Because we don’t guess—we diagnose, explain, and solve.
When your computer’s acting up and you’re not even sure what’s causing the issue, Zoo Computer Repairs is your ideal go-to. We specialise in making the complicated simple, even if all you know is that “something’s not right.” Here’s what makes us stand out from the rest
We Think Like Engineers, Not Salespeople
We’re not here to upsell or convince you to buy a new computer—we’re here to fix the one you’ve got. Our approach is logic-driven, using real data and diagnostics rather than assumptions or unnecessary part replacements
Deep-Level Troubleshooting, Not Surface-Level Fixes
Where others might stop at basic virus scans or a system reset, we go further. We test components individually, analyse system logs, and even check the motherboard and BIOS health if necessary. Whether it’s a failing hard drive, corrupt system file, or something more obscure, we find it
Clear Explanations – No Geek Speak
We take the time to explain the problem in everyday language. You’ll understand what’s wrong, what needs fixing, and why—no confusing tech jargon or vague answers.
No-Fix, No-Fee Option Available
We offer a “no-fix, no-fee” policy on eligible diagnostics, so you won’t pay unless we can help. It’s our way of guaranteeing value for money.
Honest Diagnostics, No Unnecessary Repairs
We don’t charge for unnecessary services. If your system is fine, we’ll tell you. If it needs a simple software tune-up, we won’t pretend you need new hardware
We Come to You (or Connect Remotely)
You don’t need to dismantle your computer or lug it to a shop. We’ll visit your home or office—or connect securely online if that’s more convenient
