Residential Window Cleaning

Commercial Window Cleaning

Window Cleaning for Clarity, Safety, and Property Appearance

We provide professional window cleaning services for residential and commercial properties across Toronto and the GTA, including interior window cleaning, exterior glass washing, frame detailing, and high-access window maintenance.

Windows are constantly exposed to dust, pollution, mineral deposits, moisture buildup, and environmental contaminants. Over time, these factors reduce natural light, affect visibility, and can even damage glass surfaces and window hardware.

Routine wiping removes only surface dirt, while professional window cleaning is required to eliminate stubborn residues, restore transparency, and protect glass integrity.

Leronzo Cleaning Group delivers structured window cleaning solutions for houses, apartments, offices, retail spaces, and multi-story buildings — using professional equipment, purified water systems, and streak-free cleaning techniques adapted to each property type.

Types of Window Cleaning Services We Offer

Different properties and window configurations require different cleaning approaches depending on height, accessibility, contamination level, and glass type.

Our window cleaning services are designed to provide flexible solutions for both routine maintenance and intensive restoration cleaning.

Clients can choose from a range of specialized window cleaning options, including:

House Window Cleaning
Condo & Apartment Window Cleaning
Commercial Window Cleaning
• Interior Window Cleaning
• Exterior Glass Washing
• Frame, Sill & Track Cleaning
• High-Access & Multi-Level Window Cleaning
• Post-Construction Window Cleaning

Each service is structured to ensure consistent results, safe cleaning methods, and predictable outcomes for every window type.

How Professional Window Cleaning Differs from Basic Cleaning

Cleaning windows properly requires specialized tools and techniques that go far beyond basic wiping or household cleaning methods.

Glass surfaces accumulate microscopic mineral deposits, airborne pollutants, grease particles, and hard-water stains that cannot be removed with standard cleaning solutions.

Professional window cleaning uses controlled water purification systems, streak-free detergents, and precise drying methods to safely remove contaminants without scratching glass, damaging seals, or leaving residue.

Our cleaning process focuses on glass assessment, stain treatment, safe access planning, and systematic cleaning procedures to ensure long-lasting clarity and surface protection.

Choosing the Right Window Cleaning Service

Selecting the correct cleaning level depends on window condition, exposure to weather, frequency of maintenance, and the presence of stains or buildup.

Routine maintenance cleaning helps preserve clarity and prevent dirt accumulation, while deep cleaning is recommended for neglected windows, construction residue, mineral deposits, or heavily exposed commercial façades.

Understanding these differences ensures the most effective cleaning method is chosen for each property.

Safe, Insured, and Professional Window Cleaning

Leronzo Cleaning Group provides fully insured window cleaning services performed by trained specialists using professional-grade equipment and safe cleaning solutions.

Got Questions? Let’s Clear Things Up

01. What types of commercial properties do you service?
check

We provide scalable services for businesses of all sizes, including office towers, retail storefronts, shopping malls, restaurants, medical facilities, warehouses, and institutional buildings. Our crews and equipment are equipped to handle anything from a small shop front to a multi-story façade.

02. How do you minimize disruption to our daily business operations?
check

We are experts in non-disruptive cleaning. We work with you to create a schedule—often during off-hours, nights, or weekends—that avoids peak customer or employee activity. For storefronts, we can work in short, efficient blocks. Our crews are efficient, professional, and mindful of your workspace.

03. What safety standards and insurance do you have for commercial projects?
check

We operate to the highest safety standards. We are fully licensed and insured with comprehensive general liability and WSIB coverage. Our teams are trained in fall protection, equipment use, and site-specific safety protocols to ensure every project is completed without incident.

04. Can you handle large-scale projects with complex access needs (e.g., rope access, swing stages)?
check

Yes, we have the capability and partnerships to manage complex projects. For high-rise or complex façades, we employ or subcontract certified technicians using boom lifts, swing stages, or controlled descent (rope access) systems as required, always following strict safety regulations.

05. Do you offer service contracts for regular maintenance?
check

Yes, we specialize in creating customized maintenance programs. Regular scheduled cleanings (e.g., monthly, quarterly, bi-annually) are the most cost-effective way to maintain a pristine professional image, prevent buildup, and ensure your property always looks its best for clients and employees.

06. What is included in a standard commercial cleaning versus a detailed facade cleaning?
check

A standard cleaning focuses on the glass for clarity. A detailed or building restoration clean is more comprehensive, including window frames, metalwork, soffits, entrance canopies, and exterior light fixtures. We can provide a quote for either service level based on your property's needs.
