Three common scenarios — each has different pricing, lead times and SEAI grant eligibility. We cover all three.
The most common project. Typical 3-bed semi: 8–10 windows + composite front door + uPVC back door, fitted in 2–3 days. Up to €4,600 SEAI grant on a semi-detached, €5,600 on a detached.
Working with an architect or builder? We work directly with their drawings — they send us the schedule of windows and doors, we quote off it. Most-popular spec: sliding patio doors on the rear extension + replacement windows on the original house.
Working with your architect from the start. We supply for the whole envelope: front door, back door, all bedroom + reception + utility windows, kitchen-to-garden door. Custom spec (RAL colours, triple glazing, aluclad available) on every product.
All A-rated, all SEAI-eligible, all custom-manufactured to your opening. Tap any style for full spec + pricing.
From €800 SEAI grant per external door (max 2). Composite, uPVC, French and sliding — all eligible.
A-rated U-values 0.8–1.4 W/m²K. Old single-glazed or drafty 1990s units lose massive heat through the frame and seal.
Standalone grant since 2024. Detached €4,000 windows + €1,600 doors. We're an SEAI registered installer.
New A-rated windows + composite front door measurably lift property value in Dublin estate-agent listings.
TS 007 anti-snap cylinders, laminated glass, 5–10 locking points. Insurers ask for it on renewal.
The SEAI Better Energy Homes grant pays up to €4,000 for windows + €1,600 for doors on a detached home — paid directly into your bank account after install and post-works BER.
We’re an SEAI registered installer, which is required. Our registration number goes on every quote.
