With our stellar plumbing services, we will get your plumbing system back to working at its best in no time.

We serve San Jose, Milpitas, Santa Clara, Campbell, Saratoga, Mountain View, Los Altos, Los Gatos, Sunnyvale, Fremont, Newark, Union City, Redwood City, Atherton, Menlo Park, and Morgan Hill. We specialize in complete plumbing services, including drain cleaning, clogged toilet repair, sewer replacement, cleanout installation, water leak repair, water system repipe, water service replacement, leaky toilet, household gas testing, household gas system leak detection, gas line repair, gas system repipe, gas leaks, water heater maintenance, water heater repair, water heater replacement, tankless water heater installation, tankless water heater maintenance, and tankless water heater repair.

"Our potfiller kitchen faucet began to leak at the wall. Great reviews on Yelp and Nextdoor prompted us to contact Plumbtree Plumbing. Their online appointment facility was very easy to use; an appointment was secured for the same afternoon. A very professional, courteous, and personable plumber, Bruce, diagnosed the problem and made an expert repair for a reasonable cost. We were very pleased. Bruce was genuinely concerned about our home's plumbing. Without any sales pressure at all, he and his equally expert associate, Matthew, made an inspection of our water pipes and discovered three issues: 1) the "water shutoff valve" at the base of the house was actually a gas shutoff valve!, and 2) a number of our water pipes were galvanized pipe instead of the desired/required copper pipe. While under the house, Matthew spotted issue # 3) and photographed it: one of our heating ducts had become disconnected, thus pumping hot air into the crawlspace! So, we are having Plumbtree Pumping come back to make a thorough estimate to correct items 1) and 2). (And our HVAC people will fix item 3)!) Please strongly consider using Plumbtree Plumbing for all your plumbing needs!"

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

Subcontractors questions, answered by experts

Most commercial projects take 3-7 days, including curing time, depending on size and weather conditions.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

A contract should outline the scope of work, timelines, costs, payment schedule, and materials used for clarity and protection.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.
