FAQ

Lock-up (pre-plaster) inspections in Castle Hill: common questions

Why are box gutters such a focus?

A box gutter sits inside the roof line, so when it overflows the water goes into the house. Joints, upturns and sumps all have to be right.

Who cuts bracing?

Usually a trade running pipes or cables after the frame stage. It needs repair and sign off before plaster.

Is this the last chance to see the wall cavity?

Yes. Once linings are on, insulation, pipes and bracing are hidden.

Is the roof itself inspected at lock-up?

Yes, from the roof where safe access exists, otherwise from scaffold or with the drone.

Is lock-up worth booking on a simple single storey home?

It is optional on a simple design. On homes with box gutters, parapets or flat roof sections it earns its place.

When does the lock-up report reach me?

Usually the next morning, so it reaches the builder before plastering starts.
