SEAI Grant 2026: Up to €5,600 off A-rated windows & doors · Call 01 822 8982 See grant details →
Home >> Windows & Doors Firhouse
Firhouse developed through the 1980s and early 1990s on the southern fringes of Dublin, with estates such as Ballycullen, The Gallops, and Woodstown creating a large stock of detached and semi-detached homes. These properties sit at a higher elevation than much of South Dublin, exposed to south-westerly weather rolling in off the Dublin Mountains. We fit A-rated uPVC casement windows, composite front doors, tilt-and-turn windows, and sliding patio doors designed for the higher-altitude conditions common to Firhouse and the Knocklyon border.
A 24-hour response is the first step for every Firhouse project, giving homeowners a written fixed-price quote with no obligation after survey before any work is agreed. Airtight is SEAI registered and has been fitting windows and doors in South West Dublin since 2003, completing over 5,247 homes in total. Our own directly employed fitters carry out every installation with a 10-year workmanship guarantee, and as an SEAI registered installer, eligible upgrades qualify for grants up to €5,600 (you apply directly through SEAI).
