The plumber was easy to schedule and did a great job clearing the clogged drain. He did a good job of keeping the space clean, even when working through the muck.

Details: No, repair is not urgent • Only one drain has issues • Clogging • Condo/Apartment

Called for an estimate and the technician came to the unit. I’m not a fan of the lack of consistency and transparency with their prices. The service call fee was 95 according to the technician but $65 was advertised here on TT. When asking about the breakdown of the repairs between parts and labor, the answer was that they charge a flat fee $525 which seems a bit excessive for a sink drain assembly replacement. I wonder how much they charge for replacing the whole sink. The issue wasn’t so much the price as the lack of transparency with their quotes.

Details: Faucet malfunctioning • Bathroom • Sink or faucet • Condo/Apartment
