The verdict in three sentences
In 2026, choose a redesign (CAD 10,000-25,000) if your technical foundation still holds and the problem is mostly visual or editorial; choose a rebuild (CAD 30,000-70,000) if your CMS is over 5 years old, technical debt blocks changes, or performance is unrecoverable. The simple rule: when the cumulative cost of patches exceeds 40% of a rebuild, rebuild. Expect 6 weeks for a redesign versus 14 weeks for a rebuild.
The per-criterion scoring grid
Rather than an intuition debate, score each criterion 0 (favours redesign) to 3 (favours rebuild). A total above 15 out of 24 leans clearly toward rebuilding.
| Criterion | Redesign (0-1) | Rebuild (2-3) | Weight |
|---|---|---|---|
| CMS age | < 3 years | > 5 years | high |
| Technical debt | low, clean code | abandoned plugins | high |
| Performance (Core Web Vitals) | "needs improvement" | persistently "poor" | medium |
| Data structure | reusable | inconsistent | medium |
| New functional needs | minor | major (portal, e-commerce) | high |
| Design | refresh | fully obsolete | low |
| Current SEO | strong, preserve it | already weak | medium |
| Security / maintainability | acceptable | vulnerable | high |
Costs, timelines and break-even
The financial comparison must include the hidden cost of successive redesigns. A "cheap" redesign redone twice in three years often costs more than a single rebuild.
| Scenario | 2026 cost (CAD) | Timeline | SEO risk |
|---|---|---|---|
| Partial redesign (design + content) | 10,000 - 16,000 | 5-7 wks | low |
| Heavy redesign (+ features) | 16,000 - 25,000 | 7-10 wks | moderate |
| Custom rebuild | 30,000 - 70,000 | 12-16 wks | manageable (redirects) |
| A redesign redone 2x in 3 years | 20,000 - 35,000 | cumulative | high |
Simple break-even: if you plan to add major features within 18 months, an immediate rebuild avoids paying twice.

Mini case study
Mark is marketing director at a digital-services SME in Toronto. His site runs on a 2018 CMS with 14 plugins, 3 of them abandoned. Grid score: 17/24 (old CMS, high debt, needs a client portal). A CAD 16,000 redesign would fix the visuals but leave the technical debt. He opts for a rebuild at CAD 42,000 over 14 weeks. Over 3 years he avoids two patch-redesigns estimated at CAD 14,000 each plus a major outage risk. The CAD 26,000 upfront premium is absorbed by maintenance savings and the new lead-generation capacity of the client portal alone.
FAQ
How do I know if my CMS is "too old"? Beyond 5 years, most CMSs accumulate obsolete dependencies and vulnerabilities. If updates regularly break the site, that is a strong rebuild signal.
Can a redesign lose my SEO? Yes, if URLs change without 301 redirects. With a careful migration plan, both redesign and rebuild preserve most of your rankings.
Is a rebuild always more expensive in the end? Not necessarily. If you must add major features, a rebuild avoids stacking redesigns that, combined, often exceed its cost.
How much longer does a rebuild take? Roughly double a redesign: 12-16 weeks versus 5-10. That extra time buys a clean foundation for 4-5 years.
Can I redesign now and rebuild later? Yes, but only if the redesign is genuinely transitional and budgeted as such. Otherwise you pay twice to start over.
