Cavity Wall Insulation for Stillorgan homes
Stillorgan's housing spans the change from solid to cavity walls, so a borescope check is essential: some post-war houses have solid or hollow-block walls that cannot be filled, while 1960s homes are usually cavity-built. Where there is a suitable empty cavity, a fill is one of the best value upgrades available, grant-aided at €1,800 for a detached house.
How homes in Stillorgan lose heat
Some of the earlier post-war houses here were built with solid or hollow-block walls rather than cavities, which a quick borescope check confirms. Typical ratings sit around D1 to E1, held back by walls, thin attic insulation and uninsulated floors. Detached homes have four exposed walls, so wall insulation has a large effect.
Typical housing: Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.
Planning: Little conservation constraint on the estates, so external insulation is usually exempted development.
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 Stillorgan: questions
Do you carry out cavity wall insulation in Stillorgan?
Yes. We cover Stillorgan and the surrounding Dublin area, including Stillorgan Village, Mount Merrion, UCD. Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.

Little conservation constraint on the estates, so external insulation is usually exempted development. 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 Stillorgan?
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.
