Question 1

How much do composite French doors cost in Cornwall?

Accepted Answer

Composite French doorsets in Cornwall are typically £2,195–£3,495 fitted, depending on width, glazing spec and side panels. Every quote is fixed and includes removal, disposal, fitting and a 10-year guarantee.

Question 2

Are composite French doors better than uPVC French doors?

Accepted Answer

For Cornish weather, yes. The composite slab is dimensionally more stable than uPVC through humidity swings, holds colour longer against salt air, and delivers PAS24 security as standard rather than as an upgrade.

Question 3

Can I have French doors on a coastal property?

Accepted Answer

Yes — every French doorset we install on the coast comes with marine-grade stainless furniture, upgraded seals and a wind-driven-rain-tested threshold. We install French doors on cliff-top and harbour-front properties across Cornwall.

Question 4

What's the widest French door opening you can fit?

Accepted Answer

Standard composite French doorsets go up to 1800mm total width. Beyond that we specify a French door with side panels or step up to a bi-fold — we advise at the free survey.

Question 5

Are French doors secure enough for a rear elevation?

Accepted Answer

Yes. Our French doorsets are PAS24-tested with hookbolt shootbolts top and bottom on the slave leaf and a 5-point multi-point lock on the master, plus a 3-star anti-snap cylinder.

Question 6

How long does French door installation take?

Accepted Answer

A straightforward French door replacement is a single-day install — 5–7 hours from removal to finished, sealed and tested.
