Atherton Plumbing Services: Client Testimonials

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Frequently Asked Questions from Atherton Residents
Why Is It So Hard to Find a Good Plumber?
Finding a trustworthy plumber can be challenging due to inconsistent pricing, varying service quality, and long wait times. A good plumber should offer clear pricing, provide timely service, and have the right expertise for your plumbing needs.
Why Is Hiring a Plumber So Expensive?
Hiring a plumber can be costly because plumbing requires specialized skills and high-quality tools. Plumbers invest in advanced training, certifications, and top-tier equipment to deliver reliable service, which adds to the cost of their services.
How Much Does a Plumber Cost to Fix a Clogged Bathtub Drain?
The cost to fix a clogged bathtub drain typically ranges from $100 to $300, depending on the severity of the blockage. Simple drain clearing might cost less, while more complex issues, such as pipe damage or a deeper clog, may increase the cost.
How Much Do Plumbers Charge to Unclog a Toilet?
The cost of unclogging a toilet typically ranges from $50 to $600+, depending on the severity of the clog and the complexity of the job. A simple blockage will cost less, while a deeper issue, such as a sewer line problem, may increase the price.
Do Plumbers Charge More on Weekends?
Yes, plumbers often charge higher rates on weekends or after hours due to increased demand and the need for urgent services. However, some plumbing companies offer flat rates or discounts for weekend work, so it is a good idea to inquire about pricing in advance.
