Find Nearby Plumbers In Concord, California

Julio demonstrates strong performance across all four dimensions based on consistent positive feedback. Professionalism is evidenced by punctuality, responsiveness, customer-oriented attitude, and reliability across all reviews. Pricing is described as transparent, reasonable, and fair in three reviews, with no hidden charges mentioned. Project completion is solid, with multiple long-term clients (7+ years, since 2010) indicating sustained follow-through and repeat business. Experience is clearly demonstrated through diverse project types (plumbing, electrical, construction, fencing) and technical competence. However, the sample size of only 4 reviews limits confidence despite their unanimously positive nature.

• Small sample size (n=4) — all reviews are 5-star ratings with no critical feedback, which may not be fully representative
• Three of four reviews are older than 3 years (2017, 2019), with only one recent review from 2023 — recency data is limited
• All reviews are highly positive with no substantive complaints or areas for improvement mentioned — consider requesting more recent feedback to validate current service quality

This WW Score of 89.3 should be treated with moderate caution due to the small sample size and lack of recent reviews; while the feedback is consistently positive and specific, a larger and more recent review base would significantly strengthen confidence in this assessment.

Corsa Plumbing receives consistently strong marks across all four dimensions based on 7 reviews spanning 2022–2024. Professionalism is a standout theme, with multiple reviewers explicitly praising communication, punctuality, and courteous behavior — Ray in particular is mentioned by name for keeping customers informed throughout the process. Project completion is equally well-supported, with reviewers noting jobs finished on time, promises kept, permits obtained, and even a callback honored with work coming in under quote. Experience is highlighted across nearly every review, with specific mentions of advanced leak detection instrumentation, correct diagnosis avoiding unnecessary costs, and high-quality workmanship on complex jobs involving copper line replacement, sewer upgrades, and ADU installations. Pricing is mentioned positively in three reviews, including one case where the contractor saved the customer thousands by correctly identifying that a sewer pump was not needed, supporting a strong but moderately confident pricing score.

• All 7 reviews are 5-star ratings with no negative or mixed feedback — this warrants mild caution, though the reviews contain specific details, named individuals, and varied job descriptions that reduce the likelihood of fabrication.
• Two of the seven reviews are older than 12 months (2022 and 2023); the remaining five are from within the past 12 months and carry greater weight in scoring.
• Sample size is small (7 reviews total) — scores carry MODERATE overall confidence and should be interpreted cautiously until more reviews are available.

This WW Score is moderately reliable — the reviews are specific, detailed, and span multiple job types, but the small sample size of 7 reviews and the absence of any critical feedback limit the confidence with which these scores can be generalized.

The overwhelming majority of reviews praise professionalism, punctuality, communication, and friendly attitudes across multiple technicians and owners (Aaron, Mike, Guillermo, Ron, and others), driving a strong but not perfect professionalism score. Pricing scores well overall — many reviewers explicitly cite reasonable, fair, or competitive pricing — but is tempered by several notable complaints: one reviewer was charged nearly $700 for a snake with no resolution, another documented being charged over double the market rate for HVAC maintenance, one experienced a mid-job price change from $285 to $388.50, and another felt labor charges for a warranty replacement were excessive. Project completion scores solidly given the large volume of reviews describing completed jobs, same-day or next-day service, and follow-through, but is reduced by a handful of reviews describing abandoned callbacks, a technician who left without hot water working, a dishwasher leveling issue that took two weeks to resolve, and a misdiagnosis case where a competitor fixed what A-1 could not. Experience scores high based on numerous explicit mentions of skill, technical knowledge, and problem-solving ability, including complex jobs like CIPP lining, tankless water heater repair, and leak detection under homes.

• A significant number of reviews (approximately 40) contain no text — only a star rating. These blank reviews cannot contribute usable data to any dimension and were excluded from scoring.
• Several reviews appear to reference entirely different companies or technicians (e.g., A-1 Total Service Plumbing with Guillermo/Esteban/Osvaldo/Leo vs. Complete Plumbing with Aaron/Mike Torculas). This review set appears to aggregate reviews from at least two or possibly three distinct businesses. Scores reflect the combined pool but reliability is reduced because performance may vary significantly between entities.
• Multiple reviews for 'Complete Plumbing' reference owner Mike Torculas and span back to 2011, while others reference Aaron Petrossian as owner of Complete Plumbing — these may be two separate businesses operating under the same name in different regions.
• Pricing dimension has meaningful negative signal: at least 4 reviews explicitly describe overcharging, hidden fees, or price changes mid-job, which significantly tempers the otherwise positive pricing sentiment.
• One review (2025-03-11, 1-star) explicitly warns readers to get a second opinion on A-1 Total Service Plumbing recommendations, citing a misdiagnosis and an unnecessary $2,400 repair quote when a $400 hydrojet and simple obstruction removal solved the problem.
• One review (2025-05-10, 2-star) describes being charged nearly $700 for a snake that did not resolve the issue, followed by a $7,000 camera quote and then no response when requesting camera footage — suggesting possible upselling and poor follow-through.
• One review (2024-11-11, 1-star) and one review (2018-07-28, 1-star) cite rude phone/office staff, and one review (2022-08-17, 1-star) describes the owner being rude and late to an estimate appointment — a recurring pattern of customer service issues at the front-end of the business.
• One review (2017-07-17, 1-star) describes a technician breaking faucet handles and then becoming unreachable for follow-up repair — a project completion failure.
• One review (2021-03-03, 1-star) describes incomplete work and a system left without hot water after the technician departed.
• Review dates span from 2011 to 2025. Reviews older than 12 months (pre-June 2024) should be weighted less heavily. The most recent reviews (2025) are mixed, with both strong positives and notable negatives appearing in the same period.

This WW Score carries HIGH data confidence due to the large volume of substantive reviews, but its reliability as a single-entity score is meaningfully reduced by the apparent aggregation of reviews from at least two distinct businesses; prospective customers should verify which specific company and technician they are engaging before relying on this score.

Bay Area Plumbing (Ron) has a strong overall reputation built across more than a decade of reviews, with the vast majority of customers praising his punctuality, responsiveness, communication, and fair pricing. His technical ability is frequently highlighted — particularly his capacity to diagnose problems quickly, solve issues other plumbers could not, and handle a wide variety of jobs from water heaters to sewer lines to full remodels. However, there are 7 negative reviews (ratings of 1–2 stars) that cannot be dismissed: they describe a failed guarantee on a leak repair, an abandoned contracted job costing a general contractor thousands, a no-show with no call, unprofessional behavior on the phone including hanging up on a customer, a toilet installation left non-functional with overcharging, and a flooding emergency where BAP failed to diagnose the cause. These negative reviews meaningfully reduce scores in professionalism and project completion. The score reflects a contractor who performs well in the majority of cases but has a documented pattern of serious failures in a minority of engagements.

• 7 negative reviews (1–2 star ratings) document serious issues: one abandoned contract job requiring a second contractor and lawsuit, one failed leak repair with no refund or follow-through, one toilet installation left non-functional with alleged overcharging and harassment after complaint, one no-show with no notification, one rude phone interaction with inconsistent pricing quoted, one emergency flooding diagnosis failure, and one recurring problem 5 months after original repair.
• 9 reviews contain no text at all (rating only) — these were excluded from dimension scoring as they provide no usable evidence.
• Review span is very wide: oldest reviews date to 2010–2013 and include some of the most negative experiences. Most recent reviews (2024–2025) are predominantly positive, suggesting possible improvement over time, but older negative reviews still reflect documented failures.
• Several reviews are very brief and generic (e.g., 'Excellent.', 'He did a good job', 'Great service, very professional.', 'Thanks!') with no specifics — these were counted for sentiment but given reduced weight in dimension scoring.
• One review references 'Joshua' and another references 'Carlos' as the technician rather than Ron, suggesting other staff have worked jobs — quality consistency across team members cannot be fully assessed.
• Recency note: The most recent 12 months (May 2024 – May 2025) contain approximately 30+ reviews, nearly all positive, which is a favorable signal. However, the negative reviews are spread across multiple years and are not isolated to a single period, indicating recurring rather than resolved issues.

This WW Score is based on a large and diverse review set spanning over a decade and carries HIGH overall confidence, but consumers should weigh the documented negative experiences — particularly the abandoned contract, failed repair guarantee, and non-functional toilet installation — as meaningful risk indicators before hiring.

Josh at A & R Home Services receives consistently positive feedback across all four scored dimensions from a small but coherent set of reviews. Professionalism is the most consistently praised attribute, with all four reviewers noting punctuality, politeness, and responsive communication — including one reviewer who was impressed enough by Josh's outreach alone to want to hire him in the future. Project completion is also well-supported, with multiple reviewers describing a variety of jobs finished thoroughly and to specification, including cleanup after the work. Experience is reflected in the successful handling of diverse tasks ranging from plumbing valve and toilet replacements to drywall repair and cabinet assembly, with results described as high quality. Pricing is mentioned positively in two reviews as reasonable and fair, though the limited mentions mean this score carries lower confidence. Overall, the reviews paint a reliable picture of a capable and professional handyman, though the small sample size limits the statistical weight of these findings.

• Only 4 reviews total — sample size is too small to draw high-confidence conclusions about any dimension.
• All 4 reviews are 5-star ratings with no negative feedback of any kind. While the reviews do contain specific details and varied scenarios, the uniformly perfect ratings warrant mild caution.
• One review (2023-09-25) is based solely on a communication interaction and not on completed work — it was counted for professionalism only and excluded from project completion and experience scoring.
• Two of the four reviews are dated more than 12 months prior to the most recent review (2024-08-10), meaning recency weighting slightly favors the single 2024 review, which is the most detailed and specific.

This WW Score is based on only 4 reviews and should be treated as a promising but preliminary indicator — more reviews are needed before this score can be considered a fully reliable representation of contractor performance.

Jim earns strong marks across all four dimensions, with pricing and technical experience standing out as particular strengths — the vast majority of reviewers praise his fair, transparent, and often surprisingly low rates, and his ability to handle a wide range of trades (plumbing, electrical, carpentry, HVAC, drywall) is consistently highlighted. Professionalism and project completion scores are pulled down meaningfully by a recurring and credible pattern of no-shows and communication failures: at least five separate reviewers (across different years) report Jim failing to show up for scheduled appointments without calling, failing to return calls or texts, or abandoning jobs mid-engagement. Quality-of-work complaints also appear in a small but notable cluster of reviews, including poor caulking, a substandard cement patch, and a disputed walk-in tub installation. These negative signals are credible, specific, and span multiple years, preventing a higher overall score despite the overwhelming volume of positive feedback.

• RECURRING NO-SHOW / GHOST PATTERN: At least 5 reviews (2016-08-10, 2016-09-28, 2017-02-13, 2019-11-29, 2017-10-10) independently describe Jim failing to show up for scheduled appointments, not returning calls or texts, or going silent after initial contact. This is a consistent and credible pattern that materially impacts the professionalism and project completion scores.
• WORKMANSHIP COMPLAINTS: Three reviews (2020-09-07, 2015-09-13, 2015-09-23) describe specific quality failures — poor caulking that molded, a mismatched cement patch, and a disputed walk-in tub installation with alleged licensing and worker's comp concerns. These are specific and detailed, lending them credibility.
• LICENSING CONCERN: One reviewer (2015-09-23) claims Jim's contractor's license had expired and alleges misrepresentation on the license regarding employees. This is unverified but noted as a potential flag.
• REVIEW VOLUME SKEW: The overwhelming majority of reviews are 5-star with very positive language. While most appear genuine due to specific job details, the ratio of positive to negative reviews (approximately 72:7) warrants slight caution. No strong fake review pattern detected — most positive reviews include specific project details.
• RECENCY NOTE: The no-show complaints span from 2016 to 2019, with the most recent dated 2019-11-29. More recent reviews (2020–2024) do not repeat this pattern as prominently, suggesting possible improvement, but the pattern is significant enough to retain in scoring.
• AMENDED REVIEW: One review (2018-01-05, 3-star) appears to have been partially misdirected — the reviewer states it was 'meant for another Jim' but then adds a complaint about a soundproof booth project. Treated as a partial negative signal for project completion only.

This WW Score is based on a large and diverse review set (79 reviews spanning 2015–2024) with HIGH confidence across all dimensions; however, the score should be treated with moderate caution due to a credible and recurring pattern of no-shows and communication failures that appears across multiple independent reviewers and years.
