Find Nearby Plumbers In Union City, California

Cal-Tech Plumbing and Travis receive overwhelmingly positive feedback across all four dimensions, with professionalism being the most consistently praised attribute — punctuality, communication, cleanliness, and respectful conduct are mentioned explicitly across dozens of reviews spanning over a decade. Project completion scores are strong, with numerous reviewers describing jobs finished on time, followed through completely, and even callbacks honored; however, one 1-star review alleges an abandoned or retaliatory service action (gas and water shutoff), which tempers the score modestly. Experience and technical knowledge are praised extensively, with reviewers highlighting Travis's deep understanding of plumbing codes, construction, electrical, and problem-solving under difficult conditions. Pricing scores are solid but not exceptional — multiple reviewers note Travis is 'not the cheapest' while simultaneously affirming strong value, and one reviewer noted pricing was roughly half of competitors for a specific job, suggesting inconsistency depending on project type. One negative review regarding responsiveness (no callback) and one serious allegation of unprofessional conduct prevent a higher overall score.

• One 1-star review (2018-06-16) alleges that a person named 'Craig' from Cal-Tech illegally shut off water and gas at a customer's home during a billing dispute, resulting in a restraining order filing. This is a serious allegation. A separate reviewer (2018-07-12) disputes this review's credibility, claiming 'Craig' never worked for the company. The conflicting accounts reduce confidence in this specific incident but the allegation cannot be dismissed.
• One 1-star review (2021-04-25) reports multiple unanswered voicemails with no callback, indicating a potential responsiveness issue that contrasts with the majority of reviews praising quick response times.
• The review corpus spans from 2010 to 2021. The majority of reviews are older than 12 months relative to the most recent review date (2021-04-29), and a significant portion are from 2013–2018. Recency weighting is limited; the most recent reviews (2020–2021) remain positive but the volume of recent reviews is lower than the historical base.
• Several reviews use similar superlative language ('best around,' 'hands down the best,' '100 stars,' '10 stars') which could suggest some degree of enthusiastic but potentially coached phrasing. However, the majority of reviews include specific job details, named crew members, and unique circumstances, which significantly reduces the likelihood of fabrication. No fake review flag is raised, but the pattern is noted.
• The business partner review (2018-07-12) explicitly defends Cal-Tech against a negative review and discloses a 10-year business relationship. While the review contains genuine detail, the conflict-of-interest context should be noted when weighing its credibility.

This WW Score is based on 46 reviews spanning over a decade with strong mention counts across all four dimensions, yielding HIGH confidence overall; however, the presence of two negative reviews — one alleging serious misconduct and one citing unresponsiveness — combined with the age of much of the review data means the score should be treated as a reliable historical indicator rather than a guaranteed reflection of current service quality.

This contractor demonstrates strong professionalism with consistent punctuality, responsiveness, and courteous service across 156 mentions. Project completion is reliable with same-day or next-day service frequently delivered and jobs finished within quoted timeframes across 142 mentions. Technical experience is solid with knowledgeable technicians and quality workmanship noted in 89 reviews. However, pricing emerges as a notable weakness: while many customers accept the cost as fair for emergency service, 28 mentions reveal concerns about high labor rates, inflated unit costs, and aggressive fee structures (including a controversial $159 inspection fee that cannot be waived). Two negative reviews (1-star ratings from 2025-01-10 and 2024-01-06) document warranty disputes and poor callback service, suggesting occasional follow-through failures. The company excels in emergency response but struggles with transparent, competitive pricing.

• PRICING CONCERN: Multiple reviews mention high costs and one detailed 1-star review (2025-01-10) alleges deceptive practices including mandatory inspection fees and inflated unit pricing. Another 1-star review (2024-01-06) documents warranty service refusal and poor callback follow-through.
• DUPLICATE REVIEWS DETECTED: Approximately 60+ reviews appear to be exact or near-exact duplicates (same text, same rating, posted on same or consecutive dates). This pattern suggests either data entry errors or potential review manipulation. Confidence in overall score is reduced by this duplication.
• RECENCY SKEW: Majority of reviews are from 2017-2019 (older than 5 years). Recent reviews (2025) show mixed sentiment with both 5-star praise and serious 1-star complaints, indicating potential service inconsistency or quality decline.
• WARRANTY/CALLBACK FAILURES: Two separate 1-star reviews document refusal to honor warranty claims and poor responsiveness to callback requests, contradicting the otherwise strong professionalism scores.
• PRICE TRANSPARENCY ISSUE: One detailed complaint describes being forced to pay $159 inspection fee to receive a quote, with the company defending high pricing by citing operational costs rather than providing competitive market rates.

This WW Score of 82.1 should be treated with MODERATE-to-HIGH confidence for emergency response and professionalism, but LOW confidence for pricing fairness. The high volume of duplicate reviews and the presence of serious unresolved complaints (warranty disputes, callback failures) in recent months suggest the overall score may overstate current service quality. Customers should expect excellent emergency response and professional technicians but should obtain independent quotes and carefully review warranty terms before committing.

Pop N Go Plumbing earns strong marks across all four dimensions, driven by a large volume of reviews praising Joe and his team's professionalism, communication, punctuality, and technical skill. The professionalism score is particularly well-supported, with dozens of reviewers explicitly citing friendliness, clear explanations, prompt arrival, and courteous service. Experience scores are bolstered by multiple accounts of Pop N Go solving problems that other plumbers could not, including complex drain clogs, pipe repairs, and water heater installations. Pricing is generally viewed favorably — many reviewers note reasonable or fair costs — but two negative reviews cite overcharging or questionable billing practices, which temper the pricing score meaningfully. Project completion is strong overall, though one review explicitly states the problem was not resolved after the visit, and one negative review describes an incomplete job that required a callback, preventing a top-tier score in that dimension.

• DUPLICATE REVIEWS DETECTED: At least 4 reviews appear to be near-identical or exact duplicates posted on different dates (e.g., the 'After dealing with an unprofessional plumbing company' review appears twice; the 'Joe was very knowledgeable and experienced on recently replacing our hot water heater' review appears twice; the 'Joe and his son Michael helped us out last November' review appears twice; the 'Really great service! Mike was our plumber' review appears twice). These duplicates have been counted only once each for scoring purposes.
• BLANK REVIEWS: At least 5 reviews contain no text content — only a 5-star rating. These provide no usable data for dimension scoring and were excluded from dimension analysis.
• NEGATIVE PRICING SIGNAL: One reviewer (2019) paid $264 for a 10-minute toilet unclog and considered it not worth it. Another reviewer (2020) describes being charged an additional $275 for a shutoff valve they disputed causing damage to, raising concerns about billing transparency in isolated cases.
• INCOMPLETE JOB FLAG: One reviewer (2017, rated 2.5 stars) explicitly states 'When they left I thought the problem was solved, but it was not,' indicating at least one instance of incomplete resolution.
• RECENCY NOTE: The majority of reviews are older than 12 months relative to a 2024 analysis date. Only a small number of reviews (2023–2024) are recent. The most recent review is from June 2024. Scores are weighted toward recent reviews where possible, but the bulk of evidence is from 2016–2022.
• FAKE REVIEW RISK — LOW TO MODERATE: While many reviews are generic in praise, a significant number include specific job details, named technicians, and unique circumstances, reducing fake review concern. However, the presence of exact duplicate reviews on different dates is a mild concern and may indicate review manipulation or platform errors.

This WW Score is based on a large volume of reviews (109 total, ~100 with usable data) spanning multiple years, giving it HIGH overall confidence, though the score should be interpreted with moderate caution due to detected duplicate reviews, several blank reviews, two credible negative billing complaints, and the fact that most reviews predate 2023.

Day and Night Plumbing demonstrates strong overall performance across all four dimensions, with particular strength in professionalism (86.5) and solid execution in pricing, project completion, and technical experience. The company benefits from extensive positive feedback spanning multiple years, with technicians consistently praised for punctuality, friendliness, and responsiveness. Pricing is generally perceived as fair and competitive, though a small number of reviews cite higher-than-expected costs for service calls. Project completion is reliable with most jobs finished on time and to customer satisfaction, though two negative reviews from 2017 and 2022 indicate occasional diagnostic errors and property damage concerns. Technical competence is well-documented across diverse plumbing tasks including sewer work, water heater replacement, and drain clearing.

• Two significant negative reviews (1-star ratings from 2022-08-07 and 2017-04-02) report serious issues: incorrect diagnosis, property damage from improper water pressure application, and unprofessional staff behavior. These represent material service failures that warrant caution.
• One additional 1-star review (2017-02-03) cites excessive pricing ($277.31 for tub/sink drain clearing), suggesting potential pricing inconsistency or evening hour surcharges not clearly communicated.
• One 2-star review (2014-03-08) reports negative personality/attitude from technicians, indicating potential interpersonal consistency issues despite good technical work.
• Another 1-star review (2017-04-02) describes incomplete drain clearing that required a second contractor to fully resolve, suggesting occasional quality control gaps.
• Multiple reviews from 2023 and earlier (approximately 40% of dataset) are older than 12 months; recency bias favors more recent 2024-2025 reviews which are uniformly positive.
• Several reviews contain minimal detail (e.g., 'Great service. Fast and on time. Job well done.') and 5 reviews have empty text fields, limiting depth of analysis for those entries.
• No evidence of fake review patterns detected; reviews show varied specific details, named technicians, and realistic problem descriptions across different time periods.

This WW Score of 82.1 is highly reliable, based on 115 usable reviews with strong mention counts across all dimensions (42-87 mentions per dimension). However, the score should be interpreted with awareness that three serious negative reviews (incorrect diagnosis, property damage, excessive pricing) represent material service failures that occurred despite the company's otherwise strong track record. Prospective customers should expect generally excellent service but should verify diagnostic accuracy and obtain clear pricing before work begins, particularly for complex issues.

Brent's Plumbing scores consistently well across all four dimensions based on seven reviews spanning 2011 to 2024. Project completion is the strongest dimension, with every reviewer confirming jobs were finished same-day or promptly, often under difficult conditions such as New Year's Eve and Sundays. Pricing is also a clear strength, with multiple reviewers independently describing fees as reasonable and one noting a Yelp discount, suggesting transparent and fair pricing practices. Professionalism scores slightly lower due to one reviewer describing awkward off-topic conversation and an unusual nickname comment, which introduces a minor but notable concern about client-facing conduct. Experience is well-supported, with reviewers citing code-compliant installations, creative problem-solving, and thorough explanations of work performed. However, the overall confidence in this score is tempered by the small review pool and the significant age of most reviews.

• RECENCY WARNING: Only 1 of 7 reviews is from the past 12 months (2024). Five reviews are more than 8 years old (2011–2016), and one is from 2018. The contractor's current quality and practices cannot be reliably inferred from this data.
• CONDUCT CONCERN: The most recent review (2024) describes the contractor calling the customer 'big bus' multiple times and engaging in off-topic conversation about peanut butter during the job. While the reviewer still rated the work positively, this behavior may reflect unprofessional client interaction and warrants attention.
• SMALL SAMPLE SIZE: Only 7 reviews total. Scores should be interpreted cautiously as a small number of outlier experiences could significantly shift results.
• NO FAKE REVIEW PATTERNS DETECTED: Reviews vary in length, detail, writing style, and date. Specific job types, locations, and personal anecdotes are mentioned. No suspicious uniformity detected.

This WW Score carries moderate overall reliability due to a very small review pool and the fact that the vast majority of reviews are significantly outdated, making it difficult to assess the contractor's current performance with confidence.

Prestige Plumbing Solutions has a strong base of positive reviews praising professionalism, punctuality, shoe-cover etiquette, and communication — particularly from technicians Zac and Robert. Pricing is frequently cited as competitive or better than alternatives, with one standout case where the owner honored a quote despite scope expansion. However, the score is meaningfully pulled down by several credible negative reviews: a no-show with no callback (2013), an unresolved estimate follow-up where a $125 fee was taken and no callback was made (2015), a case where a bathroom sink repair was incomplete and required a second plumber, a late arrival with missing parts (2015), and an overcharge complaint on a follow-up visit. Project completion is the most mixed dimension, with multiple instances of first-visit failures requiring callbacks or outside intervention. The large volume of 'unknown' reviews (8 reviews with no text) and the heavy skew of older reviews (most substantive reviews are from 2011–2015) further limit confidence in current performance.

• 8 reviews contain only the text 'unknown' with no usable content — these were excluded from scoring but counted in total reviews analyzed.
• The first review discloses that the reviewer is a personal friend of the owner ('Berto is a very good friend of mine'), which introduces potential bias and was weighted accordingly.
• The majority of detailed, substantive reviews are from 2011–2015, making them 9–13 years old. Only 4 reviews are from 2018 or later, and only 3 are from 2023–2024. Current performance cannot be reliably inferred from this data.
• There is a credible 1-star review (2015) describing a $125 diagnostic fee taken with no follow-up estimate ever provided — a serious trust and ethics concern.
• There is a credible 1-star review (2013) describing a no-show appointment with no call and no callback when the customer followed up — a direct professionalism failure.
• One review (2015) explicitly states the bathroom sink repair was incomplete and required a second plumber to fix — a clear project completion failure.
• One review (2015) notes the technician arrived 30 minutes late and did not have a standard branded part on hand.
• One review (2015) states 'Overcharged on follow up' with no further detail — flagged as a pricing concern.
• Several 5-star 'unknown' reviews with no text and no detail cannot be used to support any dimension score and may artificially inflate the star average on source platforms.

This WW Score carries moderate-to-high reliability in terms of volume, but significant caution is warranted due to the age of most reviews, multiple credible negative incidents involving no-shows, incomplete work, and a fee-without-service complaint, and the exclusion of 8 content-free 'unknown' reviews that cannot be scored.
