Expectations. I got the windows for which I contracted and installers cleaned up before leaving which I expected. However, attention to details were not complete. When removing the old windows, they didn’t remove the security sensors and resecure them to the new windows. As a result I’ve got to contact the security company and request a service call for which I will get to pay for new sensor contacts. Until then, our security system cannot be armed. Rest assured the window replacements were monetarily significant. I didn’t expect to incur an additional expense as a result of failure to attend to details.
