Insulation & energy surveys in Castleknock
Insulation and energy surveys in Castleknock, Laurel Lodge and Carpenterstown, mostly mid-century and 1970s to 1990s estate homes with straightforward upgrade paths.
Homes in Castleknock
Mid-century estate housing across the centre, larger detached homes near the Phoenix Park edge, and newer estates toward Carpenterstown.
The 1970s to 1990s estates were mostly built with cavity walls, some empty, some partly filled, and attic insulation well below current depth, which typically gives C3 to D2. Larger detached homes near the park have bigger roof and wall areas and often mixed-construction extensions.
Planning and conservation: Park-edge streets may carry some planning context; most estate homes allow external insulation as exempted development.
For extensions, carpentry and whole-house retrofits in Castleknock, our parent company MZCC.ie covers the same area.
