Testimonials

What Our Customers Say

Don't just take our word for it — hear from the homeowners and businesses we've helped.

"Dallas and Jesus were knowledgeable and professional. They did the work quickly yet thoroughly and were sure to clean up afterwards. The cost was competitive without being overpriced. For my toilet installation, they charged slightly more than the big box store — the difference being same-day service and taking the time to answer all of my questions. I will call Coast Mechanical for my future plumbing needs."

Kim S.

Paso Robles

"Amazing company. Aaron, the business owner, was prompt, courteous and really knows his stuff. He installed a top of the line water softener and a reverse osmosis system under our sink. Explains everything thoroughly and gets the job done with fair pricing. We will definitely use them again, without hesitation."

Rob S.

Atascadero

"Great customer service. Professional, personable and friendly. Excellent work. After checking one outdoor faucet, they said nothing needed to be done — my fix was correct. Honest too. I will call them for any future needs."

Natalie M.

Atascadero

"Coast Mechanical has been servicing our property for years. They are professional, courteous, prompt and I highly recommend them to anyone. They maintain a high level of professionalism and are always mindful of customers and patrons during operating hours. Thank you Bob, Brian and Jennifer for everything."
