complex jobs.

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
2 of 5 reviews document failed diagnoses and wasted customer money: septic system job resulted in $471 total with zero problem resolution; clogged line job charged $102+ above quote despite 30-min labor
“drilled hole in drainage pipe to septic, didn't solve anything”
1 more cited review
“quoted $110/hr, got bill for $202 for 30 minutes work”
Red flag
Hidden billing practices: Reviews reveal undisclosed rounding (30 min + 1 hr 10 min travel = $202), equipment fees, mileage surcharges, and credit card penalties not mentioned in phone quote
“quoted $110/hr, got bill for $202 for 30 minutes work”
Significant pricing discrepancy: Customer quoted $110/hr received bill for $202 for 30 minutes work; invoice included undisclosed charges (equipment use, mileage, travel time rounding)
“quoted $110/hr, got bill for $202 for 30 minutes work”
Poor judgment on complex jobs outside core competency: Drilled hole in lead drainage pipe to septic system, hit cement block, failed to diagnose actual problem, charged $361 then additional $110 for incomplete work
“drilled hole in drainage pipe to septic, didn't solve anything”
Unprofessional customer service: Owner 'talked AT' customer refusing negotiation; staff parking violation showed lack of courtesy in shared spaces
“quoted $110/hr, got bill for $202 for 30 minutes work”
1 more cited review

The evidence — in reviewers' own words
Critical
“I just got off the phone with Patrick, from Glenn Plumbing. I very much appreciate his time and patience with calling me back. I have been educated, and I am surprised and disappointed. First, the good. The gentlemen who came out were professional and got the job done quickly and tightened the pipes back carefully to avoid leaking and adding cost to the job. Very good. The bad: I was quoted $110/hr plus …”
“I came home today to see a Glenn Plumbing truck parked partly in my neighbor’s parking space and partly in mine. When operating in a condo community, one should have the common sense and courtesy to park in one space — and preferably not in a space reserved for residents. This was extremely inconsiderate, I had to get out of my vehicle on the passenger’s side because of the way this vehicle was parked.”
“So my wife called Glenn Plumbing to perhaps detect a drainage issue to our septic tank. The “ Technicians” drilled a 2” hole in lead pipe to septic system and used a snake to unplug. They said it was hitting something? Umm that was the cement block in septic! I called another plumber and they emptied the septic tank and placed a riser for easy visibility to view tank level And they noted possible drain field issue …”
Positive
“Can’t say enough good things about Glenn Plumbing. Patrick and Matt helped us out big time at our business. We had a plumbing issue that shut us down. They got to us quickly to identify the issue and minimize down time. Great honest local people. Highly recommend!”
“We needed a new hot water heater. Called another plumber, got an expensive quote, and it would be over a week until they could do it. Thankfully, I called Glenn Plumbing for a second opinion. They got me a quote within 45 minutes that was nearly half of what the other plumber quoted and they had it installed by 9 am the next day! Very pleased with my experience with Glenn Plumbing!!”
