We lost hot water on Friday evening. We decided it wasnâ t an emergency, but we did want to get the process started to replace our water heater. I checked Agniâ s list on Saturday and a few referral names came up. I was contacted by CORE MECHANICAL within a short time the same day. I explained our issue with Tanya and she set an appointment. She was very professional and we related to each other quickly. I received 2 other inquiries on Monday morning, but they were not available until later in the week. Loren contacted me, came to my house and made his recommendation as well as gave me a quote for replacement. I was a bit shocked with the price quote because of info Iâ d read online, but realized it had been old information. We talked easily about a number of subjects and he was very courteous as well as explained the process clearly. Levi came as promised today, Tuesday, and with an assistant completed the job including cleanup and hauled away the old (25+ year old water heater) within an hourâ s time. I was very satisfied when hot water was available very soon after that. I greatly appreciate all of the employeesâ professionalism, courtesy, efficiency and communication. I highly recommend this local business.

They were courteous, professional and knowledgeable. They called the day I put in the request and came out and took care of the issue the next morning. I will definitely use them again.

They replaced both the shower and tub with new Faucets on the same day as schedule at a great price. They cleaned up after the work and were there when they said they would be.

My installation of a new tankless water heater, repiping the house and installing a soaking tub went so smoothly. They completed the entire job in 2 days!! Loren is a skilled professional. He and Levi were very focused on doing the best job. Extremely thorough and personable. I highly recommend Core Mechanical.

Levi has been fantastic! He did both the quote and the work needed, which was moving plumbing up from the basement to the first floor for our washer. Levi provided us the best quote and the quality of work was worth its weight in gold. He is very professional, prompt and was able to get everything done within a couple of hours and on budget. If you are considering plumbing work, I highly recommend this company.

I called and got a phone call back. Levi said he would be at my house in 30 minutes to repair a leaking faucet shut off. He showed up and performed the job quickly. I plan on hiring the company again.

Levi arrived early and was able to generate a quote for gas lines quickly and right on the spot. The price was agreeable and he went to complete the job that same day. Furthermore he provided me with good logistical advice and a recommdation for whom to contact for the next step of the project. Great job!

I had a leak both in my kitchen sink and my bathroom sink. The kitchen was obviously the worst. I always get 2 estimates. Levi with Core was my second. The first company quoted me at $2200. Levi noticed something that the other guys didn't mention; there was an obvious hole in the bottom of a kitchen pipe. He was able to complete repairs on both sinks in about 2 hours. I'm so glad I got a second estimate. I waited about a week to this review, just to make sure the plumbing was working.
