Our shower was stuck on scalding hot, and I was afraid I’d have to replace the whole fixture. Conner took one look, swapped out the shower valve cartridge, and had it working perfectly in no time. Super professional, didn’t upsell unnecessary work, and even cleaned up afterward. Great service!

5 stars for Kevin. He provided excellent and friendly service. The cost of the service, however, was very extremely high.

Alvin and Christian came even earlier than expected to my emergency call. They were polite and efficiently went about their business in my dungeon of a basement. They worked quickly to investigate my plumming problem, and kept me informed of each step in their process. While it was bad plumbing news for me, they retained their professional demeanor throughout the two hours spent in my home. I would recommend them to anyone in the Port Hope area.

Eathon came and inspect my undetected leak. He was on time and professional.
