The service I received from Complete Plumbing was simply amazing. Courteous, respectful of my animals and very efficient. This company is terrific. I would definitely recommend them to anyone needing plumbing services.
Just be prepared: they came 1.5 hours earlier than the appointment slot, were here for about 15 minutes, changed the cartridge and set screw and the total was $224 for labour and $20 part. Their minimum charge is $179 just to come to your house to begin with even if nothing is fixed. However guy was very nice and professional and the problem was fixed.
EXTREMELY EXPENSIVE. 700$ for 45 minutes job. Will NEVER EVER recommand.
Complete Plumbing reacted promptly, efficiently and with the utmost professionalism and honesty when I required bathroom installations and renovations completed prior to my return from an accident related hospitalization. I am beyond pleased with the fixture selection, the workmanship and the price. No hesitation whatsoever in recommending complete plumbing.
Could not repair the drain problem with the kitchen sink , still had to pay over $200.00 , left a mess , the plumbing under the sink was dripping water. Had another plumber come in who in turn solved the issue using the exact equipment and even repaired the leak . Called the company to voice my displeasure and was told someone will call me to address my concerns (which no one did) they actually left some of their equipment at my house which I called to let them know , someone came by the next day to pick it up without even a thank you
I had a pipe leak caused by the city of St. Catharines. The city said I would have to get a plumber to fix it and they would repair it. I called Complete Plumbing and explained my situation. The receptionist was very pleasant and understood my situation. She said she would see if someone was available and call me back. She called back immediately and someone would be here at 4:00. At 4:00 a very friendly young man came and checked out the problem. He said it was a simple fix. He went and got the part and was back in 5 min. Within 5 minutes he had it fixed. He said there would be no charge that the part was only $4. I was amazed. It showed me how reliable and honest Complete Plumbing is. They knew the city was willing to pay for it but also knew what I would have to do to get the refund. I highly recommend Complete Plumbing. Thank you so much. Sue Gibson.
