DIY vs professional window cleaning: an honest cost comparison

We are biased, so here are the numbers

We clean windows for a living, so of course we think hiring a pro is worth it. But plenty of people clean their own windows well, and for some homes it genuinely makes sense. This guide lays out the real time, cost and risk so you can decide for yourself.

What a DIY setup costs

To get results close to professional quality, you need more than paper towels and blue spray. A realistic starter kit looks like this:

Professional squeegee with replacement rubber: $25 to $40
Microfiber strip applicator: $20 to $30
Bucket that fits a 14-inch applicator: $15
Scrubbing pads and detail towels: $20
Extension pole for first-floor high glass: $40 to $70
Stabilized extension ladder for second story: $250 to $450

How long it actually takes

A practiced professional cleans a standard window, inside and out, in about 6 to 8 minutes. Most homeowners take 15 to 25 minutes per window the first few times, because squeegee technique takes practice and streaks mean doing panes twice.

For a single-story home with 20 windows, plan on a full Saturday for inside and outside, plus screens. For a two-story home with 30 windows, it is realistically a two-weekend project once you add ladder moves, screens and tracks.

The part nobody wants to talk about: ladders

Falls from ladders send hundreds of thousands of Americans to emergency rooms every year, and home maintenance is one of the most common reasons. Second-story window cleaning is exactly the kind of task where people overreach, set a ladder on uneven ground or lean against glass.

If your home is single story, DIY risk is low. If you have second-story glass, high stairwell windows or a sloped lot, we strongly suggest leaving those to someone insured with the right equipment, even if you do the ground floor yourself.

What professional cleaning costs

In the Sacramento area, a single-story home with 20 windows typically runs $189 to $259 for exterior only, or around $299 to $389 inside and out. A two-story home with 30 windows is usually $349 to $529 for a full inside and outside clean with screens.

On a twice-a-year plan, that works out to roughly $50 to $90 per month averaged over the year for most homes, with no gear to store and no weekends lost.

When DIY makes sense

Single-story homes with easy access and few windows
You enjoy the work and have time to learn technique
Windows are cleaned often enough that there is no hard water build-up
You only want to spot-clean a few problem windows between pro visits

When hiring out makes sense

A hybrid approach works well for many families: hire a pro for the big spring and fall cleans, then touch up the kitchen slider and front door glass yourself in between. Whatever you choose, our instant estimator will give you a real number in about 30 seconds.
