Fit a composite door correctly and the result is straightforward: a door that locks smoothly every time, keeps the weather firmly on the outside, and still looks like new well beyond the point a painted timber door would need stripping back and redecorating. Skipping any of those steps is the usual reason a door that looked fine on day one starts sticking or letting in draughts within a year or two.
It is worth booking a survey before the worst of the weather arrives rather than during it. That end-to-end approach is what keeps a composite door doing its job for the long term.
No pressure, no obligation
- Clean working practice: Old doors and frames are removed and waste cleared away, leaving the site tidy.
- Insurance-backed guarantee: Installations come with an insurance-backed guarantee, giving you protection beyond our own workmanship.
- Clear communication: We agree access, timings and any special requirements before fitting day, not on the day itself.
How we fit a composite door, start to finish
Once fitted, a composite door should open and close smoothly with a single lift of the handle, lock securely with the multi-point mechanism engaging cleanly, and sit flush and square in its frame with no visible gaps. Once the order is confirmed, the new frame and door leaf are made to the exact opening size rather than a standard stock size.
On fitting day the old door and frame are removed, the opening is checked, cleaned and made good, and the new frame is fixed in level, plumb and square before being fully sealed. The door leaf is then hung, the multi-point lock and hardware fitted and adjusted, and the whole installation checked for smooth operation before we finish and clear away.

Composite doors across multiple units or properties
Rental properties need doors that stand up to changeover after changeover without constant repair calls. A composite door specified with a robust lock and hinge set handles that use, and the range of colours and glazing lets it still fit the look of the premises.
A typical single composite door replacement
- Initial enquiry: We confirm the lintel and surrounding brickwork are sound before removing the old frame.
- Survey and specification: On fitting day the existing door and frame are taken out and the opening checked, cleaned and made good.
- Weatherseal check: Seals around the full frame perimeter are checked for continuity, with no gaps left unsealed.
- Final check and clear away: We check the door opens, closes and locks correctly, seal and finish the reveals, and clear away all waste before leaving.
Composite Doors in Thornbury: common questions

Is the installation guaranteed?
Yes — every composite door installation comes with an insurance-backed guarantee, and we're fully insured throughout the job.
How long does a composite door last?
A well-fitted composite door is built to perform for many years with minimal maintenance, since the GRP skin doesn't rot, fade significantly or need repainting the way timber does, and the solid core keeps its shape rather than warping.
Is the quote really free and no-obligation?
Yes, there's no charge for the survey or the quote. We'll take accurate measurements of the door opening, talk through what you're after, and give you an itemised price before you commit to anything.
Will a composite door stop condensation around the door?
A properly fitted composite door with energy-rated glazing significantly reduces cold spots and draughts that contribute to condensation around the frame, compared with an older, poorly sealed door.
What maintenance does a composite door need?
Very little — a periodic wipe down with warm soapy water keeps the finish looking good, and the multi-point lock and hinges benefit from an occasional check that they're moving smoothly, but there's no repainting or sealing required.
