Our uPVC, timber and aluminium options keep your home energy efficient all year round, thanks to strong energy ratings, dense frames and low U values. Part of our wider range of energy efficient home improvements.
All of our windows use leading security hardware meeting PAS 24, with multipoint locking and internal beading as standard, and there are further options if you want more than that. Every installation is covered by a 10 year insurance backed guarantee and certified with FENSA.
Every replacement window is fully customisable, in «XX» colours and finishes with «X» handle styles, Georgian bars and leaded options. We fit systems from manufacturers including Liniar, Deceuninck and VELUX, plus our originalslimline windows
Alongside a broad choice of styles, you have real freedom in choosing your window’s material. We choose the uPVC, timber and aluminium systems we fit for their performance rather than their price list. They are exceptionally durable, thermally efficient and weather resistant. Which one is right for you usually comes down to cost, how slim you want the frame, and how much upkeep you’re prepared to take on.
uPVC, the practical choice
While uPVC may be the more cost effective option, modern advances in its production and design mean there are real benefits to it: today’s frames are more secure and more energy efficient than ever. Low maintenance too, since a damp cloth is all it asks for.
Aluminium, the slimmest frames
Aluminium is a very strong material, which makes it ideal for slimline frames and lets a great deal more natural light into a property. Like uPVC it cleans with a damp cloth, and it takes any RAL colour you like.
Timber, the period choice
Timber has long been seen as something of a premium material, given its exceptional insulation properties and aesthetic appeal. The lifespan is a strong advantage, though the maintenance takes some keeping up with, so expect to repaint every «8 to 10» years.

We have an array of high-performance glass options available with all of our windows, including double, triple and secondary glazing. From decorative to bevelled glass, you will be able to transform your property’s interior and exterior.
Simply put, double glazing has two panes of glass within a sealed unit and triple glazing has three. That extra pane improves the efficiency of any heat that would otherwise be lost, and adds a further layer of security on top of the protection a double glazed unit already gives you.
Double glazing is usually the better bet when you’re replacing old windows. The units are shallower, so they refit an existing frame without the reveal having to change, and it is the more budget friendly option, with great all round performance.
Triple glazing is warmer and harder to break through. Triple glazed units are typically wider and deeper, which makes them trickier to simply refit into an existing frame, so they suit new openings and extensions best.
Secondary glazing sits inside your existing window rather than replacing it, which makes it the answer for listed buildings and anywhere the original frames must stay.
