FastPlumber near me

The 15 plumbers serving Duncan, ranked.

We read 3,538 reviews across Google, Yelp and BBB for the 46 plumbers serving Duncan — including the one-star reviews other directories bury — and ranked them the way we'd rank them for a friend. 35 of the 46 list 24/7 hours — but "open 24 hours" on a Google profile and "answered at 2 a.m." in a customer review are not the same claim, and we quote the reviews that tell you which is which. Rankings are not for sale.

Duncan's problem isn't finding a plumber; it's telling them apart — the median rating here is 4.9, and when everyone has five stars, the stars stop helping. 30 of these companies carry 100+ reviews — enough history for real patterns to show. The patterns differ more than the ratings do: 33 of the 46 have a repeated complaint pattern in their reviews — quotes that grew mid-job, unreturned callbacks — flagged and quoted on their cards below. One number worth knowing: Waldrop Plumbing - Heating - Air alone carries 7,504 Google reviews — the deepest review base in this radius. Across the reviews we analyzed, the work named most often is water heaters and burst pipes.

Updated Jul 11, 202620-mile radius of downtown DuncanHow we rank
How we rank — the 60-second version

What we read: for each plumber, up to 100 recent reviews from Google, Yelp and BBB — the full text, not just the stars. For this page: 1,396 reviews across 15 businesses.

What moves a plumber up: repeated, independent evidence of showing up when promised, fair and upfront pricing, and work that holds. One glowing review counts for little; twenty that agree count for a lot.

What moves a plumber down: repeated complaint patterns — surprise fees, missed appointments, pressure sales — especially when they show up on more than one platform.

What never moves the ranking: money. One clearly labeled sponsored slot may appear above this list; it never changes the order below it.

Our take on each plumber is our opinion, grounded in the reviews we quote on this page. Full methodology ↓

Our take — how we form it

JB Plumbing Services (BBB A+ accredited) scores 5.0/795 Google reviews with 94 of 97 analyzed at 5 stars; fast_response in 13 reviews, fair_pricing in 9, and weekend gas leak emergency handled immediately by the owner calling back personally.

Why we're cautious

  • 1-star Yelp review (Deanna Bland H.) details tech stopping a dishwasher mid-cycle without informing homeowner, leaving dishwasher still connected to plumbing and power, charging for the diagnosis, and providing no next steps. (1 of 97 reviews)
  • slow_response logged once; 1-star Yelp review describes a technician who left without disconnecting a leaking dishwasher from plumbing or power — and charged for the visit. (1 of 97 reviews)

To be fair

  • Owner Jean personally called back on a Sunday evening water heater emergency and came out same-day for an estimate — when the previous company ignored two calls. (cited in 1 of 97 reviews)
  • fair_pricing cited in 9 of 97 reviews and cheap-plumber signal in 9; Yelp reviewer described payment as "well under what I expected to pay" for tankless water heater repair. (cited in 3 of 97 reviews)
  • communication theme in 11 reviews; office sends pre-arrival tech photo for safety, keeps customers updated throughout job, and team explains every step on complex repairs. (cited in 3 of 97 reviews)
What reviewers praise

Why we're cautious

  • Two 1-star reviews from 2018 report same critical issue: initial repair claimed as 'fixed' but same problem recurred within days. Both customers felt unresponsored and unsupported for follow-up. (2 of 114 reviews)
  • After-hours support unresponsive. One 1-star review states 'after hours help hangs up the phone on you'; another notes late-night call returned next morning only. (2 of 114 reviews)
  • Resistance to emergency follow-up visits for recent failures. Customer with $30k+ account reported company refused same-day technician for AC failure 48 hours after initial service, insisted on 4pm appointment and additional $169 service call charge. (1 of 114 reviews)

To be fair

  • Next-day or same-day emergency availability even when fully booked. Multiple reviewers report scheduling within hours or next day for urgent issues. (cited in 4 of 114 reviews)
  • Consistent on-time arrivals and prompt scheduling. 6 reviewers specifically mention punctuality, on-time arrival, or same-day confirmation calls. (cited in 6 of 114 reviews)

Our sample skews heavily toward critical reviews — it disagrees with the Google average shown above.

What reviewers keep saying

  • Confirmed weekend and evening availability — sewage pump replaced on a Sunday, with on-the-spot pricing that matched final invoice. (cited in 2 of 100 reviews)
  • Sub-45-minute dispatch cited in multiple recent reviews — James arrived within 45 minutes for a drain/disposal job. (cited in 2 of 100 reviews)
  • Technicians arrive a little early, explain work clearly, and check surrounding systems proactively. (cited in 2 of 100 reviews)

What reviewers complain about

  • Pricing runs high: one Yelp reviewer found the same 3-item job quoted at $733 vs. a competitor who completed it same day for significantly less. (1 of 100 reviews)
  • Follow-through gap: one tech promised callback within a week on parts availability and forgot — took 10+ days and multiple calls to resolve. (1 of 100 reviews)
What reviewers praise
“Keith is a very knowledgeable and friendly plumber who installed my hot water dispenser easily. He was even a little early for my appointment! He took time to educate me on some other plumbing issues I may need to take care of in the future. I would …”

The most critical take we found
“I would give this a zero rating if possible. This plumbing concern is so overpriced it should be illegal. Recent experience: I waited 5 days to get an appointment for a running toilet, two bathroom faucets to be swapped out. I bought the faucets already. …”

Our take — how we form it

Polarized 4.8★ shop: 48 of 100 analyzed reviews are 5-star for fast weekend response, but 38 are 1-star — several allege severe overcharging ($4,200 sink leak, $7 part billed at $1,700).

1★10

Our sample skews heavily toward critical reviews — it disagrees with the Google average shown above.

Why we're cautious

  • Repeated overcharging complaints: $4,200 for a sink leak with a $7 part billed at $1,700, and a $7,324 furnace quote a customer matched elsewhere for $1,800–$3,000 (2 of 100 reviews)
  • A senior customer alleges the owner hung up on her plumber and gaslit her after a disputed bill — pattern of post-sale conflict (2 of 100 reviews)
  • expensive theme appears 6 times; multiple reviewers say a great first visit was followed by aggressive upsells or disputed bills (2 of 100 reviews)

To be fair

  • Weekend and emergency turnaround praised — pipe burst on a Sunday and a Saturday-evening call-out both got same-day fixes (cited in 2 of 100 reviews)
  • Several techs (Brian, Marion) flagged problems honestly — one told a customer how to self-fix and didn't charge, saving them $400 (cited in 2 of 100 reviews)
What reviewers praise
“The guy Brian came out and told us what the problem was and he didn't charge us and even told me how to fix it and I am pretty good at home fixes so I fixed myself. He saved me $400 for them to fix it. That is great service and if I do need them again I'll …”
Jeremy McCurley · ★★★★★ · Google · Mar 2026
The most critical take we found
“Beware - plumbers rarely come to your home. They send techs who just name their price. Shady deal - if I call a plumber I want a licensed experience plumber. JS”

What reviewers complain about in Duncan

The repeated complaint patterns our read surfaced, business by business — each links to the card where the supporting quotes live. How we find these →

  • JB Plumbing Services LLC — 1-star Yelp review (Deanna Bland H.) details tech stopping a dishwasher mid-cycle without informing homeowner, leaving dishwasher still connected to plumbing and power, charging for the diagnosis, and providing no next steps.
  • Superior Plumbing Services — Uncharged repair work left causing new problem: vent pipe missing in wall after technician visit, leading to toilet receding on flush; 14+ months without resolution per 1★ reviewer
  • Superior Plumbing Services — Repair cost not quoted before completion on tankless water heater drain job; post-repair run-around when filter leaked after technician handling per 1★ Yelp reviewer
  • KT Plumbing — Two no-show/unresponsive incidents on record: 1 review (2020) reports a dozen unanswered calls and no-show appointment; 1 review (2019) reports failure to follow up after initial consultation and missing scheduled Monday appointment
  • Brothers Plumbing, Air & Electric — Two 1-star reviews from 2018 report same critical issue: initial repair claimed as 'fixed' but same problem recurred within days. Both customers felt unresponsored and unsupported for follow-up.
  • Brothers Plumbing, Air & Electric — After-hours support unresponsive. One 1-star review states 'after hours help hangs up the phone on you'; another notes late-night call returned next morning only.
  • Brothers Plumbing, Air & Electric — Resistance to emergency follow-up visits for recent failures. Customer with $30k+ account reported company refused same-day technician for AC failure 48 hours after initial service, insisted on 4pm appointment and additional $169 service call charge.
  • 1-Tom-Plumber — Tech left toilet removed/uninstalled at Airbnb without notifying customer — guests arrived to unusable bathroom; documented in review U9MKYjaoLJzs5DzBi1mV.

How we rank the plumbers on this page

  1. We read the reviews — all of them we can get. For each plumber serving Duncan we pulled up to 100 recent reviews from Google, Yelp and BBB and read the full text. For this page: 1,396 reviews across 15 businesses.
  2. Patterns beat anecdotes. A plumber moves up when independent reviewers keep describing the same behavior: showing up when promised, quoting before working, work that holds. One rave changes nothing.
  3. Complaints count double when they repeat.Surprise fees, missed appointments, pressure sales — when the same complaint appears across reviewers (or across platforms), it caps how high we'll rank a business regardless of its star average.
  4. Money never moves the ranking.A plumber can buy the clearly-labeled sponsored slot at the top of the page — visibility, not endorsement. A business we wouldn't recommend can't buy the slot at all, and no payment changes the ranked order.
  5. Our take is our opinion.It's grounded in the reviews we quote and count on this page — check our evidence and disagree with us if you like. That's the point of showing it.
Every quotation on this page is reproduced verbatimfrom a publicly posted review and attributed to its author, star rating, platform and date. Star averages and review counts are Google's (or Yelp's) as of our last data pull. “Rating mix” charts describe only the set of reviews we analyzed, which we state on every card. Read the full policy — including what we do not do — on our methodology page.
