Editorial standards
The short answer
- Every technical claim traces to a published standard, a manufacturer's technical instruction, or established shop practice that a working technician would recognise.
- We do not publish invented statistics. Where a figure is a typical field range rather than measured data, the page says so in plain language.
- Legal and insurance content describes structure and category, and always points to the state or the policy document as the authority, because those change.
- Pages carry a visible last updated date, and material changes are logged publicly on the corrections page.
- Nothing here is sponsored, and no article placement, ranking or recommendation is for sale.
This page describes how the content here is built and what it refuses to do. It is written to be checked, not admired: everything below is a commitment you can hold a specific page against.
What counts as a source
Windshield work is governed by a small set of documents and a large body of established practice. Technical claims here trace back to one of the following, and where a claim is contested we say so rather than picking a side quietly.
| Source type | What it governs | How we use it |
|---|---|---|
| Federal motor vehicle safety standards, principally FMVSS 205 (glazing materials) and FMVSS 212 (windshield mounting) | What a windshield must be and how it must be retained | Named where relevant, described in plain language, never quoted as if we had verified specific paragraph text for your vehicle. |
| ANSI/SAE Z26.1 | Safety glazing material specification referenced by federal rules | Used to explain the DOT marking and glazing categories. |
| Auto glass industry standards published through the Auto Glass Safety Council, including the replacement standard and the repair standard commonly known as ROLAGS | Correct replacement procedure and the limits of what should be repaired | Used for repairability limits and installation practice, described rather than reproduced. The map of which document governs which part of the job is on the standards page. |
| Adhesive and glass manufacturer technical instructions | Safe drive away time, primer use, bead geometry, cure behaviour | Described as a class. We always tell readers that only their shop's specific adhesive chart governs their car. |
| Vehicle manufacturer service information | Calibration procedure, static or dynamic, tolerances and preconditions | Described generically, because procedures are model specific and change with software revisions. |
| State vehicle codes, DMV and state police publications, state insurance departments | Obstruction rules, inspection programs, glass coverage regulation | Summarised at the level of structure with a link to the state's official portal, never reproduced as if current. |
| Established shop practice | Prices, timings, what shops will and will not attempt | Presented explicitly as typical ranges and common practice, never dressed up as a study. |
What we will not publish
- Invented statistics. No made up percentages, no fabricated survey results, no numbers attributed to organisations that did not publish them. This is the single most common failure in this niche, and the reason a widely repeated claim about the share of a vehicle's structural strength carried by the windshield does not appear on this site as fact: we could not trace it to a primary source.
- Fabricated experience. No invented anecdotes, no claimed job counts, no manufactured credentials. Expertise here is demonstrated by getting the technical detail right, not by asserting it.
- Brand rankings we have not earned. We describe how repair kits and glass tiers differ as categories. We do not publish "best kit" lists based on nothing.
- Scare copy. Damaged glass carries real risks and they are explained precisely, in terms of the three mechanisms that matter in is a cracked windshield dangerous. We do not inflate them to push a replacement.
- Fake specificity. No statute numbers, fine amounts or state specific legal thresholds we have not verified. Category level accuracy with a pointer to the authority beats confident detail that is wrong.
Review and updating
Each page carries a last reviewed date. A page is revisited when any of the following happens: an industry standard is revised, a state changes its inspection program or glass insurance regulation, prices drift outside the published bands, a reader challenge shows an error, or twelve months pass without a review. Price bands across the whole site are checked for internal consistency together, so that a figure quoted on a cost page matches the estimator and the state pages.
Consistency between pages is checked mechanically as well as by reading. The price bands, the repairability thresholds and the facts about the governing standards are held in a single internal reference, and an automated check runs over every page before publication to catch a figure or a claim that has drifted away from it. That is how a number quoted on a cost page, in the estimator and on a state page stays the same number.
When a change is material, meaning it would alter a reader's decision, it is recorded on the corrections page with the date and what changed. Typo fixes and rewording are not logged.
How uncertainty is handled
Three phrases appear throughout the site and each means something specific. "Typical range" means a band drawn from common practice, not a measurement. "Commonly reported" means a widely stated rule that a reader must verify against their own state or policy, used mostly for insurance regimes and inspection programs. "Verify with" followed by a source means we are confident about the category and not about the current detail, which is the honest position for anything that a legislature can change.
Where technicians genuinely disagree, such as whether to repair damage in the driver's primary viewing area or how far a long crack repair can be pushed, the page presents both positions and the reasoning behind each, then gives a decision rule the reader can apply to their own situation.
Independence
No advertiser sees content before it publishes, no article carries paid placement, and no shop, insurer or manufacturer has input into a recommendation. There is no affiliate revenue on this site, no lead sales and no shop directory. Details of the funding model are on the about page, and how the price ranges are built is documented in the methodology.
Frequently asked questions
Why are there no author bylines?
Pages are published under the site name and stand on what they contain: the standards named, the thresholds given, the arithmetic shown. Every factual claim is checkable, which is a stronger guarantee than a name at the top of the page.
Why do you use ranges instead of exact prices?
Because exact prices do not exist nationally. Glass part cost, labor rate, calibration requirement and part scarcity vary enormously. A range that is honest about its width is more useful than a precise number that is wrong everywhere.
How often are pages updated?
Price bands are reviewed at least annually, and any page is updated as soon as a standard, a procedure or a state program changes in a way that affects the advice. The date at the bottom of each page reflects its last review.
