Insulating Your Crawl Space

Crawl spaces, subfloors and basements that aren’t properly insulated are prone to water damage from moisture in the ground under your house. This can cause inconvenient (and potentially costly) problems.

If your crawl space is ventilated, it can be hard to keep warm in the winter, and during the summer, it can be difficult to dehumidify, which can result in higher levels of moisture. The professionals at Accurate Insulation can insulate the subfloor and between the floor joists.

For unventilated crawl spaces, sealing between the house and crawl space isn’t as important, so in our opinion, it’s best to install wall insulation.

Insulating the crawl space can help:

  • Reduce your utility bills and maximize the energy efficiency of your home
  • Make your home a more comfortable space
  • Improve the efficiency of your air conditioner
  • Reduce noises on different levels inside (especially useful if your crawl space is used as a living space)
  • Contribute to a healthier environment inside your home

New Construction & Retrofit Projects

The Accurate Insulation team installs retrofit (re-insulation) and new construction crawl space insulation. We have experience installing different types of insulation in ventilated and unventilated crawl spaces, including:

Ventilated vs. Unventilated Crawl Spaces in DC & Maryland

When considering unvented vs. ventilated crawl spaces, your first opinion might be “unvented is better.” It makes sense. A tightly sealed crawl space must provide better protection and better insulation, right?

Not necessarily. The common denominator for most crawl space problems is moisture. Whether your crawl space is ventilated or unventilated is secondary to whether moisture can accumulate.

Drainage is Key

Crawl spaces are tiny basements with little to no lighting, limited access, and a catchall for leaves and debris. We don’t pay much attention to them until we notice a moisture problem in the living area adjacent to the crawl space. Whether your crawl space is ventilated or unventilated, it must have adequate drainage.

Exterior draining solutions include:

  • Foundation wall damp proofing or waterproofing
  • Grading around the foundation that slopes away from the house
  • Gutter downspouts
  • Subsurface draining system

Interior drainage solutions include:

  • Drain on the crawl space flooring plumbed to a sewer drain
  • Moisture-resistant insulation

The Best Insulation for Crawl Spaces

Fiberglass

If your crawl space is ventilated, the best insulation is fiberglass insulation. Depending on your crawl space moisture retention and layout, we may recommend:

Blown-in fiberglass costs less and gets into those hard-to-reach places. It may also be better for the environment. But if you have a dry crawl space without moisture issues, batts are a great choice and provide superior insulating properties.

Rigid Foam

If your crawl space is unventilated, the best insulation is rigid foam insulation. Rigid foam board maximizes energy efficiency. We use:

  • Expanded polystyrene (EPS), which is good for new homes as well as retrofitting
  • Extruded polystyrene (XPS), which is extremely durable
  • Polyisocyanurate (polyiso), which is typically for attics
