Do these companies show photos of finished walls?
A website link sits on all 15 wall builders here. A photograph of a finished wall tells you very little, because everything that fails is behind the face. Look for pictures taken mid-build instead: the base trench, the drainage stone going in, the grid rolled out between courses. A company that photographs that stage is proud of the right part.
