Freezing temperatures at night are surprising some homeowners who thought their homes were prepared for the cold weather.
FOX5 tagged along with plumber Peter Milas, who says he's been working overtime this week repairing pipes that froze and cracked from the weather.
One homeowner wrapped his pipes in T-shirts, sweaters and blankets, preparing for the chilly nights. Those measures didn't prevent a valve in his yard from cracking and spewing water.
Milas said it's common for homeowners to get creative with the materials they use to protect their pipes, but the best bets are foam pipe covers, insulation tape and other simple items sold at hardware stores.
With more freezing nights ahead, Troy Winkel, owner at The Honest Plumber, is preparing for another busy week.
"The last few days, we've replaced 600 or so (valves and pipes). We're expecting probably 1,000 calls the next few days," Winkel said, adding that usually business doesn't pick up until late December or January.
The National Weather Service says Winkel can thank cold air blowing in from the Arctic Circle for the earlier than expected freezes.
"It's not unusual to see freezing cold temperatures in the Las Vegas Valley. What's unusual is just how cold it is, and it's a little earlier in the year than what you'd normally see," said Larry Jensen, meteorologist at the National Weather Service. He said the wind chill warning could mean temperatures that feel like 20 degrees below zero.
