Understanding the Importance of Professional Window Cleaning

Windows are often called the eyes of a building, and like eyes, they need regular care to function optimally. Over time, windows accumulate layers of dirt, dust, pollen, bird droppings, and environmental pollutants that not only obstruct your view but can also cause permanent damage to the glass. At Cleaner-Kenya, we understand that clean windows do more than improve aesthetics—they allow more natural light into your spaces, contribute to energy efficiency, and create a healthier indoor environment.

Our crystal-clear window cleaning process has been developed and refined over years of serving homes and businesses throughout Nairobi and Kenya. We combine traditional techniques with modern innovations to deliver results that consistently exceed our clients' expectations.

Tools and Equipment We Use

Professional window cleaning requires specialized tools that the average homeowner simply doesn't have access to. Our technicians arrive at every job fully equipped with industry-leading equipment designed to handle windows of all types and sizes.

Cleaning Supplies That Make the Difference

The products we use are as important as our techniques. At Cleaner-Kenya, we've carefully selected cleaning supplies that are effective, safe for your family and pets, and environmentally responsible.

Our Step-by-Step Window Cleaning Process

Step 1: Initial Assessment and Preparation (10-15 minutes)

Every professional window cleaning job begins with a comprehensive assessment. Our technicians walk through your property, counting windows, noting their condition, and identifying any special challenges such as hard water stains, paint overspray, or damaged seals. This assessment allows us to determine the appropriate tools, cleaning solutions, and time required for your specific needs.

During preparation, we lay down protective coverings to safeguard your floors, furniture, and landscaping. We also remove any obstacles near windows, such as plants or decorative items, with your permission.

Step 2: Dry Brushing and Debris Removal (5-10 minutes per window)

Before introducing any water or cleaning solutions, we use soft brushes to remove loose dirt, cobwebs, dead insects, and other debris from the window surface, frames, and sills. This crucial step prevents dirt from turning into muddy streaks when wet cleaning begins. We pay special attention to corners and edges where debris tends to accumulate.

For windows with screens, we remove them carefully and clean them separately using a mild soap solution and soft brushes before rinsing and allowing them to air dry.

Step 3: Application of Cleaning Solution (2-3 minutes per window)

Once the dry cleaning is complete, we apply our professional cleaning solution generously across the entire window surface. The solution is applied using either a scrubber sleeve or a sponge applicator, working in overlapping horizontal or vertical strokes to ensure complete coverage.

For heavily soiled windows or those with hard water stains, we may allow the cleaning solution to dwell for several minutes. This dwell time allows the cleaning agents to break down stubborn deposits, making removal much easier and more effective.

Step 4: Scrubbing and Agitation (3-5 minutes per window)

With the cleaning solution applied, we use scrubbers or brushes to agitate the surface, loosening embedded dirt and grime. Our technicians use systematic patterns—typically starting at the top and working downward—to ensure no areas are missed.

Stubborn spots such as bird droppings, tree sap, or paint overspray receive special attention. For these problem areas, we may use specialized scrapers held at precise angles to lift the material without scratching the glass. Our experienced technicians know exactly how much pressure to apply for effective cleaning without causing damage.

Step 5: Squeegee Application (1-2 minutes per window)

The squeegee technique is where professional window cleaning truly distinguishes itself from amateur attempts. Our technicians use professional-grade squeegees with sharp, nick-free rubber blades to remove the cleaning solution and water in smooth, overlapping strokes.

We employ various squeegee techniques depending on window size and shape. For standard rectangular windows, we typically use the top-to-bottom method with slight overlaps. For smaller panes, we might use the fan method or swirl technique. The key is maintaining consistent pressure and angle throughout each stroke to prevent streaking.

After each stroke, we wipe the squeegee blade clean with a lint-free cloth to prevent transferring dirt back onto the glass.

Step 6: Detailing and Edge Work (2-3 minutes per window)

Even the most skilled squeegee work leaves small amounts of water along window edges and in corners. This is where detailing makes the difference between good and exceptional results. Using microfiber cloths or specialized detailing tools, our technicians carefully absorb any remaining moisture from edges, corners, and the bottom seal.

We also clean window sills, tracks, and frames during this stage, removing any dirt or cleaning solution that may have dripped down. This attention to detail ensures every aspect of your windows looks pristine.

Step 7: Frame and Sill Cleaning (2-4 minutes per window)

Clean glass is only part of the equation. Window frames, sills, and tracks accumulate their own share of dirt, pollen, and grime. We use appropriate cleaning solutions for different frame materials—whether vinyl, aluminum, or wood—to clean these areas thoroughly without causing damage or discoloration.

Tracks receive special attention as they often harbor accumulated dirt, dead insects, and other debris. We use specialized track cleaning tools and vacuums to remove this buildup, ensuring your windows open and close smoothly.

Step 8: Final Inspection and Touch-Ups (5-10 minutes)

Before considering any job complete, our team supervisor conducts a thorough final inspection of all cleaned windows. We view windows from multiple angles and lighting conditions to identify any spots, streaks, or missed areas. Any imperfections are immediately corrected.

We also inspect frames and sills to ensure they're clean and dry, and we verify that all screens have been properly reinstalled if they were removed during cleaning.

Average Duration of Our Window Cleaning Service

The time required for professional window cleaning varies based on several factors including the number of windows, their size and accessibility, the level of soiling, and whether interior and exterior cleaning are both requested.

For a typical residential home with 15-20 standard-sized windows, our complete interior and exterior cleaning service usually takes between 2 to 4 hours. A small apartment with 8-10 windows might be completed in 90 minutes to 2 hours, while larger homes with 30 or more windows could require 4 to 6 hours.

Commercial properties have their own timelines, often depending on building height and window quantity. A small office with 20-30 windows typically takes 3-4 hours, while larger commercial buildings are quoted on a case-by-case basis.

These timeframes include all steps of our process from initial assessment through final inspection, ensuring that nothing is rushed and every window receives the attention it deserves.
