How much do new doors cost in Teesside? (2026)

Why the fitted price is the only price that matters

Door adverts love a supply-only number: a composite door for £595, a bi-fold for £1,800. That is the product in a warehouse, before the frame, the hardware, the cylinder, the survey, the fitting, the making good, the disposal of the old door and the guarantee. By the time an honest installer has added those, real Teesside prices land where the table above puts them, and anyone quoting dramatically below those ranges is omitting something you will pay for later, in cash or in a door that never quite closes right.

The fitted price buys the whole job: measured survey, made-to-measure door and frame, security hardware, sealed and trimmed installation, old door taken away, and a written guarantee, ten years being the industry norm on external doors.

What moves the price on external doors

Material

The biggest single decision. uPVC at £650 to £950 is the budget workhorse. Composite at £1,000 to £1,700 buys a solid core, better security and a maintenance-free finish that outlasts uPVC. Aluminium at £1,800 to £3,000 buys slim sightlines and contemporary design. The materials guide is the full comparison.

Glass

A solid door is the cheapest option; plain double-glazed units add modestly; decorative, bevelled or sandblasted designs add £100 to £300. Glazed side panels add £400 to £500 each within a combined frame. On patio doors and bi-folds, solar-control glass for south-facing rooms adds roughly 10 to 15 percent to the glass cost.

Colour and finish

Stock colours are usually included. Foiled colours on uPVC add £100 to £200; dual colours on composite add £50 to £150; custom RAL colours on aluminium add more and lengthen lead times. Coastal properties should budget for marine-grade hardware, a modest sum that saves fittings corroding within two winters.

Security hardware

The one upgrade never worth skipping: a TS007 3-star anti-snap cylinder, which should appear in the quote by name. Beyond that, heritage handle suites and architectural stainless hardware add £50 to £200 where the look matters.

The opening

A like-for-like swap into a sound opening is the base price. Out-of-square period openings, rotten subframes, failed lintels and window-to-door conversions all add making-good work, itemised separately in a proper quote. Creating a new opening for bi-folds adds lintel or steelwork costs that vary with the span and the wall construction.

Bi-folds and patio doors: pricing by the opening

Garden doors are priced by size and panel count rather than as a single product. French doors cover standard 1.2 to 1.8 metre openings at £1,400 to £2,400. Two-pane sliders cover 1.5 to 2.4 metres at £1,600 to £2,800. Bi-folds start at £2,800 for three panels and add £500 to £800 per panel, so the honest comparison across a 3 metre opening is roughly £2,000 for a slider against £3,500 for a four-panel bi-fold, buying you the full opening against half of it.

Internal doors: pricing by the set

Per door, £120 to £250 hung with furniture. The meaningful saving is in the set: eight to ten doors typically cost £1,200 to £2,000 all-in, because the per-visit costs are shared. Primed doors for painting are cheapest, white pre-finished panels sit in the middle, and oak veneer or glazed designs top the range. New architraves, where wanted, add £40 to £70 per door.

How to judge a quote

Four tests. Is it itemised, with the door, frame, glass, hardware, cylinder grade and making good spelled out? Is the product named, manufacturer and style, rather than "composite door"? Is the cylinder grade stated? And is the guarantee in writing with a term? A quote that passes all four can be compared fairly against another that does. A single-line cash price cannot.
