Find Nearby Plumbers In Riverside, California

NIR Plumbing demonstrates strong professionalism and experience across a large volume of reviews, with consistent praise for punctuality, friendliness, responsiveness, and technical skill from named technicians including Nick, Sergio, Juan, Mike, and Isaac. Project completion scores are high, with multiple reviewers noting jobs finished thoroughly, on time, and with clean workspaces. However, pricing is a significant drag on the overall score — multiple independent negative reviews (1–2 stars) explicitly cite a $350 service call fee as excessive, lack of upfront pricing transparency, and charges perceived as exploitative, including one reviewer charged $700 for a $20 part and another charged $390 for two hose bibs. One negative review also flags a serious conduct concern involving a company vehicle nearly running a customer's wife off the road, which reflects on professionalism. The WW Score of 78.4 reflects a genuinely capable and well-regarded company tempered by a meaningful and recurring pattern of pricing complaints.

• DUPLICATE REVIEWS DETECTED: Approximately 30–35 reviews appear to be exact duplicates posted on the same date with identical text (e.g., 'Good Service.', 'Thanks Nic. Always reliable and prompt.', 'Can't say enough about their quality work...', 'Fast service and very thorough', 'NIR is the best plumbing company...', and many others). This is a strong indicator of review manipulation or a platform sync error. Duplicate reviews were deduplicated before scoring.
• FAKE REVIEW RISK — MODERATE: Several short, generic reviews ('Good Service.', 'Always Great Service.', 'Great work and great service.') with no specifics appear across multiple dates. Combined with the duplicate pattern, confidence in the raw review pool is reduced.
• PRICING COMPLAINTS — RECURRING PATTERN: At least 5 independent negative reviews (1–2 stars) explicitly cite excessive pricing, lack of upfront quotes, or feeling taken advantage of. This is not isolated and represents a systemic concern that meaningfully lowers the pricing dimension score.
• CONDUCT FLAG: One reviewer (1 star, April 2025) alleges a company vehicle nearly ran their wife off the road. While unverifiable, this is a serious behavioral concern that was factored into the professionalism score.
• RECENCY NOTE: The majority of reviews are from 2024–2025 and are therefore recent and given full weight. A smaller number of reviews date back to 2014–2020 and were given slightly reduced weight, though they were largely consistent in tone with recent reviews.
• BLANK REVIEWS: Several reviews contained no text (only a 5-star rating). These were excluded from dimension scoring as they provide no usable data per scoring rules.

This WW Score is based on a large deduplicated review set with HIGH confidence across all four dimensions; however, the score should be interpreted with caution due to detected duplicate reviews suggesting possible manipulation, a recurring and credible pattern of pricing complaints from multiple independent reviewers, and one serious conduct allegation — prospective customers should weigh the strong service quality feedback against the consistent pricing transparency concerns before engaging this contractor.

America's Irrigation & Landscaping earns strong marks for technical knowledge and fair pricing, with dozens of reviewers explicitly praising Manuel's expertise, honest estimates, and reasonable rates. Professionalism scores are solid but meaningfully dragged down by a recurring and serious pattern: multiple reviewers across different years report that the company came out for estimates, collected measurements, and then never delivered a written quote or followed up — a pattern spanning 2020 through 2022. Project completion is the most penalized dimension because beyond the lost-estimate complaints, one reviewer reported that post-service rewiring caused controller programming loss and that Manuel went silent after payment was collected, directly contradicting the responsiveness praised elsewhere. The experience dimension remains the strongest, with highly specific and credible praise for problem-solving, irrigation knowledge, and quality of finished work across many independent reviews.

• RECURRING FOLLOW-UP FAILURE PATTERN: At least 5 independent reviewers (2020-07-08, 2020-11-10, 2021-01-26, 2021-06-30, 2022-08-08) report that the company visited for estimates, took measurements or spent significant time, and then never delivered a written quote or responded further. This is a systemic operational issue, not isolated incidents.
• POST-PAYMENT UNRESPONSIVENESS: One reviewer (2024-09-06) explicitly states Manuel was prompt before payment but ignored multiple follow-up texts after payment when a potential issue caused by the company's rewiring work emerged. This is a significant trust and accountability concern.
• VAGUE REVIEWS NOTED: Two reviews (2019-12-05, both rated 5 stars, posted the same day with nearly identical phrasing — 'These guys were amazing, fast and very honest') are highly suspicious for being duplicate or coordinated fake reviews. Confidence in those two reviews is reduced to zero and they were excluded from scoring.
• RECENCY NOTE: The most recent reviews (2024) are limited in number. The bulk of reviews are from 2019-2022. Behavior patterns — particularly the estimate follow-up failures — appear across multiple years, suggesting they may reflect ongoing operational weaknesses rather than isolated past issues.
• ONE-STAR AMBIGUOUS REVIEW: The 1-star review from 2021-08-30 references a photo and owner response but provides no scorable detail. It was excluded from dimension scoring but noted as a signal of a dissatisfied customer.

This WW Score is based on a large and diverse review set with HIGH confidence across all four dimensions, but the score should be interpreted cautiously given a documented and repeated pattern of estimate abandonment and at least one credible post-payment unresponsiveness complaint — issues that are likely underrepresented in the overall star ratings.

Ameri-Cal Repipe & Plumbing receives strong praise across most dimensions, with numerous reviewers highlighting timely project completion, competitive pricing, and skilled workmanship on complex full-house repipe jobs. Professionalism scores are tempered by three notably negative reviews citing rude field staff, poor cleanup practices that endangered children with asthma, and a dismissive response to legitimate post-job concerns about wall patching and hazardous water line placement. Project completion scores are similarly pulled down by the cleanup failure review and the 'paint ready' miscommunication complaint, which represent meaningful breakdowns in follow-through and honest communication. Pricing and experience dimensions are generally positive, with multiple reviewers noting competitive quotes, no surprise costs, and technically sound work using quality materials like Uponor PEX. Overall, the company performs well on large repipe jobs but has documented inconsistencies in cleanup standards, communication honesty, and field staff conduct.

• DUPLICATE REVIEW DETECTED: The Lake Arrowhead repipe review (Rating 5.0, Date 2020-11-03) appears verbatim a second time with no date. This is a confirmed duplicate and was counted only once for scoring purposes.
• FAKE REVIEW RISK — MODERATE: Several reviews are extremely brief and generic (e.g., 'These guys treated me really well and did an excellent job. I would recommend them to anyone.' and 'They repiped my home 4 years ago and did an amazing job. I highly recommend this company.') with no specifics, dates, or verifiable details. These may be low-effort or inauthentic reviews and were weighted conservatively.
• MISSING DATES: The majority of reviews have no date attached. Only one review has a confirmed date (2024-02-07) and one has a date of 2020-11-03. It is impossible to assess recency for most reviews, which limits the ability to determine whether quality has improved or declined over time.
• NEGATIVE PATTERN — CLEANUP FAILURES: At least two separate reviews (1-star condo dust/debris complaint and 3-star paint-ready complaint) cite post-job cleanup and finish quality as significant failures. This is a recurring operational weakness, not an isolated incident.
• NEGATIVE PATTERN — STAFF CONDUCT: Two 1-star reviews specifically call out poor staff behavior ('train your field staff in some manners' and 'not knowledgeable about their products'). One 5-star review also explicitly warns against the company's 'business guy.' This suggests inconsistency in personnel quality.
• RECENCY CAVEAT: With only one review confirmed within the past 12 months (February 2024), the bulk of this score is built on undated reviews of unknown age. The WW Score should be treated as a historical average rather than a current performance indicator.

This WW Score is based on a reasonable volume of reviews (22 total, 21 usable) with HIGH mention counts across all four dimensions, but its reliability is meaningfully reduced by the near-total absence of review dates, the presence of at least one confirmed duplicate review, several suspiciously generic 5-star reviews, and a pattern of recurring negative experiences around cleanup and staff conduct that suggests systemic rather than isolated issues.

This plumbing service demonstrates strong professionalism with consistent punctuality, courteous communication, and respectful behavior across the majority of reviews. Pricing is generally perceived as fair and competitive, with transparent quotes and no hidden charges frequently mentioned. Project completion shows solid execution with most jobs finished on time and to specification, though some warranty-related delays and incomplete work issues appear in older reviews. Technical expertise is evident with skilled diagnostics and quality workmanship. However, the dataset contains significant historical negative reviews (2013-2016) concentrated around home warranty claims, suggesting past operational challenges that may have been addressed. Recent reviews (2021-2025) are overwhelmingly positive, indicating substantial improvement.

• TEMPORAL BIAS DETECTED: Approximately 40% of reviews are from 2013-2016 with predominantly negative ratings (1-star) related to home warranty claims. These older reviews heavily criticize communication, scheduling, and claim handling. Recent reviews (2021-2025) are overwhelmingly 5-star positive, suggesting either significant company improvement or potential review manipulation.
• FAKE REVIEW PATTERN SUSPECTED: Multiple reviews from June 2023 and June 2010 contain nearly identical phrasing ('Great service!', 'Amazing service!', 'Professional and reliable') with minimal detail. Several reviews lack substantive content (empty text fields with 5-star ratings). This pattern warrants caution.
• INCONSISTENT COMPANY IDENTITY: Reviews reference multiple business names (Professional Plumbing Services, Emergency Plumbing Services, EPS, Edo's Plumbing, Best Plumbing & Electric) and multiple named technicians (Angel, Jose, Edmond, Greg, Gage, Jay, Mike, Lupe, etc.), suggesting either multiple locations, rebranding, or data aggregation from different companies.
• NEGATIVE REVIEW CONCENTRATION: Home warranty-related reviews (2013-2016) show systemic issues: no-shows, poor communication, claim denials, rude staff, and scheduling problems. These represent legitimate service failures distinct from recent positive reviews.
• RECENCY CONCERN: 65% of reviews are from 2021 onward. If company was recently acquired or restructured, older reviews may not reflect current operations. Score heavily weighted toward recent positive data.

This WW Score of 78.2 should be interpreted with MODERATE-TO-HIGH caution due to significant temporal clustering and suspected review manipulation in the dataset. Recent reviews (2021-2025) strongly support the score, but the dramatic reversal from 2013-2016 negative reviews raises questions about data integrity and whether all reviews reference the same company/management. The score reflects current service quality based on recent evidence, but historical warranty claim issues suggest past operational problems. Recommend verifying current ownership and management before relying on this score for high-stakes decisions.

Thompson Family Plumbing demonstrates strong professionalism (87.5) with consistent praise for punctuality, courteous technicians, and responsive communication across 156 reviews. Technical expertise and workmanship are highly rated (86.0) with 142 mentions of knowledgeable, skilled technicians. Project completion is solid (84.5) with 118 reviews confirming timely, thorough work. However, pricing is a significant weakness (62.0) with 48 explicit complaints about excessive costs, overcharges, and quotes substantially above market rates. The company's WW Score of 78.2 reflects strong execution and professionalism undermined by persistent pricing concerns that damage customer satisfaction and trust.

• PRICING PATTERN: 48 reviews explicitly mention high/excessive pricing. Multiple customers report quotes 2-3x higher than competitors (e.g., $7,000 vs. $1,321 for water heater; $3,591 vs. $1,321; $1,500 for simple sink install; $375/hour labor). This is the most consistent negative theme.
• INCONSISTENT SERVICE QUALITY: Several reviews report failed installations requiring callbacks (water heater installation fiasco, faucet leaks after installation, backflow issues requiring multiple visits). While company generally stands behind work, initial quality is sometimes questionable.
• DIAGNOSTIC FEES & UPSELLING: Multiple complaints about $85 diagnostic fees, high-pressure sales tactics, and unnecessary work recommendations. Pattern suggests aggressive sales approach.
• SCHEDULING RELIABILITY: 3-4 reviews report missed appointments, rescheduling without notice, or technicians not showing up as promised (May 2024 review, May 2025 review).
• FAKE REVIEW RISK - MODERATE: Approximately 40-50 reviews are extremely generic ("Great job!", "Thank you", "Awesome experience") with no specific details, appearing in clusters on same dates (e.g., 2025-06-02, 2025-06-05, 2025-03-11). However, these are balanced by highly detailed, credible reviews with specific technician names and problem descriptions. Overall fake review risk is LIMITED rather than HIGH because substantive negative reviews with specific pricing details are also present and appear authentic.
• RECENCY NOTE: Majority of reviews are from past 12 months (2025, 2024, 2023), with strong recent activity. Data is current and reliable.

This WW Score of 78.2 is highly reliable due to 261 reviews with consistent patterns across all dimensions. The strong professionalism and experience ratings are well-supported by 156+ detailed mentions. However, the pricing weakness (62.0) is equally well-documented with 48 explicit complaints citing specific overcharges. Customers should expect professional, skilled service but should obtain multiple quotes and expect to pay premium prices—potentially 50-200% above market rates for comparable work.

Guardian Plumbers demonstrates strong professionalism and technical expertise, with consistently positive feedback on technician friendliness, punctuality, and problem-solving ability. Project completion is generally reliable with same-day service frequently mentioned. However, pricing emerges as a significant weakness, with numerous complaints about quotes being 2-3x higher than competitors, aggressive upselling tactics, and charges for estimates. While many customers praise fair pricing, a substantial minority report feeling overcharged or misled on costs. The company excels in communication and responsiveness but struggles with pricing transparency and value perception.

• PRICING PATTERN: 68 reviews explicitly mention pricing concerns. Approximately 25-30 reviews contain complaints about high quotes, overcharging, or aggressive upselling. This is the most consistent negative theme across the dataset.
• UPSELLING ALLEGATIONS: Multiple reviews (at least 12) describe pressure to purchase expensive filtration systems ($5,000-$7,000+), water heater replacements, or unnecessary work. Some customers report feeling manipulated or condescended to during sales pitches.
• QUOTE DISCREPANCIES: At least 8 reviews describe situations where Guardian's quote was 2-3x higher than competitors for identical work, or where work quoted at high cost was completed by other plumbers for 10-20% of the price.
• FOLLOW-UP FAILURES: Multiple reviews (at least 5) describe promised follow-up work, debris removal, or warranty service that was never completed or was delayed indefinitely.
• QUALITY CONTROL ISSUES: Several reviews (at least 4) describe incomplete work, miscommunication between technicians, or damage to property (burned holes in tub surrounds, chipped tubs, poor drywall repairs) that was not adequately addressed.
• NO SHOW/LATE ARRIVALS: At least 3 reviews describe missed appointments or significant delays despite confirmation calls.
• POTENTIAL FAKE REVIEWS: Approximately 15-20 reviews are blank (5-star rating with no text), and several reviews contain nearly identical phrasing (e.g., 'A bit pricey, but good quality work' appears twice verbatim; 'William did a great job unclogging our sink. Guardian was most responsive' appears twice verbatim; 'Guardian sent out a technician named Mike' appears twice verbatim). This suggests possible review manipulation.
• RECENCY BIAS: Most recent reviews (2025) are overwhelmingly positive with minimal pricing complaints, while 2023-2024 reviews contain more balanced criticism. This pattern warrants caution regarding review authenticity.
• MISDIAGNOSIS CLAIMS: At least 5 reviews describe situations where Guardian diagnosed problems incorrectly or recommended unnecessary work that other plumbers identified as unnecessary.

This WW Score of 78.2 should be interpreted with MODERATE-TO-HIGH caution: while Guardian demonstrates genuine strengths in professionalism, responsiveness, and technical skill (supported by 89+ mentions of expertise), the pricing dimension is heavily contested and represents a material risk factor. The company appears to operate a two-tier service model—delivering excellent work but at premium prices with aggressive upselling tactics. Customers should obtain multiple quotes before engaging and carefully scrutinize any recommendations for expensive add-on systems. The presence of duplicate reviews and blank 5-star entries suggests some review inflation, which slightly reduces confidence in the overall score. For emergency/same-day service, Guardian is highly reliable; for planned work, competitive bidding is strongly advised.
