When a fire or extended coverage policy settles first party losses on replacement cost, any consequential physical damage caused in making a repair or replacement and not otherwise excluded is part of the loss, and the insured pays nothing beyond the deductible, including no betterment. When replaced items do not match the remaining items in quality, colour or size, the insurer must replace everything in the affected area so that the result looks reasonably uniform, inside and outside, again at no cost beyond the deductible.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
