| Sliding patio door | €2,000 | €4,500 | Size, material |
Window costs depend on four main factors: the frame material (uPVC is cheapest, timber is most expensive), the glazing specification (double vs triple, low-E coatings, argon fill), the number and size of windows, and whether structural work is needed (widening or narrowing openings). A full replacement of all windows in a typical three-bed semi costs €5,000 to €8,000 in uPVC and €10,000 to €18,000 in aluminium. Front doors range from €1,500 to €4,000 depending on material and security specification. Dublin prices are typically 15-20% above the national average.

uPVC is the most popular choice in Ireland: it is affordable, low-maintenance, energy-efficient, and available in a wide range of colours and woodgrain finishes. Aluminium suits contemporary and modern homes with its slimmer profiles and clean lines, and is increasingly popular for extensions and large glass features. Timber is the traditional choice for period properties and conservation areas, offering an authentic appearance but requiring regular painting or staining every 5 to 8 years.
Yes. Upgrading from single glazing to A-rated double glazing can improve your BER by 1 to 2 grades. Upgrading from older double glazing to modern A-rated or triple-glazed units also makes a measurable difference, though less dramatic. The improvement depends on your home's other features. Your BER assessor can estimate the impact before you commit.
Double glazing (two panes with an argon-filled gap) is the standard choice and provides excellent energy performance at a reasonable cost. Triple glazing (three panes, two argon gaps) offers superior insulation and noise reduction but costs 20-30% more. Triple glazing is most worthwhile in exposed locations (coastal or elevated sites), very noisy areas, or as part of a deep retrofit aiming for an A-rated BER. For most Irish homes, A-rated double glazing is the best value.
For most houses, no. Window replacement is generally exempt from planning permission provided you are replacing like with like (same openings, similar appearance). However, if your home is a protected structure or in an Architectural Conservation Area, you may need permission, and there may be restrictions on materials, profiles, and colours. Changing window sizes or adding new openings always requires planning permission regardless of location.
uPVC windows typically last 20 to 30 years. The sealed glazing units may need replacing after 15 to 20 years if the seal fails and condensation appears between the panes. Aluminium windows can last 30 to 50 years with minimal maintenance. Timber windows, if well-maintained (painted every 5 to 8 years), can last 50 years or more. The weakest point is usually the sealed glass unit rather than the frame.
