Water intrusion alarm systems may provide you peace of mind in helping to detect a leak or flood and may prevent serious water damage from occurring. These alarms only work, however, if they’re heard in time to locate the source of the water and turn it off before serious damage happens. Damage may still occur if the water is thoroughly extracted and your property is not dried out thoroughly by a professional restoration company.
