How the top plumbing pros compare
The same ServiceAgent Score components that drive the ranking, scored side by side — so you can see at a glance where each provider is strongest.
The criteria we scored against
- 1. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
- 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
| Provider | Trust (data & verification) | Recommendation (rating) |
|---|---|---|
| Discount Plumbing San Francisco | Strong | Strong |
| Magic Plumbing Heating & Cooling | Strong | Strong |
| Heise's Plumbing | Strong | Strong |
| Cabrillo Plumbing, Heating & Air | Strong | Strong |
| Ace Plumbing & Rooter, Inc. | Strong | Strong |
| Advanced Plumbing & Drain | Strong | Strong |
| Fast Response Plumbing & Rooter | Strong | Strong |
| Arch Plumbing Inc. | Strong | Strong |
How we chose these
We start from every active Google Business Profile in San Francisco tagged plumbing, then score each business on two dimensions:
Trust Score (40% of the composite, 0-10) rewards owner-verified status (claimed listings get a 3-point bump), completeness of contact information (phone, website, address, hours, coordinates, photos, service categories), and review-volume credibility - a provider with 200+ reviews is treated as more trustworthy than a provider with the same star rating but only 5 reviews.
Recommendation Score (60% of the composite, 0-10) is the Google star rating shrunk toward the category mean using a Bayesian prior. Without this step, "5.0 from 2 reviews" would outrank "4.7 from 240 reviews" - which is exactly backwards. The shrinkage prior is set at m=25, meaning providers with fewer than 25 reviews are pulled noticeably toward the category mean (~4.8).
Composite ServiceAgent Score = 0.6 × Recommendation + 0.4 × Trust. We re-compute as new reviews land and as providers claim their listings. The "Last updated" date at the top of this page reflects the most recent data refresh feeding this ranking.
What we deliberately don't do: pay-to-rank, sponsored slots that masquerade as editorial picks, or hide our formula. Sponsored slots (if/when introduced) will be clearly labeled and won't affect editorial ranking.

How to choose a plumbing pro
The ranking does the research; these five checks help you turn the shortlist into the right hire.
- 1
Start with the top of the ranking, not an ad
The providers ranked highest in San Francisco earned it on review depth, rating, and data completeness — not on ad spend. Shortlist two or three from the top before you start calling.
- 2
Get two or three quotes in writing
Pricing for plumbing work varies by scope and local market. Written quotes from a few shortlisted pros let you compare apples to apples and spot an outlier before you commit.
- 3
Read the most recent reviews, not just the average
A strong average can hide a recent slide in quality. Sort reviews by newest and look for how the business handles problems — a thoughtful reply to a bad review often tells you more than the star count.
- 4
Confirm licensing, insurance, and scope before work starts
Ask for the license number and proof of insurance, and get the full scope of work plus any parts/labor warranty in writing before any plumbing job begins. Verify the license on your state board if the work is significant.
- 5
Match the provider to your actual job
A high-volume operator is great for a routine job; a smaller specialist may be a better fit for an unusual one. Use the scorecard above to pick for your situation, not just the overall rank.

Local context
$San Francisco sits in $California's broader plumbing services market, which our data suggests has 18 actively-operating providers within the city limits and surrounding metro. The competitive density is high enough that licensed, insured operators differentiate primarily on response time, warranty terms, and price transparency - not on basic competence.
Pricing drivers in San Francisco
- Pipe material (copper costs 2× PEX; cast iron repair is the most expensive)
- Access difficulty (slab leaks + crawlspace work add hours)
- Permit + inspection cost (varies by city)
- After-hours vs. business-hours rates
What to verify before signing
- State-licensed master plumber on staff
- Bonded + insured (ask for the certificate, not just a verbal yes)
- Up-front, itemized quote in writing
- Pulls permits where required by the city
- Backflow certification if work touches the water supply
Red flags to walk away from
- ⚠️ Quotes by-the-job without seeing the work first
- ⚠️ Charges separately for the diagnostic call AND the repair work
- ⚠️ Pushes pipe replacement when a localized repair would do the job
- ⚠️ No license number visible on the truck or website
When demand peaks in San Francisco for plumbing
12-month demand index (100 = annual average). Peaks in January, troughs in September. Book in the trough months to lock lower rates.

| Job | Low | High |
|---|---|---|

| Drain cleaning (snake) | $188 | $563 |
| Hydro-jet drain | $500 | $1,125 |

What to know about hiring Plumbing
Plumbing jobs split into emergencies (leaks, clogs, no hot water) and planned work (re-pipes, fixture installs, water heaters).
What drives the price
Whether it's diagnostic vs. repair vs. replacement, access to the pipes, and emergency timing.
What to check
State plumbing license, insurance, and whether they give a flat quote after seeing the job rather than an hourly open-ended rate.
When to call
For a slow leak, sooner is cheaper — water damage escalates fast. Keep an emergency number on hand before you need it.
Why trust this list
When you need plumbing work done in San Francisco, the first hour of research is usually the most expensive part - reading reviews, decoding marketing claims, and trying to figure out who's actually a licensed pro vs. someone with a truck and a Google listing. This page is meant to compress that hour into about five minutes.
We've cataloged every active plumbing business in San Francisco, California (18 total) and ranked them by a single composite ServiceAgent Score - a weighted blend of *trust signals* (data quality, verification status, review-volume credibility) and *quality signals* (rating, review count, response time). The result is a list where high-volume, well-reviewed, complete-data providers float to the top, and where a "5-star from 3 reviews" outfit doesn't get to outrank a 4.7★ provider with 240 reviews.
Below: the ranked list (top 18), followed by what to look for, what each project usually costs in San Francisco, the red flags that should make you walk, and a methodology section that shows our exact formula. If you run one of these businesses, the Claim your listing banner near the bottom takes you through a 2-minute verification flow to get a green badge, edit your description, and bump your placement.
Frequently asked questions
10 common questions about hiring a plumbing pro in this area.
Who is the best plumbing provider in San Francisco, California?
Based on our composite scoring, Discount Plumbing San Francisco ranks #1 with a ServiceAgent Score of 8.8/10 (473 reviews, 5.0★). Magic Plumbing Heating & Cooling ranks #2 (8.7/10) and Heise's Plumbing ranks #3 (8.7/10). These rankings refresh as new reviews come in.
How much does plumbing service cost in San Francisco?
Costs in San Francisco for plumbing work span $125 - $4,500 depending on scope. $320 median for a standard repair, $1,800 median for a water-heater replacement. Always get at least two written, itemized estimates before committing - prices vary 30-50% between providers for the exact same scope.
What drives the price difference between plumbing providers?
Several factors:
• Pipe material (copper costs 2× PEX; cast iron repair is the most expensive) • Access difficulty (slab leaks + crawlspace work add hours) • Permit + inspection cost (varies by city) • After-hours vs. business-hours rates
Providers that quote without seeing the job are often the most expensive in the end - the "estimate" turns into a much higher final bill after they arrive.
What should I look for when hiring a plumbing pro in San Francisco?
Use this checklist before signing anything:
• State-licensed master plumber on staff • Bonded + insured (ask for the certificate, not just a verbal yes) • Up-front, itemized quote in writing • Pulls permits where required by the city • Backflow certification if work touches the water supply
If the provider can't or won't meet these, walk. There's no shortage of pros in San Francisco - we've cataloged 18 of them on this page alone.
What are red flags to avoid when hiring plumbing in San Francisco?
The patterns we see most often in disputes:
• ⚠️ Quotes by-the-job without seeing the work first • ⚠️ Charges separately for the diagnostic call AND the repair work • ⚠️ Pushes pipe replacement when a localized repair would do the job • ⚠️ No license number visible on the truck or website
Any one of these is grounds to politely end the conversation and move to the next provider on this list.
Are these plumbing listings verified?
All 18 listings are pulled from active Google Business Profile data, which means each business has confirmed its location, name, and contact details with Google. Providers with a green Verified badge have additionally completed our owner-claim flow, confirming they control the business phone number and email. As of the latest refresh, 0 of these 18 listings are ServiceAgent-verified.
How does the ServiceAgent Score work?
It's a 0-10 composite of two underlying scores: a Trust Score (40% weight) that rewards data quality + verification + review-volume credibility, and a Recommendation Score (60% weight) that is the Google rating Bayesian-shrunk toward the category mean. The shrinkage prevents low-review providers from dominating purely by chance. Full formula on the methodology page.
Can I get free quotes from multiple plumbing providers at once?
Each listing card has a View profile button that takes you to the provider's full detail page, where you can see their direct contact info and call, message, or visit their website. ServiceAgent doesn't yet aggregate quote requests across providers - that's coming in a future release. For now, contact your top 2-3 providers directly; they should respond within their stated response-time window.
Why does the ranking change between visits?
Two reasons. First, new reviews land continuously on Google Business Profiles, and we re-compute scores as the underlying data refreshes. Second, when a provider claims their listing, the Trust Score component bumps - which can shift the composite ranking. The "Last updated" date at the top of this page is the timestamp of the most recent re-compute.
I'm a business owner - how do I get my listing on this page?
If your business has an active Google Business Profile in San Francisco tagged plumbing, it should already be here. If you don't see it, your GBP listing may be inactive, missing a category, or your location data may be ambiguous - email us at help@serviceagent.ai and we'll investigate.
