Frequently Asked Questions
How do I know if my walls have a cavity?
Brick or block walls around 300mm thick are often cavity walls. A contractor can confirm with a small borescope survey.
How much does cavity wall insulation cost in Dublin?
Typically €1,200–€3,000. The exact price depends on access, the extent of the work and the materials needed.
When should I book cavity wall insulation?
Plan it, ideally before winter.
Are there SEAI grants for insulation?
Yes. SEAI offers grants for attic, cavity wall, internal and external wall insulation for qualifying older homes. Check seai.ie for current amounts and conditions.
Will insulation cause damp?
Not when it is installed properly with adequate ventilation. A ventilation check should be part of any insulation job.
Which insulation saves the most?
For most homes, attic and cavity wall insulation give the quickest payback. Solid-wall homes gain most from internal or external wall insulation.
