Insulation Contractors in Dublin
Dublin has the widest spread of building eras in the country. Victorian and Edwardian red-brick terraces through the inner suburbs are solid wall — usually 9-inch brick with no cavity at all. The 1930s to 1960s semi-detached belt is early cavity, often narrow and sometimes partially filled with debris. The 1970s onward estates are conventional cavity block.

What houses in Dublin are actually like
Dublin has the widest spread of building eras in the country. Victorian and Edwardian red-brick terraces through the inner suburbs are solid wall — usually 9-inch brick with no cavity at all. The 1930s to 1960s semi-detached belt is early cavity, often narrow and sometimes partially filled with debris. The 1970s onward estates are conventional cavity block.
The problem specific to this area
The red-brick terraces are the interesting case. There is no cavity to fill, and external insulation over a brick façade is usually unacceptable — for planning reasons in conservation areas, and because the brick is the point. That leaves internal dry lining, which works well but costs you internal floor area and needs careful detailing at joists and reveals to avoid moving the condensation risk rather than solving it.
What we usually recommend in Dublin
Terraces almost always mean internal wall insulation, done properly with attention to thermal bridging at party walls and window reveals. The 1930s–60s semis are frequently good cavity candidates once a borescope confirms the cavity is clean and wide enough. Later estates are straightforward cavity fill.
Uninsulated Dublin red-brick commonly tests at E or F. Internal lining plus attic work usually brings it to C3–D1, and rarely better without windows and heating.

It depends on how your walls are built, not on the county alone. Exposure here is moderate, which leaves most systems on the table. The decision comes down to the construction of your particular house. Terraces almost always mean internal wall insulation, done properly with attention to thermal bridging at party walls and window reveals. The 1930s–60s semis are frequently good cavity candidates once a borescope confirms the cavity is clean and wide enough. Later estates are straightforward cavity fill.
Cost depends on the wall area, the system and the condition of the existing fabric, so a figure quoted without seeing the house is guesswork. We charge €100 for a measured survey and refund it in full against your order, so the survey costs nothing if you proceed.
If your home was built and occupied before 2011 you are likely eligible. Grant amounts vary by dwelling type — a detached house receives more than an apartment for the same measure. The current amounts by house type are set out on our SEAI grants page.
