How to insulate a crawl space – installation guide

Crawl space is never a place a homeowner wants to look into and clean. The dirt, rubbish, and sometimes even mold would scare off anyone. Hence, crawl space is almost always overlooked and left forgotten. But our Envirosmart experts will convince you otherwise. There are a few reasons why you should invest in improving your crawl space, and all for the sake of your house’s energy efficiency and your family’s health.

To lower the energy bills and enhance comfort levels, we recommend installing insulation in the crawl space. Envirosmart Solutions has helped countless homeowners, and each of our customers is more than happy with the results.

This blog will teach you everything you need to know about crawl space insulation and how to DIY this project.

Does Installing Crawl Space Insulation Make a Difference?

Without second thoughts – yes! At Envirosmart Solutions, we know for a fact that installing insulation in the crawl space not only keeps the whole area cleaner but also doesn’t let cold air enter your house.

Since the crawl space is what separates your house structure from the ground, and more often than not, the area is “naked” or unfinished, it welcomes dirt, moisture, and humidity to enter. As a result, homeowners are often baffled by discovering spreading mold, nasty odor, and even spotting damaged joists that actually keep your house from falling down. Cleaning the crawl space is truly hard work and sometimes can only be done with proper equipment.

Insulation can maintain consistent temperatures in the living space and, hence, reduce energy consumption because you no longer need to run your heating system at the maximum capacity to stay warm. Moreover, insulation protects pipes in winter, which is especially beneficial for cold regions where pipes tend to crack.

When Is the Time to Start Insulating Your Crawl Space?

There are a few warning signs that can indicate it is time to insulate your crawl space. Before you have to gear up and go down the rabbit hole that is your crawl space, try standing on the floor that is right above the crawl space. If you notice that the subfloor is considerably colder than other floors, this means the current insulation, if there is any, is failing at its job.

Another method of checking the condition of your crawl space is for the bravest – actually going down the house structure with a flashlight and investigating how damaged or wet the insulation of the crawl space is. Unfortunately, if the insulation is wet, it will have to be replaced. The same goes if your crawl space is wet, as it leads to foundation cracks and may attract rodents.

Finally, the easiest way to make sure your insulation is in good shape is to hire a professional team like Envirosmart Solutions. We offer annual check-ups and inspections of your crawl space and attic in one package to give you peace of mind and ensure your family stays healthy and warm.

Can You Insulate a Crawl Space Without Prepping It First?

Insulation in the crawl space will work to your benefit only when it’s installed properly, meaning in the clean and dry crawl space. Before we get to the installing guide, make sure to remove excess water and moisture, mend leakages from pipes, if any, and clean the area from debris, mold, and infestation.

In case the workload is too much for you and you require professional help, Envirosmart Solutions offers a crawl space clean-up service for an affordable price.

How to Install Insulation in a Crawl Space: Step-by-Step Guide

Now, to the most important part – a step-by-step guide on how to install insulation in the crawl space. We highly recommend not skipping any step in the DIY project to have the best final results.

  1. Choose insulation material: This can be anything from fiberglass batt, rigid foam board, or closed-cell foam insulation.
  2. Remove the existing insulation: Gear up with protective gloves, mask, and goggles, and scrap the damaged insulation from your crawl space.
  3. Remove water and moisture: As we’ve mentioned earlier, prepping your crawl space before installing new insulation is very important. You can use fans or heaters, which can do wonders when removing excess water.
  4. Install a vapor barrier: A vapor barrier will protect the crawl space from moisture coming from the ground. Envirosmart Solutions can take this task off your shoulders and install a vapor barrier so that it prevents mold and fungus from damaging the house foundation.
  5. Install insulation in the crawl space: To properly insulate your crawl space, make sure to cover the entire area, especially around the joists, pipes, and wiring. The layer of insulation should fit snugly but not too tight.

Remember to wear protective gloves, a mask, and eye goggles at all times! Don’t hesitate to get in touch with us if you need professional help with any of the steps. Our experienced team will gladly help you with insulating your crawl space.
