"I want to say a big thank you to Plumbtree plumbing and rooter. I had a drain backup and called another plumbing company, who came out and cleared my drain, but 2 days later I was back to square one. Frustrated, to say the least. A friend of mine told me about plumbtree plumbing and rooter and their positive experience with them. So I called. I was impressed to say the least. When Josh, the plumbing technician came to the door, he was very friendly and very courteous. He only entered my home after putting on shoe covering to protect my floors. He assessed the situation and suggested that after he clears the drain that he should camera the line to find out why the backup reacurred. After clearing the drain he camera the line and found that I had a collapse mainline pipe. He was able to uncover the pipeline and repair it. Such a great relief to get to the bottom of my problem and have it repaired in 1 day. I definitely got what I paid for the first time around. Cheap is not always the way to go with plumbing issues. Plumbtree plumbing and rooter was well worth the money. Honest, friendly and caring. They went the extra mile for me. I would highly recommend these guys"

"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!"

"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."

Plumbing questions, answered by experts

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?

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?

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?

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?

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.
