How our guides are researched, written, updated and corrected, and how we keep money away from the numbers.
Prices, rules and rankings are set by our methodology, not by advertisers or listed businesses. No company can pay to change a price range, a rule summary or its place in the organic list.
We use official sources for rules (state licensing boards, attorneys general, building departments) For costs we compare at least three published sources, such as national cost guides (HomeGuide, Angi, HomeAdvisor) and supplier list prices, and name them on the page.
Every page shows when it was last checked. License and rebate rules are reviewed every three months and other facts once a year, or sooner when a law or price changes.
When we find or are told about an error, we check it against the source, correct it and update the date on the page. Significant corrections are noted on the page.
Our guides are general information. Cost figures are estimates, not quotes, and state rule summaries are not legal advice; confirm with the official source before you sign a contract.
If we ever publish content paid for by a manufacturer or supplier, it will be labeled “Sponsored” and its links marked rel=”sponsored”. See our advertiser disclosure.
| Source type | What it gives us | Where you see it |
|---|---|---|
| Published cost guides | National low, typical and high ranges (for example HomeGuide, Angi and HomeAdvisor) | The range table on every cost guide |
| Supplier list prices | Material costs for concrete, shingles, pavers, lumber and fixtures | The material share of a range and the calculator inputs |
| State licensing boards | The board name, licence lookup and renewal rules for a trade | Each state licence page |
| Manufacturer documentation | Specifications and efficiency figures for equipment | Replacement and efficiency pages |
| Our own calculators | Worked examples derived from the same prices | Calculator pages and the price index |
| Content | Update cycle |
|---|---|
| Price ranges | Re-checked twice a year, or sooner when a supplier list changes sharply |
| Calculators | Re-run when the prices behind them change, and when a bug is reported |
| State licence rules | Checked against the board site; updated when the board changes a rule or a link |
| Corrections | On confirmation, with the change noted on the page |
Software tools may help draft and check pages, but every published number is compared with the sources listed above, and a person edits and approves the page before it goes live. If a number cannot be traced to a source, it is not published. Guides are not generated and published without review.
Advertisers and listed businesses cannot buy a place in a price table, a calculator result, an editorial ranking or a licence summary. Paid placements are confined to the directory and are labelled. The full split is in our advertiser disclosure.

Email admin@localservicehq.com with the page URL and the source that contradicts it. If the source is stronger, the page is updated and the change is noted. If neither can be confirmed, the claim is removed.
