Once you conduct your blower door test, it's time to find the leaks.
Here are some tips and low-cost equipment options for finding them:
1. Be ready to fix the holes. Don't do this without tape, a roller, or liquid flash on site. This way, you have the ability to fix anything on the spot. (Seems like common sense, but you'd be surprised.) Fix instantly, not tomorrow.
2. Have the proper equipment to find those holes. Jake will share the value of a fog machine (just like the one you use on Halloween). Fill the building with fog and it'll force the fog out of the penetrations. You'll be able to find some large holes with this.
3. Use an IR camera, even a simple one, not need for any expensive or fancy equipment. In some cases, it may not be effective, but Jake will explain when it's good to use.
4. Use your ears. Air moving through a cavity makes a noise, but how loud can you make that noise? Jake will explain how to do this.

Glad to see I wasn't crazy in purchasing a fog machine to do this.
Question is in an already built home, 30+ years old how would you seal a leaky sill plate with a brick exterior? I'm thinking I could pull all the base boards on exterior walls to expose the bottom of the sheetrock. If it's all the way to the concrete cut about an inch off to expose the bottom plate.

What is the best way to mechanically get new fresh air into the house or out of the house? Basically whats the best way to have clean air when you have such a tight house?

Jake,
I love this stuff, great video! Brother, I would love to know the name and model of the Fog Machine and that FLIR IT Camera that was only a couple hundred dollars. :)
Cheers,
Eric
