How it works

  1. Drop-off / intake: we log symptoms and priority (data-critical or not).
  2. Diagnostics: we confirm the cause and outline options.
  3. Quote: you approve the work before we proceed.
  4. Fix + test: we verify stability and hand it back with notes.
No on-site at the moment. Remote support available for many issues.

FAQ

Stuff people ask every week.

Do you work on Macs?

No — Apple is proprietary and we don’t service Macs.

Do you repair phones or iPads?

No — we do not service phones or iPads.

Can you recover my files?

Sometimes. If the drive is failing, the best move is to stop using it and bring it in. We’ll attempt non-destructive recovery first.

Do you do house calls or on-site business support?

No on-site at the moment. Remote repairs are available for many problems.
