PROFESSIONAL INSTALLATION

PVC casement windows installed by Expert Windows

When standard-sized windows do not suit your property, Expert Windows can supply and install custom made windows in Dublin and across Ireland. Choose the dimensions, shape, material, colour, opening style and glazing that work for your space.

Our bespoke windows are available in uPVC, aluminium, timber and AluClad, with double or triple glazing. They are suitable for unusual replacement openings, older homes, extensions, new builds and architectural features.

Every unit is surveyed and specified for the property rather than selected from a limited range of standard dimensions.

How Much Do Custom Made Windows Cost?

Why Choose Expert Windows?

Custom Made Windows: Frequently Asked Questions

Windows can be manufactured in a wide range of custom sizes, but every frame and glass system has minimum and maximum dimensions. Very large panes or opening sections may require another material, added support or a revised configuration.

They can cost more than basic standard-sized windows, especially where the design includes an unusual shape, colour or glazing specification. Accurate manufacture can avoid unnecessary alterations to the existing opening.

In many cases, a new design can retain similar proportions, opening sections, colours and decorative features. The closest available match depends on the original window and chosen replacement material.

We offer made-to-measure options in uPVC, aluminium, timber and AluClad. The right material depends on the design, dimensions, appearance, maintenance requirements and budget.

Many custom window systems can accommodate triple glazing. Suitability depends on the frame system, unit size and total glass weight.

Yes. Options can include arched, circular, triangular, angled and other special-shaped windows. Some complex shapes may be available only as fixed units.

Yes. Older properties often require made-to-measure windows because openings vary in size. Protected structures or conservation areas may require approval before materials, proportions or appearance are changed.

Lead times depend on the material, colour, glass and complexity. Special shapes and non-standard finishes can take longer than conventional rectangular windows. We provide an expected timeframe with the quotation.

Approximate measurements and photographs are useful for an initial enquiry, but final manufacturing dimensions should be confirmed through an appropriate survey.
