Cavity Wall Insulation in Malahide
Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Malahide village, Malahide marina, Robswall and the surrounding area.
Cavity Wall Insulation for Malahide homes
Malahide's 1990s and 2000s estates through Robswall and Yellow Walls were usually built with partial-fill cavities, insulation boards fixed against the inner leaf with a clear gap behind the outer. Whether the remaining gap can be filled depends on its width and condition, which a borescope check settles. Period homes near the village and seafront have solid walls and need a different approach.
How homes in Malahide lose heat
The period and pre-war homes lose heat through solid walls, suspended floors and sash windows, and the seafront ones are exposed to wind off the estuary. The 1990s and 2000s estates were built with partial-fill cavities and modest attic insulation; they usually rate C and respond well to attic top-ups, cavity checks and airtightness work.
Typical housing: Period stock around the village and marina, pre-war seafront semis, and 1990s and 2000s estate housing inland through Robswall and Yellow Walls.
Planning: The village and parts of the seafront are Architectural Conservation Areas.
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.

The village and parts of the seafront are Architectural Conservation Areas. We check the planning position for your specific house at the free survey, before any work is specified.
Is there a grant for cavity wall insulation in Malahide?
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.
