How to Choose a Window Cleaning Company in Phoenix: A 10-Point Checklist
Phoenix has more window cleaners than most cities because the barrier to entry is low — a truck, a squeegee, and a Facebook ad. That's fine for a $50 pane, but for a full-home clean at $200–$400, you're trusting someone with ladders on your walls, chemicals on your paint, and access to your home. Here's how to pick right.
The 10-point checklist
- Registered LLC in Arizona with a current AZ business filing.
- Active General Liability insurance ($1M+) — ask for the certificate.
- Workers' Compensation coverage — protects you if a crew member is injured on your property.
- Dishonesty bond — required for anyone working inside your home.
- BBB profile with an A+ rating and long-term history.
- Documented deionized-water process for exterior work in hard-water zones.
- Written streak-free guarantee — not just verbal.
- Matching uniforms and marked vehicles — indicates a real team, not a subcontractor.
- Background-checked crews if you have staff, kids, or pets at home.
- Transparent pricing — a written quote before the crew arrives, not a 'we'll see when we get there' price.
Red flags
- Door-to-door sales pitch with same-day 'discount' pressure.
- Cash-only pricing with no invoice offered.
- Vague answers about insurance or bonding.
- No physical business address, only a cell phone.
- Reviews clustered in a two-week window with generic wording.
What good pricing looks like
A trustworthy Phoenix window cleaner will give you a quote in writing, break out any add-ons (screens, hard-water, solar panels), and not require a deposit for standard residential work. If the number sounds too good — under $100 for a full home — the crew is either uninsured, using tap water on your glass, or planning to upsell on arrival.
Questions to ask first
- 'Are you insured, bonded, and a registered Arizona LLC?'
- 'Do you use deionized water on exterior glass?'
- 'What's your streak-free guarantee?'
- 'What's the total price, in writing, including screens and tracks?'

Frequently asked questions
How do I verify insurance for a Phoenix window cleaner?
Ask for a certificate of insurance (COI) emailed directly from their carrier — not a screenshot. Any legitimate company can provide one in an hour.
Is BBB accreditation worth checking?
Yes — it's not the only signal, but a long-standing BBB-accredited profile with A+ rating is a strong indicator you're dealing with a real, established business.
Should I get three quotes?
Two is usually enough. What matters more than the third quote is comparing what's actually included — insurance, deionized water, screens, guarantee.
