MAPLEWOOD, N.J. (CBS 2) — As temperatures start to drop, homeowners will have to winterize as CBS 2’s Derricke Dennis reports.

Triza Quito of Maplewood, N.J. lives in a house so drafty that she put plastic over her windows.

“Um, even though the heat is up, you can feel the cold drafts coming in,” Quito said.

But a spray of insulation is exactly what she needs, said Tom Wolfe, a home improvement expert.

“This is an insulation filler, that when you spray it in those gaps, it expands and fills all the cracks,” Wolfe said. “We’re having air come through here, and we want to fill this in.”

Within seconds, the gap is filled and air can’t get in.

“Fifty percent of your energy bill is due to heating and cooling being released from your house,” Wolfe said.

Testing the insulation spray is in the store is one thing, but it’s easier to understand when seen on an actual home.

Homeowners can also us a hair drier to smooth out that plastic over home windows. It’s a film, sold as a kid, to stop cold drafts.

And the average window, believe it or not, saves $17 a year, when done this way.

A programmable thermostat is another quick fix that’ll save homeowners money. You can set the time to turn for when your heat goes on and off.

When you’re at work, you don’t need to have the heat on when you’re not there, but a half hour before you come home, you set up the heat so that it comes on.

But experts say the biggest loss of heat may be at your front door. A double draft stop can be the solution.

“It’s one of the easiest things we have, and for $7, it does wonders. It seems easy. It is,” Wolfe said.

If you place the draft stop, filled with foam tubing under the door and closing it, you can notice the difference immediately—a solution for Quito, who needs all the help she can get.

“Yeah, I definitely do, I’m from California,” Quito said.

Another recommendation is if you have a central air furnace, change the filter. Changing the filter will help it run more efficiently, saving money on your energy bill.
