Web Accessibility Remediation — WAVE-Compliant Digital Experiences

The Business Case for Accessibility

Accessible websites are not a nice-to-have. They are a legal requirement in a growing number of jurisdictions, and they directly impact your bottom line. Over one billion people worldwide live with some form of disability. When your website or application excludes them, you lose customers, risk litigation, and damage your brand.

The European Accessibility Act (EAA), effective June 2025, requires digital products and services sold in the EU to meet accessibility standards. In the United States, ADA lawsuits targeting inaccessible websites have increased year after year. Canada, the UK, Australia, and many other countries enforce similar regulations. The question is no longer whether to invest in accessibility — it is how quickly you can get there.

We help businesses bring their existing web applications into full compliance using the WAVE accessibility evaluation framework, WCAG 2.2 guidelines, and hands-on remediation that goes far beyond automated scanning.

What WAVE Accessibility Evaluation Covers

WAVE (Web Accessibility Evaluation Tool), developed by WebAIM, is one of the most widely trusted accessibility testing frameworks available. It identifies issues that automated tools alone cannot catch and provides detailed, actionable feedback across multiple categories:

Errors — Critical issues that prevent users with disabilities from accessing content. Missing alternative text, empty form labels, broken ARIA references, missing document language, and empty links or buttons.
Contrast Errors — Text and background color combinations that fail WCAG minimum contrast ratios, making content difficult or impossible to read for users with low vision or color blindness.
Alerts — Potential problems that require human review. Redundant title attributes, suspicious link text ("click here"), missing first-level headings, justified text, and possible misuse of structural elements.
Structural Elements — Evaluation of heading hierarchy, landmark regions, lists, tables, and navigation structures to ensure assistive technologies can parse and present content correctly.
ARIA — Assessment of ARIA roles, properties, and states. Incorrect ARIA usage is one of the most common accessibility pitfalls and can actually make interfaces less accessible than having no ARIA at all.

We use WAVE as a core part of our evaluation process, combined with manual testing, screen reader validation, and keyboard-only navigation audits to deliver genuinely accessible applications — not just ones that pass an automated scan.

Our Remediation Process

1. Comprehensive Accessibility Audit

We begin with a full audit of your existing application. Every page, every interactive component, every form, and every media element is evaluated against WCAG 2.2 Level AA criteria using WAVE, axe, Lighthouse, and manual testing with assistive technologies including NVDA, JAWS, and VoiceOver.

You receive a detailed audit report documenting every issue found, its severity, the WCAG success criterion it violates, and exactly where it occurs in your codebase.

2. Prioritized Remediation Plan

Not all accessibility issues carry the same weight. We prioritize based on user impact, legal risk, and implementation complexity. Critical errors that block entire user flows are addressed first. Contrast issues and missing labels come next. Structural improvements and ARIA refinements follow.

We provide a clear timeline, cost estimate, and phased plan so your team knows exactly what to expect at every stage.

3. Code-Level Remediation

Our engineers work directly in your codebase. We fix HTML semantics, add proper ARIA attributes where necessary, correct heading hierarchies, implement skip navigation, ensure keyboard focus management, remediate color contrast, add alt text and captions, fix form labels and error handling, and restructure components for screen reader compatibility.

We do not use overlay widgets or automated "quick fix" tools. These products create a false sense of compliance and often introduce new barriers. We fix the actual source code.

4. Testing and Validation

After remediation, every page is re-tested with WAVE, axe, and Lighthouse to confirm zero errors. We also conduct manual screen reader testing across NVDA (Windows), VoiceOver (macOS/iOS), and TalkBack (Android), plus full keyboard navigation audits.

You receive a final compliance report documenting the resolved state of every previously identified issue.

5. Ongoing Monitoring and Maintenance

Accessibility is not a one-time project. New features, content updates, and design changes can introduce regressions. We offer ongoing monitoring packages that include periodic WAVE scans, regression testing, developer training, and review of new feature deployments before they go live.

What We Fix

Semantic HTML and Document Structure

Correct heading hierarchy (h1 through h6, properly nested)
Landmark regions (header, nav, main, aside, footer)
Meaningful list structures where content is logically grouped
Proper table markup with headers and captions for data tables
Document language declaration

Images and Media

Descriptive alt text for informational images
Empty alt attributes for decorative images
Captions and transcripts for video and audio content
Accessible SVGs with proper roles and labels

Forms and Interactive Elements

Associated labels for every form input
Descriptive error messages tied to specific fields
Accessible custom components (dropdowns, modals, tabs, accordions)
Proper focus management for dynamic content

Keyboard Navigation

Full operability without a mouse
Visible focus indicators on all interactive elements
Logical tab order matching visual layout
Skip navigation links
Focus trapping in modals and dropdown menus

Color and Visual Design

WCAG AA contrast ratios (4.5:1 for normal text, 3:1 for large text)
Information conveyed through color also available through text or icons
High contrast mode compatibility
Reduced motion support for users with vestibular disorders

ARIA Implementation

Correct use of roles, states, and properties
Live regions for dynamically updated content
Accessible names and descriptions for complex widgets
Removal of incorrect or redundant ARIA that harms usability

Industries We Serve

Accessibility applies to every industry, but regulatory pressure and user expectations vary. We have particular experience in:

E-Commerce and Retail — Product listings, checkout flows, payment forms, and mobile shopping experiences
Financial Services — Online banking, insurance portals, investment platforms, and regulatory documentation
Healthcare — Patient portals, appointment booking, telemedicine interfaces, and health information systems
Education — Learning management systems, course content, student portals, and examination platforms
Government and Public Sector — Citizen services, public information portals, and document publishing
SaaS and Technology — Dashboards, admin panels, data visualization, and developer tools
Media and Publishing — News sites, content platforms, podcast players, and video portals

Compliance Standards We Address

WCAG 2.2 Level AA — The international standard for web content accessibility
Section 508 — U.S. federal accessibility requirements for information and communication technology
ADA Title III — Americans with Disabilities Act requirements for places of public accommodation, increasingly applied to websites
European Accessibility Act (EAA) — EU-wide requirements for digital products and services, effective June 2025
EN 301 549 — European standard for ICT accessibility, harmonized with WCAG
AODA — Accessibility for Ontarians with Disabilities Act
DDA — UK Disability Discrimination Act

Technology Stack

We remediate accessibility issues across all major frontend frameworks and content management systems:

React, Next.js, Vue, Angular, Svelte — Component-level ARIA fixes, focus management, keyboard handlers
WordPress, Drupal, Shopify, Magento — Theme-level fixes, plugin accessibility reviews, template remediation
Native Mobile (iOS, Android) — VoiceOver and TalkBack compatibility, accessible touch targets, dynamic type support
Email Templates — Accessible HTML email with proper structure, alt text, and screen reader compatibility

Why Work With Us

No overlay tools — We fix your actual code. Overlay widgets do not achieve genuine compliance and face increasing legal scrutiny.
WAVE expertise — Our team uses WAVE as a primary evaluation framework, supplemented by axe-core, Lighthouse, and manual assistive technology testing.
Developer-first approach — We work in your repository, follow your coding standards, and write clean, maintainable fixes that your team can build on.
Ongoing support — Accessibility is a continuous process. We offer monitoring, training, and pre-launch review services to prevent regressions.
