My outdoor faucet had started leaking and needed replacement before temperatures dropped. Superior Plumbing & Heating dispatched Trevor, who installed a new frost-free hose bib and tested it thoroughly. The installation was clean, and the explanation on winter protection was helpful.

A cracked outdoor spigot needed replacement before temperatures dropped. Julian installed a frost-resistant fixture and tested the water flow carefully. The new setup feels sturdy and secure.

After dealing with a flooded basement last year, we decided to install a sump pump backup system. The team did an amazing job setting everything up and walking us through how it works. It gives us so much peace of mind now. Clean work, fair pricing, and very knowledgeable!

Kurtis was quick, knowledgeable and professional. This wasn’t a complex job, but it was New Years Eve, and I was very happy he could and did solve the plumbing problem in my house. Thanks Kurtis

Matthew was a big help with our severe blockage in our kitchen. He provided a full explanation before proceeding and promptly got rid of over 25ft of blockage. All plumbing is working great now. Big thanks.

My shower drain was completely clogged, and water started pooling during every shower. Their plumber arrived promptly and handled the job with impressive skill and efficiency. They removed the blockage thoroughly and ensured the drain was flowing perfectly before leaving. The entire experience was smooth, and they left the bathroom clean afterward. It’s clear they care about delivering quality work and customer satisfaction. I would definitely use their services again.

Farid was very good. Super communicative and willing to answer any and all questions. Went out of his way to offer great client service. Caveat though that I found price a little high…
