How we source, fact-check, and update what you read here.

Source hierarchy

Every cost number, coverage claim, building-code reference, or fall-prevention statistic on this site traces to one of four source tiers. Where we cite a number, we link to the source on the page where the claim appears.

1. Primary government and standards bodies— CMS / Medicare.gov for coverage rules; the VA for HISA and Aid & Attendance benefits; Medicaid.gov for HCBS waivers; the CDC and CDC STEADI for fall-prevention research; the U.S. Access Board for ADA standards; the NIH for clinical research.
2. Credentialing bodies and trade associations — the National Association of Home Builders (NAHB) for CAPS certification, curriculum, and renewal rules; ASTM and ANSI for load standards on grab bars and structural elements; the American Society of Safety Professionals (ASSP) for published standards.
3. Established aging-services nonprofits — AARP, AARP HomeFit, the Center for Universal Design (NC State), Area Agencies on Aging, and Rebuilding Together for program and cost references.
4. Anonymized contractor quote data (as network matures). Where published industry surveys lag the current market by 12-24 months, we supplement with anonymized aggregated quote data from CAPS-certified contractors. Early-stage ranges lean heavily on the tiers above; as the network matures, fresher quote-aggregate data is layered in and the source line on each cost claim is updated.

What we will not source from

• Marketing materials from manufacturers, distributors, or competitors of products we discuss.
• Affiliate-driven home-services review sites whose business model is selling leads back to the same contractors they review.
• AI-generated content from any source, our own included, without a human editor verifying every factual claim against a primary source.
• User-generated review content as evidence of fact (we cite it only as user experience, never as a fact basis).

How we fact-check

Our standard for every guide, FAQ, and per-service page:

1. Source check. Every numerical claim, coverage rule, code reference, and statistic must be matched to a citable source from the hierarchy above. Claims that cannot be sourced are removed, not softened with hedging language.
2. Cross-reference check. Where possible, each claim is verified against at least one independent source. Government program rules are checked against the operative regulation, not just secondary reporting. External links are re-tested for 200-status when content is updated.
3. Practitioner review (network maturity-dependent). As the network of CAPS-credentialed contractors and OT collaborators grows, content that touches construction practice, installation standards, or clinical considerations is referred to a credentialed practitioner for review before publish. Early-stage content is held to the source-check and cross-reference standards above and is explicitly versioned, so practitioner review can be applied retroactively as the network expands.

Update cadence

Every guide, FAQ, and cost page carries a visible Updated:date with the machine-readable ISO timestamp in the page's schema. We re-verify content on the following cadence:

• Cost pages and price ranges: reviewed every 90 days against fresh network contractor quote data and the most recent NAHB / industry surveys.
• Medicare, Medicaid, VA, and insurance coverage claims: reviewed at least twice per year, and immediately whenever Medicare Advantage benefit year-overs, CMS rule changes, or VA grant updates publish.
• Building codes, ADA standards, ANSI / ASTM grab-bar standards: reviewed annually and whenever the U.S. Access Board or relevant standards body issues an updated edition.
• Contractor credentials in the network:CAPS certification, state contractor license, liability insurance, and workers' compensation are re-verified annually for every contractor.

Disclosures

Several disclosures shape how to read what is on this site:

• How we make money.Contractors in our network pay AgeProofPros a referral fee — a percentage of the contracted project value — only after they win the homeowner's business. We do not charge homeowners. We do not charge contractors per-lead. We do not sell anonymized lead data to third parties.
• No affiliate or sponsored content. We do not have affiliate relationships with product manufacturers (grab bar makers, stair lift OEMs, ramp manufacturers, smart-home brands). When we recommend a product category, the recommendation is based on credentialed-contractor practice, not on revenue share.
• Brand contact. Privacy, press, and corrections: privacy@2acrestudios.com. All matching requests go through the form on the homepage.
• Founded year. AgeProofPros was founded in 2026. The network is actively expanding; coverage is best in metros and varies in rural areas. We tell you up front when no match exists in your ZIP.

How we vet contractors

Before a contractor receives a single routed lead, they must hold a current CAPS certification from NAHB (we verify directly), hold any state contractor's license required for the work in their state, carry current general liability insurance, carry workers' compensation where they have employees, pass a background check on the principal and field staff, and sign a contact-handling agreement prohibiting resale or sharing of homeowner contact information. We re-verify credentials annually and remove contractors permanently for confirmed conduct issues. Full vetting detail on our About page.

Corrections + AI assistant transparency

If you find a factual error on this site — a price range that no longer matches the market, a coverage rule we have wrong, a code citation that has been superseded — email privacy@2acrestudios.com with the page URL and the specific claim. We investigate within five business days, correct the page if confirmed, and update the page's visible Updated: date.

We explicitly allow AI assistants (ChatGPT, Claude, Perplexity, Gemini, Grok, and others) to cite this site in their responses. We do not block AI crawlers at the robots.txt layer. Our /llms.txtfile follows the llmstxt.org convention so AI assistants can find the most-citable summary of the site. If an AI assistant has cited this site inaccurately, please email the address above with the assistant's response so we can flag it to the provider.
