The 15 plumbers serving Ashburn, ranked.

We track 60 plumbing companies working within 20 miles of Ashburn and have read 3,464 of their reviews across Google, Yelp and BBB — including every one-star review we could find. 31 answer 24/7 per their Google listings; where reviewers describe real middle-of-the-night calls, that evidence is quoted on the cards below. Rankings are not for sale.

Ashburn'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. 42 of these companies carry 100+ reviews — enough history for real patterns to show. The patterns differ more than the ratings do: 35 of the 60 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: only one company in this radius — Unlimited Plumbing & Piping, LLC — sits below 4.0 (3.9). Across the reviews we analyzed, the work named most often is water heaters and drain clearing.

Updated Jul 11, 202620-mile radius of downtown AshburnHow 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: 965 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 ↓

Caveats apply24/7 per Google listing

4.9 (3,019 Google reviews)3.5 on Yelp (100) 5.0 mi from downtown Ashburn

Our take — how we form it

Fast emergency response and skilled technicians, but pricing significantly exceeds competitors and commission-based pay structure creates risk of unnecessary upsells.

5★5

4★2

3★1

2★1

1★6

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

Why we're cautious

Commission-based pay structure linked to documented aggressive upselling: 4 reviews describe pressure to purchase unnecessary services or high-ticket replacements not supported by second opinions (4 of 192 reviews)
Alleged misdiagnosis of safety hazards to justify large repairs: 1 detailed review claims technician fabricated CO2 leak to justify $7000 furnace replacement; second opinion revealed unit was safe. Company remained defensive when confronted. (1 of 192 reviews)
Service quality highly dependent on which technician arrives: multiple reviews explicitly note some employees are 'great' while others attempt overcharging or aggressive selling, indicating inconsistent oversight (2 of 192 reviews)

To be fair

Exceptional emergency responsiveness with multiple same-day or 2-hour arrivals during urgent situations (cited in 3 of 192 reviews)
High-quality workmanship and diagnostic skills, with 8+ reviews praising thoroughness, efficiency, and problem-solving (cited in 4 of 192 reviews)
Honest consultation practices when not commission-driven: 5+ reviews mention technicians providing multiple quotes, options, and honest assessments without pressure (cited in 3 of 192 reviews)

What reviewers complain about in Ashburn

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

Service Force Plumbing — Surprise-fee complaint: $475 to snake a clogged kitchen drain and a trip fee charged with no receipt
Cardinal Plumbing Heating & Air Inc — Commission-based pay structure linked to documented aggressive upselling: 4 reviews describe pressure to purchase unnecessary services or high-ticket replacements not supported by second opinions
Cardinal Plumbing Heating & Air Inc — Alleged misdiagnosis of safety hazards to justify large repairs: 1 detailed review claims technician fabricated CO2 leak to justify $7000 furnace replacement; second opinion revealed unit was safe. Company remained defensive when confronted.
Cardinal Plumbing Heating & Air Inc — Service quality highly dependent on which technician arrives: multiple reviews explicitly note some employees are 'great' while others attempt overcharging or aggressive selling, indicating inconsistent oversight
AllTech Services, Inc — Pricing fairness dimension scored 0/100 despite 4.9 Google rating with 3,169 reviews—suggests either systematic overcharging not captured in analyzed sample or severe data collection issue. Request itemized quotes before committing.
Home Service Doctors — Critical: Catastrophic workmanship failure in 2023 where main valve exchange flooded customer's basement; company refused refund and directed customer to file insurance claim instead, admitting no responsibility despite stating work was their error
Home Service Doctors — Scope-creep billing pattern: at least 2 reviews indicate customers were charged significantly more than needed (full toilet replacement vs. wax seal; full toilet replacement when only leak repair needed) with quotes totaling $1,100-$1,280+
Service Specialties Inc. — Safety concern: 1 Yelp review from 2019 reports finger-tight gas fittings discovered by another installer, describing the situation as dangerous and potentially life-threatening

How we rank the plumbers on this page

We read the reviews — all of them we can get. For each plumber serving Ashburn we pulled up to 100 recent reviews from Google, Yelp and BBB and read the full text. For this page: 965 reviews across 15 businesses.
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.
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.
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.
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.
