A larger front door? No problem.

Unlike composite front doors, which can be restricted when it comes to larger sizes, our Residence Collection uPVC front door can be made to fit your doorway perfectly, up to 900mm wide by 2200mm high.

So, if you have a larger entrance, you don’t have to compromise on the proportions or settle for a door that doesn’t look quite right.

With an authentic wood-effect finish and a choice of designs, colours, glazing and hardware, you can create a front door that is made for your home.

Your own design, in a size that fits.

The leading brands - expertly fitted.

Why? Because they are simply exceptional.

Available in a choice of styles, configurations and finishes, they look equally stunning in contemporary, traditional and period properties.

When internal doors look this beautiful and perform this well, we don’t believe we need to offer anything else!

Whether you're off on holiday, enjoying a day trip out or making the most of the long summer evenings out with friends, it's easy to wonder...

"Did I lock the front door?"

With every Comp Door composite door supplied and installed by us, Kubu Smart technology comes included as standard and AT NO EXTRA COST, giving you extra reassurance wherever summer takes you.

Using the free Kubu app, you can check whether your door is open, closed or locked from wherever you are. Kubu keeps you informed with instant notifications, giving you added confidence and peace of mind. You can even receive alerts when family members arrive home safely.

Unlike many smart home systems, Kubu doesn't unlock your door remotely, ensuring your home's security is never compromised while still giving you the convenience of smart monitoring.

Combined with Comp Door's solid timber core and exceptional thermal performance this industry-leading security is another reason why Comp Door is one of the UK's most advanced composite doors.

Introducing the new Aluco DUPLEX LOCK, an innovative feature that takes the authenticity of Aluco steel-look (aluminium) windows to an entirely new level.

Using a single handle to operate two locking points, it delivers elegant functionality while enhancing the distinctive steel-look aesthetic that makes our Aluco windows so desirable.

Available in a range of period-inspired finishes including Antique Brass and Bronze, the Duplex Lock is more than just window hardware. It's a carefully engineered design feature that perfectly captures the character of classic steel windows without the cost, maintenance or limitations of steel.
