Red flag
Surprise-fee complaint: $450 fireplace service became $850 with a part marked up ~500%, tech over 1hr late with no call
“One of the receiver/remote had to be changed and the total price came to $850. I checked the receiver price on Amazon and it's ~ $85, so they took a mark up of ~500%!”
Red flag
Receptionist reportedly refused an urgent estimate request and hung up
“Receptionist rudely refused to consider letting me talk to a technician to just see if I could get an estimate floor and ceiling (they can't cone to give a real estimate for a week) and then hung up on me.”

“One of the receiver/remote had to be changed and the total price came to $850. I checked the receiver price on Amazon and it's ~ $85, so they took a mark up of ~500%!”

“Receptionist rudely refused to consider letting me talk to a technician to just see if I could get an estimate floor and ceiling (they can't cone to give a real estimate for a week) and then hung up on me.”

The evidence — in reviewers' own words
Critical
“I called 4 days ago requesting an estimate for a water supply replacement. Today is the soonest available appt. Since then, I've had 3 other plumbing companies come to quote me since then so I honestly forgot about this appointment. The tech called me today and I told him I no longer needed the quote. He said OK and hung up. About 40 min later I get an email with an invoice for $145. When I call the office to …”
“Unprofessional phone interaction. I called to ask about water-heater routine maintenance and a basic price range. The person on the phone refused to provide any information, made an inappropriate joke, and ended the call with attitude. If this is their front-line customer service, I wouldn’t trust them with my home.”
“I've used Tim Whistler since I arrived in the area in DC (2019), and I've always had extremely positive experiences (mostly for plumbing). But recently, our thermostat started beeping and I called Tim Whistler to ask them to take a look at our HVAC system. The person who arrived arrived hours late, and wasn't even an HVAC specialist--he was a plumber, and he wondered out loud why he was sent to my house. He did the …”
Positive
“I recently decided to replace my leaky kitchen faucet. Whistler Plumbing was able to schedule my work before the new year, the plumber was on time, he was courteous and efficient, and the new faucet is great. Very happy to have this done so quickly! I've used Whistler Plumbing for years and will happily return the next time I need plumbing work.”
“Brandon was on time, informative and quick. Will call for him again if the fireplace needs to be serviced in the future. Great service!”
