This west coast of Canada house was built in 1991 and the exterior was redone about 8 years ago. This west-facing wall gets the afternoon sun. Weather here is mild – mid 20s/70s in summer, a couple of degrees around zero in winter.
Cracks have existed on this wall but not on any other walls of the house, for the past 5-6 years. A week or so ago some cracks opened up big enough to slide a pencil into, and last night during strong wind a large section fell off. Here’s another photo of the area: https://i.imgur.com/eAEIYPD.jpg
Is this to be expected after 8-10 years or is there a fault in how it was done that needs addressing by the company that did it? They’ll be coming out this week to have a look and I’d like to have an idea of what my position on the matter should be.
