Two styles
Rockdoor Classic and Vogue, both made as French doors, both quoted at one all-inclusive price.
Our composite French doors are Rockdoor doors: a high-density foam core, an aluminium-reinforced frame, Winkhaus multi-point locking and S-Glaze sealed glass. Rockdoor makes most of its styles as French doors; two of the styles we have fitted are shown here.

From £3,650 fitted
A traditional pair, with a tall pane of glass above a moulded lower panel. We have fitted it in White and in Rosewood, some with slim sidelights or small flag windows.

From £3,400 fitted
A cleaner, more modern pair, with slim upright panes of glass in a flat slab. We have fitted it in Agate Grey with a matching outside frame, and in White.
Both come with a 10-year manufacturer’s guarantee. Not sure which suits your opening? Send us a photo of your existing doors and we’ll design and price a pair.
Multi-point locking holds the pair shut at several points, and the frames are reinforced. That is a lot more to get past than an old timber or uPVC pair.
An insulating foam core, double glazing and weatherproof seals cut draughts and heat loss, even across a big glazed opening.
Timber French doors swell, rot and stop sealing well. A composite pair keeps its shape and its seal.
No painting, varnishing or treating. A wipe with soapy water keeps the doors clean.

Very Secure Doors recently fitted French doors in our lounge and a new front door. We cannot speak too highly of them. The quality of work was superb and they were a pleasure to deal with throughout. Their price was extremely good value for money compared to other quotes we had received. We wouldn't have the slightest hesitation in recommending them to anyone needing new doors.
Another great installation by Jim and Very Secure Doors this week. They installed several doors at my last property and when I moved house recently and the new place needed doors I didn't hesitate to get this great company to fit two sets of Rockdoor French doors, side panels, a Rockdoor back door and also to fit my own supplied steel security fire door for me. Just like last time, getting a quote was easy, site survey on time and three days of fitting this week with no mess and an attention to detail that you only get from the very best installers. Its the little touches that make such a difference and these guys go out of their way to do a first class job. Really happy repeat customer, I wouldn't hesitate to recommend them.
Common questions
Tap a question to see the answer.
A pair of Rockdoor composite French doors starts from £3,400 fitted, including VAT. Sidelights, colour, glass and hardware make up the rest, and the price on your emailed quote is the price you pay. See our composite door prices guide.
Yes. They have multi-point locking and an anti-snap cylinder, and the frames are reinforced. The glass is sealed into each door with S-Glaze rather than clipped in, and laminated glass is available if you want more protection.
Composite doors are thicker and heavier than uPVC, so they are harder to force, and they hold their shape and their seal. uPVC can warp and discolour over time. Our French doors are made to measure for your opening.
Yes. An insulating foam core, double glazing and weatherproof seals cut draughts and heat loss, and they seal better than old timber doors, which swell and stop closing well. Rockdoor rates the Classic B, as it does other styles with big panes of glass.
The lock. French doors have a lock on each door, so both open easily onto a patio, and both have lever handles. A double door opens on one key, with finger bolts holding the second door shut, and can have a bar handle on each door. We fit both.
Any of Rockdoor’s 14 colours, and the inside can differ from the outside. We have fitted French doors in White, Agate Grey and Rosewood. See Rockdoor colours.
Yes. A sidelight on each side lets in more light and suits a wider opening. Each panel typically adds £300–£500 to the price.
French doors suit a standard opening and give you a secure pair. If you want a much wider opening that folds right back, look at our aluminium bifold doors.
Expect around seven weeks from order to fitting. We quote within 24 hours, then measure the opening carefully, because a pair has to fit it exactly.
Yes. If you are outside our area or have your own fitter, we can supply composite French doors for delivery across mainland UK. Get in touch for a supply-only quote.
