"Very professional service, technician was on time. Wayne did a great job, and replaced my propane water heater. Very pricey, but great quality work."

"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."

"Happy with their installation of an add-on electrical box, so we could get our new electric tankless water heater up and running after Hurricane Irma wrecked our old tank water heater. Very happy with our continuous hot water."

"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!"
