What happens during a first deep clean (and why most companies require one)

Almost every recurring cleaning service starts with a deep clean. Here's what's actually in it, why it exists, and how it sets up every visit after.

Short answer: a first deep clean is a top-to-bottom reset of the whole house. It clears the buildup a regular visit isn't built for, so every visit after can focus on keeping things clean instead of catching up.

Why companies require a deep clean first

A regular cleaning is designed to maintain a home that's already in good shape. If the first visit tried to do that in a home with months of buildup, one of two things would happen: the visit would run long, or parts of the house would get skipped. Neither feels good.

A first deep clean solves that. It brings the whole house to a baseline, so the team can learn your home and every visit after starts from clean. That's why most companies ask for one, and why some call it a "refresh" or "initial clean."

What a deep clean usually covers

Exact lists vary by company, but a first deep clean generally goes further than a regular visit in these areas:

Inside the fridge, inside the oven and inside cabinets are often treated as extras, so ask what's included before you book.

Common questions

Do I need a deep clean if my house is already pretty clean?

Most companies still ask for one because it sets a consistent baseline and lets the team learn your home. With Back to Clean it's a flat $99 either way.

How long does a deep clean take?

Longer than a regular visit, and it depends on the size and condition of the home. That's why many companies charge by the hour for it. Ours is a flat $99, so the time doesn't change your price.

Is inside the fridge and oven part of a deep clean?

It varies by company. At Back to Clean, inside the fridge, oven and cabinets is our Extra Detail add-on for $20 a visit.

Do I need to be home for the deep clean?

No. Many people share a door code or lockbox, and entry details stay private to your team.
