Home >> Windows & Doors Tallaght
Tallaght is the largest town in South West Dublin, developed rapidly from the 1970s onwards along the N81 and N82 corridors, creating a vast stock of semi-detached and terraced homes in estates such as Kilnamanagh, Old Bawn, Fettercairn, and Springfield. The sheer volume of 1970s to 1990s housing in Tallaght means thousands of properties still carry the original double glazing installed during construction, now decades past its peak performance. We fit A-rated uPVC windows, composite front doors, French doors, and sliding patio doors across all of Tallaght's estate types.
SEAI grants of up to €5,600 are accessible to Tallaght homeowners upgrading to A-rated glazing, and Airtight manages the complete application as part of every project. We are SEAI registered and family-owned since 2003, and have completed over 5,247 homes across South Dublin and the wider Leinster region. Our experienced installation team handle all work, backed by a 10-year workmanship guarantee, and we return a written fixed-price quote after your free survey.
