They came to install new windows in my apartment and the job took almost 6 hours - mind you, I live in an apt in PB (2bed/1bath). The workers were friendly enough, but I (and my neighbors I'm sure) could have done without the blasting music at 8am - although I did enjoy one guy's off-pitch singing!
The one thing that was irritating was their very un-thorough cleaning job. There were pieces of glass left on my bedroom floor, their equipment was soo dusty and dirty, I think it left more dirt than sucked away and they were not very delicate with the maneuvering... very little regard for white walls or furniture; now that's just rude!
The company was selected by my landlord - so I imagine she was more focused on price, which is why I gave it a 'good' rating though I can't be 100% positive.
Most irritating was that they took almost an hour longer than they had initially promised and yet I found them hanging out outside while just a single team member did any work! Plus, I just think it's rude to smoke right outside an open window - I mean they unistalled the windows so they're just smoking directly into my living room at this point! Finally, they finish the job and I am waiting in my car to pull out of my driveway, but they are hanging around talking to eachother while blocking my in my own parking space (tandem spaces).
However, they did get the job done!
Pros : Got the job done, windows look pretty good!
Cons : Took a long time, coulda been more thorough, considerate, cleaner.
