Frequently asked questions
How should I choose a window cleaning service in Portland?
Look at verified online reviews and the number of reviews to gauge consistency, confirm the company’s insurance and licenses, and ask about the specific services included (glass only, frames, screens, tracks). Get written estimates from multiple providers and compare timelines and availability to match your needs.
What does professional window cleaning typically cost?
Cost varies based on factors like the number of windows, how accessible they are, property size, and whether additional services (gutters, screens, frames) are included. Expect estimates to reflect those variables; ask for a detailed written quote so you can compare apples to apples.
What should I check before hiring a window cleaner?
Confirm the company carries liability insurance and asks about safety procedures for ladders or multi‑story work, and request references or recent customer feedback. Also verify what’s included in the job, any guarantees or follow-up policies, and whether you’ll need to prepare the area before the crew arrives.
