What Services Do You Offer?

Window cleaning companies often provide a range of services beyond just washing windows. Ask about:

• Interior and exterior window cleaning

• Screen cleaning

• Frame and sill cleaning

• Hard water stain removal

• Gutter cleaning or pressure washing (if applicable)

  
  

Knowing the full scope of services helps you understand what you can expect and whether the company can meet your specific needs. For example, if you want your window screens cleaned as well, confirm that this is included or available as an add-on.

Is Your Window Cleaning Service Licensed and Insured?

A reputable window cleaning company should have proper licensing and insurance. This protects you from liability if accidents happen on your property. Ask for proof of:

• Liability insurance

  
  

If a cleaner is not insured, you could be responsible for any damage or injuries that occur during the job. Always verify these credentials before hiring.

What Is Your Pricing Structure?

Understanding how a window cleaner charges helps avoid unexpected costs. Common pricing methods include:

• Per window or per pane

• Per hour

• Flat rate for the entire job

  
  

Ask if the price includes all fees, such as travel or equipment costs. Also, clarify whether there are extra charges for difficult-to-reach windows or special treatments like stain removal. Getting a detailed written estimate is best.

How Do You Handle Difficult or High Windows?

Some windows require special equipment or techniques, especially on multi-story buildings or hard-to-access spots. Ask:

• Do you use ladders, scaffolding, or water-fed poles?

• Are there extra fees for high or hard-to-reach windows?

• How do you ensure safety during these jobs?

  
  

A professional company will have the right tools and training to clean safely and effectively at height.

What Cleaning Products Do You Use?

The type of cleaning solutions matters for both the environment and the condition of your windows. Ask about:

• Are your products eco-friendly or biodegradable?

• Do you use chemicals that could damage window frames or tinting?

• Can you accommodate allergies or sensitivities?

  
  

Many companies now offer green cleaning options that are safe for plants, pets, and people.

How Often Should I Have My Windows Cleaned?

Frequency depends on your location, weather, and personal preference. Ask the cleaner for recommendations based on your situation. For example:

• Homes near busy roads may need more frequent cleaning due to dirt and pollution

• Coastal areas might require regular washing to remove salt buildup

• Commercial buildings often schedule monthly or quarterly cleanings

  
  

Understanding the ideal schedule helps maintain your windows’ appearance and longevity.

Can You Provide References or Reviews?

A trustworthy window cleaning service should have satisfied customers willing to share their experiences. Request:

• References from recent clients

• Online reviews or testimonials

• Before-and-after photos of previous work

  
  

Checking these helps you gauge the company’s reliability and quality.

What Is Your Cancellation or Rescheduling Policy?

Life happens, and sometimes appointments need to change. Ask about:

• How much notice is required to cancel or reschedule?

• Are there any fees for last-minute changes?

• What happens if the weather prevents cleaning on the scheduled day?

  
  

Clear policies prevent misunderstandings and help you plan better.

How Long Will the Job Take?

Knowing the estimated time frame helps you plan your day. Ask:

• How many windows can you clean per hour?

• Will the job require multiple visits?

• Do you clean during business hours or evenings/weekends?

  
  

This is especially important for commercial properties where downtime matters.

Do You Guarantee Your Work?

A company confident in its service will offer some form of guarantee or warranty. Ask:

• What happens if I’m not satisfied with the cleaning?

• Will you return to fix any issues at no extra cost?

• How long does the guarantee last?

  
  

A clear satisfaction policy shows the company stands behind its work.
