The ruin that fires cause is another particularly challenging type of property damage for commercial property to sustain. If not controlled and extinguished quickly, the entire building and all the assets inside are at risk. An engulfing fire can therefore be devastating. To successfully file a fire damage claim, you should photograph damaged items and the building itself. And keeping as much of this evidence as you can without discarding it is important, however, just in case your insurance provider requests to see it in person.
