They are not plumbers per se, but they do have a number of the technical skills that can help you repair a busted pipe. They are also the answer to good risk management practice long before the plumber or insurance assessor decides to show up. What you have here is a quick responding emergency response team that can just as easily see to repair broken pipe issues and help you cut loss and damage costs. They are, in essence, your much needed emergency response team.
They are not magicians either. Like you, they cannot foresee what the unpredictable weather is going to do. But they have decided to brace themselves for all eventualities. This is their calling. Another call will be the distress call. That is something you will need to make the next time you and your home or business fall into the soup. The response to your call is almost immediate. That is one of their specialties.
While other technicians may be loath to travel through inclement weather, yes, that is quite correct; you can make your distress call in the heat of the moment when the storm seems to show no sign of abating. They may not be able to do a full cleanup operation at this point in time but at least their sterling work can go some way in minimizing the potential loss and damage to you. They clear away all knocked down structures.
And they move away the debris as quickly as possible. They are not plumbers, nor are they those troublesome insurance loss assessors. They are certainly not electricians. What they are though is your specialist storm damage remediation team, a team that you can rely on in your darkest hour.
