The 15 plumbers serving Ijamsville, ranked.

We read 1,288 reviews across Google, Yelp and BBB for the 30 plumbers serving Ijamsville — including the one-star reviews other directories bury — and ranked them the way we'd rank them for a friend. 15 of the 30 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.

Ijamsville'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. 18 of these companies carry 100+ reviews — enough history for real patterns to show. The patterns differ more than the ratings do: 18 of the 30 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 — Gaithersburg Plumbing Inc — sits below 4.0 (3.5). Across the reviews we analyzed, the work named most often is water heaters and drain clearing.

Updated Jul 11, 202620-mile radius of downtown IjamsvilleHow 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: 801 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 ↓

Perfectum Construction and Plumbing

Top pick
5.0 (158 Google reviews)4.3 on Yelp (6) 13.2 mi from downtown IjamsvilleNot a 24/7 shop
Our take — how we form it

Perfectum Construction and Plumbing (5.0★ Google, 158 reviews) — owner Vadim handles complex water heater, gas line, and multi-trade repairs with 10+ year repeat customers, but a 1-star Yelp contract dispute ($34k, months of inaction) is a documented red flag.

Rating mix — of the 11 reviews we analyzed158 total on Google
5★10
4★0
3★0
2★0
1★1

Why we're cautious

  • Yelp 1-star: $34k general contractor contract signed Dec 2017, zero progress for months post-signing despite verbal January completion promise — constitutes a documented performance failure on a large commercial-scale job. (1 of 11 reviews)
  • 1-star Yelp review documents a $34,000 contract signed 12/2017 where no work was done for months despite a county-approved architect drawing — project did not proceed as verbally promised. (1 of 11 reviews)

To be fair

  • Decade-long repeat customers citing precision workmanship — Vadim catches factory defects others miss, e.g. replaced anode rod on brand-new water heater immediately without leaving customer without hot water. (cited in 2 of 11 reviews)
  • Multi-trade capability (plumbing + structural + HVAC + flood restoration) means fewer contractors for complex repairs — confirmed across multiple projects over 5 years. (cited in 2 of 11 reviews)
  • Short-notice water heater replacement with thorough scope — repiped humidifier lines and replaced pressure valve and main shut-off in same visit, cited by reviewer using company since 2021. (cited in 1 of 11 reviews)
What reviewers praise

  • BBB rating is F — contradicts 4.7★ Google rating; discrepancy warrants caution despite positive recent Google reviews (1 of 6 reviews)
  • Failed to clear a drain after charging $450, then quoted $1600 for alternative method; competitor completed identical snake job for $250 (1 of 6 reviews)

O'Connor Plumbing

We'd call someone else first
4.5 (230 Google reviews)2.9 on Yelp (33) 10.7 mi from downtown IjamsvilleNot a 24/7 shop
Our take — how we form it

4.5 stars with 23 of 100 analyzed as 1-star; holiday-weekend 45-minute emergency response confirmed but poor_workmanship in 1 account and a serious allegation of workers sleeping on a client's couch during a multi-week job.

1★9

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

Why we're cautious

  • Workers documented on camera sleeping on a client's couch and going through belongings during a 2.5-week emergency repair that was quoted as 7 days — company reportedly had Google remove the original review (1 of 100 reviews)
  • Charged travel time and overtime without advance notification and without arriving within the stated time window — problem not fixed but still billed ~$400 (1 of 100 reviews)
  • Repeat faucet/fixture repairs resulting in leaks within a year — cited by 1 reviewer forced to use company repeatedly as landlord's preferred contractor (1 of 100 reviews)

To be fair

  • Holiday-weekend emergency dispatch in 45 minutes when 6 other 24-hr plumbers were unavailable for 3–5 days (cited in 1 of 100 reviews)
  • Large property-management accounts rely on O'Connor as primary resource — competitive pricing, jobs completed within quoted cost (cited in 2 of 100 reviews)
  • fast_response theme in 12 of 100 analyzed reviews; water heater and toilet replacements done in a single visit (cited in 2 of 100 reviews)
What reviewers praise
“Alec and Spencer came to change the water heater for my apartment. I must say, the professionalism, politeness and friendly personality is a breath of fresh air in this day and age. Especially when faced with inconveniences they still maintain a pleasant and …”

What reviewers complain about in Ijamsville

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
  • Perfectum Construction and Plumbing — Yelp 1-star: $34k general contractor contract signed Dec 2017, zero progress for months post-signing despite verbal January completion promise — constitutes a documented performance failure on a large commercial-scale job.
  • The Drain Guys — Charged $450 for unsuccessful drain snake then quoted $1600 for next step; reviewer confirmed another plumber did same snake for $250 — possible skill or pricing gap
  • The Drain Guys — BBB rating is F — contradicts 4.7★ Google rating; discrepancy warrants caution despite positive recent Google reviews
  • Roto-Rooter Plumbing & Water Cleanup — 1 of 5 reviews documents pipe section destroyed by heavy machinery during drain cleaning, leaving problem worse than before at agreed-upon $300
  • Your 1 Plumber — 1 review documents two consecutive scheduling failures: tech called at wrong time, then failed to arrive at rescheduled appointment — customer lost entire work day waiting.
  • Your 1 Plumber — $29 estimate fee charged before any work quoted — at least 1 reviewer flagged this as unusual; drywall cut performed ($130-180) but tech could not complete the repair they created.
  • Benjamin Franklin Plumbing of Gaithersburg — Two techs left a family without working water after a meter install they admitted to figuring out via ChatGPT and YouTube

How we rank the plumbers on this page

  1. We read the reviews — all of them we can get. For each plumber serving Ijamsville we pulled up to 100 recent reviews from Google, Yelp and BBB and read the full text. For this page: 801 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.
