Find Nearby Plumbers In Antioch, California

This aggregated review set covers multiple businesses operating under the 'American Plumbing' name across different regions, which significantly complicates scoring. The majority of reviews are strongly positive, praising responsive technicians, professional conduct, and quality workmanship — with many named employees (Seth, Josh, Matt, Charlie, Felix, Luis, Zeke, and others) receiving repeated commendation. However, a substantial minority of negative reviews — roughly 15-20% of substantive reviews — describe serious issues including rude staff, no-shows, billing disputes, price gouging, incomplete work, and failed inspections, which meaningfully drag down all four dimensions. Pricing is the weakest dimension, with multiple credible complaints about bait-and-switch quotes, unexplained charges, and prices significantly above competitors, though many other reviewers found pricing fair or even below-market. Project completion scores moderately well overall but is penalized by recurring complaints about jobs left unfinished, callbacks not honored, and work failing inspection.

• MULTI-ENTITY CONCERN: Reviews appear to span multiple distinct businesses operating under the 'American Plumbing' name across different U.S. regions (California, Florida, Texas, Louisiana, Ohio, etc.). Scores reflect an aggregate that may not represent any single business accurately.
• FAKE REVIEW CLUSTER DETECTED: A cluster of 1-star reviews dated 2022-06-07 with no review text (approximately 8-10 blank 1-star reviews) and several with near-identical short phrases ('Unprofessional', 'Very unprofessional', 'Very unprofessional and disrespectful') posted on the same date strongly suggests a coordinated negative review attack. These were noted but their impact was moderated given the pattern.
• BLANK REVIEWS EXCLUDED FROM SCORING: Approximately 25-30 reviews contained no text and only a star rating. These were excluded from dimension scoring as they provide no usable evidence per scoring rules.
• RECENCY NOTE: Reviews span from approximately 2006 to June 2025. The most recent 12 months (mid-2024 to mid-2025) are heavily weighted and show a predominantly positive trend, though the detailed negative review from June 2025 regarding permit failures and unprofessional conduct is significant.
• REPEATED REVIEW DETECTED: The review praising Matt and Richard of American Plumbing Laguna Beach appears to be posted twice with slightly different dates (2025-04-10 and 2025-04-07). Only counted once.
• PRICING COMPLAINTS ARE CREDIBLE AND SPECIFIC: Multiple negative pricing reviews include specific dollar amounts, named employees, and detailed circumstances, lending them high credibility. These are not generic complaints and meaningfully reduce the pricing score.
• NO-SHOW AND SCHEDULING FAILURES: Multiple independent reviews across different years describe missed appointments without notification, which is a recurring operational pattern that reduces the professionalism and project completion scores.

This WW Score carries HIGH data confidence due to the large review volume, but its reliability as a guide to any single business is LIMITED because the reviews demonstrably cover multiple distinct companies sharing the 'American Plumbing' name; prospective customers should seek reviews specific to their local branch before making a hiring decision.

Richie's Plumbing scores well on professionalism and project completion, with numerous reviewers praising punctuality, courteous behavior, cleanliness, and thorough follow-through on jobs. Experience scores are solid, with multiple reviewers noting correct diagnoses where other plumbers had failed and competent handling of complex or old plumbing systems. However, pricing is a meaningful drag on the overall score: three separate reviewers across different time periods explicitly complained about feeling overcharged, citing high visit fees relative to minimal work performed, and one reviewer alleged shoddy workmanship (quick-fit connections instead of soldered copper) on a pressurized line. The pricing complaints are specific and credible, preventing a higher score in that dimension despite the majority of reviewers finding prices reasonable.

• Three reviews (1-star: 2019, 2-star: 2016, 1-star: 2014) contain specific, credible complaints about overcharging and one alleges poor workmanship — these are not generic and meaningfully lower the pricing and experience scores.
• One review (2014, 1-star) explicitly alleges defective installation: copper pipe joined with quick-fit connectors instead of soldering on a pressurized line, causing leaks. This is a serious workmanship concern and was factored into the experience score.
• Most reviews are older than 1 year relative to the most recent review date (2024-08-26). The majority of reviews date from 2013–2021, with only one review from the past 12 months. Recency weighting was applied — the single recent review (2024) is positive and was given slightly elevated weight, but the overall dataset skews older.
• No fake review patterns detected. Reviews vary in length, detail, writing style, and rating, and include specific names of plumbers (Richie, Matt, Dave, Johnny) and specific job descriptions. Confidence in authenticity is high.
• The 2020 review references 20+ years of use, suggesting long-term customer loyalty, but this review lacks detail on specific recent interactions and was treated as lower-evidence for individual dimension scoring.

This WW Score is based on 18 reviews spanning approximately 11 years with strong dimension coverage across all four categories, making it moderately reliable overall, though the heavy skew toward older reviews (most pre-2021) means current service quality may differ from what this score reflects.

Fred demonstrates strong technical expertise and professionalism across multiple plumbing disciplines, with consistent praise for knowledge, attention to detail, and honest work. Pricing is notably competitive, with several reviews highlighting favorable quotes compared to competitors. However, project completion shows a significant weakness: one review reports a complete failure to return a call after one week, and several positive reviews mention delays in callback response (2-3 days), which undermines reliability despite eventual quality work. The WW Score of 82.1 reflects strong execution when work begins, but responsiveness and follow-through gaps prevent a higher rating.

• RECENCY CONCERN: 7 of 9 reviews are older than 8 years (2011-2016), with only 2 reviews from 2018 or later. This limits confidence in current service quality and responsiveness standards.
• RESPONSIVENESS PATTERN: Multiple reviews mention delayed callbacks (1 week no response, 2-3 day delays), suggesting chronic communication/availability issues despite eventual quality work.
• REVIEW COMPOSITION: All 9 reviews are either 5-star or 1-star with no middle ratings. The single 1-star review is a stark contrast (no callback after 1 week) versus glowing 5-star reviews, suggesting polarized customer experiences.
• POTENTIAL SURVIVORSHIP BIAS: Dissatisfied customers may not leave reviews; the 1-star review is notable precisely because it breaks the pattern of overwhelming praise.

This score should be treated with caution due to significant data age (most reviews 8+ years old) and a clear responsiveness problem evidenced by callback delays and one complete non-response. While technical quality and pricing appear genuinely strong, current service reliability cannot be confidently assessed from this dataset.

Sergio's business demonstrates strong performance across all measured dimensions, with particular strength in experience and pricing. Professionalism scores are solid, supported by multiple mentions of responsiveness, punctuality, and helpful attitude. Project completion is consistently praised with timely work and follow-through on warranty issues. However, one recent negative review (2018) citing non-responsiveness creates a significant counterweight to the predominantly positive feedback. The overall score reflects this mixed signal: strong execution balanced against a credibility concern about communication consistency.

• SUSPICIOUS REVIEW PATTERN: The first submission appears to be a meta-review that cites multiple HomeGuide reviews verbatim (Russ H., Adwoa, Antonio, Ken, Ed, Tony F., Rafael, Alberto N., Janet G.). This looks like copied content rather than an original customer experience, reducing its authenticity value.
• RECENCY CONCERN: Most reviews are from 2019-2021 (3-5 years old). Only one negative review from 2018 is older. Limited recent data (past 12 months) to assess current performance.
• CREDIBILITY CONFLICT: One 1-star review explicitly states 'owner doesn't bother responding to messages,' which directly contradicts multiple claims of responsiveness in other reviews. This suggests either inconsistent service or a potential service recovery failure.
• SAMPLE SIZE: Only 4 reviews total is a very small dataset. Confidence in the overall score is inherently limited.

This WW Score should be treated with caution due to small sample size (4 reviews), age of most data (3-5 years), and a direct contradiction between positive and negative reviews regarding responsiveness. The score reflects strong historical performance but cannot reliably predict current service quality without more recent feedback.

Class A Plumbing demonstrates solid technical competence and fair pricing across multiple reviews, with experienced technicians (Edwin, Carlos, Joe) delivering quality workmanship and completing jobs as promised. However, professionalism is significantly undermined by serious scheduling and communication failures, including a no-show appointment with no prior notification and a truck breakdown that required rescheduling. While three reviews praise punctuality and politeness, one damaging review documents a 2-hour delay with poor communication and false assurances, creating inconsistency in service reliability.

• Significant recency bias: Two reviews are from 2014-2015 (8-10 years old), one from 2016 (8 years old), and only one from 2024. Historical reviews may not reflect current operations.
• Professionalism scores are pulled down by one severe negative incident (1-star review from 2014) involving no-show and communication failure, balanced against three positive reviews praising politeness and punctuality. This creates high variance.
• Small sample size (4 reviews) limits confidence in overall score. Recommend collecting additional recent reviews before making high-stakes decisions.

This WW Score should be treated with caution due to the small sample size (4 reviews) and heavy reliance on older data; only one recent review (2024) is available to assess current service standards, and the significant gap between positive and negative professionalism experiences suggests operational inconsistency that warrants further investigation.

All three reviews speak positively about professionalism and communication, with one reviewer specifically noting the crew finished ahead of schedule and another highlighting that the inspector was already familiar with and approved of Bayside Trenchless's work. Pricing was mentioned favorably in two reviews, with one reviewer noting a competitive and itemized estimate and another describing the company as the most affordable among several bids. Project completion is well-supported across all three reviews, with no abandoned work and at least one instance of absorbing additional out-of-scope costs without extra billing. Experience is supported by two reviews, including a technically detailed account of a challenging 300-foot sewer replacement on a steep grade that passed all inspections. The overall score is promising but must be treated cautiously given the very small sample size of only three reviews.

• Only 3 reviews analyzed — sample size is too small to draw reliable conclusions about consistent performance.
• All three reviews are 5-star ratings with no negative feedback; while the reviews contain specific details that reduce fake review suspicion, the uniformly perfect ratings warrant caution.
• No reviews older than 12 months were present, which is a positive recency signal but also limits historical performance data.
• No negative or mixed reviews exist in this dataset — it is unknown whether this reflects genuine excellence or a non-representative sample.

This WW Score is based on only 3 reviews and should be considered a preliminary indicator only — significantly more reviews are needed before this score can be trusted as a reliable measure of contractor performance.
