Cavity Wall Insulation in Sandyford
Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Sandyford Hall, Stepaside, Carrickmines and the surrounding area.
Cavity Wall Insulation for Sandyford homes
Sandyford's 1970s and 1980s semis and detached homes are mostly cavity-built, and many cavities were left empty or only partly filled when the houses went up. A borescope check through a small hole confirms the width and condition, and if suitable, a bonded bead fill is injected from outside in a day with no mess indoors. Homes higher up toward Stepaside face more wind-driven rain, so we check exposure on each elevation before recommending a fill.
How homes in Sandyford lose heat
The older estates were built with cavity walls that were often left empty or partly filled, thin attic insulation and early double glazing, which typically leaves them in the C to D BER range. The newer Stepaside and Carrickmines homes perform better but often have airtightness gaps around downlights and attic hatches. Being on the foothills of the Dublin Mountains, homes here also sit in a slightly colder, windier spot than the city.
Typical housing: 1970s and 1980s detached and semi-detached homes around Blackthorn and Sandyford Hall, with newer estates running up into Stepaside and Carrickmines.
Planning: Little conservation constraint on the estate housing, so external wall insulation is usually exempted development where it is needed.
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.

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.
