Terrible office service. Terrible. I have a big "view" window that was installed by this company in the 80s.
Trying to get repairs (new handles, realignment etc) done on it has been torturous the last 4 years.
Excessive phone tag with the office with prolonged call backs from their office.
The service guys rarely have what they need to fix your windows onsite, which means another couple of years of office tango to get a quote, appointment and another service appointment.
I will be recommending to the building that they change preferred window maintainers as the service of this company has seriously declined in the last five years.
