Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Blackrock village, Booterstown, Monkstown and the surrounding area.
Cavity Wall Insulation for Blackrock homes
Blackrock's inland mid-century estates usually have cavity walls suitable for filling, and many have never been insulated. The seafront period homes in Booterstown and Monkstown have solid walls. For any cavity home near the coast, we assess exposure to driving rain before recommending a fill.
How homes in Blackrock lose heat
Period homes along the coast have solid walls, suspended floors and big sash windows facing the sea wind, often rating E to G. The inland estates follow the mid-century pattern of cavity walls built empty or partly filled, with ratings around D.
Typical housing: Victorian and Edwardian seafront terraces, period semis through Booterstown and Monkstown, and mid-century estate housing inland.
Planning: Significant parts of Blackrock, Booterstown and Monkstown are Architectural Conservation Areas with many protected structures.
How cavity wall insulation works
Most Irish houses built from the 1960s onwards have cavity walls: two leaves of block with a gap between. Many were built with the cavity empty or only partly filled, which lets heat escape straight through. Filling the cavity is one of the best value upgrades available.

Is there a grant for cavity wall insulation in Blackrock?
SEAI individual grants for cavity wall insulation are €1,800 for a detached house, €1,300 for a semi-detached or end-of-terrace, €850 for a mid-terrace and €700 for an apartment, with higher rates for qualifying welfare recipients. Homes must have been built and occupied before 2011. Grant amounts are set nationally by SEAI and change from time to time, so check seai.ie before applying. We confirm what your home is likely to qualify for during the survey.
How do I know if my walls have a cavity?
Most Dublin homes built from the 1960s on do. A borescope inspection through a small hole confirms the cavity width and whether there is any insulation in it already.
Can cavity insulation cause damp?
Problems come from filling unsuitable walls, such as very exposed elevations or cavities blocked with debris. That is why we inspect first and only fill walls that are suitable.
Is there any mess inside the house?
No. All drilling and injection is done from outside. Inside, the only change is that the walls feel warmer.
