Ceiling Pro is here in the UK now and you shouldn't get pestered anymore as all the UK areas have now been sold. Unfortunately, that it the way the Americans do things, they are heavily into telesales as phone calls are as cheap as chips.
Processes have since moved on too, though cleaning is always going to be a dirty job, odd as it sounds.
If anyone has an issue with acoustic or vinyl ceiling tiles, post a question up here or contact us directly, we'd be happy to try and help or offer advice.
