A cleaning quote is almost never a single flat number pulled from the air. It’s built from a handful of measurable inputs: the size of the space, how often the work happens, the condition of the property, and the specific tasks you want done. Two homes on the same street in Melbourne can get quotes that differ by a hundred dollars or more, and usually there’s a concrete reason for the gap. Understanding those reasons is the difference between feeling overcharged and knowing you paid a fair rate.

Square Footage Math

Most residential and commercial cleaning quotes start with area. A cleaner estimates how long a space takes to clean, and floor size is the fastest proxy for that time. Larger homes have more surfaces, more floors to mop, and more corners to reach, so the base figure climbs roughly in step with square metres.

But raw size isn’t the whole story. A 90-square-metre apartment packed with furniture, shelving, and clutter can take longer than a 130-square-metre home that’s mostly open plan. The number of bathrooms matters more than almost anything else, because bathrooms are slow, detailed work. Kitchens are the same. When a company sends someone to walk through the property before quoting, they’re adjusting the square-footage math for these realities rather than charging you by the metre alone.

Frequency And Discounts

How often you book changes the price per visit, sometimes dramatically. A weekly or fortnightly service costs less per clean than a one-off, because a maintained home never gets very dirty. The cleaner isn’t fighting weeks of built-up grime each time, so the job is faster and more predictable. That efficiency gets passed back as a lower recurring rate.

One-off and first-time cleans work the opposite way. The initial visit to a home that hasn’t had professional attention often carries a higher rate, because it involves deep work the ongoing schedule won’t need again. The most expensive category tends to be specialised jobs with a hard deadline and an inspection at the end, such as an end-of-lease clean. If you’re preparing to hand back keys, a detailed moving out clean-up guide shows why that service is priced above a standard visit: it covers ovens, skirting boards, window tracks, and other areas a routine clean skips. Companies like Legion OTG structure these tiers openly, so the discount for committing to a regular schedule is easy to see against the premium for a single intensive job.

When you’re comparing quotes across a few Melbourne providers, ask each one to price the same frequency. A weekly rate from one company and a one-off rate from another aren’t the same product, and lining them up side by side is the only fair comparison.

Hidden Fee Traps

The final number on your invoice sometimes includes charges the original quote glossed over. The most common is the assumption gap: a quote covers general cleaning, but the fine print excludes interior windows, inside the fridge, wall spot-cleaning, or carpet steaming. Each of those may be a separate line item added later.

Watch for a few specific patterns. Some companies quote per hour rather than per job, which shifts all the risk onto you if the work runs long. Others apply surcharges for parking, travel to outer suburbs, or supplying their own products and equipment. Weekend and public-holiday bookings frequently cost more. None of these are dishonest on their own, but they should appear in the quote, not surface on the bill.

The simplest protection is to ask what is not included. A reputable cleaner will tell you plainly and put the scope in writing. If a quote seems far lower than every other one you’ve received, the difference is almost always in what’s been left out.

Before you accept any quote, send the provider a written list of exactly what you want done and ask them to confirm each item is covered at the stated price. That one message turns a rough estimate into a firm agreement and removes nearly every surprise from the final bill.
