"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!"

"Vincent and his assistant Sergei took on a difficult job of installing a stove top and a downdraft fan that posed some challenges of fitting into an existing counter space. An installer sent by the dealer failed at this task but they were careful and creative in finding solutions. We appreciated the attention to detail and their hard work - and the result was fabulous. Not least, the price was reasonable and both of them were easy and pleasant to work with. No hesitation in recommending their services."

Family owned business with over 22 years of experience -Remodeling - General - Remodeling - Kitchen & Bathroom - full home remodels - room additions - ADU's - Full Roof replacement -

"Would not recommend them to anyone. We had the worst experience with these guys. Scope of project: kitchen complete remodel, replacing carpet flooring with vinyl tile flooring , redo electrical for kitchen area only cost: 100K+ what went to plan: - kitchen demo - made one nice dry wall - setting up and framing of the kitchen area what went wrong: - communication/scheduling : we would never be told ahead of time when work was being done. Sometimes there would be days stretches where no one showed up and then guys would show up randomly on a Sunday morning. At the start of the project we told them we were going to move into the back half of the house, so just have that clean. We moved into trash and debris everywhere. They also saw a vinyl strap , strapped to our tree, tied to our neighbor's fence (it was there keeping the fence up as the tree was leaning into the neighbors fence). In their brilliance, they decided to cut the strap and use it for themselves. How did we know? we found it on our roof, used to tie some electrical conduit. Who the heck does that?! We should've cut ties at that point, it was just the start...if we only knew. But we gave them the benefit of the doubt...but things kept going wrong. - Kitchen cabinet install was not leveled, we end up telling them to not bother coming back and we installed the whole kitchen ourselves (re-leveling the base cabinets, putting on the hardware, installing the cabinet doors. - broke several custom panels (to their credit, they did pay for the reorder) but we ended up installing it ourselves , which we were never offered refund the labor. - the kitchen counter was not leveled, we also had to redo it ourselves in order for the independent countertop guys to install it. - cut hole for electrical switch too big, huge gap now in our org Eichler panel that is not repairable unless we replace the whole wall. - cut hole in wood beam ceiling too big for ceiling vent even though they had the manufacturer's specifications. tried to fix it, but it looks terrible. - lied and said they had experience installing lux vinyl tile. They didn't. The flooring , which is supposed to be new, looks like flooring that has been there for years and hadn't been replaced. It was discolored, uneven, not leveled, and not even lined up. How can you mess up lining up squares? Our sales person Joe ,came and made excuses after excuses , telling us " no one can install it better than them" , that this is the "best" we'll get. I cannot believe he could look us in the face and say that. We ended up requesting 1500 back, though for us to reorder redo the tiles for the kitchen will be 3K+. - as a last F you to us, they gave us the bill for the permit fees which includes a 3% of project cost recycling deposit that is 100% refundable if they just do the paperwork and let the city know where they recycled the demolition material. Our kitchen project was 80K and so it was $2400. Guess what, they "never heard of this" and have no proof of where they recycled the material and so cannot get the refund. I have no idea where they dumped the material.....and we're out 2400. The best thing about this project is finishing and NEVER having to deal with them again."

FAQs for plumbing installation for a remodel or addition projects in Los Altos, CA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
