"Very honest, trustworthy and inexpensive plumbing company. I had three total estimates for the work and the other two companies just seem to want to charge as much as possible and do more work then was needed. I highly recommend Western Rooter and ask for Ryan, he’s the best!"

"I needed to replace my water heater fast. I contact Complete Plumbing and rooter and Paul responded the same day and gave me descriptive estimate in a text. Also in my email. That has never happened to me before. I was impressed. The following day he sent Arturo and I hired them on the spot. He was honest and communicated clearly what he was going to do. Also, the estimate Paul gave initially was the same final cost. I would honestly refer this business."

"Jonathan Zavala and his team are amazing!! We recently bought a house which we knew needed a little plumbing work. Of course it's every home owner's nightmare when a "little" work turns out to be a lot! We really thought we'd be stuck dealing with plumbing repairs for weeks, but Jonathan and his crew knocked out the major work we ended up needing in mere hours. We also ended up paying 25% less than other plumbers quoted. They even dealt with our nosy and cranky neighbors extremely professionally, which we really appreciated. I am blown away with the efficiency and competence of The Sewer Boyz. Easily the best hire we've made, and I will never hire another plumber again! I told Jonathan he's stuck with us for life now, haha. We will refer all of our friends and family without hesitation. If you are looking for an honest, skilled, fast, and reliable plumber, you won't find a better one than The Sewer Boyz. Just hire them and thank me later :)"

"TWO entire properties, completely remediated for decrepit cast-iron sewer pipes, under concrete slabs... from 1960s construction in L.A. County. The most thorough examination, in advance of proposal preparation, I've ever seen. Skilled plumbers and diggers, in sufficient numbers to get the job done quickly. Spectacular dust control, to void the need for visqueen of occupants' possessions; they built a "casita" of PVC pipe and heavy plastic tarps and tape. Reasonable and easy to work with. So conscientious... tenant had use of sewer pipes overnight on a big job that took over a week to complete. Completed work passed rigorous leak tests. ALL the iron below floor level is GONE and I'll never have to worry about this again."

"I absolutely love that they work within your schedule to come out to perform services requested. I contacted their office late at night and they were able to schedule Chris the manager the next morning to provide me with a free second opinion. I had another local company that wanted to gouge me for everything that I had. This prompted me ti contact Renowned. After Chris did his free diagnosis, he went to me a reassured me that my issue was not as bad. I went ahead and had Chris and his team repair the section of sewer that only needed to be replaced. The entire sewer line did not need replacement like the other company stated it did.. Itâ s very hard to find trustworthy plumbers these days. Im so blessed I found mine."

Affordable Plumbers FAQs, answered by experts

You must select materials that comply with state building codes, including strict lead-free requirements. Because Monrovia has hard water, PEX piping is highly recommended for repiping projects since it resists mineral scaling better than copper. Additionally, CA seismic safety standards require flexible connections and double strapping for water heaters to safely accommodate any potential earthquake movement.

Helpful?

Always hire a licensed contractor who carries workers' compensation insurance to protect yourself from liability. A qualified professional will handle pulling the necessary permits for your plumbing work. Choose a local expert experienced with older homes, as they understand how to navigate aging galvanized pipes, clay sewer laterals, and the specific utility shutoff locations throughout Monrovia.

Helpful?

Updating older plumbing systems directly increases your home's resale appeal in Monrovia. Buyers actively look for modern copper or PEX pipes over aging galvanized steel. Completing permitted plumbing upgrades also demonstrates code compliance and removes disclosable defects required by CA law. Upgrading to water-efficient fixtures is another smart move, as local buyers highly value conservation efforts during droughts.

Helpful?

You are responsible for coordinating directly with your local utility provider for main water shutoffs. You must also select compliant water heaters and fixtures that meet CA energy and lead-free standards. Additionally, you will make decisions regarding the scope of sewer lateral replacements and coordinate your schedule to ensure the contractor can complete required inspections for permitted plumbing work.

Helpful?

Start by inspecting exposed exterior pipes and irrigation systems in late fall before occasional winter cold snaps hit hillside homes. During spring, check your sewer lateral for root intrusion after seasonal rains, especially if you have mature trees. In the summer, monitor outdoor plumbing heavily to prevent water waste and comply with local conservation rules in Monrovia.
