SEAI grant
No second measure
housewrap.ie is not SEAI or a government body and does not award grants.
SEAI's rule: a home that already had an external wall insulation grant can't get a second wall insulation measure.
You can still get a price for repairs or new work, without the grant.
SEAI grant
Not eligible
housewrap.ie is not SEAI or a government body and does not award grants.
SEAI's wall insulation grants are only for homes built and occupied before 31 December 2010.
You can still get a price. Leave your number and one contractor rings you about the house and what the work would cost.
