With the number of foreclosures in today’s real estate market and the long lengths of time homes stay on the market before selling, many properties must be winterized and de-winterized. Winterization is the process that prepares a home to sit vacant without heat/utilities and with the water turned off. It reduces the risk of the plumbing supply lines freezing and causing damage and/or flooding. Often real estate agents or banks will ask home inspectors to perform this service. For those inspectors who offer winterization and de-winterization services, InterNACHI offers this Winterization/De-Winterization Services Agreement.
