Why remediation matters

Overlays don't work. Courts reject them. Users hate them. An overlay widget injects JavaScript that tries to patch your site as it loads — it cannot rewrite structural code problems, and courts have consistently declined to accept an installed overlay as proof of compliance. Real accessibility compliance requires fixing the underlying code. Zylyn's engineers implement fixes directly or work alongside your developers to close every finding at the source. Every fix is validated with assistive technology before it's marked resolved.

  • HTML structure and ARIA
  • Keyboard navigation and focus management
  • Colour contrast and visual design
  • Form labels and error handling
  • Captions and media accessibility
  • PDF and document accessibility
  • Mobile app accessibility (iOS and Android)

Frequently asked questions

Common questions about remediation services.

The process of fixing accessibility barriers identified in an audit — at the code level, not with a surface overlay. Real remediation changes the underlying HTML, CSS, and JavaScript so assistive technologies can actually use your site.

No. Overlays inject JavaScript that tries to patch your site as it loads. They cannot rewrite structural code problems, and courts have consistently declined to accept an installed overlay as proof of compliance. Remediation fixes the source. An overlay on top of properly remediated code is a usability convenience — never a substitute.

Yes, for Managed Remediation engagements. Zylyn engineers implement fixes directly or pair with your developers. For teams that prefer to do their own fixes, we provide code-ready guidance for every issue.

Anything in scope: web pages, web apps, mobile apps (iOS and Android), PDFs, Word documents, and multimedia captions. The scope is agreed at the start based on your audit findings.

Timelines depend on the number and complexity of issues. Simple remediations run in days. Large-scale projects are scoped during the discovery call. We sequence work by severity so the highest-risk issues are resolved first.

Every fix is validated against WCAG with assistive technology testing before it's marked resolved. We update the findings report to reflect confirmed fixes and retest the full scope after major remediation work.
