How Wise Workman uses data
Wise Workman is a data-driven marketplace that helps homeowners find reliable, trustworthy plumbing professionals. Our platform is built on the principle that contractor rankings should reflect real service quality — not advertising spend, paid placements, or self-reported credentials.
To achieve this, we aggregate publicly available review data from major home services platforms, apply AI-driven analysis to extract meaningful signals, and compute a proprietary Wise Workman (WW) Score for each listed contractor. This page explains exactly how that process works, what data we hold, and what rights you have.
Review data
Publicly available reviews from major home services platforms, aggregated and analyzed for quality signals.
AI analysis
Each review set is processed by our AI engine to extract dimension scores, mention counts, and sentiment signals.
Homeowner data
Contact details provided by homeowners when requesting quotes, stored securely and never sold.
Privacy first
We do not sell, rent, or share personal data with third parties for advertising or marketing purposes.
Review aggregation and sourcing
Wise Workman aggregates publicly available contractor reviews from leading home services platforms. These reviews are written by homeowners and made publicly accessible by those platforms for the purpose of informing consumers about service quality. We do not modify, fabricate, or selectively filter reviews — our system ingests the full available dataset for each contractor and processes it in its entirety.

HomeAdvisorSource credibility weighting
Not all review platforms apply the same level of verification to their review ecosystems. Our system applies a credibility weighting to each source, reflecting the platform's known verification standards and historical reliability. Reviews from more tightly verified platforms carry proportionally more weight in our scoring calculations.
Recency weighting
Service quality changes over time. A contractor who performed exceptionally three years ago may have improved or declined since. Our system applies exponential recency decay — reviews from the past 12 months carry full weight, while older reviews contribute progressively less to the final score. This ensures the WW Score reflects current performance, not historical reputation alone.
Transparency commitment: Every WW Score on our platform includes a "score last updated" timestamp and a detailed narrative explaining what drove the score, how many reviews were analyzed, and any data quality flags identified during processing.
The Wise Workman Score explained
The WW Score is a composite metric calculated across four service dimensions. It is not a simple average of star ratings. It is a confidence-adjusted, evidence-weighted score that reflects both what customers said and how much evidence exists to support each dimension.
The four scoring dimensions
| Dimension | Weight | What it measures |
|---|---|---|
| Project Completion | 35% | Whether jobs were finished completely, on time, with follow-through on callbacks and commitments. |
| Professionalism | 30% | Punctuality, communication quality, attitude, appearance, and responsiveness to the customer. |
| Experience | 20% | Technical skill, quality of workmanship, diagnostic ability, and problem-solving capability. |
| Price Friendly | 15% | Value for money, transparency of pricing, fair quotes, and absence of hidden or unexpected charges. |
How the score is calculated
For each dimension, our AI engine reads the full review set and extracts two values: a sentiment score (0–100) based on what customers explicitly said, and a mention count reflecting how many reviews actually discussed that dimension. A dimension score is only assigned when there is explicit evidence — the absence of complaints does not default to a perfect score.
The final WW Score is calculated as a confidence-weighted average across all dimensions with available data. Dimensions with few mentions are automatically discounted in proportion to their evidential weight. This prevents sparse or unverified data from inflating the overall score.
Key principle: A WW Score of 90% based on 5 reviews is treated very differently from a WW Score of 90% based on 150 reviews. The score itself may look the same, but our confidence system and ranking algorithm ensure the better-evidenced company ranks appropriately higher in directory listings.
Fake review detection
Our AI engine actively screens for patterns consistent with inauthentic reviews — including repetitive language, identical phrasing across multiple submissions, clustering of reviews on identical dates, uniformly perfect ratings across large datasets, and other anomalies. When suspicious patterns are detected, they are flagged in the contractor's score narrative and the affected reviews are down-weighted or excluded from scoring calculations.
The confidence system
Every WW Score is accompanied by a confidence level that tells you how much evidential weight sits behind the number. A score with LIMITED confidence is mathematically valid but based on few reviews — it should be treated as an early signal, not a definitive assessment. A score with HIGH confidence reflects extensive, well-distributed review data across all four dimensions.
| Confidence level | What it means | Typical review count |
|---|---|---|
| HIGH | All dimensions are well-covered with extensive mention counts. Score is highly reliable. | 20+ reviews with broad coverage |
| MODERATE | Most dimensions have sufficient data. Score is reliable with minor caveats noted. | 8–20 reviews |
| LIMITED | Some dimensions have sparse data. Score is directionally useful but treat with caution. | 3–7 reviews |
| NO DATA | Insufficient reviews to calculate a reliable score. Company is listed but not ranked. | Fewer than 3 reviews |
Confidence levels are not displayed as technical labels to end users. Instead, they silently influence where a company appears in directory rankings. A contractor with a HIGH confidence score of 80% will rank above a contractor with a LIMITED confidence score of 88%, because the evidence behind the lower score is stronger and more reliable.
Data about listed contractors
Contractor profiles on Wise Workman are compiled from publicly available business information and review data. We do not require contractors to register or submit information to appear on our platform — listings are generated from publicly accessible sources.
What contractor data we hold
- Business name, location, and service categories
- Publicly available contact information
- Aggregated review data sourced from public platforms
- AI-computed WW Score, dimension scores, mention counts, and narrative analysis
- Licensing and insurance status where publicly available
- Service tags derived from review content and platform categorization
Score disputes and corrections
Contractors who believe their WW Score contains inaccurate information — such as reviews that do not belong to their business, incorrectly attributed data, or factual errors in their profile — may contact us to request a review. We are committed to maintaining accurate and fair representations of every contractor listed on our platform.
Score updates
WW Scores are recalculated periodically as new review data becomes available. Each score displays a "last updated" timestamp so users understand the currency of the data they are viewing. Scores are not static — a contractor's ranking can improve or decline as their review landscape evolves.
