When your facility is down, you need a company that will respond quickly to your emergency. You can depend on Alterman to get there fast-24 hours a day, seven days a week-even if your emergency happens at 3 o'clock in the morning, on Sunday, or on a holiday.  Emergency service is provided after normal business hours through Automated Voice Messaging.  Just call our daytime number at 210-496-6888.  After you have left a message, a service manager is immediately paged to respond to your call.  Whatever it takes, we'll be there promptly with experienced electricians and fully equipped vehicles.
