uPVC Casement Windows in South London and Surrey

Glitz Windows & Doors supplies, fits and repairs uPVC casement windows for homes across South London and Surrey. We’re a family-run firm based in Coulsdon with more than 25 years’ experience and we handle every stage ourselves, from the free survey to the certificate at the end.

A casement is hinged at the side or top and opens outwards, like a small door. It’s one of the most common replacement styles in the UK because it’s simple to use, keeps the weather out and is usually good value. Whether you need one window, the whole house or a repair to what you already have, you’ll get a clear written price after a free survey.

Why Choose Casement uPVC Windows?

  • Simple to use. One handle and a stay, with no settings to learn.
  • Warm and draught-free. Multi-chambered frames, efficient double glazing and tight seals cut heat loss and meet Part L of the Building Regulations.
  • Secure. Multi-point locking holds the sash firmly in the frame and our installations meet Part Q for security.
  • Low upkeep. No sanding or repainting. Soapy water keeps them looking new.

Because casements open outwards, we’ll check clearances near paths and balconies before recommending a layout.

uPVC Casement Window Styles and Finishes

Every window is made to order, so you choose the look. If you're comparing a uPVC window casement with sash or tilt and turn, casements are usually the most versatile option.

Standard or flush.

On a standard casement, the sash sits slightly proud of the frame. A flush casement sits level, giving a neater, timber-style look that suits period homes. Flush usually costs a little more.

Layouts.

Side-hung and top-hung openers, fixed panes, French casements (a pair of sashes opening from the middle) and bay or bow windows can all be combined.

Period homes and conservation areas.

uPVC isn't automatically ruled out, but rules vary by council and listed buildings are stricter. Check with your local planning authority and we'll talk through heritage-style options at your survey. Bring photos and we'll show you samples.

uPVC Casement Windows Fitting & Repair

Not every tired window needs replacing. We can usually fix loose or broken handles and locks, worn hinges that make the sash drop, perished seals and draughts, stays that won’t hold and misted units, where we fit a new sealed unit in your existing frame.

If the frames are cracked, warped or very old or several windows are failing at once, we’ll say so and talk through replacement. A repair that only buys you a year isn’t worth your money.

uPVC Casement Windows Cost

The cost of uPVC casement windows depends on your home, so we don’t publish a one-size-fits-all figure. The main things that affect it are:

  • the size and number of windows
  • the glazing you choose
  • colour and finish, including woodgrain
  • lipped or flush styles
  • access, such as upper floors or scaffolding

The easiest way to get a real answer is a free survey and a detailed written quote. Customers often tell us they liked the fair, pressure-free assessment and not being sold extras they didn’t need.
