Customer Reviews

Horizon Plumbing & Piping Systems’ client talked about her experience in this review.

“We got to know Horizon because they are subcontractors for Home Depot and did the plumbing portion of my kitchen reno. Hooked up my new sink, tap and dishwasher. Phillip was quick, courteous and professional so before he left, I asked him to give me a quote on the basement toilet that has been rocking since we installed a marble tile floor. The date was made, stuck with but he arrived earlier than expected which would normally be great except arrangements were made to suite the time given.  We got through.  The quote was pretty darned close. He had to take a quick run to the hardware store. He came back, finished the job and it feels great. No more just a man’s toilet. It feels solid.” —Patricia Parsons, Google Reviews

“We called Environmental Plumbing when our usual plumbing company as well as a back-up plumber failed to respond to our calls for help with a blocked drain. Gary not only took our call but was able to come the very next morning. He and his assistant arrived on time and quickly solved our problem at a reasonable cost. They were polite, professional, and very clean. They offered tips and recommendations to help us keep this problem from recurring. We’ve already recommended EP to family members with plumbing issues and are happy to provide a strong recommendation for them here.” —Suzan Mandla, Google Reviews
