"We had a standard water tank that failed on Friday July 1. I reached out to Matt with water issues from the tank, but more importantly- to find out options for a replacement. He convinced me to go with a popular and reliable tankless system. I called him at 7:40am, the parts were delivered at 11am and Matt came by at 1pm. By 3:30pm, our new system was operational. Going into a holiday weekend - that was fantastic service!"

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"My old hot water heater died and I needed a replacement fast. From the time I contacted them to install it took 5 days and that's including them coming out to give me a quote first. They were fast, professional, friendly, knowledgeable and the price was very competitive. The installers were knowledgeable and checked everything after install. I went from a tank to tankless unit and it has been seamless, would definitely use them again and highly recommend them!"
