How long do composite doors last?

A professionally-installed composite door will comfortably last 30 years or more with almost no maintenance beyond a wipe-down.

Do composite doors fade?

Modern GRP skins carry UV inhibitors and a 10-year colour-fastness guarantee. Bright colours in south-facing positions may soften slightly over a decade; dark colours are unaffected.

Can composite doors warp?

No — the timber or engineered-timber core and rigid GRP skins keep a composite door dimensionally stable across UK temperature and humidity ranges.

Are composite doors energy efficient?

Yes. A typical composite door has a U-value of around 1.0 W/m²K, compared to 1.4 for uPVC and 3.0 for a traditional single-panel timber door.

Do composite doors increase house value?

Kerb appeal is one of the biggest single factors in estate agent valuations. Estate agents routinely add £3,000 to £5,000 to asking prices after a new composite front door.

Can I change the glass on a composite door?

Yes — the glass unit is bonded into the slab but can be replaced by an installer if it breaks. Choose your glass carefully at spec stage as an aesthetic change later is more expensive.

How long does composite door installation take?

A single-door replacement is typically a same-day job — 3 to 5 hours from arrival to a fully cleaned-up finish.

What guarantees are available on composite doors?

Every door we install carries a written 10-year guarantee covering the door slab, hardware and workmanship.
