One of the most common questions we get before a site survey is simple: how much will this actually cost? It is a fair question, and one that is hard to answer honestly with a single number, because window pricing depends on frame material, size, glazing, hardware and the condition of the existing opening. What we can do is give Galway homeowners realistic ranges to plan around, and explain what moves a quote up or down.
Why there is no single price per window
Two houses on the same estate can get very different quotes for what looks like "the same job." A standard-sized casement window in a straightforward opening is a different job to a large picture window, a bay configuration, or a frame that needs to be built into an opening with uneven plaster or old, out-of-square timber. Access, scaffolding, disposal of old frames and the amount of finishing (internal scotia, external render repair) all factor in too. Treat any price guide, including this one, as a starting point for a conversation, not a fixed quote.
Typical price ranges by frame material
As a rough guide for a standard-sized uPVC casement window, supplied and fitted, homeowners in Galway are typically looking at a range from the low hundreds up through the mid-hundreds of euro per window, with the final figure depending on size, opening configuration and hardware. Larger windows, tilt-and-turn mechanisms, or non-standard shapes push this upward.
Aluminium windows generally sit above uPVC for an equivalent size, reflecting the cost of the material and the thermal break construction needed to perform well. The gap tends to be more noticeable on larger openings, where aluminium's slimmer frames and structural strength come into their own — sliding doors, bi-folds and large fixed panes are where aluminium is often chosen despite the higher cost.
Aluclad sits at the top of the three, combining a timber inner frame with an aluminium external skin. The additional materials and construction complexity are reflected in the price, and aluclad is usually specified for period properties, self-builds or renovations where the look and feel matter as much as performance.
What changes the price beyond the frame material
A few factors consistently move a quote, regardless of material:
- Glazing: triple glazing costs more than double glazing per unit, but can reduce heating costs and improve comfort in exposed or north-facing rooms.
- Size and shape: large, tall or non-standard shaped windows (arched, bay, corner) cost more than standard rectangular openings of similar area.
- Number of openers: fixed panes are cheaper than opening sashes; tilt-and-turn hardware adds cost over a simple casement.
- Access and site conditions: upper floors, tight access, or the need for scaffolding add to the fitting cost.
- Condition of the existing opening: rot, damp or out-of-square openings found once old frames are removed can add unexpected work, which is why a proper survey matters before a firm price is given.
- Colour and finish: woodgrain foils, dual-colour frames (different inside and outside) and non-standard RAL colours typically cost more than standard white or anthracite.
Whole-house upgrades versus single windows
Replacing all the windows in a house at once is usually more cost-effective per window than doing them one or two at a time over several years, since site setup, scaffolding (if needed) and waste removal are shared across the job. If budget is the constraint, a phased approach — starting with the worst-performing or most exposed windows, often north- and west-facing rooms in Galway's weather — is a reasonable way to spread the cost while still making a real difference to comfort.
Getting an accurate quote
Rough dimensions, the number of windows, and photos are usually enough to start a conversation and get a ballpark figure. A firm quote should follow a site survey, where actual openings, access and condition are checked. Be wary of quotes given without any site visit or photos at all — they tend to either overshoot to cover risk, or undershoot and get revised upward once work starts.
If you are planning a window replacement project in Galway City or County and want a realistic price range for your home, request a quote with a few details about the property, or get in touch if you would like to talk through the options first.
