Flush casement windows have a clean, flat profile that sits neatly within the frame rather than sitting on top of it, giving a smart, contemporary look that still suits a period home just as well as a modern one. The chamfered lines and subtly sculpted edges give them a quality feel from both inside and out, whether the sash is open or closed.
Sheerwater Glass has been fitting windows and doors across Surrey since 1972, and we offer flush casement windows in aluminium, uPVC and timber, so whichever material suits your home and budget, we’ve got you covered. Aluminium is our most popular choice for anyone after a slim, low-maintenance frame that’s built to last.
The first thing people notice about a flush casement window is what’s missing. There’s no window sitting proud of the frame, just clean, chamfered lines and a flat surface that sits neatly within it. It’s a subtle design choice that makes a genuine difference to how a house looks from the street, whether it’s a period cottage or a new build.
Aluminium is what makes that slim, flush profile possible. It’s strong for its weight, doesn’t absorb moisture, and won’t warp or rot the way some other materials can over time. Whatever the Surrey weather throws at it, an aluminium flush casement window is built to cope with it and keep looking the way it did on day one.
There’s plenty of room to make it your own too. Choose from plain, etched or stained glass, or add leaded lights for a more traditional feel. Georgian bars and weather bars are both available if you want to add extra character or weather protection, and there’s a choice of traditional peg stays or monkey-tail handles to finish the look.
Aluminium doesn’t absorb moisture, so it won’t warp, rot or corrode the way other materials can over time. It copes with everything the Surrey weather throws at it and keeps its shape and finish for years to come.
There’s no repainting or resealing to think about. A quick wipe down is usually all it takes to keep an aluminium flush casement window looking as good as the day it was fitted.
Choose from white gloss, anthracite grey matt, black matt or any RAL colour you like, in plain, etched or stained glass, with leaded lights, Georgian bars or weather bars if you want to add character. There’s a good chance we can get it looking exactly how you pictured it.
Flush casement windows have a long history in British homes, and that classic look hasn’t gone out of style. If your house has real character, whether that’s a period cottage or a Victorian terrace, they’re a natural fit that keeps the traditional lines you’d expect.
The difference is what’s happening behind that traditional look. Aluminium brings the durability and low maintenance of a modern material, so you get the appearance of the past without the upkeep that used to come with it. It works just as well in a new build looking to soften its lines as it does in a period home staying true to its roots.
“From the initial visit to the showroom through to the installation of the front door I cannot fault the professionalism and service I received. The installation guys cleared up after themselves and explained very clearly how the door works. I wouldn’t hesitate to recommend Sheerwater Glass.”
If aluminium isn’t quite right for your project, we also fit flush casement windows in uPVC and timber, so you can pick the material that suits your home and budget best. Get in touch and we’ll help you find the right fit.
