The verdict in three sentences
Endlessly patching an old site is often more expensive than rebuilding it: technical debt turns every fix into a project. The 2026 rule: when annual maintenance exceeds 40% of the cost of a new site, a redesign (10,000 to 16,000 EUR) becomes more profitable over 3 years. The signal isn't aesthetic, it's financial and technical: debt, incompatibilities, collapsing performance.
The technical signals that force a redesign
A director paying repeated patches must read objective signals, not trust "it still works". Here are the tipping-point indicators in 2026.
| Signal | Concrete symptom | Verdict |
|---|---|---|
| Technical debt | End-of-life CMS/framework, abandoned plugins | Plan a redesign |
| Incompatibilities | Breaks on every PHP/browser update | Redesign priority |
| Performance | LCP > 4 s, mobile score < 50 | Redesign advised |
| Security | Flaws unfixable without a rewrite | Redesign urgent |
| Maintenance cost | > 40% of a new site's price/year | Redesign profitable |
| Non-compliance | GDPR/accessibility impossible to retrofit | Redesign + compliance |
When two of these signals are red, maintenance becomes a bottomless pit: you're paying to delay the inevitable.
The quantified decision tree: repair or rebuild
The decision models simply. Compare projected annual maintenance over 3 years against the cost of a redesign amortised over the same period.
| Scenario | Maintenance/yr | 3-yr cost | Redesign 3 yr (13,000 EUR + 2,000/yr) | Decision |
|---|---|---|---|---|
| Healthy site | 1,500 EUR | 4,500 EUR | 19,000 EUR | Maintain |
| Ageing site | 3,000 EUR | 9,000 EUR | 19,000 EUR | Maintain, monitor |
| Indebted site | 5,000 EUR | 15,000 EUR | 19,000 EUR | Prepare redesign |
| Critical site | 7,000 EUR | 21,000 EUR | 19,000 EUR | Redesign profitable |
| Site + business gains | 5,000 EUR | 15,000 EUR + lost revenue | 19,000 EUR | Redesign obvious |
The pure calculation underestimates one key factor: a new site is not just a replacement, it generates more (better conversion, SEO, mobile). Factor in that business gain and the tipping threshold often drops below 40%.
Mini case study
Elodie, director of a 25-person consulting firm in Toronto, pays 3,200 EUR/year patching a 2016 site (obsolete CMS, LCP at 5 s, not responsive). Over 3 years that's 9,600 EUR — for a site that stays slow and converts poorly. Redesign quote: 13,500 EUR + 2,000 EUR/year maintenance = 19,500 EUR over 3 years. The raw gap is 9,900 EUR in favour of maintenance. But the redesign projects +30% contact requests (the current site loses mobile visitors, 60% of traffic): at 40 leads/year worth an average 4,000 EUR of signed work, +30% represents +48,000 EUR of potential revenue over 3 years. The redesign wins: it doesn't replace a cost, it unlocks revenue.

FAQ
When should you rebuild a site rather than maintain it?
The 2026 rule: when annual maintenance exceeds 40% of a new site's price, or when two technical signals (debt, incompatibilities, security) are red. Beyond that, you're paying to delay the inevitable.
How much does a site redesign cost in Toronto in 2026?
Expect 10,000 to 16,000 EUR for a professional brochure/corporate site, excluding advanced features. Add ~2,000 EUR/year of maintenance on the new site.
Does a redesign lose acquired SEO?
Not if done well: 301 redirect plan, keeping useful structure, content migration. A poorly managed redesign can tank SEO; a serious provider protects and improves rankings.
Can you redesign in phases to spread the budget?
Yes: redesign the design and technical core first, then modules (blog, client area) later. You can also start with an audit at 800-1,500 EUR to objectify the decision before committing the 13,000 EUR.
How long does a redesign take?
Expect 6 to 12 weeks depending on scope: framing and design 2-4 weeks, development 3-6 weeks, testing and migration 1-2 weeks. A critical site plans a tested cutover to avoid any downtime.
