Fiberglass insulation is an effective and widely-used material for insulating homes and commercial buildings. However, during installation or removal, fiberglass can create a mess and pose health risks if not handled properly.

In this comprehensive guide, we will discuss how to clean up fiberglass insulation to ensure a safe and healthy environment.

1. Understanding Fiberglass Insulation

Fiberglass insulation is a synthetic composite material most commonly found in attics, walls, and basements. It is made of fine glass fibers, which can cause irritation to the skin, eyes, and respiratory system if inhaled or touched.

As a result, it is crucial to take proper precautions when working with this material. It keeps homes warmer in winter and cooler in summer.

What is Fiberglass Insulation?

Fiberglass insulation is a lightweight, flexible material made from tiny glass fibers. It is commonly used to insulate walls, ceilings, and floors, providing excellent thermal and acoustic insulation. Fiberglass is fire-resistant, moisture-resistant, and relatively easy to install.

Health Risks Associated with Fiberglass Insulation

Exposure to fiberglass insulation can cause several health issues, including:

  • Skin irritation: Tiny glass fibers can get embedded in the skin, causing redness, itching, and rashes.
  • Respiratory problems: Inhaling fiberglass particles can irritate the nose, throat, and lungs, leading to coughing, wheezing, and difficulty breathing. Prolonged exposure may aggravate existing respiratory conditions like asthma or bronchitis.
  • Eye irritation: Fiberglass particles can cause redness, itching, and a burning sensation in the eyes.

It is essential to take proper safety measures when working with roofing materials with fiberglass insulation to minimize these risks.

2. Personal Protective Equipment (PPE) for Cleaning up Fiberglass Insulation

When cleaning up fiberglass insulation, it is crucial to wear appropriate personal protective equipment (PPE) to protect yourself from potential health risks.


Wear long-sleeved shirts, long pants, and closed-toe shoes to cover as much skin as possible. Overalls or disposable coveralls are also an excellent option for added protection.


Use heavy-duty work gloves made of leather or other durable materials to protect your hands from contact with fiberglass or fibers.

Eye Protection

Wear safety goggles to shield your eyes from fiberglass particles, ensuring a snug fit to prevent particles from entering.

Respiratory Protection

Use a half-face or full-face respirator with a HEPA filter to protect your lungs from inhaling fiberglass dust particles. A disposable dust mask may not provide adequate protection against small fiberglass fibers.

3. Preparing the Area

Before cleaning up fiberglass insulation, it is essential to prepare the area to minimize the spread of particles and ensure a thorough cleaning.

Isolate the Area

Close off the area where the fiberglass insulation is present to prevent particles from spreading to other parts of the home or building. Use plastic sheeting and tape to seal off doorways, vents, and windows.

Remove Loose Items

Clear the area of any loose items, including furniture, rugs, and personal belongings. If these items have been exposed to fiberglass insulation, they may require cleaning or disposal.


Ensure proper ventilation in the area by opening windows and doors, if possible. This will help reduce the concentration of fiberglass particles in the air.

Cleaning up Fiberglass Insulation Dust

After preparing the area and washing clothes and donning appropriate PPE, follow these steps to clean up fiberglass insulation dust:

Step 1

Locate the source of fiberglass dust, which may be in air ducts, walls, ceilings, or floors. If the circulating broken fiberglass dust is in the air duct system, consider replacing the entire system, as it may be challenging to remove all fiberglass particles.

Step 2

For construction or renovation projects, wet the fiberglass insulation with a water hose to minimize dust. After wetting the insulation, carefully remove it from the walls, ceilings, or floors in sections.

Step 3

Gather the removed insulation and place it in heavy-duty plastic trash bags. Dispose of these bags at a local landfill or incineration facility.

Step 4

Use a HEPA vacuum cleaner to remove fiberglass insulation dust from surfaces, including floors, walls, and ceilings.

A regular vacuum cleaner may not provide adequate filtration and may release some fiberglass dust particles back into the air.

Step 5

Clean surfaces thoroughly with a damp cloth and soapy water, paying attention to crevices and corners. Rinse the cloth frequently to avoid spreading dust.

Step 6

Sweep the area to collect any remaining fragments, and dispose of them in a sealed trash bag.

Step 7

Dispose of contaminated clothing and protective gear, or launder them separately from other clothing.

5. Cleaning Furniture and Personal Belongings

Furniture and personal belongings exposed to fiberglass insulation may require cleaning or disposal.

Upholstered Furniture

If upholstered furniture has been contaminated with fiberglass insulation, it may be challenging to clean thoroughly. Consider disposing of these items and sealing them in trash bags to prevent the spread of particles. One tool works very well from at removing excess material, check it out here.

Carpets and Rugs

Carpets and rugs exposed to fiberglass insulation should be vacuumed with a HEPA vacuum cleaner, then steam cleaned or professionally cleaned to remove all particles.

Bedding and Clothing

Launder bedding and clothing separately from other items, using a gentle detergent and warm water. If items remain contaminated after washing, consider disposing of them.

Cleaning the Attic

The attic may require intensive cleaning after fiberglass insulation removal, including:

Removing and Replacing Insulation

Remove all insulation from the attic to eliminate dust and fibrous material. Consult a professional to assess the extent of the project and provide a quote.

Sealing Air Ducts and Vents

Ensure all air ducts and vents are properly sealed to prevent the spread of fiberglass particles throughout the home.

Installing HEPA Filtration

Install a HEPA filtration system to improve air quality and remove any remaining fiberglass particles from the air.

Post-Cleanup Procedures

After cleaning up fiberglass insulation, follow these steps to ensure a safe and healthy environment:

Ventilate the Area

Open windows and doors to allow fresh air to circulate and disperse any remaining particles.

Monitor for Symptoms

If you experience any symptoms of fiberglass exposure, such as skin irritation, respiratory problems, or eye irritation, seek medical attention.

Regular Maintenance

Regularly inspect and maintain your insulation to prevent future issues. Schedule routine inspections with a professional to ensure the insulation remains in good condition and replace it as needed.

Rental Properties and Landlord Responsibilities

If you are a tenant in a rental property, it is the landlord’s responsibility to address fiberglass insulation issues. Report any problems to your landlord and ensure they hire a professional to clean up the insulation.

Finding a Professional for Insulation Cleanup

When hiring a professional to clean up broken fiberglass and insulation, interview several companies to find the most experienced and reputable one. Ask about their experience, services offered, and estimated cost. Remember, your health is the priority, so choose a company that will ensure proper cleaning and removal of fiberglass insulation.

Cleaning up fiberglass insulation can be a daunting task but is critical for maintaining a healthy living environment and avoiding fiberglass contamination. Professional help may be necessary for a thorough and safe cleanup.

By following the steps outlined in this guide on how to clean up fiberglass insulation, you can protect your health and enjoy a clean, safe living space.
