Most people wait until their windows look like a Jackson Pollock painting before they start shopping for a cleaner. That's the worst time to make a smart decision. A little upfront work saves you from getting ripped off or ghosted.
Red Flags in Quotes
If the quote comes back suspiciously low, they're either planning to cut corners or they'll hit you with add-ons later. A price that's half the next guy's bid means they're using cheap tools, skipping safety gear, or planning to rush. On the flip side, a quote that's way higher than everyone else with no explanation is just a sucker price. Ask for a breakdown: labor, materials, travel. If they can't or won't give one, walk.
Red Flags in Communication
Slow replies, vague answers, or dodging your questions about insurance and methods are all bad signs. If they can't tell you what kind of water they use or how they handle high windows, they're either inexperienced or hiding something. A professional answers clearly and directly. Someone who says 'don't worry about it' is asking you to trust them with zero proof. Don't.
Red Flags in Contracts
A contract that's a single page of fine print with no cancellation clause is a trap. Watch for language that says you're on the hook for damages they cause, or that they can subcontract the job without telling you. If the contract doesn't list exactly what's included — number of windows, screens, tracks, interior vs. exterior — you're signing a blank check. Never sign anything that says 'standard service' without defining it.
How to Protect Yourself
Get three quotes, but don't just pick the middle one. Ask each person for proof of insurance and a written scope of work. Pay by credit card, not cash or check — gives you chargeback rights if they bail. Take photos of your windows before they start, especially any damage. And never pay the full amount upfront. A deposit is fine, but the rest should be due after you've inspected the work.
