Absolutely not. There is no such thing as a 'small' property loss. Property damage can occur from leaking air conditioning pans, shower pans, supply hoses, broken water pipes, a high wind storm, or hail. These losses can be as frustrating to deal with as a major property loss. Insurance companies are notorious for allowing inadequate repairs and underpaying 'small' claims such as these, leaving the property owner to foot the bill for the repairs.
Another aspect to consider is any potential hidden or unforeseen damage as well as residual damage that will be sustained to your property to complete the repairs. Although a leaking shower pan may not appear to be a severe loss, once the repairs are initiated you may open the proverbial can of worms.
Having a professional who can foresee the potential issues from his or her visual inspection at onset of the file and the knowledge to properly document any additional repairs is paramount to a satisfactory settlement.
