Get matched with top tankless water heater repair pros in Oldsmar, FL

"Two old shower pulls were hard to work and one leaking profusely. Also, water heater not making lots of hot water and 12 years old. Asked for a flush and recommendation for replacement. Tech showed up on time and ready to work. Rebuilt pulls quickly and knowledgeably. Attempted to flush water heater but too far gone. Showed me work done and patiently listened to and answered all my questions concerning replacement options. Gave me a good deal on new water heater and was available and ready to install same day. Completed the installation cleanly and efficiently. Couldn’t be happier with the experience. Tech (I’m sorry, I don’t remember his name) was professional and courteous and worked efficiently. Prices are fair and their use of a standardized pricing guide eliminated any feeling that they were pricing on the fly. Two thumbs up."

"I called Cass in November 2021. The hot water heater went out the day before Thanksgiving. Richard, the service repairman, came out that day and replaced the heating element. This past week, almost 7 months to the day, no hot water again. Cass was very busy but Richard did make it out in 2 days. It was the heating element again. He replaced it again and mentioned our water was very 'hard'. There was no charge because it was under warranty. I am now planning to have Cass install a new tankless water heater. I would definitely recommend Cass for your plumbing needs. Richard was prompt, personable and qualified. Customer service is great!"

"Caleb came out and did an assessment on our water heater, talked about what it would take to move it and also talked about a tankless what we heater. I was impressed with his promptness and overall professionalism. I believe his quote is good and when we’re ready to move forward it will be with him. I love that he didn’t pressure me at all and gave me good, solid options."

"Cornerstone responded to my service request and scheduled an appointment in a timely manner. They successfully repaired my plumbing issue and installed my new tub/shower fixtures. I would hire again."

"Company responded quickly to inquiry and was on-site within 24hrs. Received high water bill 5x -6x the normal usage with no visible signs of a leak. Concealed leak was found behind exterior wall. Repaired quickly same day. An additional leak was also found on the city’s curbside of the meter due to recent change out to digital meter that was not installed correctly as valve and washers where not replaced. The real customer service was received by owner Danny who provided additional information being requested by insurance company as a claim was filed due to the water damaged caused by the concealed leak at slab/foundation level."
