Company Overview

I handle setup, service, and repair of hot water systems, fixtures, toilets, purifiers, gas safety valves, instantaneous water heaters, and also perform sewer cleaning, jacuzzi service, sewer repair, gas system setup, and water piping repair and placement. My aim to ensure a uniformly excellent quality of support, based on careful analysis of problems and open dialogue, along with careful execution of the necessary tasks.

I earned my credentials at the suggestion of my first mentor, Bright Winn in San Francisco, for whom I was employed for more than a decade. Subsequently worked for 8 years with the owner of Lipsey/Mill Valley Plumbing, while serving a developing customer list as well.

The closure of the company in the year 2000 motivated me to operate Daystar Plumbing full-time, continuing service in Marin, San Francisco, and San Mateo County as I had with the previous company, and to carry on guarantee work with Kohler Co., Bosch, and various brands.

I appreciate to these two individuals for the invaluable experience and understanding I learned from their mentorship.

I brought my well-equipped Daystar service truck to serve Mike's clients, easily changing branding signs for the two businesses as needed.

I maintain very friendly terms with Bright and Mike, and ex-colleagues of those businesses.

I began doing plumbing for a community member, my neighbor, in 1982 after returning to SF from my teaching stint in the Far East for two and a half years.

I have a strong commitment about sustainability, and have made several trips with a team to advocate the U.S. Congress, the White House and international organizations regarding environmental protection and the natural world at my personal cost.

I have been actively involved in environment-oriented issues, helping to defeat poorly planned developments, and am currently active in Pacificans for Sustainable Development, Pacifica Climate Committee, & the city council-selected ""Task Force for Climate Action"".

I enjoy reading ""Scientific American magazine"", ""Scientific American Mind magazine"", ""the publication Science News"", and ""the publication Parabola"" from start to finish each issue.

Tim was very helpful in pointing out the problem to me and recommending a larger crew plumbing company and gave me some great suggestions on what to ask for. He was patient and took the time to explain the problems to me. Would definitely recommend.

I highly recommend Tim Cowan of DayStar plumbing. Very knowledgable, professional - he did not try to cut corners......I cannot tell you how reasonable priced he is. We had a leak under our kitchen sink....found out that the dishwasher was backed up with goop too. He replaced the airgap on the garbage disposal with a copper one and gave us a new hose also. He replaced the leaky chrome extension piece at the drain. and snaked the disposal...
He is very fair and honest......what plumber does that anymore !!!! He is local in Pacifica - his card even includes his address, and business license. So happy I found him. !!!!

I highly recommend Timothy Cowan, owner of Daystar Plumbing. He is knowledgeable, professional, explains what is happening and what your options are - - and is VERY honest and fair. You cannot go wrong with Timothy!

We woke up after a big storm and thought I heard drip, drip, drip coming from our garage. Oh dear, is the roof leaking? No, not the roof. But it was lucky that I heard the dripping because it turned out that our water heater had just blown. No hot water and the possibility of 40 gallons of water emptying into my garage.

I immediately called Timothy Cowan, owner of Daystar Plumbing. And he answered on the third ring! We have used Timothy's services before to install two high profile toilets and a new kitchen faucet and were very satisfied with his work and his honor/work ethic.

He quickly drove over to ascertain what the situation was. Discussed replacement of standard water heater or moving over to tankless (we asked him and he gave us pros and cons).

We made our decision to stay with electric tank water heater and he said he'd be back the next day at 9:00 am with everything needed to complete the job. And he was! We are very pleased with the repair and bringing us up to code for safety.

Timothy is your go-to man for your plumbing needs!

Thanks, Timothy! The advise you gave me was right on. Even though we didn't work together, I will keep your number for repairs that are not under warranty!

If your looking for an honest great Plumber, Timothy is your guy! I called him today with an issue I was having with my toilet leaking. He said send me some photos then call me back. I did and he talked me through the very simple task to fix the leak. No charge!!

Thank you so much Timothy!!!!

Timothy was great, very professional and made sure I understood exactly what he was doing when he came out to fix a clogged bathtub. I really appreciate his professionalism, I live alone and would recommend him to anyone needing a plumber.
He even cleaned up the yuck in the tub when he was done. It's possible he left the bathroom cleaner than he found it.

I've had two wonderful professional experiences with Timothy at Daystar Plumbing. Years back he installed a new standard hot water heater for me. As happens, the hot water tank went out and very quickly he was able to install a new one. During a remodel, the standard tank was replaced with an on-demand unit. After many years, it experienced an issue and I was unable to have the company that installed it come back. Timothy came over and troubleshooted the issue -- though it wasn't a brand that he usually services -- providing a short term fix until I could get it fully operational. Greatly appreciate his kind manner, professionalism and willingness to troubleshoot problems.

As a mechanical engineer, I really appreciate a plumber I can talk to for expert diagnosis, advice, and recommendations. Timothy communicates his work and pricing in a way that is clear and transparent. He is a professional I can easily trust.

Timothy is incredibly helpful and has wonderful customer service. I was not able to book him for his plumbing services, as he was already booked. I read glowing reviews about him on Nextdoor.com and needed a plumber same day. Even though he wasn't available, he still asked what my problem was and identified the issue. In addition, he provided a few recommendations for other local plumbers that may be available.

Thank you Timothy at DayStar for providing excellent customer service! I will definitely call you the next time we need a plumber!

Timothy was great. He was able to repair our water heater the same day that we called him and he saved us from having to buy a new water heater. He's a friendly knowledgeable professional helpful guy who knows how to safely and correctly solve plumbing and gas problems. He showed up at our house exactly when he said he would. He does work alone, so you may find yourself wanting to help him track down parts in order to save his time and your money.
