Water lines that run inside your walls are a common culprit of water damage. All it takes is a little pin hole and major damage can occur. Copper pipes are very susceptible to collect mineral deposits that corrode and create a weak spot in the line. the next thing you know you wake up to water spots in a ceiling or warped hard wood floors.
Of course all this damage can be repaired by a reputable water damage contractor. The trick is finding a contractor with a good reputation that is honest and will do good work. Look for a contractor with many years of experience. It is common for contractors to pop up out of nowhere thinking there is big money handling insurance claims. Many of these types are in it for the quick buck and don’t have what it takes to stay in business for the long haul. They either do not know how to handle the wide variety of water damage that can occur, or they are not honest or both. Either way, they are out of business quickly.
Also look for certifications from organizations like IICRC. Being certified by the Institute of Inspection Inspection Cleaning and Restoration Certification is at least a step in the right direction towards being reputable.
Lastly, ask your friends and business colleagues who they’ve used in the past, don’t just pull a contractor off the internet or out of the phone book. If a friend has had a good experience with a contractor in the past it is more likely you’ll have a good experience too.
