Carpenter: New bi fold door hanging

Pricing guide

Cost is driven mainly by the door type and installation complexity: standard internal hollow doors are usually simpler than heavy external or fire‑rated doors that need extra handling, fixings and weatherproofing. Quotes generally comprise a single callout plus hourly labour and consumables, and whether you supply the door or hardware will affect the materials component. After‑hours attendance, difficult access or the need to repair or reinforce the frame can also increase the overall scope.

• Door type and weight

  Standard hollow‑core internal doors are typically quicker to fit than heavy solid‑core, metal or external doors that need two‑person handling.

• Frame condition and preparation

  If the existing frame is damaged, warped or requires resizing, additional repair or preparatory work will usually add labour time.

• Hardware complexity and certification

  Multi‑point locks, specialised fittings or fire‑rated hardware often need more time and precision and may require certified components.

• Who supplies the door and materials

  Many homeowners supply the primary door while installers supply consumables and basic hardware, but asking for the installer to provide the door will change the materials list.

• Access, handling and timing

  Tight access, heavy doors or after‑hours attendance typically increase labour requirements and can affect the final quote.
