Cavity Wall Insulation in Greystones
Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Greystones harbour, South Beach, Charlesland and the surrounding area.
Cavity Wall Insulation for Greystones homes
Mid-century homes in the centre of Greystones often have empty cavities that can be filled. Near the harbour, exposure to driving rain off the Irish Sea can make cavity fill unsuitable, so we assess each wall. Newer estates such as Charlesland usually have partial-fill cavities already.
How homes in Greystones lose heat
Harbour-side homes face wind and salt off the Irish Sea, with solid walls that need moisture-safe insulation and draught-proofing. Mid-century homes often have empty cavities. Charlesland and similar estates rate around B3 to C2 and mostly benefit from attic top-ups and airtightness checks.
Typical housing: Coastal cottages and Victorian terraces near the harbour, mid-century estate housing through the centre, and 1990s and 2000s estates such as Charlesland on the outskirts.
Planning: The harbour area and older streets may carry conservation context.
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.

Cavity Wall Insulation in Greystones: questions
Do you carry out cavity wall insulation in Greystones?
Yes. We cover Greystones and the surrounding Co. Wicklow area, including Greystones harbour, South Beach, Charlesland. Coastal cottages and Victorian terraces near the harbour, mid-century estate housing through the centre, and 1990s and 2000s estates such as Charlesland on the outskirts.
Is planning permission an issue for cavity wall insulation in Greystones?
The harbour area and older streets may carry conservation context. 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 Greystones?
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.
