7 Things to Check Before Hiring a Window Cleaning Service

Brisbane has no shortage of window cleaners, but the quality and professionalism varies considerably. Choosing based on the lowest price alone often leads to a mediocre result, hidden extras, or worse, damage to your glass or property. Here are seven things worth checking before you commit.

1. Experience and Track Record

Ask how long the company has been operating and what types of properties they service. A cleaner who primarily does residential work may not have the equipment or technique for multi-storey commercial buildings. One who mainly does commercial may rush through a detailed heritage home.

Look for evidence of ongoing work in your suburb. Companies that clean regularly in your area will know local water quality issues, the types of homes and glass in the area, and the environmental factors that affect how quickly windows soil.

2. Reviews and Reputation

Google reviews are the most reliable source of genuine feedback. Look at the volume of reviews, not just the rating. A company with 200 verified reviews at 4.9 stars is a much safer bet than one with 12 reviews at 5 stars. Read through the detail of negative reviews as well as positive ones — how the company responds to complaints reveals a lot about how they operate.

Facebook recommendations in local community groups are also worth checking. Brisbane suburb groups on Facebook are active and honest; locals call out poor tradespeople as readily as they recommend good ones.

3. Insurance Coverage

This is non-negotiable. Any professional window cleaner working on your property should carry public liability insurance. If something goes wrong — a window breaks, a ladder damages your render, someone slips — uninsured contractors leave you exposed.

Ask for the insurer's name and policy number. A reputable company will share this without hesitation. It's worth noting that a significant proportion of small service businesses operate without adequate cover, so asking directly is important.

4. Safety Equipment and Protocols

Working at height carries real risk. The company you hire should have and use the appropriate equipment for your property type: ladders with standoffs for gutters, water-fed poles for reaching upper windows without ladders, and proper harness systems for anything above two storeys. They should also know the restrictions around working near power lines.

Ask what their procedure is for your specific property. A window cleaner who gives you a vague answer about how they'll handle your upper-floor windows is one to be cautious about.

5. What's Actually Included

Window cleaning quotes often don't include the same scope. Before you compare prices, clarify whether the quote covers:

Interior windows as well as exterior. Frame and sill wipe-down. Flyscreen removal and cleaning. Window track cleaning.

The base price for most services covers exterior glass only. Everything else is typically an add-on. For a full breakdown of what a professional service includes, see our guide on what window cleaning includes.

6. Pricing Transparency

A reliable company will give you a clear written quote before starting work. Be cautious of very low price estimates that seem too good to be true — they usually are, and the final invoice often looks quite different. Ask specifically whether the quote is fixed or subject to change based on what they find on the day.

7. Guarantee and Aftercare

A confident company stands behind their work. Ask whether they offer a satisfaction guarantee and what the process is if you're not happy with the result. This is a simple but telling question. Companies that take quality seriously are happy to answer it clearly.

Questions to Ask Before Booking

Before confirming a booking, it's worth asking:

How will you access the upper windows on my property? What cleaning solution do you use, and is it safe for my window frames and garden? Do you carry public liability insurance, and can I have the policy details? Is there anything about my windows that might affect the price on the day?

A professional company answers these questions directly and without hesitation. If the answers feel evasive or overly vague, trust that instinct.
