Surplus Doors & Windows

Reclaimed period doors, surplus internal sets and end-of-line uPVC and timber windows. Restoration character or new-build savings — sourced from joiners, glaziers and demolition across the UK.

Doors and windows are the surplus category with the widest price spread: an end-of-line uPVC casement flat-pack sells at £120 against a £340 merchant retail, while a genuine Victorian six-panel front door with original stained glass reaches £600–£1,200 at heritage yards. Both are surplus, both are on SurplusBuilder, and both are on the same page below.

For new-build and renovation buyers, surplus internal-door sets are the fastest saving on a fit-out budget — full houses' worth of Howdens, Todd Doors or Deanta stock appear as HMO refurbishment clearance or joinery over-orders every month. Reclaimed sash windows, panelled front doors and stained-glass lights command a premium because they can't be replicated — but they're often cheaper than a bespoke joiner's new commission.

Every listing below shows dimensions, glazing spec (single/double/triple, U-value where known), material, condition grade and fire rating for internal fire doors.

Buyer's checklist

  • ✓Measure the opening, not just the door — allow for 3mm clearance on the head and each stile.
  • ✓Reclaimed sash windows almost always need slim-profile secondary glazing or refurb with 12mm slim units to meet current U-values.
  • ✓Fire doors (FD30/FD60) lose certification when re-hung — for regulated buildings, buy new fire doors, not reclaimed.
  • ✓Check glazing: single glass is fine for garages/sheds only. Modern lets require double or triple.
  • ✓Ironmongery (hinges, locks, letterplates) is often as valuable as the door itself — check it's included.
  • ✓For period sash windows, confirm the box is intact — replacing a rotten pulley-stile box is 60% of the restoration cost.

Frequently asked questions

Will reclaimed sash windows meet Building Regs?+

Reclaimed sashes often need secondary glazing, slim-profile 12mm double units, or full refurbishment to meet current U-values (target 1.4–1.6 W/m²K for a heritage-friendly upgrade). Listings note the glazing type — plan for £400–£900 per sash to bring a reclaimed unit up to current thermal spec.

Are surplus internal doors as good as new?+

Yes — most are new surplus from Howdens, Deanta, JB Kind or Todd Doors, over-ordered on housebuilder sites. Same materials, same finish, same warranty when unregistered. Check for scuffs on the leaf face before buying.

Can I use a reclaimed door as a fire door?+

No. FD30 and FD60 certification requires a documented, tested door leaf-and-frame combination. Reusing a reclaimed door as a fire door is a Building Regs failure and invalidates house insurance in the event of a fire.

How do I know if a reclaimed door is repairable?+

Check the stiles and rails for rot at the joints (probe with a screwdriver). Look for splits running through mortices — usually terminal. Cracked panels are usually fine. Warped over 8mm along the length is often uneconomic to fix.

What glazing spec do modern rentals need?+

Double-glazed as a minimum, ideally with argon fill and a low-E coating for U-values below 1.6 W/m²K. Single-glazed rented properties are increasingly non-compliant under EPC C requirements post-2028.

Do surplus uPVC windows come with a warranty?+

New surplus stock retains the manufacturer's warranty (typically 10 years) when it hasn't been registered by the original buyer. Confirm the manufacturer sticker is intact and note the batch/date code.
