We just purchased our new home and had Kaiser come in and install the additional garage lift for our second garage door. Ramon - the installer arrived on time and installed the garage door successfully. He also had the necessary parts for the options we thought of at the very last moment.
Beside the excellent service with the installation, Ramon returned in short order with the long screws needed to attach the wall controller and the light bulbs for the new lift.
I highly recommend Kaiser as a service provider and will use them to service my garage doors in the future.
