What customers said about faucet installation
Andrew Yerena came to evaluate and replace water heater. After thorough examination he made several recommendations. After explaining everything, he set to work. He first replaced a leaky outdoor faucet then set on replacing the water heater. Andrew is a good representative for Steve’s 5 Star. I would request him should I need to call Steve’s again.
I was so impressed with the service! Great work, great price, very respectful and pleasant.This company is very honest. As a woman dealing with repairs that made me feel so comfortable. They are my new plumbing company.
This is my Third time calling and using Red Rocket Plumbing from Apple Valley, previously in Helendale, Cal. Everyone that I came in contact is so kind and courteous. Dean Taylor was the Plumber that came out each time and I would not want anyone else or company. He is the BEST I have ever met. He knows his job well…
Excellent customer service, technician arrived right on time and completed work in a timely manner, friendly and professional with his work is outstanding, definitely is very knowledgeable in his job.
Ascent is fantastic. I’ve had them install a water heater, fix several leaks and repair kitchen plumbing. Each time they were extremely professional and looked for ways to keep the cost of my repair down. Response time was also very fast (same day within hours). Would highly recommend for any plumbing needs.
Great work . Service was timely and the crew was super communicative and friendly. Aaron was awesome and provided helpful information and repairs were done well. Would hire them for work again and recommend to others with plumbing needs.
