The 14 plumbers serving Derry, ranked.

16 plumbing companies serve the Derry area within 20 miles, and we've read 80 of their public reviews — the critical ones first. 9 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.

Ratings run high here (median 4.8, nobody below 4.0), but the depth behind them varies: 13 companies carry 100+ reviews while others have a few dozen, which we treat as thinner evidence and say so on their cards. Where reviewers repeat a specific complaint — 5 of the 16 companies have one — it's flagged below with their exact words. One number worth knowing: Heritage Home Service alone carries 8,391 Google reviews — the deepest review base in this radius. Across the reviews we analyzed, the work named most often is burst pipes and flooding.

Updated Jul 11, 202620-mile radius of downtown DerryHow 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: 70 reviews across 14 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 ↓

Why we're cautious

  • High-cost diagnostic with questionable findings: 1 of 5 reviews describes a scenario where Paul the Plumber's $900 leak test allegedly identified failures that did not exist, contradicted by a licensed competitor's $170 test and LG distributor input (1 of 5 reviews)
  • Diagnostic pricing significantly above market rate: 1 review documents a $900 leak test charge vs. $170 from a competitor for the same service (1 of 5 reviews)
  • Potential over-specification of repairs: 1 review reports being recommended a $18k–$40k full system replacement after a $900 diagnostic, which a second opinion contradicted (1 of 5 reviews)

To be fair

  • Same-day emergency response: 2 of 5 reviews specifically praise rapid arrival during urgent situations (frozen drain, water emergency) (cited in 2 of 5 reviews)
  • Work quality holds up long-term: 2 reviewers confirm zero leaks and no issues months after repair completion (cited in 2 of 5 reviews)
  • Staff professionalism and communication: 3 of 5 reviews mention technicians being thorough, kind, calm under pressure, and educational about the work being performed (cited in 3 of 5 reviews)

How we rank the plumbers on this page

  1. We read the reviews — all of them we can get. For each plumber serving Derry we pulled up to 100 recent reviews from Google, Yelp and BBB and read the full text. For this page: 70 reviews across 14 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.
