The depressing office mystery

A tenant once complained their office felt depressing. That was not the maintenance ticket I expected

I'm a property manager. Nothing was broken and just gloomy. My first thought was how do I fix a mood? Maybe it’s their problem because their jobs are boring… But I stopped by to look

The windows are so dirty it was like a gray filter over the whole building. The grime built up so gradually that no one had noticed. The tenant joked that Nashville must have turned cloudier

So I knew we needed window washing. But honestly? I have no idea who to call... There are dozens of companies out there, and every website looks the same. I don't know who's reliable or fair-priced
