Does Your Crawl Space Need More Insulation?

March 9, 2016

It’s the stuff of old-time horror stories: the mischief down below in the damp, dark, creaky basement.

It goes by various names: basement, cellar, crawl space or, in ancient times, the dreaded dungeon. It is the floor below the ground floor. That’s where the mystery begins, and, by the way, where home insulation installation ends. In the basement, literally.

While we at Capitol Machine, your online expert in home insulation installation, won’t delve too deeply into the mystique of the basement, we will point to the significance of ensuring your home is well protected from the cold winds whistling in the night’s darkness.

The basement is usually the floor (or floors) beneath the ground floor. Basements are either completely or partially underground, which creates a whole new dynamic for home insulation projects. The basement or crawl space typically serves as a storage area and may include a boiler, a water heater, breaker panels, furnace or other nondescript household equipment.

Going Down Under To Discover the Problem

Let’s look at the furnace. If during the bluster of winter your furnace is raging away “down thar” and your bare feet still feel the chill, it might be time to make the downward trek to answer the question: Does my crawl space need more insulation?

Older homes, before building codes were made standard in 1990, may lack adequate insulation in the lower, sub-ground-level floor.

How Long Does an Insulation Job Take?

For those happy homeowners living in warmer climates generally in the South, the fix may be as simple as installing batts insulation in the basement ceiling, according to the National Association of Realtors®. But those Southern residents might want to pay attention to our advice for their Northern counterparts.

For those living in climates that lean toward the chilly side of life, we recommend taking several steps (which, unfortunately for the superstitious, involves descending to the basement):

  • Venting Your Anger: Don’t just close the vents. Remove them and then seal up the holes.
  • No Joisting Around: Spray closed-cell foam around joist rims at the top of the foundation floors.
  • Darth Vapor: Ground or cement crawl space floors release moisture. Lay a moisture barrier of at least 6-mil plastic to block the moisture from rising.
  • No Mo: Humid households can cause basement condensation. That can elevate moisture levels down under, which can cause problems with mold. A good dehumidifier solves that problem.
  • Fill ‘Er Up: The most important step? Insulate any foundation walls with blown-in insulation. Crawl spaces and basements, settled into the cold Earth, are firmly connected to the main house. That connection can lead to temperature fluctuations in both: a freezing basement, a chilly first floor.

Loose-fill blown-in insulation is the best way to go for peace of mind over basement brouhaha. Loose-fill insulation is fast, efficient and powerful. Our Capitol Machine Model 125 – with its series 4 positive displacement blower – blows nearly 100 bags of fiberglass per hour.
