Red Wrench Plumbing
Company Overview
I focus on kitchen, bathroom, and laundry renovations. I install new water heaters, whether they are tank-style or on-demand. I repair or replace gas lines. I fix various leak issues. I construct residential and commercial kitchens, from the underground piping to the final touches. I engage with inspectors, owners, and architects to address any problems that occur. I take care of small plumbing jobs, including faucet, garbage disposal, and toilet repairs, replacements, or installations. All work is done to a high professional standard. I do not offer drain cleaning services.
I have spent ten years plumbing in San Francisco. At the beginning of my business, I was responsible for all plumbing for one general contractor. The majority of my work lately has been with build-outs, remodels, and trim for the same general contractor. I continue to work with them, but I am now available for my own jobs.
I come from Birmingham, England. I’ve worked as a plumber in SF for a decade. I take pleasure in plumbing, fixing issues, and finding solutions. I obtained my plumbing license in 2011. I reside in San Francisco and am raising my family here.

Recommended Customer Reviews
We run 8 businesses in San Francisco and Sean is our go-to maintenance/repairs/plumbing guy every time we have an issue. He always responds promptly to our calls (usually within a matter of minutes), and rarely do we have to wait more than a day for him to come service our restaurants/bars. He prices are fair, and his invoices are clear with no hidden fees. He is completely honest about what work needs to be done, and what is within his realm of expertise. Sean is efficient, fast, and reliable. He also has great referrals!
We hired Sean to help move some plumbing and prepare for some sinks installations for our remodel. He was super available, returned several times to follow up, and made our complicated project more manageable. Sean is great! He was super professional and did a great job.
Patricia O.Sean understood that fast repair was of the essence. My sink kept dripping at the rate of 30 seconds filling a glass of water. He showed up fast, and fixed the problem, advising me how to fix the issue myself in the future. Great, honest guy!!
Jaretta O.Sean gets the plumbing job done! Our bathroom sink had a leak and I called up this professional to diagnose and stop any contribution to the CA drought.
Sean fit me into his already stuffed schedule, made his suggestions and went above and beyond to get the right equipment in quality delivery.
Do you want your plumbing problems to leave ASAP from a friendly, knowledgable and legit plumber- call this Scottish badass pro up- thanks Sean- I'll always call you when plumbing issues arrive!
Kerri R.Sean was great! I called him regarding a leak between my retail store and the apartment unit upstairs. He came, fixed the problem correctly and was very helpful. We had a different plumber out earlier in the week who apparently didn't do a single thing! He honest plumber who shows up on time and fixes the problem. We will be calling him from now on for problems in the store without a doubt.
I had a leaky shower faucet and Sean came out to take a look. He assessed that I could probably do the work myself and recommended a couple of shops to find new valves. So while I don't have a opportunity to review the quality of their work I would definitely rate Red Wrench high for customer service and won't hesitate to contact them again if I need plumbing work in the future.
We had a pressing need and Sean was incredibly responsive and managed to come within a few hours although he had a busy schedule that day. I am very happy with his work and would not hesitate to call him again. Although my location might show as PA, my home is in Bernal Hts.
Sean is an exceptional plumber. He is reliable, responsive, prompt, reasonably priced, extremely competent and also happens to be a really nice guy. I recently renovated my entire kitchen and Sean did all the plumbing work, including taking care of the permits. He moved my sink to a new location and provided separate shut-offs for each water line (hot & cold to sink, hot to DW and cold for icemaker in fridge). He also updated the gas connection to my range. The old valve used to come out into my kitchen cabinets, but Sean placed the new one neatly inside the wall. In short, he did an outstanding job and I highly recommend hiring Sean McGrillen of Red Wrench Plumbing.
sandra m.Sean was awesome to fit me in last minute on a Friday and arrived exactly when he said he would. He was professional, quickly assessed the situation, fixed the problem, and was reasonably priced. Well done!
Jeffery C.Sean is a great plumber and you get the sense you're dealing with a really down to earth, honest guy. He came over with almost no notice and fixed our leaky faucet. We had an AirBnB guest coming that evening and really needed things to be working right. He was in and out in no time. He gave us a super good deal and we will totally get his services again.
