How long does a loft conversion take to do?


This is dependent on the size, shape, design of the conversion and what work is involved; a small “velux loft conversion” will be quicker than a “build up gable end with full width rear dormer loft conversion”.

Here is a typical sequence of work but is not set in stone as many factors can alter the sequence, the weather being a big one:

  • Scaffolding erected prior to work commencing.
  • Opening made for roof access, steel girders installed, bulk delivery of materials.
  • New independent floor structure installed.
  • Cables run for smoke alarms in the floor structure for rooms below, “feed” for electrics and plumbing established.
  • Roof stripped and extended if required.
  • Dormer constructed if required.
  • Roof windows fitted.
  • Weather dependant we will work on the exterior as much as possible to get the construction weatherproof.
  • Internal stud and1st fix timber work.
  • 1st Fix Electrics and Plumbing.
  • Loft insulated and plaster boarded.
  • PVC windows/doors fitted.
  • Ceiling in stairwell position cut out as neatly as possible and new bespoke staircase installed.
  • Plastering.
  • Tiling if required.
  • 2nd fix Carpentry, Electrics and Plumbing.
  • Juliet balcony fitted if required and any other external work finished if required.
  • Painting if required.

Typically a loft conversion can take between 4 and 8 weeks depending on the type and size.

Severely adverse weather can sometimes delay the project but every effort will be made to work around the weather and depending on certain lofts a scaffolding canopy may be included/added into the job price. This then won’t let the weather hold up any work.
