Professional Window Washing in Montréal: Is It Worth It?

For most Montréal homes, professional window cleaning is worth it compared with doing it yourself, mainly because of time, ladder safety and a streak-free finish. Altara's exterior flat rate runs from $179 for 1 to 5 windows to $409 for 16 to 20 windows, and a DIY job on a whole house typically costs you a full day plus the tools. If you only have a few ground-floor windows, doing them yourself can make sense.

Montréal's winter grit, spring pollen and summer dust make windows dirty fast, and getting them truly clean takes more than a bucket of soapy water.

That story is common, and it makes a point: some jobs are better left to the pros, especially when the result is something you look through every single day. For homeowners in Montréal, the city's blend of winter grit, spring pollen and summer dust means windows get dirty fast. Getting them truly clean, without streaks, takes more than a bucket of soapy water and good intentions.

Why DIY Window Cleaning is Often a Losing Battle

Cleaning windows yourself sounds simple enough on paper. Grab some glass cleaner, a roll of paper towels, and go to town. The reality, especially for a whole house, is more complicated. First, there's the equipment. For anything beyond ground-floor windows, you're looking at ladders. They're cumbersome, can be dangerous if not used correctly, and often don't give you the reach or stability you need. Trying to balance a bucket, a squeegee and yourself on a rung? No thanks.

Then there's the cleaning itself. Store-bought glass cleaners often leave a film that attracts dust faster. Tap water contains minerals that leave white spots and streaks when they dry. You scrub and wipe, thinking you've got it, only for the sun to reveal a mosaic of missed spots. And the screens? Most people leave them in or give them a quick hose-down, which does little for the dirt and pollen that block light and air. The tracks collect years of grit, dead bugs and debris, making windows hard to open. They're the most common DIY frustration, because they're nearly impossible to get truly clean without a vacuum and the right tools.

The time commitment is another big factor. A full house of windows, inside and out, can easily eat up an entire day or a weekend if you do it properly. That's time you could spend along the Lachine Canal, exploring the Plateau or simply relaxing with your family.

What Does Professional Window Washing in Montréal Actually Offer?

The point of paying someone else is to get a result you can't easily get on your own: streak-free glass, no smudges, no water spots, no film. Here's what Altara Residential Window Cleaning offers:

• Exterior glass, frames and sills (flat rate): Cleaned using a pure-water system. Deionized water, fed through water-fed poles, dries spot-free because the minerals that cause streaks have been removed. No detergent is needed, so there's no sticky residue to attract new dirt. Screens are rinsed in place during this pass.
• Interior glass (add-on): Cleaned with a residential-safe glass cleaner, squeegee and microfibre for a clean finish. Available at extra cost, any time of year.
• Screen removal and washing (add-on): Each screen is removed, washed to clear accumulated dust and pollen, and reinstalled. It makes a real difference to how much light and air comes through.
• Track cleaning (add-on): Tracks are vacuumed out and wiped, which helps windows slide smoothly and look finished.

Skylights, solariums, heavy mineral staining and post-construction cleanup are quoted separately. Imagine looking out at the city, or your garden, through glass that looks like it isn't there. That's the standard to expect.

Is Professional Window Washing in Montréal Worth the Cost?

This is the question every homeowner asks, and for most homes the answer is yes. When you factor in the time saved, the frustration avoided, not having to climb ladders, and a better result, the cost is reasonable for what you get. You're paying for equipment, technique and a streak-free finish.

Think about it: what's your time worth? If you spend 4 to 6 hours struggling with ladders and getting mediocre results, that's half a day gone. A crew with the right tools finishes the job efficiently, and Altara backs every visit with a guarantee: every window is spot-checked before the crew leaves, and if you see a streak afterwards, contact Altara within 24 hours and the crew returns to re-clean at no charge.

For homes across Montréal, from Plateau triplexes to detached homes in the West Island, clean windows make a big visual difference, inside and out. With Altara, you pick your window-count tier on the pricing page and book online. No in-home visit just to get a price.

Altara's Approach to Residential Window Cleaning

Altara focuses on residential properties in Greater Montréal. The flat rate covers the exterior, and you add interior glass, screens or tracks when you want them, so you only pay for what you choose. Annual (spring) and spring-and-fall programs come with an automated reminder before your next visit. If you want more frequent service, quarterly visits get 10% off, bi-monthly 15% and monthly 20%. Exterior work runs roughly March to November.

The water-fed pole reaches up to three storeys from the ground, which covers most homes, including many triplexes. If you have a taller home or windows that are particularly difficult to reach, like the high panes on some of the older, grander homes in Outremont or Westmount, Altara does a site visit before pricing.

Whoever you hire, it's fair to ask what coverage they carry and how they handle a missed spot.

Frequently asked questions

Is professional window cleaning worth it, or should I do it myself?

For a whole house, professional cleaning is usually worth it: it saves most of a day, avoids ladder work and leaves fewer spots than tap water and store cleaners. Doing a few ground-floor windows yourself is a reasonable choice if you already own the tools.

How much time does professional window washing save compared with doing it yourself?

Doing every window in a house properly, inside and out, can easily take a full day or even a weekend. A trained crew with water-fed poles and the right tools usually finishes in a fraction of that time, and without anyone in the household climbing a ladder.

Why do windows streak when I clean them myself?

Store-bought glass cleaners often leave a film that attracts dust, and tap water leaves mineral spots as it dries. Professionals clean exterior glass with deionized pure water that dries spot-free, and finish interior glass with a squeegee and microfibre.

Does Altara clean three-storey homes in Montréal?

Yes. The water-fed pole reaches up to three storeys from the ground. Taller homes or hard-to-reach windows, such as the high panes on some older homes in Outremont or Westmount, get a site visit before pricing.

How often should a Montréal home have its windows professionally cleaned?

Twice a year, spring and fall, suits most homes after Montréal's snowy winters and pollen-heavy springs, and the program sends automated reminders. Some homeowners prefer a single spring visit, and those who want more frequent service get discounts on quarterly, bi-monthly or monthly visits.
