Common questions

Frequently asked

Should I get sliding doors or bi-folds? +

Sliding doors give larger uninterrupted glass when closed; bi-folds give a wider full-open aperture. For garden views and most of the year, sliders win on aesthetic and thermal performance. We'll talk through the specific layout during your survey.

How secure is a composite door? +

Every door we install is PAS24:2016 accredited and Secured by Design. Combined with a Yale 3-star or Ultion cylinder it represents the highest level of front-door security available on the residential market.

Will it warp or fade in the sun? +

Composite doors are stable across temperature extremes — no warping, no swelling, no shrinking. The colour finishes are GRP-bonded and rated for 25+ years of UK weather.

Can I get a matching back door? +

Yes — we typically supply matching front and back doors as a package, often with a small discount for combined installation.

What's the lead time? +

Most doors are surveyed within a week and manufactured in 2–4 weeks. Installation itself takes a single morning.
