Home Weatherization

The typical home is said to have enough air leaks that’s equivalent to having a window open year-round. If you’re like the typical homeowner, that means you’re basically wasting 20% or more of the energy you pay to heat and cool your home. Needless to say, weatherizing your home can add tremendous energy and cost savings.In this first of three series of articles regarding weatherizing your home, we will dive in a little deeper and discuss why you need it, where to look for air leaks, and how to figure out if you need it.
It Goes Beyond the Savings
Yes, by weatherizing your home you will feel more comfortable during the hottest and coldest of months, and save energy and money in the process. However, home weatherization goes further, beyond the idea of protecting the envelop of the house to prevent loss of energy from the unwanted exchange of inside and outside air.Here’s what you may not know: Preventing the unwanted circulation or infiltration of air also reduces humidity, dust and pollen; eliminates pests and noise; and even prevents the growth and spread of mold that may eventually compromise the integrity of a building support structure. In essence, you can say it’s an investment in your health and your home.

Sealing reduces humidity, dust and pollen
Insulating eliminates pests and noise
Caulking prevents growth and spread of mold

Where to Look for It
Before you know what to look for, you need to know where to look. You may already know gaps and cracks in window and door frames are one of the biggest culprits of drafts, but the infiltration actually occurs throughout the house in and around these common areas:
Air Leaks from the Outside

Cable, TV and phone wiring
Chimney
Door and window frames
Electronic outlets on exterior walls (inside the house)
Gas service entraces
Kitchen and dryer exhaust fans
Mail chutes
Outdoor faucet
Wall air conditioning units

Air Leaks from the Inside

Attic stairs / hatch
Duct register
Dropped soffit
Plumbing vent stack
Recessed lights

Other Problem Areas

Attic space
Basements
Crawl space
Floor
Laundry room
Space between foundation and walls
Space between chimney and siding
Roof

How to Look for It
The easiest way to get started is to call your local utility company to ask if they offer either a home audit / inspection rebate program (in exchange for the job of weatherizing your home) and/or cover a percentage of the cost of weatherization. Some states, such as Georgia, even have weatherization assistance programs where qualifying families can receive free home inspections and weatherization installations.If you refer to or have to do it yourself, have no fear, there are simple expensive gadget-free tests you can conduct to see what’s going on in your home. Below is a summary of the self-test methods as well as the other options you have:
