Common Questions

Quick answers to what homeowners ask most about attic insulation retrofits

How much does an attic retrofit actually cost?

Costs depend on attic size, current insulation condition, and ventilation work needed. We've found that homeowners in Meath typically spend between moderate and substantial amounts depending on scope. The investment usually pays back through energy savings within several years, though that varies by usage patterns and heating costs in your area.

Can I install blown fibre insulation myself?

You can, but it's trickier than it looks. You'll need to rent equipment, understand proper density and coverage, manage ventilation gaps correctly, and handle safety properly. Many homeowners find it's worth getting professional help, at least for assessment and planning. Our guides walk you through what's realistic for DIY versus when to call in experts.

What's the difference between blown fibre and batts?

Blown fibre fills gaps and irregular spaces better, which is why it's great for retrofits. It conforms to the shape of your attic, covers around obstructions, and doesn't leave air pockets like batts can. Batts work fine for new construction with regular spacing, but for older attics with quirky layouts, blown fibre typically performs better.

How do I know if my attic has moisture problems?

Look for staining on wood, visible mold growth, or that musty smell when you go up there. In winter, frost or condensation on the underside of roof decking is a sign. Poor ventilation is usually the culprit. Our assessment guide walks you through what to look for and how to fix ventilation issues before adding insulation.
