Quick Answer
Okay, that insulation dust is a nightmare, I get it. For a basic cleanup after a small job, you can probably handle it yourself with some good plastic sheeting, painter's tape, and a shop vac with a HEPA filter. Expect to spend $50 to $150 on supplies. But if that dust has gotten everywhere, especially into your HVAC vents, don't mess around. Call a professional. A real deep clean from a pro will run you anywhere from $400 to $1,200, but it gets done right.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Identify the type of blown-in insulation (cellulose, fiberglass, mineral wool) to understand the dust properties.
Step 2
Assess the extent of the dust and debris spread (confined to attic, spread to living spaces).
Step 3
Determine if the dust is fresh from a recent job or older, settled dust.
Step 4
Check for any ongoing sources of dust (e.g., open insulation bags, unsealed entry points).

When to Call a Professional Insulation
- When dealing with large quantities of insulation dust and debris that has spread throughout the home.
- If allergic reactions or respiratory issues persist after initial cleanup attempts.
- When the insulation removal process is extensive and requires specialized vacuum equipment.
- If asbestos insulation is suspected (requires specialized abatement).
- If the attic space is difficult to access or navigate safely for thorough cleaning.
- If you confirm the dust has entered your HVAC ductwork.
Prevention Tips
- Use proper containment barriers (e.g., plastic sheeting, zippered doors) around the work area during installation or removal.
- Wear appropriate Personal Protective Equipment (PPE) including N95 or P100 respirators, goggles, gloves, and disposable coveralls.
- Ventilate the work area adequately using fans and open windows (if safe and practical) to minimize airborne dust.
- Use a shop-vac with a HEPA filter for initial cleanup, not a regular household vacuum.
- Mist the insulation lightly with water (if not an electrical hazard) to reduce dust during removal.
- Seal off HVAC registers and returns in living spaces to prevent dust from entering the ventilation system during work.
- Clean surfaces with damp cloths after vacuuming to pick up fine dust particles.
