"We purchased our house that has a water treatment & purification system and water heater that was installed by Mermaid Water. We have had them out for system check and to help us understand how to use the system. They also helped correct an item from house inspection regarding the water heater. They have been extremely helpful and responsive. Brent does an excellent job of making sure that the customer is happy."

"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"Our water heater stopped working overnight and we contacted Done Rite Services in the early morning to diagnose the issue. They immediately responded and said someone would be out to the house later that afternoon/evening. Edgardo called later in the day and asked if he could come out earlier. Upon arrival he took the proper COVID precautions and wore and mask and also ensured he covered his shoes to protect our floors. After diagnosing the problem and considering the age of the water heater and the overall installation not being up to code, we decided a replacement was needed. Edgardo thoroughly and patiently described the options for a replacement water heater and quickly checked if they were result in stock. After deciding on a model, he was able to schedule an installation in about 24 hours! During the replacement, Edgardo and Ethan were very thoughtful, respectful, and thorough, ensuring they took care to install the water heater correctly and to code. They were both wonderful to work with, very professional, and caring to make sure the installation was correct. We will definitely consider them for future plumbing work!!!"
