Retrofitting & Insulation in Castleknock.

Castleknock · The area

Why retrofitting and insulation in Castleknock are a familiar brief.

Castleknock retrofit briefs are dominated by the mid-century estate housing across the centre and the larger detached homes near the Phoenix Park edge, both of which carry cavity-wall construction with variable cavity-fill quality and original glazing largely already replaced. The retrofit move that delivers the largest single uplift here is cavity-fill (or re-fill where the original has settled) alongside attic-insulation top-up and airtightness detailing at the wall-ceiling junction. The larger Phoenix Park edge homes support more comprehensive retrofit packages with MVHR and floor insulation pulled in alongside. SEAI grant eligibility is strong for most Castleknock retrofits. The newer outer estate developments are already to a higher build spec and retrofit scope is targeted (attic top-up, MVHR) rather than wholesale.

Retrofitting & Insulation · How we run it

Retrofitting & Insulation in Castleknock, the way it should be done.

Retrofitting an Irish home is where craftsmanship and building science meet. Marcin holds certification from Engineers Ireland in Retrofitting and Energy Efficiency, has completed advanced retrofit skills training at Mount Lucas National Construction Training Campus, and is a certified Baumit installer for external wall insulation systems.

Our retrofit work covers the full envelope: external wall insulation systems applied and rendered correctly so the detailing at reveals, eaves and sills is right; internal wall insulation where EWI is not practical (terraced fronts, protected facades); attic insulation upgrades to current spec; airtightness membranes detailed and tested; and heat-recovery ventilation specified to keep the air fresh in the airtight envelope.

For full-home retrofits we coordinate the BER assessment, the works package and the certification so the project is properly graded and grant-eligible where applicable.

The work in Castleknock runs to the same specification we apply everywhere across Dublin and Leinster. Materials, sub-trade coordination, planning context and final certification are all managed from one studio. If your project is on the dublin side of the city, expect site visits within the working week and same-day responses on WhatsApp.
