I just received a Newletter from ServiceMaster Restoration by Kast Construction with this great information.  

Frigid Temperatures Burst Water Pipes

The winter months bring colder weather, and with it an increased chance of a common and costly problem for your clients—bursting water pipes. Keep in mind pipes of any material can burst, including PVC, plastic, iron and lead.

To prevent pipe damage during severe cold, instruct your clients to insulate their pipes. Or, if their pipes are uninsulated, let water flow through (even if only a drip or trickle). Doing so will ensure the water won’t have the opportunity to freeze and pipes should survive until temperatures warm above freezing. 

If their pipes do burst, we can help your clients with:

• Water damage restoration
• Drying, dehumidification and water extraction
• Document drying and recovery
• Mold remediation
• Carpet, rug and upholstery cleaning

Our technicians know the effects of water damage on a wide variety of structural surfaces and are experts at both damage mitigation and reducing over-all claim severity. So if you do get a call about a burst pipe, let us get your policy holder’s life back to normal quickly and help you keep costs down and renewals up.

Call 812-944-5094 to reach us 24 hours a day, 7 days a week, 365 days a year.
