External Wall Insulation for Greystones homes
Harbour-side Greystones homes exposed to sea wind and driving rain often suit external insulation better than cavity fill. We specify renders and details for coastal exposure. Mid-century homes inland may suit either, depending on the wall.
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 external wall insulation works
External wall insulation fixes insulation boards to the outside face of the walls and finishes them with a reinforced render system. Because the insulation is continuous around the house, it deals with the cold bridges at floors and party walls that internal insulation struggles with, and the work happens outside so you can stay living in the house.

External Wall Insulation in Greystones: questions
Do you carry out external 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 external 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 external wall insulation in Greystones?
SEAI individual grants for external wall insulation are €8,000 for a detached house, €6,000 for a semi-detached or end-of-terrace, €3,500 for a mid-terrace and €3,000 for an apartment, for homes built and occupied before 2011. The whole wall surface must be treated. 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.
Does external wall insulation need planning permission?
Most external insulation is exempted development, but protected structures, Architectural Conservation Areas and changes that affect the look of a terrace can need planning. We check this at survey stage.
Will external insulation stop damp?
It keeps the wall warmer, which reduces condensation and mould on internal surfaces. Rising or penetrating damp has to be dealt with first, which is why we test the walls before specifying a system.
How long does an external wall insulation job take?
Five to ten working days for a typical semi-detached house, depending on weather. Render cannot be applied in rain or frost, so we plan around the forecast.
