What does window replacement involve?
uPVC, aluminium and timber windows with A-rated double and triple glazing, fitted by vetted, insured local installers. SEAI-eligible in deep retrofits.
Window replacement swaps your existing windows for new ones — typically upgrading from single glazing or tired early double glazing to modern A-rated double- or triple-glazed uPVC, aluminium, or composite frames. A full replacement involves measurement, removal of the old units, fitting new frames into prepared openings, sealing for weather and air-tightness, and reinstating internal sills and architraves. A good window installer handles everything from a single misted unit to a full-house upgrade, including sash windows in period properties, bay windows, and skylights, and will advise on frame material and glazing spec for each elevation.
Modern double and triple glazing delivers significant comfort and energy improvements: noise reduction, elimination of draughts, lower heating bills, and a 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, so if a wider retrofit is on the cards it pays to plan the sequence before committing. Either way, new windows are one of the most visible upgrades a home can get — warmer rooms, quieter nights, and a better BER.

How much does 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 — treat them as a starting point rather than a fixed price, since access, floor level, and the condition of the existing openings all affect the final figure. As a rule of thumb, triple glazing costs 20–30% more than the equivalent double-glazed window.
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. Before any work starts, insist on an itemised quote that breaks out frames, glazing spec, fitting, and disposal of the old units — it makes the price easy to understand and simple to check against these ranges.
These are indicative ranges based on typical Irish jobs. Final pricing depends on scope, materials, and urgency. On Jobiit your matched trader sends one fully itemised quote (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. Ask your installer to price 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.
Will my number be passed around to multiple window companies?
No. Jobiit isn't a bidding marketplace where dozens of window companies compete for your details — your job goes to one matched trader, the closest, best-rated vetted installer covering your area, and messaging happens in-app. Every trader on Jobiit is ID-verified through Stripe Identity and holds valid public liability insurance (minimum €6.5M for most trades). Posting your job is free, and most homeowners receive a quote within a few hours.
