"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!"

"I use Counsil for the quality of their work and trust them to do it to highest city inspection standards. I had to do two replacement sewer lines. Counsil plumbing did the digging, plumbing and cement work with same people; the other contractor did plumbing, subcontracted sleeving sewer line and subcontracted concrete work. Counsil left the house as he found it. The other contractor left trash, rebar and wood and never came back. Counsil used a price master and a detailed contract, the other contractor gave me verbal price which became opaque. I use Counsil when i need quality work that meets inspection specifications and am willing to pay for it."

"This was the first time I had used Angie's list to find a contractor. I was nervous not knowing whether I would get good service. I cannot say enough about Water Heater Masters. They were so professional and did an excellent job. They showed up on time, explained my options but didn't try to influence my decision. The workman was very neat, taking care to clean up some water spillage after draining my old water tank. I cannot say enough about how impressed I was at the service I got. And the price was very reasonable. A local contractor I called had quoted me twice the price for a new water heater installation. I have no hesitation in recommending this company."

Plumbing questions, answered by experts

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.

Helpful?

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?

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?

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.
