FAQ

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

Why do we check the wall waterproofing now?

The builder can roll the membrane up into the wall easily now. Once plaster is up, you cannot see where the seal starts.

Are you checking the wiring?

No. We document visible clearances. The installation itself must be done by a licensed electrician.

How long will a Greenbank lock-up visit take?

Allow one to two hours. A steep roof or double storey adds time.

What about the frame items seen earlier?

We check them again and note if they are fixed or remain open.

Why check the ridge capping?

Cracks are easier to fix before the tiles are on. A crack later can let water into the timber frame.

Does the builder fix service spacing quickly?

Usually yes. It is often just a clip or a small spacer the carpenter can add.
