FAQs – Composite Doors Explained
What makes composite doors different from UPVC or timber?
Composite doors are made from multiple materials for superior strength, insulation, and weather resistance. They won’t warp or fade, and they offer a solid, secure feel with minimal maintenance.
Can I customise my door design?
Yes—you can use our Rockdoor or Endurance door designers to create a fully bespoke door. Choose your colour, glazing, hardware and finish, then we’ll take care of the rest.
How long does installation take?
Most installations are completed in just one day. We confirm all timescales in advance and keep things tidy and efficient.
Where do you install doors?
We install across Lincolnshire, covering towns, villages and rural areas throughout the region.
We replaced our flimsy old back door with a Rockdoor and the change is unbelievable. It’s completely solid, no more draughts, and it locks tight with minimal effort.
Composite Doors Scunthorpe were easy to deal with, gave us loads of colour and hardware options, and Jay made sure everything was fitted perfectly. Definitely a worthwhile upgrade.
