Does Insulation Need to Be Removed After Flooding?

Does Insulation Need to Be Removed After Flooding? - Image 1

If your home is in an area that experiences flooding from Hurricane Florence - or any other strong storms - your basement or crawl space could get wet quickly. The water could affect the insulation in your walls or under your home and depending on the type of insulation you have, Dr. Energy Saver may need to replace it in order to avoid dangerous mold growth. Let's take a look at how we will approach the following types of insulation if your home endures flood water. 

Will My Insulation Have to Be Removed?

Fiberglass 

Fiberglass is very common, but when it takes on a lot of water, it can first of all no longer insulate effectively, and second, will breed mold. We will analyze the damage but whether it's just moist or very wet, there's a good chance it will need to be replaced. 

Open-cell spray foam is a soft foam that will leave an indentation if you push on it with your finger. If it gets wet, it will absorb the contaminants in the flood waters -- which is really dangerous. We will have to measure the moisture content and remove anything with over 15% moisture. 

Closed cell spray foam is the type of insulation FEMA prefers for homes in flood-prone areas because it does not absorb water. It's hard and won't leave an indentation without a lot of pressure, and it won't absorb contaminants as open-cell spray foam can. In most cases, closed cell spray foam will not need to be removed after a flood, but we will still measure the moisture content to ensure it's below 15%. 

Hybrid spray foam is a cross between open and closed cell foams and their density will vary depending on manufacturer’s formula. It will absorb water and contaminants, so we will most likely need to replace it if it's been affected by flooding.
