Could anyone provide a ballpark estimate as to how many days it would take 2 qualified (LBP) builders to install 5x new windows and 1 set of french doors as direct replacements for the existing windows/doors up to current building code standards and ensuring weathertightness?

i.e.

• Remove existing windows/doors
• Ensure holes are properly dressed and prepped
• Install the new windows
• Apply finishing inside and out (architraves, facings, etc)

Assume:

• Direct-fixed timber weatherboard cladding
• Existing windows are aluminium
• Lintels, base plates and framing are all fine and meet the building code
• They don't do any painting or anything

Am I way off in assuming it would take a team of 2 capable guys around 2-4 days to do this work?
