Commercial Window Cleaning: 5 Questions to Ask When Hiring a Pro

Oct 13, 2025

Shiny windows don’t just improve the look of a building—they reflect professionalism, attention to detail, and care for employees and customers. But when it comes to commercial high rise window cleaning, not all services are the same. Whether you’re hiring for a small office, a retail store, or a high rise building window cleaning project, asking the right questions ensures you get safe, reliable, and high-quality results.

Here are five key questions to ask before signing a contract with a window cleaning company.


1. What Experience Do You Have With High Rise Window Cleaning?

Cleaning a home’s windows is not the same as high rise building cleaning. Skyscraper windows require specialized skills, equipment, and training.

Ask:

  • How many years have you been offering high rise window cleaning?

  • Do you have certified technicians for rope access and safety?

  • What kind of insurance do you carry?

Because the number one hazard faced by professional window cleaners is working at height, it’s essential to hire a team that knows how to handle the risks.


2. How Do You Determine Window Cleaning Prices?

Every company calculates window cleaning prices differently. Some use a window cleaning pricing guide, while others charge based on square footage, building type, or accessibility.

Questions to ask:

  • How much does window cleaning cost for commercial properties?

  • Do you offer window cleaning prices per window or per project?

  • Are window cleaning company prices higher for skyscrapers or specialty glass?

Transparency matters. A good provider should give you a clear window cleaning quote upfront, with no hidden fees.


3. What Is Included in the Window Cleaning Services?

Not all window cleaning services prices include the same things. Some companies only handle exterior panes, while others include:

  • Interior window cleaning

  • Frame and sill wiping

  • Exterior window cleaning services for hard-to-reach areas

  • Screen and track cleaning

Be specific when asking how much to charge for window cleaning inside and out, since interior work often requires more labor.

If you’re researching window washers in my area, compare services as much as rates. The lowest window washing prices aren’t always the best deal.


4. How Do You Ensure Safety During High Rise Building Window Cleaning?

Safety should always be a priority. Whether it’s building window cleaning for an office park or skyscraper window washing, the risks are real.

Ask about:

  • Certifications for high rise cleaning

  • Harness and rope access systems

  • Weather and wind safety policies

  • Emergency procedures

Remember, the average price for window cleaning may be higher for companies with stronger safety standards—but the peace of mind is worth it.


5. Can You Provide References or Reviews?

One of the best ways to judge a commercial window cleaning service is through feedback from past clients. Ask for references, especially from businesses in your industry.

Also check online for:

  • Reviews mentioning how much do window cleaners charge and whether the pricing was fair

  • Comments on reliability, punctuality, and quality

  • Experiences with window washers residential vs. commercial

If you search window washers near me prices, you’ll likely find a wide range of window cleaning rates. Real customer reviews can help you see if the value matches the cost.


Understanding Window Cleaning Cost

To help set expectations, here are the most common pricing factors:

  • Size of the building – More windows = higher cost

  • AccessibilityHigh rise window cleaning requires more equipment and training

  • Frequency – Regular contracts lower the window cleaning services cost over time

  • Type of glass – Specialty or tinted glass may raise window cleaning rates

So, how much is window cleaning really? The average price for window cleaning varies, but asking for multiple commercial window cleaning quotes ensures you pay a fair rate.

If you’re on the business side, knowing how much should I charge to clean windows or how to charge for window cleaning is crucial for profitability. Many professionals start by calculating window cleaning cost per window and adjust for interior, exterior, and high-rise challenges.

  • Deliver streak-free results

  • Follow safety protocols for high rise window cleaning

  • Provide accurate window cleaning company prices with contracts

  • Save businesses time and liability
