If you live in Westmount, you know that keeping your home looking its best is part of the lifestyle. From the historic architecture to the modern renovations, your windows play a huge role in how your home feels and looks. But let’s be honest: cleaning windows is a chore that most homeowners dread.
At Flip et Bulles, we’ve spent years helping homeowners across Montreal, Kirkland, and the West Island get that crystal-clear view they deserve.

1. It’s Not Just About the Glass
When most people think of residential window cleaning, they only think of the glass. However, a truly professional service covers much more. If you only clean the glass and leave the frames and sills dirty, the next time it rains, all that dirt will wash right back onto your clean windows.
A comprehensive service should include:
- Sills and Tracks: Dust and debris often build up here, which can lead to mold or even damage the window’s opening mechanism.
- Frames: Cleaning the exterior frames prevents long-term staining and improves your home's curb appeal.
- Screens: Dust-clogged screens block airflow and make your windows look gray from the outside.

2. The Right Tools Make a Massive Difference
You might be tempted to grab a bottle of blue spray and a roll of paper towels, but that’s the fastest way to get streaks. Professional window cleaners use specialized tools that ensure a flawless finish.
We use professional-grade squeegees, microfiber applicators, and often "water-fed pole" systems for high-reach windows. These poles use purified water to scrub away grime and leave a spot-free finish without needing a ladder for every single pane. This is especially important for the large, multi-story homes common in Westmount and Laval.
3. Professional Technique vs. DIY
Have you ever spent an entire Saturday cleaning your windows only to see streaks as soon as the sun hits them? That’s because professional window cleaning is a skill. Our technicians are trained to use specific motions to "cut in" the edges and pull the water off the glass without leaving a single line behind.
Beyond the aesthetics, professionals know how to handle different types of glass. Whether you have delicate older windows in a Westmount heritage home or modern energy-efficient double-paned glass in Kirkland, we know exactly how much pressure to apply and which solutions to use.

4. Safety Should Be a Top Priority
Westmount is famous for its hills and multi-story houses. Cleaning windows on the second or third floor requires tall ladders and a lot of balance. Every year, thousands of homeowners are injured in ladder-related accidents.
When you hire Flip et Bulles, you aren’t just paying for clean glass; you’re paying for safety. We have the experience and the equipment to reach those difficult spots safely, so you don’t have to risk a fall. We are also fully insured, which gives you peace of mind while we work on your property.
5. Eco-Friendly Solutions are Better for Everyone
At Flip et Bulles, we believe in keeping your home beautiful without harming the environment. Many old-school cleaning solutions contain harsh chemicals that can run off into your garden or harm your pets.
We prioritize state-of-the-art, eco-friendly cleaning solutions. These are biodegradable and safe for your family, your plants, and the local Westmount ecosystem. Plus, high-quality eco-friendly soaps actually help keep your windows cleaner for longer by not leaving behind a sticky residue that attracts dust.
6. Window Cleaning Extends the Life of Your Windows
Believe it or not, glass is porous. Over time, hard water minerals, oxidation, and environmental pollutants can seep into the pores of the glass. If left untreated, this can cause permanent etching or "cloudiness" that no amount of cleaning can fix.
Regular residential window cleaning removes these corrosive elements. By maintaining a regular schedule, usually twice a year, you can prevent the need for expensive window replacements down the line.
7. The Connection Between Windows and Gutter Cleaning
If your windows look dirty shortly after a cleaning, your gutters might be the culprit. When gutters are clogged with leaves and debris, rainwater overflows. This dirty, overflowing water splashes against your windows, leaving behind mud and organic stains.
In areas like Kirkland and the West Island, where trees are abundant, we highly recommend combining your window cleaning with gutter cleaning. Keeping your gutters clear ensures that rainwater is directed away from your clean windows and your home's foundation.

8. Gutter Guard Installation: A Smart Investment
Tired of cleaning your gutters every spring and fall? Many Westmount and Laval homeowners are opting for gutter guard installation. These perforated aluminum covers allow water to flow through while keeping leaves and twigs out.
Installing gutter guards can:
- Reduce Maintenance: You won't need to clean your gutters as often.
- Protect Your Windows: No more overflow splashing onto your glass.
- Prevent Pests: Dry, debris-free gutters are less attractive to birds and rodents.

9. Seasonal Timing is Key
In Montreal, timing is everything. We generally recommend a deep clean in the spring to remove the salt and grime from winter, and another in the fall to prepare for the darker months ahead.
- Spring Cleaning: Removes the salt that can corrode your frames.
- Fall Cleaning: Maximizes the limited sunlight we get during the winter.
Book early, especially in Westmount and the West Island, as the "patio season" rush can fill up schedules quickly. You can read more about preparations in our West Island guide.
10. Commercial Window Cleaning Matters Too
Do you own a business in Westmount or Laval? First impressions are everything. A storefront with streaky, dirty windows can subconsciously turn customers away. Residential techniques don't always translate to commercial glass, which often faces higher levels of road grime and exhaust. We offer tailored commercial window cleaning packages to ensure your business reflects the quality of the services you provide.
Pro Tips for the Best Results
To get the most out of your professional service, here are a few expert tips:
- Clear the Area: Move any potted plants or outdoor furniture away from the windows before the crew arrives.
- Check the Weather: Don't worry about a light drizzle. Rainwater is actually quite pure; it's the dirt on the window that makes it look "spotted" after a storm. However, we will reschedule if there is high wind or heavy rain for safety reasons.
- Interior Prep: If we are cleaning the insides, please clear the sills of any breakables or electronics.
- Frequency: For the best results, aim for a full interior/exterior clean once a year and an exterior-only clean once every six months.
