âś… Why Remove Old Loft Insulation?
Over time, insulation materials degrade, absorb moisture, and can become a magnet for pests and mould. Outdated or damaged insulation can actually reduce your home’s energy efficiency, putting a strain on your heating bills—and your health.
⚠️ Signs It’s Time to Remove Loft Insulation
Here are the top indicators that your loft insulation may need replacing:
1. It’s Over 15-20 Years Old
Insulation doesn’t last forever. If your loft insulation is over 15–20 years old, it’s likely underperforming or breaking down. Modern insulation is far more efficient and meets current building standards.
2. Damp, Mould, or Water Damage
Wet insulation loses its effectiveness. If you’ve had a roof leak or noticed signs of damp or mould, it’s essential to remove the affected insulation to prevent further damage and potential health risks.
3. Rodent or Pest Infestation
Rodents love nesting in old insulation. If you see droppings, nests, or hear scratching noises in your loft, it’s time to remove and properly disinfect the area.
4. Unpleasant Smells
Musty or foul odours coming from the loft can indicate mould, pest activity, or trapped moisture. Old insulation can harbour these smells and should be removed to keep your home fresh and hygienic.
5. You’re Upgrading Your Insulation or Renovating
Planning to install modern, eco-friendly insulation? Removing the old layers first ensures better performance and avoids issues with trapped moisture or compression.
6. Increased Energy Bills
Poor insulation = poor heat retention. If your heating bills are rising without explanation, your old insulation could be to blame.
