Where do I start, I'm an end unit and they drilled into my mortar into my house wrap. It flooded my basement and they wouldn't clean the water up. Within 48 hours my entire basement was full of black mould. The mould travelled to my neighbours entire basement. I hired a company to test for mould, before the test came back, Monarch emailed me stating they were here and no mould was visible! Guess what, the report came back positive!!!! More to follow, after the battle that continues for almost 9 months now.
