Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Ranelagh village, Sandford Road, Beechwood and the surrounding area.
Cavity Wall Insulation for Ranelagh homes
Ranelagh's Victorian and Edwardian red-bricks have solid walls, so cavity fill is rarely relevant to the main house. Rear extensions added from the 1970s onwards sometimes have cavity walls, and those can be checked and filled. For the original walls, internal insulation, with external insulation on rendered rear returns where planning allows, is the right approach.
How homes in Ranelagh lose heat
Solid 9-inch brick walls, suspended timber floors, open chimneys and large sash windows mean many Ranelagh homes rate E to G. Rear returns are often a mix of original brick and later block additions, so heat loss differs from front to back. Draughts are a large share of the loss.
Typical housing: Victorian and Edwardian red-brick terraces, typically three windows wide, with high-ceilinged period interiors and long rear gardens.
Planning: Most of Ranelagh is within Architectural Conservation Areas and many terraces are protected structures, so external insulation on front elevations is rarely an option.
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.

Do you carry out cavity wall insulation in Ranelagh?

Is there a grant for cavity wall insulation in Ranelagh?
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.
