The cleaner your windows, the lighter and brighter your home. No wonder real estate agents and interior designers recommend squeegeeing your panes once or twice a year. You can handle this task yourself, but if you don’t have the time—or you fear ladders—hiring a pro will get rid of the grime in no time. Here’s how to find clear winners.
On average, our surveys of consumers found that they rate window washing services higher than housecleaning companies. But this probably has less to do with the quality of the companies than with the relative difficulty of the jobs: It’s easier to do a shining job washing windows than to clean an entire home.
Our research shows it pays to shop around: The highest-priced window cleaners charged prices that were, on average, more than double those of the lowest-priced company. Plus, it’s simple to get price quotes. Make a list of your windows, with estimates of their sizes, and email it to companies to request prices. Know that windows with more panes require more work and cost more to clean. And it’s easier to work on newer windows that pop out or tilt in.
Companies usually clean both the inside and outside of your windows, and vacuum the sills. Some washers just do exteriors, but it’s not a great idea—you’ll still have visible streaks and dirt inside.
Make sure the company you hire to wash windows carries general liability and workers’ compensation insurance. Stick around while the work is being done, inspect it, and voice any complaints before workers depart.
