What Are Casement Windows?

A casement window is hinged on one side and opens outward on a simple lever or handle, a bit like a door swinging open. It’s the style most of us grew up with, and it’s stayed popular because it’s hard to fault: no complicated mechanism, just a window that opens, closes and locks properly.

They come in a few configurations:

  • Side-hung – hinged down one edge, opening outward like a door, the most common type
  • Top-hung – hinged along the top, handy above a kitchen sink or worktop where you don’t want it swinging into your space
  • Fixed panels – don’t open at all, useful for extra light without ventilation, often paired with opening casements

Most are uPVC or aluminium, though timber-look and flush sash options give a traditional look without the upkeep of real wood.

Why Choose Casement Windows for Your Home?

Maximum Natural Light

Casement windows tend to have slimmer frames than a lot of other window styles, which means more glass and less frame per window. That translates to more daylight getting into the room, which matters more than people expect, especially in older properties where rooms can feel a bit gloomy to begin with.

Excellent Ventilation

Because the whole sash swings open, casement windows can catch a decent amount of airflow, sometimes even directing a breeze into the room depending on which way it’s facing. Open it a crack for background ventilation, or push it right out on a warm day, it’s entirely up to you.

Strong Thermal Efficiency

When a casement window closes, the sash presses firmly against the frame all the way round, which creates a tight, consistent seal. Combined with A-rated double or triple glazing, this helps keep the heat in during winter and out during summer, and it should show up on your energy bills over time.

High Security as Standard

Modern casement windows lock at multiple points around the frame rather than relying on a single latch, and most come with reinforced hinges and shootbolt locking as standard. It’s a big step up from the windows a lot of older South London and Surrey homes were originally built with.

Low Maintenance

uPVC and aluminium casement windows don’t need repainting, don’t rot, and don’t warp with the seasons the way timber can. A wipe down now and then is really all they ask for.

Wide Range of Styles

From plain, minimal frames to sculptured, traditional profiles with glazing bars, casement windows can be dressed up or down to suit whatever the property calls for. There’s a genuinely wide choice of colours and finishes too, so matching your existing exterior isn’t a problem.

Our Casement Window Materials

uPVC Casement Windows

uPVC Casement Windows

This window frame type remains the most popular one, and there is no difficulty understanding why. uPVC casement windows are inexpensive, have a high level of thermal insulation, are low maintenance, and do not require any further modifications. This product comes in white, anthracite grey, black, and wood grain colors.

Aluminium Casement Windows

Aluminium Casement Windows

If you’re after something sleeker, aluminium casement windows give you slimmer sightlines and larger panes of glass, which means more light and a more contemporary look. Aluminium is naturally strong, resists corrosion well, and comes in a broad range of RAL colours, anthracite and bronze being particularly popular across South London and Surrey right now.

Casement Windows for Different Property Types

Period and Character Homes

South London and Surrey have plenty of Victorian, Edwardian and Georgian properties, and casement windows can be finished with sculptured profiles, glazing bars and timber-effect foils to sit comfortably alongside original features without looking out of place.

New Build and Modern Properties

For newer homes and contemporary renovations, slimline or flush casement windows give a clean, architectural finish that suits larger glazed areas and open-plan interiors.

Extensions, Conservatories and Loft Conversions

Casement windows are a common choice for extensions and conversions, where fixed and opening panels can be combined to maximise light while still giving you control over ventilation exactly where you need it.

Bay and Bow Window Configurations

Several casement windows can be joined together to form a bay or bow window, a popular option for front-facing rooms across South London and Surrey, adding extra floor space, light and kerb appeal in one go.

Casement Window Replacement in South London and Surrey

If your current windows are draughty, sticking, rotting at the joints, or just past their best, replacing them with new casement windows is one of the more worthwhile upgrades you can make. We strip out the old frames, make good the surrounding brickwork, plaster and sills, and leave everything clean and tidy once the new windows are fitted.

We handle everything from a single replacement window to a full-house re-glaze, and there’s no obligation to stick with one style throughout, plenty of our customers mix casement windows with other styles depending on the room.
