After going to three different stores to find a sink plug that fit, Ambrose finally came to my rescue! With attentive customer service, I highly recommend! My only regret is that I didn’t stop here first!

Thank you Trenton from Ambrose Plumbing. I live in an 100+yr old house. He has kept us going with fixing plumbing problems around here. He is very knowledgeable and knows his job very well. Thank you Trenton

We recently had a check valve installed, along with, outside septic connection. The whole crew was friendly, professional and very respectful of our house and property. We would definitely recommend Ambrose Plumbing & Heating!

I have used Ambrose Plumbing in the past for clogged sinks, so they were my first choice when it came to tackling a bathroom renovation. My old tub was past its prime, so I made the decision to replace it with a walk-in shower. I'm thrilled with how it turned out.
From initial conversations to get an estimate for the work, straight through to picking finishes and the actual work performed, I can't say enough how happy I am. I was kept in the loop regarding how long the process would take from parts coming in, to how many days the work would take. All of the people involved were professional, communicated what was going on, and advised me of what to expect throughout the work at hand. Thank you to Brent, Cam, and the sub-contractors who created a beautiful space that I know I will enjoy for years to come.
I love it!

Ambrose is fantastic. Our hot water heater went out and they were very responsive! 24 hours after my call for help we had a brand new heater installed. Reasonably priced, great friendly and personable crew. Very professional and answered all of my questions while they were here. I would use their services again.
