BER Assessments in Castleknock
Castleknock and the western Dublin corridor is a well-established residential area that developed primarily from the 1970s to 2000s. The Castleknock and Laurel Lodge estates from the 1980s–90s are popular family areas with three and four-bed semi-detached homes. Carpenterstown and Diswellstown feature newer developments from the 2000s. Chapelizod, nestled along the Liffey near the Phoenix Park, has a charming mix of older village properties and modern apartments. Ashtown has seen significant apartment development in recent years. Most 1980s–90s homes in Castleknock rate C to D, while newer builds typically achieve B2 or better.

BER Tips for Castleknock Homeowners
Castleknock's 1980s–90s housing estates are generally well-built with cavity block walls, but many have only partial cavity insulation from the original construction. A cavity wall insulation top-up combined with an attic insulation increase can improve your BER by one to two grades at modest cost. Chapelizod's older village houses may have solid stone or brick walls requiring more specialised approaches. If you're in one of the newer Diswellstown or Hansfield developments and planning to sell, your original BER cert may be close to its 10-year expiry, it's worth checking the date and getting a fresh assessment if needed.
