Perhaps the freelancer who built your site has moved on. Perhaps the agency relationship ended and you would rather work directly with someone new. Or a friend built the website using an AI tool and has no interest in maintaining it. None of those situations necessarily means the website is faulty.
If your site is doing its job, I want to keep it that way. The first requirement might be updating services, adding new pages, improving a contact form, changing images or connecting a booking system. Where those changes are straightforward and the access is clear, there may be no reason for a full technical diagnostic.
A more complicated application can be different. If it handles customer accounts, payments, private data or external APIs, even a small-looking change may affect more than one part of the system. In that case I'll explain what needs investigating and why before beginning chargeable work. My AI app maintenance service covers that longer-term stability work once someone has taken responsibility for the build.
I don't treat a change of developer as a reason to tear up working code or redesign a functioning website. I do need a safe way to review and test approved changes before anything goes live.
