How much is a composite back door fitted in Teesside?

£950 to £1,500 supplied and fitted for a standard opening. Half-glazed styles sit mid-range; fully glazed and non-standard sizes cost a little more.

Can I have a cat flap in a composite door?

Yes, but have it factory-fitted when the door is made. The panel arrives reinforced and sealed; cutting a flap into a finished composite door risks the guarantee.

Is a composite back door as secure as a front door?

It should be, and any quote here specifies it that way: the same multi-point locking, the same anti-snap cylinder, the same PAS 24 construction. Back doors are the more common entry point for burglars, so this is not the place to economise.

Half-glazed or fully glazed for a kitchen?

Half-glazed suits most kitchens: light where you want it, solid where the wear is. Fully glazed earns its keep in dark, north-facing rooms where every bit of daylight counts.

How long does fitting take?

A straight swap takes 2 to 3 hours. The kitchen is back in use the same day.

Composite back doors in Teesside

A composite back door, supplied and fitted, costs £950 to £1,500 on Teesside in 2026. The most popular choice is a half-glazed style that brings light into the kitchen while keeping the bottom half solid, with the same multi-point locking and weatherproof GRP skin as a front door.

The most-used door in the house

The back door works harder than the front: bins, bikes, pets, kids, and every trip to the garden, hundreds of times a week. It is also the door most likely to be the house's weak point, both thermally and for security, because older back doors are often thin timber or early uPVC with a single-point lock fitted as an afterthought.

A composite back door fixes both at once. The solid core and compression seals end the kitchen draught, the GRP skin shrugs off muddy paws and footballs, and the multi-point lock brings the rear of the house up to the same standard as the front. Insurers increasingly ask about back door locks specifically, and a PAS 24 composite door with a 3-star cylinder answers the question.

What they cost on Teesside

Expect £950 to £1,500 supplied and fitted. Back doors are usually a touch cheaper than front doors because the styling is simpler and the furniture more functional. Half-glazed designs sit mid-range; fully glazed doors and stable-door conversions cost more. If the opening needs widening or the old frame has rotted into the brickwork, the quote will itemise the making good separately.

Choosing the glazing

Half-glazed: the classic kitchen door. Light in at eye level, solid below where kicks and paws land. The most-fitted back door on Teesside.
Fully glazed: maximum light for north-facing kitchens, with obscured backing glass if the door faces a neighbour or a shared path.
Solid: for utility rooms and doors where privacy or security outweighs daylight.
Stable split: the back door that opens in two halves, covered on the stable doors page.

Cat flaps, dog flaps and practical extras

Pet flaps can be factory-fitted into the door during manufacture, which is far better than cutting one in later: the panel is reinforced, sealed and guaranteed. Say so at the quote stage if you want one, because retrofitting into a composite door is a specialist job. Other practical extras worth asking for: a mid-height letterbox-style knocker omitted (nobody uses one on a back door), lever handles rather than knobs for muddy hands, and a low aluminium threshold if anyone in the house uses wheels of any kind.

Back door vs French doors

If the back wall of the kitchen is mostly door and window, it is worth pricing both options. A pair of composite French doors costs £1,500 to £2,400 and transforms how the kitchen connects to the garden, which is why so many Teesside kitchen refits now include swapping the back door and adjacent window for French doors. The cost guide covers both routes.
