Interior & Exterior Window Cleaning

Professional Glass Maintenance Businesses

Our interior & exterior window cleaning service removes smudges, dust, and grime that build up over time. We use purified water and gentle cleaning techniques that remove dirt without damaging the glass or surrounding areas. Unlike regular cleaning crews, our window specialists have the training and equipment to reach high windows and tackle tough stains that regular maintenance might miss.


We know that running a business keeps you busy enough without worrying about streaky windows. Many of our Pittsburgh clients tell us that after our service, they notice an immediate improvement in their building's appearance – and some even report lower lighting costs as more natural sunlight enters their space. Give your business the professional image it deserves with windows that truly shine.

Frequently Asked Questions

Window cleaning services can be confusing to navigate. Here are answers to the most common questions our clients ask about our professional window cleaning services in Pittsburgh.

  • What factors influence the cost of professional window cleaning services?

    The price of our window cleaning services depends on several key factors. The number and size of windows directly impact the total cost, as larger buildings naturally require more time and resources.


    Building height is another significant factor, as high-rise facilities require specialized equipment and safety measures. We adjust our pricing based on accessibility challenges like landscaping obstacles or difficult-to-reach windows.


    The level of dirt and grime also affects cost. Windows that haven't been cleaned in years need more intensive work than those on a regular maintenance schedule.

  • Are there different methods used by professionals for interior versus exterior window cleaning?

    We absolutely use different techniques for interior and exterior windows. For interior cleaning, we typically use less aggressive methods with milder cleaning solutions to protect indoor air quality and your furnishings.


    Exterior windows face harsh weather conditions and collect more dirt, requiring stronger cleaning agents and specialized tools. For high-rise buildings, we employ professional-grade equipment like water-fed poles and sometimes even rope access techniques.


    Our team carefully selects the right approach based on window type, building height, and environmental considerations.

  • What should I expect when hiring commercial janitorial services for window cleaning?

    When you hire our Pittsburgh Commercial Janitorial Services, we start with a thorough assessment of your facility's window cleaning needs. We'll provide a detailed quote outlining scope, timeline, and cost.


    On cleaning day, our uniformed professionals arrive with all necessary equipment and work efficiently to minimize disruption to your business operations. We use drop cloths and take precautions to protect your property.


    After cleaning, we conduct a quality inspection and walk-through with you to ensure your complete satisfaction with the results.

  • What certifications or standards should a reputable window cleaning service meet?

    Reputable window cleaning services should have proper liability insurance and workers' compensation coverage to protect both their employees and your property. This is non-negotiable in our industry.


    Our technicians receive training in OSHA safety standards, especially for high-rise window cleaning operations. We follow industry best practices established by the International Window Cleaning Association (IWCA).


    We also maintain compliance with all local Pittsburgh regulations regarding commercial services and safety standards.

  • How often should commercial windows be professionally cleaned?

    Most commercial properties benefit from professional window cleaning 2-4 times per year. However, the ideal frequency depends on your specific situation.


    Businesses in high-traffic urban areas or near construction sites typically need more frequent cleaning due to increased dirt and pollution. Restaurants, healthcare facilities, and retail stores often clean windows monthly to maintain a pristine appearance.


    We can help you establish a customized maintenance schedule based on your building's location, weather exposure, and budget considerations.

  • What additional services can I expect from a company specializing in commercial window cleaning?

    Beyond standard window cleaning, we offer screen cleaning and repair services to extend the life of your window systems. We can also handle hard water stain removal and restoration of damaged glass surfaces.


    Our team provides cleaning for related architectural elements like skylights, glass partitions, and atrium glass. For complete facility maintenance, we offer complementary services including gutter cleaning and pressure washing of building exteriors.


    We create custom-tailored service packages based on your specific facility needs and budget requirements.
