Insulation Falling Down in Crawl Space


Insulation is an important part of every home—it helps keep your home warm in the winter and cool in the summer. You should have some type of insulation in the crawl space floor and walls, and it’s essential to insulate your crawl space correctly.


Over time, insulation can fall into the crawl space, leaving homeowners with a big mess to clean up and allowing cold air to seep through your sub floor. There are ways you can prevent insulation from falling into the crawl space and remedies if the insulation has already fallen down.

What is the Best Type of Insulation for My Crawl Space?

There are many factors to consider when insulating your crawl space area. The best type of insulation will depend on the climate and the foundation type. For example, if you live in a cold climate, you will want to choose effective insulation to keep in the heat.

  • Closed-Cell Spray Foam: Closed-cell spray foam insulation is sprayed onto the walls and ceiling of the crawl space. This type of insulation very effectively prevents heat loss.
  • Open-Cell Spray Foam: If you live in a hot climate, you will want to choose insulation that helps to keep your crawl space cool. One option is to use open-cell spray foam insulation, which allows air to circulate through the crawl space. This helps to keep the space cool and prevents moisture buildup.
  • Fiberglass Insulation: Another option is to use fiberglass batt insulation, which is placed between the floor joists. Fiberglass batts are less expensive than spray foam but are not as effective at blocking heat.
  • Rigid Board: Rigid foam board insulation is another popular choice used to insulate crawl space walls. Rigid foam insulation comes in different thicknesses and is easy to install.

How Do I Keep My Insulation Falling Down in My Crawl Space?

One of the most important things you can do to keep your home warm in the winter and cool in the summer is to make sure your insulation is in good condition. A well-insulated and sealed crawl space is a warm crawl space. Sometimes insulation can slip down from the ceiling, creating an energy-efficiency problem and other crawl space issues such as moisture buildup. There are a few things you can do to prevent this from happening.

  1. Ensure the bottom of your insulation is adequately secured to the floor joists. You can do this by stapling it in place or using special clips designed for this purpose.
  2. Avoid placing storage boxes or other items directly on top of the insulation, as this can cause it to compress and lose its effectiveness.
  3. Check the condition of your insulation regularly and replace it if it starts to deteriorate.

By taking these steps, you can help ensure that your insulation will stay in place and continue to do its job.

How Do You Keep Fiberglass Insulation from Falling Down?

If you have fiberglass insulation installed in your crawl space, the last thing you want to happen is for it to fall all over. Use mechanical fasteners, such as staples or clips to attach the insulation to the studs or joists. You can also use an adhesive to glue the insulation in place. The last method is to install a vapor barrier over the insulation, which will help to keep it in place and prevent it from sag- ping.


Whichever method you choose, follow the manufacturer’s instructions carefully to ensure the best results. With a little effort, you can keep your fiberglass insulation in place and enjoy all its benefits.

How Can I Secure Insulation Under My House?

One of the best ways to reduce energy costs is to ensure your home is well insulated. Crawl spaces are often difficult to access and can be full of dust and debris. As a result, it can be difficult to get traditional insulation materials to stay in place.


One solution is to use spray foam insulation in the foundation walls. Spray foam insulation can be easily installed in hard-to-reach areas, creating a tight seal that creates an air barrier. Spray foam insulation effectively blocks heat and cold, making it an ideal choice for homes in all climates.

Should I Remove My Crawl Space Insulation?

There are a few times when you may need to remove crawl space insulation. For example, if you’re doing major repairs or renovations, you’ll need to remove the insulation to access the pipes and wiring.


You may also need to remove insulation if it’s damaged or has gotten wet, which can happen if there’s a leak in the crawl space.


Another way to know if your insulation needs removed and replaced is if you notice signs of rodents or animals getting into the space. Look out for mice droppings or other signs that animals have been underneath your home. If you notice that some critters have gotten in, it’s probably time to update your insulation.


It’s always best to consult with professional installers to ensure removing and replacing with new insulation is the best option. If you do need to replace your insulation and plan to do it yourself, make sure that you have the necessary tools and protective gear. If you aren’t the DIY type, there’s no need to worry; the professionals at Wattson Home Solutions are here to take care of the job for you!
