Contact sellerHow buying works

Condition grade 6/10 (B-grade). Assessed by the seller at listing; figures below relate to this specific lot of 4-pane bi-fold.

About this lot

Surplus to a luxury extension. Slim sightlines, thermally broken. Sealed and stored in workshop. Located in Liverpool — collection or arranged regional delivery available. Direct from Liverpool Urban Reclamation, a demolition operating out of Liverpool; live for 8 days.

This is exactly the kind of material that typically ends up in a skip costing the seller money; buying it diverts it back into a build. It is graded down on appearance alone; structurally and functionally it performs as A-grade.

Questions about this lot

Are the stated sizes the door leaf or the frame?+

Leaf sizes unless the listing says 'with frame'. Always measure your structural opening and allow for packers and tolerance before buying.

Can old doors be trimmed to fit?+

Solid timber doors trim comfortably by up to 6mm per edge. Engineered and fire doors have strict trim limits — check the certification label first.

Is the glazing safety glass?+

Modern units from Liverpool Urban Reclamation are toughened where regulations require. Original period glass is not safety glass — re-glaze below 800mm or in door zones.
