Frequently asked questions

Do you repair intercom systems you didn’t install?

Yes. We work on many existing intercom systems and can advise the best fix or replacement route if parts are obsolete.

Can you fix the door release as well?

Yes—if the intercom is triggering a lock or door entry release, we can diagnose the full chain from button to lock operation.

Can you repair block intercoms with multiple flats?

Yes. We can test shared components (panel, power, trunk wiring) and individual units to isolate faults efficiently.
