Check attic airflow before adding insulation
Adding insulation without leaving a path for air at the eaves can trap moisture. That is a reason to inspect airflow. It is not a diagnosis that your home has mould. It is not proof that insulation caused a stain. No independently verified Cork vent-labour range was found. UK figures are not used as Cork prices. Ask the surveyor to look at the eaves with the hatch open.
What to look at with the insulation job
Soffit or eaves vents, blocked insulation stuffed into the eaves, and any wet staining on the rafters. SEAI asks for a continuous eaves gap of at least 10mm, and 25mm where insulation would otherwise pinch it. Ask the surveyor to say whether they will keep or restore that path when they add material. A top-up that packs the eaves shut is a poor trade. Comfort upstairs is not worth trapped moisture.
What this page is not
It is not a mould clinic, a leak finder, or a promise that extra vents will fix condensation. Condensation has more than one cause. If you see black staining or a leak, say so on the form and expect a specialist look rather than a remote answer. This site will not remotely diagnose a stain.
Why there is no Cork vent price here
A 2026 evidence pass still found no independently verified Cork or Irish labour range for eaves vents. UK price guides and a Limerick firm's own marketing band are not Cork prices. This page stops at the decision: check airflow with the insulation job. Ask for a written extra if vents are needed.
How this sits beside grants and cost
A grant job still needs the attic assessed as a whole. Airflow, existing material and access belong in the same survey. The cost page does not publish a Cork vent-labour figure. Ask for a written extra if vents are needed.
FAQs
Check attic airflow before adding insulation FAQs
How much do extra roof vents cost in Cork?
This site does not publish an Irish vent-labour figure. UK price guides exist and are not Cork prices. Ask for a written extra if vents are needed.
Does extra insulation always cause condensation?
No. Condensation has more than one cause. Blocking eaves can contribute. A leak is a different problem. Do not treat every stain as an insulation fault.
Should I add vents before insulation?
Ask the surveyor to check the path that already exists. Extra vents are a finding, not a default add-on for every Cork loft.
Can I pack insulation into the eaves?
Do not block the airflow path. SEAI asks for a continuous eaves gap of at least 10mm. Ask how the installer will keep that gap when they add depth.
