Fine plaster dust, which takes several passes to remove.
Paint, glue and sealant marks on surfaces and glass.
Whether windows and frames are included.
Access for equipment such as industrial vacuums.

How long it takes

How to pay less

Ask the builder to clear rubble and large debris first.
Clean after the work is fully finished, not between stages.
Send photos so the cleaner can quote the right amount of time.

Before you hire

Ask whether they have cleaned after building work before, and for the equipment they use for dust.
Ask whether they remove rubble, or only clean, so you can book a waste collection if needed.
Book the clean after the builders have fully finished, not while work continues.
Ask whether a second visit is possible if dust settles after the first.

💬 Questions about after builders cleaning costs

When should the clean happen?

Once the builders have finished and taken their tools. Ideally before you move furniture back in, so cleaners can reach everything.

Why does it cost more than a normal clean?

Building dust is fine, sticky and gets everywhere, so it takes more time and more passes. That's why cleaners in London usually price it by the job.

Can a cleaner remove paint and sealant?

Light splashes, yes. Anything set hard on delicate surfaces may need the builder to put right. Tell the cleaner what you can see when you request quotes.

Why not clean it myself?

You can, but fine plaster dust lifts into the air and settles again. Professionals use equipment that removes it, so you do not end up cleaning twice.
