Airtight Window Systems Ltd.

Airtight is a family-owned window and door installer based in Parkwest, Dublin 12 — serving greater Dublin, Kildare and Wicklow since 2003. SEAI registered, fully insured, and a written 10-year workmanship guarantee on every job. Airtight Window Systems Ltd was founded in Dublin 12 in 2003 by Owen, who still runs the day-to-day and personally surveys most of the homes we quote. We supply and fit uPVC windows, composite doors, sliding patio doors, French doors and back doors across greater Dublin, Kildare and Wicklow. We’ve never been a franchise, never used outside fitters, never been part of a chain. Same family. Same Parkwest workshop. Same standards. Owen answers the phone himself within 24 hours and walks every customer through their options before quoting. Today we’re an SEAI registered contractor — eligible for the 2026 €5,600 grant — fully insured and backed by a written 10-year workmanship guarantee on every install.
