Naples has no shortage of window cleaning options. A quick search turns up dozens of companies ranging from large regional operations to solo operators running out of unmarked vans. Most homeowners choose based on price — which is exactly how they end up with scratched glass, no-shows, and cleaning bills that cost more to fix than the original job would have.

Here’s how to actually evaluate a window cleaning company before you hand over access to your home.

1. Licensing and Insurance — Non-Negotiable

Any company working on your home should carry at minimum:

• General liability insurance — covers glass damage, property damage, and accidents
• Workers’ compensation — covers injuries to technicians on your property

Ask for a certificate of insurance before booking — not just a verbal confirmation. Uninsured operators are common in this market, and if a technician breaks a window or injures themselves on your property, you could be liable. A legitimate company will email you a COI without hesitation.

2. How They Quote

A professional company quotes by window count, scope, and access difficulty — not with a vague “starting at $X” over the phone. Before your first visit, they should ask about:

3. Equipment and Methods

The tools a company uses tell you a lot about the quality of their work. Ask what solution they use on glass — specifically whether it’s safe for coated or low-E glass, which is common in newer Naples homes. Some cheap cleaning solutions etch coatings over time.

For hard water mineral removal — which is almost always needed in Naples — ask whether they use a commercial-grade mineral remover or just extra scrubbing. Scrubbing alone can scratch glass. Professional mineral removal uses acid-based solutions applied carefully with appropriate dwell time.

4. Reviews That Are Actually Useful

Don’t just look at star ratings — read what the reviews say specifically. Useful signals:

• Reviews that mention the technician’s name (sign of a consistent crew)
• Reviews from gated community residents (sign they know how access works)
• How the company responds to negative reviews (tells you more than the review itself)
• Volume of reviews over time — steady flow beats a burst of 20 reviews in one week

5. Recurring vs. One-Time Service

In Naples’ climate, one-time cleaning is rarely enough. Ask whether the company offers a scheduled maintenance program and what the discount looks like. A company that only does one-offs isn’t set up to be your long-term vendor — and building that ongoing relationship is where most of the value in professional window cleaning comes from.
