"Edgar led the project . He and his team were timely, knowledgeable, trustworthy and conscientious. The most caring and thoughtful plumber I have ever worked with. I have an old house so future plumbing issues will arise. Aaron’s is the first and only call I will need to make."

"very well. Glenn called me within minutes of my online request and he was very helpful and honest. He did not think I needed a plumber for the type of job I need. Nonetheless, he even made himself available to help by facetime. Great experience and I will contact him in the future if I need any plumbing services"

"Rarely write reviews, but I had to take the time to recognize the incredible service I received from Green Arrow Plumbing. From start to finish, this was hands-down one of the best service experiences I’ve ever had! I originally called for a relatively simple job replacing a shower head but while they were here, I also mentioned a persistent issue with my main house drain being clogged. Without hesitation, they jumped into action and took care of both problems quickly, efficiently, and with zero mess left behind. They were punctual, professional, and friendly . They explained everything in simple terms, gave a fair and honest quote, and stuck to it. No upselling, no surprises just quality work done right the first time. If you need a reliable, honest, and highly skilled plumber I highly recommend Cornelio. I’ll definitely be calling them again for any future needs. Thank you for making what could have been a stressful situation completely stress free!"

"Jesus was awesome - not only was he the first to respond to my inquiry, he fit me in quickly after a weekend and did the best job of any plumber I have ever had service my condo. Not all plumbers do a thorough or ideal set up and Jesus corrected what was leaking and fixed prior issues. Personable, professional, and reasonably priced, I am definitely hiring him again for any future plumbing work!"

"The owner, Mike, came to inspect the problem (DIY mess left by me. A half threaded part of shower arm stuck behind) and then proposed a solution which he trusts his job team lead, Manuel, could improvise as needed to avoid cutting through tile walls to minimize damages (and implied later headache and hidden cost). Which all other bidders all included cutting the tile wall without patch-up post job done. Mike was a very good negotiator and flexible at coming to a bid price I cannot not wait and compare. Otherwise, I could lose the reasonable offer. Mike is like an openbook. After job bid approved, he immediately schedule the work for next day right at the table. Manuel led a team of 4 for my project. Manuel is a nice guy, very approachable and would explain any questions I had. Nicely getting job done. At the end, the staff even vacuumed the mess and no trash left behind. I would definitely invite Mike/Manuel team back should I need another new plumbing job to be taken care of."

"My dishwater was not working anymore and the error message showed it was a plumbing issue. Anthony from Mike Council Plumbing was my technician. He did a full check on both the pipes and the dishwater and was able to diagnose that it was the dishwasher not the plumbing. I really appreciated him taking the time to explain the issues in detail. If things break, I will ask to have him back on the job. Extremely professional and very continuous with all the Covid protocols. Great service!!!"

Plumbing questions, answered by experts

You must authorize all local permit applications and decide how to handle necessary sewer lateral repairs. When replacing a water heater, you must choose compliant fuel types and ensure contractors install mandatory CA seismic strapping. Furthermore, any exterior plumbing work requires you to make decisions regarding temporary disruptions to your existing landscaping, concrete driveways, and hardscapes during the excavation and restoration phases.

Helpful?

Address active slab leaks, failing water heaters, and sewer backups immediately to prevent severe structural damage and health hazards. Conversely, you can safely delay cosmetic fixture updates or proactive sewer inspections until the dry Los Altos summer months. Scheduling exterior plumbing work between late spring and early fall prevents complications caused by heavily saturated soils during the wet winter season.

Helpful?

Overwatering your lawn during the dry CA summers saturates clay-heavy soils, which puts immense pressure on underground plumbing. Watering near mature trees also accelerates aggressive root intrusion into older sewer lines. Additionally, pouring fats, oils, and grease down the drain creates severe sewer blockages. Finally, failing to adjust to seasonal shifts in hard water mineral content accelerates scale buildup inside your pipes and fixtures.

Helpful?

Homeowners underestimate the extensive effort required to restore mature landscaping and concrete driveways after exterior trenching. Interior plumbing updates also trigger strict CA code requirements, forcing you to upgrade venting or add cleanouts beyond your original scope. Additionally, local permit approval timelines and hidden sewer lateral failures dramatically extend project schedules. Always factor in extra time for appliance deliveries and utility company coordination.

Helpful?

Start by checking your home's construction year, as Los Altos properties built before 1980 feature degrading galvanized supply lines or cast iron sewer laterals. You must also determine the exact condition of your sewer lateral, since homeowners own the section connecting to the public main. Finally, identify your specific water service provider and pressure zone to understand whether your new fixtures require pressure-boosting equipment.
