Looking for a wide opening to the garden? We also supply and fit aluminium bifold doors.
Two ranges
Rockdoor and GRP, both fully fitted by Jim and Josh, at one all-inclusive price.
Rockdoor and GRP: our two composite door ranges
Every door we fit is a true composite: a hard-wearing skin over an insulating foam core, in a reinforced frame with multi-point locking. What differs between our two ranges is the security specification, the choice of styles and the price.
From £1,900 fitted
Rockdoor composite doors
The most secure composite door we fit. Made to measure in Lancashire around an aluminium-reinforced frame, with S-Glaze glass sealed into the door so it can’t be removed from outside.
Winkhaus multi-point locking and a 3-star anti-snap cylinder
PAS 24 certified, with a Secured by Design option
Over 25 styles in 14 colours, plus exclusive 3D glass designs
A woodgrain skin of glass-reinforced plastic over an insulating foam core, in a steel-reinforced uPVC frame. It won’t rot, flex or need repainting, and it costs less than Rockdoor.
5-point locking and a 3-star anti-snap cylinder
Over 80 styles in three collections
30 colours outside, white inside
Front, back and side doors, with or without sidelights
A solid core, not a hollow panel, held shut by multi-point locking. A thick, heavy door that is hard to flex or lever open.
No rot, no repainting
Unlike timber, a composite skin won’t rot, warp or need sanding and varnishing. A wipe with soapy water keeps it clean.
Warmer
An insulating foam core, double glazing and weatherproof seals cut draughts and heat loss at your door.
Real choice
Traditional or modern styles, a wide range of colours, glass designs and handles, all with a timber-grain finish.
Options
Composite door colours, glass and finishing touches
Everything is chosen at the design stage, so the price in your quote is the final price.
Every photo is a door we fitted, apart from Pebble Grey, Rockdoor’s newest colour, shown close up. Screens show colour a little differently from daylight. See every colour in our Rockdoor colours guide.
Colour£70for a Rockdoor colour other than white
Rockdoor comes in 14 colours, with a different colour inside and out if you like: 196 combinations. GRP comes in 30 colours outside, with a white inside.
Glass and privacy£80–£260for a glass design on a Rockdoor
Obscured, frosted and decorative glass keeps your hallway private from the street and still lets the light in. Rockdoor’s exclusive 3D glass designs have a genuine three-dimensional texture. Or choose a solid panel.
Sidelights and toplights£300–£500per panel
Single or double sidelights, a toplight, or both, on either range. Worth it for a dark hall, or an opening wider than one door.
Handles and hardware£100–£180for a bar handle on a Rockdoor
A bar handle gives a contemporary look and a lever handle suits a traditional door, in chrome, black, gold and other finishes.
Costs shown are what each option adds to the starting price.

Fitting day
That’s how far ahead our diary is booked. Old door out, new door in, lock and handle tested, everything cleaned up, and a walk-through so you know how it all works.
I could not be happier with my new front door, I absolutely love it. Jim and Josh were fantastic to deal with throughout the process.…Responsive to messages when I had queries, everything was easy. On the day of the install both Josh and Jim were organised and tidy. They had great attention to detail and I now have a beautifully fitted, beautiful new door that keeps drafts out and reduces traffic noise and feels very secure.
Had big problems with my 15 year old front composit door . It had dropped, Hinge screws wouldn’t tighten , couldn’t get it lock properly.…srugling to open and shut . not used it for 6 weeks . Been looking at getting a replacement, when i came across jim . What a knight in shining Armour… One phone call , arranged a date to come over . well that day was today ! went above and beyond, proper nice gents . come with all the parts to fix it ..& refurbished were it needed . words can’t express how happy i am . i’m going to replace my old back door soon to a newer design & jim definitely will doing it .. once again jim a very big thank you ( mick ) .
A composite door bonds several materials together: a tough outer skin, an insulating foam core and a reinforced frame, with multi-point locking. That makes it stronger than uPVC and easier to look after than timber. See our Rockdoor and GRP ranges.
How much do composite doors cost fitted?
GRP composite doors start from £1,500 fully fitted, including VAT, and Rockdoor from £1,900, with stable doors from £2,350 and French doors from £3,400. The price we quote is the price you pay. See our composite door prices guide.
Are composite doors better than uPVC?
For most homes, yes. A composite door has a solid core rather than a hollow panel, so it is stronger and insulates better.
How long do composite doors last?
A good composite door, fitted properly, gives you many years of use with very little upkeep, because the skin doesn’t rot, warp or need painting. Rockdoor and GRP doors both come with a 10-year manufacturer’s guarantee.
Are composite doors secure?
Yes. Every door we fit has multi-point locking and an anti-snap cylinder as standard. Rockdoor goes further, with S-Glaze sealed glass and an aluminium-reinforced frame, and it is tested to PAS 24.
Should I choose Rockdoor or GRP?
Rockdoor is the most secure door we fit, with a thicker door, aluminium reinforcement and S-Glaze glass, from £1,900. GRP costs less, from £1,500, and is still a big step up from uPVC. For other premium brands, see Rockdoor vs Solidor vs Endurance.
What colours do composite doors come in?
Rockdoor comes in 14 colours, and you can choose a different one inside and out. GRP comes in 30 colours outside, with a white inside. See Rockdoor colours on real doors.
Do composite doors swell or stick in hot weather?
All doors move a little with temperature, and a dark colour on a south-facing door warms up the most. A lighter colour helps, and so does lifting the handle fully each time you close the door. Rockdoor’s aluminium frame limits the movement.
How long does it take to get a composite door fitted?
Allow around seven weeks from order to fitting. Your design and price come within 24 hours of your photos; then we survey, and the door is made to measure.
Can I buy a composite door without fitting?
Yes. If you’re outside our area or have your own fitter, we can supply Rockdoor and GRP doors for delivery across mainland UK. Get in touch for a supply-only quote, or browse spares in our online shop.
