Modernize Legacy Website — Without Re-launching Your Site
Modern, fast, conversion-tuned — without losing your SEO
What you're seeing
You're on jQuery + PHP + table-based layouts and every change takes a week.
Our approach
We modernise incrementally with the strangler-fig pattern — route by route, with no big-bang launch and no SEO disruption.
Signs it is time for this
- The design looks dated and your team avoids sharing the link
- Mobile visitors zoom, scroll sideways or bounce
- Conversion is flat despite steady traffic
- Every content change needs an engineer
What we plan around
- 01A modern design system instead of one-off page styling
- 02A 301 map that protects existing SEO equity
- 03Conversion-first layouts backed by analytics, not opinion
- 04A CMS your marketing team will actually use
What you get

Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Design system and high-fidelity Figma

From brief to shipped fix
A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.
Diagnose
A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.
Scoped plan & quote
You get a written plan to modernize Legacy Website, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.
Ship the fix
We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.
Verify & hand off
We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.
Why teams hand this task to Krapton
Senior engineers only
Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.
Root cause, not a patch
We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.
Your repo, your standards
Every change lands as a pull request you review, on your repository, following your existing review process.
NDA on day one
Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.
Fixed quote up front
You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.
Proof, where it applies
Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.
Three ways to engage
No retainer required. Pick the model that matches the work — pricing for this task starts from $4,500, with a fixed quote before anything starts.

Modernize Legacy Website — your questions, answered
How much does it cost to modernize Legacy Website?
Pricing starts from $4,500 and depends on the scope we find during the diagnostic. You get a fixed, written quote before any work begins — most engagements like this run 4–8 weeks.
How long does it take to modernize Legacy Website?
Typically 4–8 weeks for a focused engagement. After a short diagnostic we commit to a firm timeline so you know exactly what to expect.
Will you work directly on our existing codebase?
Yes. We work on your GitHub, GitLab or Bitbucket, ship every change as a pull request you review, and follow your code-review standards — not ours.
What exactly will I have at the end?
Concrete, documented outcomes — Design system and high-fidelity Figma, Pixel-perfect responsive implementation, 301-mapped migration that preserves SEO equity, and more. No black-box agency report.
How quickly can you start, and do you sign an NDA?
For a focused task like this we can usually start within 24–48 hours of the brief. We sign an NDA on day one, before we look at any code — yours or ours.
Will the redesign hurt my existing SEO?
No — protecting your SEO equity is part of the scope. We 301-map every URL, preserve metadata and structure, and verify parity post-launch so rankings carry over rather than reset.
