Choosing Doors for Your Irish Home

Replacing every door in an Irish home is one of the highest-return improvements you can make — it lifts kerb appeal, cuts heating bills, improves security, and (with the SEAI grant) recovers a significant chunk of the cost. But there is no single right answer for every doorway. The front, back, kitchen-to-garden and any side-access doors each have different jobs to do, and the right spec varies by opening.

After 23 years installing across Dublin, Kildare and Wicklow, this is the framework we walk every customer through. Indicative all-in cost for a typical 3-bed semi-detached door package in 2026: €3,500 – €5,500 + VAT, with up to €800 per door back via the SEAI Better Energy Homes grant.

Start With the Job Each Door Does

Different doors have different priorities:

• Front door — security, kerb appeal, thermal performance, in that order. This is the door buyers and neighbours see; it sets the perceived value of the home.
• Back door — security and thermal performance. Kerb appeal matters less because the door is not street-visible. uPVC works well here.
• Kitchen-to-garden door — natural light and opening width. French or sliding patio doors, depending on the rear opening size.
• Side / utility / passage doors — security and weather resistance. Plain uPVC is fine; nobody sees them from the kerb.

The Front Door: Where Composite Wins

For the front door, composite doors in Dublin beat every other option on Irish housing stock. The solid 44 mm timber core resists forced entry far better than the hollow chambered uPVC slab. The U-value (around 1.0 W/m²K) is ~30% better than uPVC. The GRP outer skin holds its colour for 35+ years and doesn’t chalk or peel.

• Typical fitted cost: €1,800 – €2,400 + VAT
• SEAI grant: up to €800 per door on A-rated upgrade
• Lifespan: 35+ years

The Back Door: Where uPVC Pays Off

For the back door, a quality uPVC unit is the right answer in roughly 70% of Dublin homes. A 28 mm chambered uPVC slab with steel reinforcement, half-pane or full-pane laminated glass, multi-point locking, fitted into a uPVC frame — maintenance-free, A-rated thermal performance, and still qualifying for the SEAI grant.

• Typical fitted cost: €1,170 – €1,400 + VAT
• Lifespan: 20–25 years
• Best for: Utility-to-garden, kitchen back doors where the door is not street-visible

Move up to composite if the back door is street-visible (corner site, terraced row backing onto a road) or if you’re matching a composite front. For the six different back-door styles available, see Back Door Types Compared.

The Kitchen-to-Garden Door: French or Sliding?

The most-discussed decision in any whole-home door upgrade. Short answer:

• Opening width 1.5 – 2.0 m: French doors (€2,400 – €3,200 + VAT)
• Opening width 2.0 m+: Sliding patio doors (€2,800 – €4,500 + VAT, uPVC)
• Opening width 3.0 m+ in an extension: Aluminium lift-and-slide doors (€4,000 – €11,500 + VAT)

Security: One Standard Across Every Door

Every external door we fit in 2026 ships with multi-point locking (3-point minimum, 5-point typical on composite and sliding), TS 007 3-star anti-snap euro cylinder, laminated glass on any glazed section, reinforced hinges or anti-lift blocks, and PAS 24 / Secured by Design certification. This is no longer a premium upgrade — it’s the floor. Irish insurers increasingly check for it on renewal. See our secure windows & doors page for the full security spec.

SEAI Grant: Up to €800 Per Door

SEAI Better Energy Homes pays up to €800 per A-rated external door in 2026. Composite, A-rated uPVC, French and sliding doors all hit the threshold (U-value ≤1.4 W/m²K) as standard. The grant is paid directly to you after install and BER inspection. Airtight is an SEAI-registered installer — required for your upgrade to qualify. See the SEAI grant page for the full process.
