Spray foam on crawlspace walls
Crawlspaces – those nasty, damp, moldy spaces under your home that you dread entering. They’re one of the least understood parts of a home and the source of countless problems. In this post, I’ll review some of the worst problems and how to avoid them.
Crawlspaces often have two big issues:
Do you have something like this in your attic?
Do you feel like your house is always dusty, in spite of how much you vacuum and clean? Have you tried all the tricks – HEPA vacuum cleaners, air cleaners, taking your shoes off before coming in the house, washing the dog…. all to no avail?
Chances are good that you’re being plagued by a leaky duct and air handling system.
When you have leaks in your ducts (virtually all duct are leaky) dust from the attic gets sucked into the ducts and distributed throughout the house. Even if you have an excellent filtration system on your air handler, the dust can be sucked in from places that don’t get filtered, and blown into your home, usually leaving fine gray dust everywhere.
Before you call in a heating/cooling (HVAC) contractor, there are a few steps that you can take yourself.
A missing barometric damper
A family friend recently told me of “issues” with their home heating system – “when it runs, the lights get halos around them from all the soot in the air.”
I couldn’t believe it when I heard this, and immediately warned him that the condition likely is making his family sick and could easily kill them. No joke.
Carbon monoxide poisoning is the “leading cause of accidental poisoning deaths in America” – it’s colorless, odorless and quickly affects your brain, knocking you out then killing you. In lower amounts, it can lead to chronic headaches, dizziness, depression, nausea and a host of other problems.
As we tighten up our homes to make them more energy efficient, we have to be particularly vigilant about keeping any combustion devices in the home tuned up and properly vented.
Let’s look at this in more detail….
This is wasting more energy than leaving a window open
I admit it – I go crazy when I see leaky ducts. I’m not talking about ducts that have little leaks, I’m talking about problems that cost you hundreds of dollars per year and could be fixed in a few minutes with a piece of tape.
Incompetent heating contractors hate me. Why? Because I’m on a mission to give you the information you need to know when they’re ripping you off. On the other hand, quality contractors love my information because I arm you with knowledge so you can tell the difference between the good ones and the bad ones.
