Ask five Glasgow installers what a composite door costs and you will get five different answers, usually somewhere between £950 and £2,500 fitted. That gap is not random. It comes down to the door itself, the frame, the glass, and the state of the opening it is going into. Here is an honest breakdown so you know what you are paying for before anyone measures up.
For a standard single composite front door, supplied and fitted, most Glasgow homeowners pay somewhere in the region of £950 to £1,600. That usually covers the door slab, a new uPVC or composite frame, a multi-point lock, standard glazing, handles and letterplate, plus removal and disposal of the old door.
Prices climb from there. A door with a side panel or top light typically lands between £1,400 and £2,200, while premium ranges with solid timber cores, flush finishes or bespoke colours can push past £2,500. If you already have the door and only need fitting, labour alone is usually £200 to £400 for a straightforward swap, though most suppliers in the city prefer to quote supply and fit together so the guarantee covers everything.
The core of the door matters most. Cheaper composite doors use a foam core, which is fine for insulation but lighter and less rigid. Solid timber core doors cost £300 to £600 more but feel noticeably more substantial and tend to resist warping better, which is worth considering given how much driving rain the west of Scotland gets.
After that, it is the details. Glazing choice makes a real difference, as decorative or obscured glass units add £100 to £300 over plain glass. Colour matters too: white and standard shades like anthracite are usually included, while bespoke RAL colours or a different colour inside and out add £150 to £400. Hardware upgrades such as a 3-star cylinder lock, which is worth having, add £50 to £100 if not already included.
Older housing stock across the city, particularly pre-war semis in areas like Shawlands, Dennistoun and Knightswood, often has openings that are not square or have crumbling brickwork around the frame. If the installer needs to rebuild or make good the reveal, expect an extra £100 to £250 on the quote. Tenement main door flats and closes can also complicate access and disposal, which some firms price in.
If your home is in a conservation area, such as parts of the West End, Pollokshields or Dowanhill, you may need to match the style of the original door, and planning rules can restrict what you fit on a listed building. A reputable local installer will flag this before you order rather than after. It is also worth checking that whoever fits the door will register the installation for building standards compliance and provide an insurance-backed guarantee, not just a manufacturer warranty on the slab.
Two quotes £400 apart are often not for the same thing. Before comparing numbers, check whether each quote includes the frame, the threshold, the lock specification, internal making good, and disposal of the old door. A cheap headline price that excludes the frame or uses a basic euro cylinder is not actually cheap.
Get the guarantee terms in writing. A typical composite door should carry around 10 years on the slab and frame, with the installation itself guaranteed separately. Ask how long the installer has traded locally and whether they use their own fitters or subcontract, because that is who turns up if something needs adjusting a year later. A decent installation takes half a day to a day, so be wary of anyone promising to squeeze it into an hour.
