Removing old fiberglass loft insulation involves careful planning, proper safety measures, and specific techniques to ensure safe and effective removal. Here’s a comprehensive guide covering types of fiberglass insulation, dealing with contaminated insulation, methods and techniques used, manpower requirements, post-removal cleaning, and key questions to ask a removal company.
1. Types of Fiberglass Insulation
Batt Insulation: Large, pre-cut panels commonly used in lofts. They are easy to install but can be difficult to remove if compacted or degraded over time.
Loose-Fill Insulation: Made of small, lightweight fiberglass particles blown into the loft space. Removal requires careful handling to minimize airborne particles.
Roll Insulation: Similar to batt insulation but comes in long rolls that are cut to size. Removal is similar to batt insulation.
2. Contaminated Fiberglass Insulation
Identifying Contamination: Fiberglass insulation can become contaminated with mold, mildew, dust, rodent droppings, or asbestos. Look for discoloration, dampness, or signs of pest activity.
Handling Contaminated Insulation: Use additional safety measures such as full-body coveralls, N95 or higher respirators, and goggles. Contaminated materials must be sealed in heavy-duty plastic bags and disposed of according to local hazardous waste regulations.
3. Methods and Techniques Used
Preparation:
Safety Gear: Ensure all workers wear appropriate PPE including gloves, goggles, respirators, and disposable coveralls.
Ventilation: Ensure good ventilation in the loft to reduce dust accumulation and maintain air quality.
Isolation: Seal off the work area with plastic sheeting to prevent contamination of other parts of the house.
Removal Techniques:
Manual Removal: Use hand tools such as utility knives, shovels, and rakes to remove batt or roll insulation. For loose-fill insulation, use a HEPA-filtered vacuum to minimize dust.
Bagging and Disposal: Double-bag insulation in heavy-duty plastic bags, seal them, and label as hazardous if contaminated. Follow local disposal regulations for proper handling.
Cleaning: Use a HEPA vacuum to clean up remaining dust and particles. Damp-wipe surfaces to remove any residual fiberglass fibers.
4. Manpower Requirements
Team Size: Typically, a team of 2 to 4 workers is sufficient for most loft insulation removal projects. Larger lofts or heavily contaminated spaces may require additional personnel.
5. Post-Removal Cleaning
Surface Cleaning: Thoroughly vacuum all surfaces using a HEPA vacuum cleaner. Damp-wipe surfaces to capture any remaining dust and fibers.
Inspection: Inspect the loft for any signs of remaining insulation or contamination. Address any structural issues or damages before installing new insulation.

What is the estimated timeline for completing the removal and cleaning process?
References and Guarantees:
Can you provide references from previous clients?
Do you offer any guarantees or warranties on your work?
Conclusion
Removing old fiberglass loft insulation requires careful planning, proper safety measures, and specific techniques to ensure safe and effective removal. Whether dealing with standard or contaminated insulation, it’s crucial to follow best practices for preparation, removal, and disposal. Engaging a professional removal company with the right expertise and equipment can ensure the job is done safely and efficiently. Always ask key questions to verify the company’s credentials, experience, and commitment to safety and compliance.
I highly recommend these guys who recently helped us clear and clean out our loft in Newcastle after we had rodents in. They removed old junk and the old insulation then cleaned up the rodent droppings and hoovered the loft out. They were very friendly, made sure no dust and dirt got into our home and cleaned up after themselves. We are elderly people so we couldn't do this but they did everything in half a day. We tried all over to get someone to do the works for us but these guys were the only ones to come out and give us a qoute. Would use again if we ever have another rodent problem.
