Window Cleaning

Professional Window Cleaning in Montreal — Crystal Clear Glass for Your Home or Business

Clean windows make a bigger difference than most people expect. They let in significantly more natural light, improve your view, and give your entire home or office a polished, well-maintained look. Dirty windows, on the other hand, are one of those things you stop noticing over time — until you see the difference a professional cleaning makes.

Sparkling Stays provides professional window cleaning for homes and businesses across Greater Montreal. We handle interior and exterior glass, screens, tracks, sills, and frames — delivering streak-free, crystal-clear results that transform the feel of your space.

Our Equipment and Products

Professional window cleaning requires the right tools — household products and paper towels simply don't deliver the same results. Our kit includes:

• Professional squeegees: Various sizes for different window types, delivering streak-free results that spray cleaners can't match
• T-bar applicators and scrubbers: For applying cleaning solution and loosening stubborn dirt
• Extension poles: For reaching high windows safely from the ground
• Microfiber cloths: For detailing edges, frames, and sills
• Razor scrapers: For removing paint specks, stickers, and hard water deposits without scratching glass
• Eco-friendly cleaning solutions: Biodegradable, non-toxic, no harsh fumes, and no residue that attracts future dirt
• Drop cloths and floor protection: We protect your floors, furniture, and windowsill items during interior cleaning
• Vacuum attachments: For cleaning tracks and removing loose debris before wet cleaning

When to Schedule Window Cleaning

The ideal window cleaning schedule depends on your property type and Montreal's seasonal conditions:

Residential Properties

• Twice a year (recommended): Spring and fall are the most popular times
• Spring (April–May): Removes winter grime — salt spray, road film, condensation stains, and the buildup from months of closed windows
• Fall (September–October): Cleans away summer pollen, dust, and insect residue before winter sets in. Clean windows also let in more of the low autumn and winter sunlight
• Quarterly: Ideal for homes near busy roads, construction zones, or with many trees
• Monthly: For homeowners who want consistently spotless windows year-round

Commercial Properties

• Monthly or biweekly: Storefronts, restaurants, and client-facing businesses benefit from frequent window cleaning
• Weekly: High-traffic retail locations, especially those on busy commercial streets
• After events or construction: One-time cleanings to address specific situations

Types of Windows We Clean

Montreal's housing stock includes a wide variety of window types, and we're experienced with all of them:

• Double-hung windows: The most common residential window type in Montreal
• Casement windows: Crank-operated windows common in newer homes and condos
• Sliding windows: Horizontal sliders found in many apartments and condos
• Fixed/picture windows: Large non-opening windows that maximize views
• Bay and bow windows: Multi-panel windows that extend outward
• Awning and hopper windows: Often found in basements and bathrooms
• French doors and sidelights: Glass panels alongside or as part of doors
• Skylights: Roof-mounted windows (accessible ones)
• Stained glass and decorative windows: Gentle cleaning with appropriate techniques
• Commercial plate glass: Large single-pane storefront and office windows

Pricing Context

Window cleaning rates depend on:

• Number of windows: We can quote per window or provide a flat rate for the whole property
• Window size and type: Large picture windows take more time than standard double-hungs
• Interior, exterior, or both: Full service (both sides) costs more than interior-only
• Screen cleaning: Included in most quotes but priced based on the number of screens
• Accessibility: Ground-level windows are straightforward; high or hard-to-reach windows require more time and equipment
• Condition: Windows that haven't been cleaned in years may require extra time for buildup removal
• Add-ons: Track detailing, frame cleaning, and specialty glass treatment

We provide transparent quotes before any work begins. No surprises.

Montreal-Specific Window Cleaning Tips

Montreal's climate creates unique challenges for window maintenance:

• Winter salt spray: Cars and snowplows kick up salt and calcium chloride that lands on exterior windows, especially those facing streets. This creates a cloudy film that's hard to remove with household products. Professional cleaning in spring is essential.
• Pollen season (April–May): Montreal's trees — especially birch, maple, and ash — produce massive amounts of pollen that coats exterior window surfaces. A post-pollen cleaning in late May or June makes a dramatic difference.
• Condensation and ice: During winter, condensation between panes (if you have older double-glazed windows) and ice buildup on interior surfaces can leave water stains. We treat these during spring cleaning.
• Construction dust: Montreal's perpetual construction projects create airborne dust that settles on exterior windows. If your property is near a construction zone, you may need more frequent exterior cleaning.
• Hard water stains: Some areas of Montreal and the South Shore have harder water that leaves mineral deposits on windows from sprinkler systems or rain runoff. We use specialized solutions to remove these deposits.
• Storm windows: Many older Montreal homes have storm windows that are installed seasonally. We can clean both the primary windows and storm windows during the seasonal changeover.

Frequently Asked Questions

Q: How often should I have my windows professionally cleaned?

For most residential properties, twice a year (spring and fall) is ideal. If you live near a busy road, a construction zone, or have lots of trees, quarterly cleaning provides better results. Commercial storefronts typically benefit from monthly or biweekly cleaning.

Q: Can you clean windows in winter?

We can clean interior windows year-round. Exterior window cleaning is best done in temperatures above freezing. We typically schedule exterior work between April and November. If you need interior-only cleaning during winter, we're happy to accommodate.

Q: Will window cleaning damage my window seals or frames?

No. Our techniques and products are safe for all window types, including vinyl, wood, aluminum, and painted frames. We use non-abrasive methods and avoid high-pressure water that could compromise seals.

Q: How long does window cleaning take?

A typical house with 15-20 windows takes 2 to 4 hours for full interior and exterior cleaning. A small apartment (6-10 windows) takes 1 to 2 hours. Larger homes or commercial properties take longer — we'll provide a time estimate with your quote.

Q: Do I need to move things off my windowsills?

We ask that you remove fragile or valuable items from windowsills before our arrival. We'll work around plants and sturdy items, but clearing the sills gives us better access and protects your belongings.

Q: Can you remove hard water stains or mineral deposits?

Yes. We have specialized solutions for hard water stains, mineral buildup, and calcium deposits. Severe buildup may require a restoration treatment, which we can assess during our visit.

Q: Do you clean high-rise condo windows?

We clean interior windows on any floor. Exterior windows on upper floors of high-rises typically require specialized rope access or swing stage equipment, which is usually coordinated by your condo building's management. We can clean exterior windows that are accessible from balconies or with standard extension equipment.

Q: Can I add window cleaning to my regular home cleaning visit?

Yes. Many clients add window cleaning as a seasonal add-on to their recurring cleaning plan. We recommend doing this in spring and fall for the best results.
