What does a window replacement do?
Window replacement swaps existing windows for new ones — typically upgrading from older single-glazed or early double-glazed units to modern A-rated triple-glazed PVC, aluminium, or composite frames. A full replacement involves measurement, removal of old units, fitting new frames into prepared openings, sealing for weather and air-tightness, and reinstating internal sills and architraves.
Modern window upgrades deliver significant comfort and energy improvements: noise reduction, elimination of drafts, lower heating bills, and BER rating uplift. Many Irish homeowners pair window replacement with broader retrofit work — heat pump, insulation, attic upgrade — and can claim SEAI grants for window replacement under the One-Stop-Shop scheme when done as part of a deep retrofit. Standalone window replacement does not currently attract SEAI funding directly.

How much does a window replacement cost in Ireland?
Indicative pricing — your actual quote will vary
Window pricing depends mostly on size, frame material, and glazing type. The figures below are indicative Irish ranges per window, fitted.
A standard PVC casement window (1200x1200mm) double-glazed is €450–€700 fitted. The same window triple-glazed is €600–€900. Aluminium frames are €700–€1,200 per window, composite timber-aluminium €900–€1,500. A typical 3-bed semi (8–10 windows) full PVC replacement runs €5,500–€9,500 fitted. Sash windows in period properties are €1,200–€2,500 per window due to specialist construction. Bay windows are typically €1,800–€3,200 each.
These are indicative ranges based on typical Irish jobs. Final pricing depends on scope, materials, urgency, and the trader you choose. On Jobiit you'll receive itemised quotes (labour, materials, VAT) so there are no surprises.

Window Replacement FAQs
When should I replace windows vs repair them?
Replace if: condensation between the panes (failed seal), frames warped or rotting, draughts you can feel even with windows closed, or you can hear conversations clearly through closed windows. Repair if: a single broken pane (cheaper to replace just the glazed unit, €120–€280), failed handles or hinges (€80–€180), or worn rubber seals (€60–€120). Wholesale replacement makes sense once 30%+ of windows show issues.
Triple glazing vs double glazing — worth the difference?
Triple glazing typically costs 20–30% more than equivalent double glazing. The thermal performance gap is meaningful (U-value 0.8 vs 1.2 W/m²K), particularly for north-facing windows and homes targeting heat pump conversion. For typical homes on gas heating, payback on the upgrade alone is 12–20 years. For homes going to heat pump or aiming for B2 BER, triple glazing is usually worth it. Most installers will quote both options.
PVC vs aluminium vs timber — which to choose?
PVC: most affordable, low maintenance, 25-year typical lifespan, slimmer sightlines now common. Aluminium: stronger, slimmer profiles, allows larger glazed areas, 35–40 year lifespan, slightly cooler thermally. Composite (alu-clad timber): timber inside for warmth and aesthetics, aluminium outside for weather, 40+ year lifespan, premium price. Timber-only: best aesthetic on period homes, requires regular paint or oil maintenance every 5–8 years.
Will replacing windows affect my BER?
Yes, meaningfully. New A-rated windows can lift BER by half a grade in a typical home — for example C2 to C1, or B3 to B2. The improvement is bigger if existing windows are pre-2005. Pair window replacement with attic insulation top-up (€500–€900) for a combined upgrade that often hits B2 in one go. A BER assessor (€150–€220) can confirm before-and-after rating.
How long does the install take?
A full 3-bed semi window replacement typically takes 2–3 days for a 2-person crew. Each window takes 60–120 minutes including removal, fitting, sealing, and reinstating sills. Disruption is moderate: rooms become cold and dusty during install. Most installers fit one room at a time so the rest of the house stays usable. Painters may need a return visit to touch up internal architrave.
