The range

Composite door styles we manufacture

Every door is made to measure. Explore the range, then book a free survey for an accurate, itemised quote.

Composite front doors

Front door replacement is the bulk of what we make: a solid core, a moulded skin and a reinforced frame, built for the face of the house.

Composite back doors

Composite back doors in the same build as the front, usually with obscure glass and a simpler panel design.

Cottage style

A cottage style composite door with the ledged and braced look, suited to older stone and brick frontages.

Contemporary

A contemporary composite door with long glazed strips or a plain slab, matched to modern render and grey frames.

With side panels

A composite door with side panel or a top light, where the opening is wider than a single leaf.

Stable and French

A composite stable door for kitchens and utilities, and composite french doors where the opening takes two leaves.

Construction

What is inside a composite door

The core is what separates a composite door from a plastic one, and it is the part you cannot see on a showroom floor.

GRP composite door

A GRP composite door uses a glass reinforced plastic skin over an insulating core. Tough, low maintenance and the most common build.

Timber core

A timber core composite door has a solid engineered hardwood core, so it is heavier, stiffer and closer to a real timber door in feel.

Solidor

Solidor composite doors are the best known timber core brand, and the usual reference point when people compare door slabs.

Energy performance

An energy efficient front door and A rated composite door build, because a door is a large hole in an insulated wall.

Colour & glass

Colours and glass designs

The colour is part of the skin rather than a coat of paint on top, so it does not flake and does not need redoing.

Anthracite and black

An anthracite grey composite door or a black composite door, the two finishes that now outsell everything else, usually alongside grey windows.

Traditional colours

A blue composite door, green composite door or red composite door, still the right answer on a period frontage.

Full colour range

Composite door colours across the standard palette, with different colours inside and out where the hallway needs something lighter.

Glass designs

Composite door glass designs from plain obscure to leaded and stained patterns, in toughened safety glass as the regulations require.

With glass or without

A composite door with glass for a hallway that needs the daylight, or a solid slab where privacy and security matter more.

Hardware

Composite door furniture in matching or contrasting finishes: handles, letter plates, knockers, numerals and a spy hole.

Security

The security specification

A solid slab is only as strong as the lock in it. Almost every forced front door in Manchester is a snapped cylinder rather than a broken door.

PAS 24

A PAS 24 composite door is tested against the standard attack methods rather than just described as secure. We build to it on request.

Secured by Design

A Secured by Design door meets the police preferred specification, which some insurers and most new build warranties ask for.

Anti snap cylinders

An anti snap lock composite door is our default fit, not an upgrade. A basic cylinder is the single weakest part of any front door.

Insurance approved

An insurance approved front door specification, documented on the invoice so you have evidence if you ever need to claim.

The most secure option

Asked for the most secure front door, we specify a timber core slab, a three star cylinder and laminated glass rather than toughened.

Repairs too

We also repair composite doors, so if yours has dropped or the gearbox has failed, that is a repair rather than a new door.

Already have a composite door that will not lock? See door repairs rather than replacing it.

Composite door questions

How much does a composite door cost fitted in the UK?

Price follows the door slab, the glass design, the colour and the hardware rather than a single figure. A plain slab in a standard colour with obscure glass is the cheapest thing we make; a timber core door with a decorative glass panel and a side light is the dearest. Because we manufacture rather than resell, there is no distributor margin in the quote.

How long do composite doors last?

The slab itself is a long term item. What ages first is the hardware: the multipoint gearbox, the hinges and the cylinder, all of which we repair rather than replace the door. A composite door that is adjusted once or twice in its life will outlast the uPVC door it replaced.

Composite vs uPVC door, which is better?

A composite door has a solid core, so it is heavier, stiffer and better insulated than a hollow uPVC slab. It also holds its colour and does not flex in the heat the way uPVC can. uPVC costs less. For a front door on the street face, composite is usually the better buy; for a back door in a sheltered spot, uPVC is often enough.

Are composite doors secure?

The slab is the strong part, and the lock is the weak one. A composite door with a basic cylinder is no safer than any other door, because lock snapping bypasses the slab entirely. Ours are fitted with anti snap cylinders as standard and can be specified to PAS 24.

Can composite doors be painted?

They can, but they should not need to be. The colour is part of the skin rather than a coat on top, so it does not flake or need redoing. Painting over it means committing to repainting it from then on.

Do composite doors fade?

Darker colours take more sun than lighter ones, and a south facing door will always weather faster than a north facing one. Modern skins hold colour well, and fading is gradual rather than patchy. It is one reason anthracite and black have replaced the older reds and blues on exposed frontages.

How long does it take to fit a composite door?

Fitting is half a day for a straightforward swap into an existing frame, longer where the opening has to be altered or a side panel is involved. The manufacturing time before that is the longer part, and we confirm it when the order is placed.

Door damaged, or a lock that will not turn?

Our 24/7 emergency team secures and repairs doors across Greater Manchester, with parts and glass from the same workshop.

Judging a door

What actually makes a composite door secure

The slab is the part everyone looks at and the part that matters least. Almost every forced entry through a composite door is an attack on something else.

The cylinder
Three star, anti-snap, anti-bump, anti-drill. Cylinder snapping is the single most common method of forcing a composite door, and a good cylinder is not expensive.
The mechanism
Hooks as well as bolts, and how many locking points engage down the length of the door.
The hinges
Whether they carry security studs that hold the door in the frame even if the hinge pins go.
The frame and its fixings
A good door is only ever as secure as what it is screwed into.
The glass in any panel
Laminated, particularly in a panel within arm's reach of the handle.

PAS 24 is the standard worth asking about by name. If a quote does not mention it, ask why.

Straight answer on cost

What changes the price of a composite door

A composite door is priced as a complete unit: slab, frame, glass and hardware.

  • Style and colour. Solid colours are standard, and some finishes and dual colours cost more.
  • Glazing. A plain solid door is the base. Decorative or triple glazed panels add to it.
  • Lock specification. An anti-snap, three-star cylinder and the mechanism behind it are what your insurer cares about.
  • Frame and side panels. A new frame and threshold, or a side light, changes the size of the job.
