Window Cleaning Cost for a Mirabel Home in 2026
An exterior window clean for a house in Mirabel runs from $179 to $409 before taxes with Altara, set by the number of windows rather than by the hour. A bungalow in Saint-Janvier with 6 to 10 windows sits in the $249 tier, a two-storey family home in Domaine-Vert Nord with 11 to 15 windows is $329, and the large new builds with more than 20 windows get a custom quote. Interior glass, screen washing and track cleaning are optional add-ons on top of the flat rate.
Mirabel is a big, spread-out city, and the houses range from century farmhouses in Sainte-Scholastique to brand-new two-storey homes near Highway 15. This guide walks through the tiers, what is and is not part of the price, and the Mirabel-specific details that change the quote.
The flat-rate tiers
You count the windows on your house, choose the tier that matches on the pricing page, and book. There is no in-home estimate for a typical house. The current exterior rates for standard residential windows in Greater Montréal are:
- 1 to 5 windows (pied-à-terre or small condo): $179
- 6 to 10 windows (compact home): $249
- 11 to 15 windows (standard home): $329
- 16 to 20 windows (full home): $409
- 20 or more windows (larger home or estate): custom quote
Prices are in Canadian dollars and do not include GST and QST. One window is one opening in the wall. A double-hung window counts once, a three-panel slider counts once, and a patio door counts as one window. If your count lands on the edge of a tier, send the number through the contact form and the team will confirm which one applies before you pay anything.
Why Mirabel homes often land in the upper tiers
Newer subdivisions in Mirabel, particularly Domaine-Vert Nord, Mirabel-en-Haut and the growth around Saint-Augustin, were built with a lot of glass. A two-storey home from the last fifteen years often has a double-height window wall in the great room, transoms over the front door, a bay in the dining room and full-width sliders onto the deck. Count carefully: a house that looks like a 12-window home from the street frequently reaches 17 or 18 once you add the back and the sides.
Older houses in Saint-Canut, Saint-Hermas or along the rangs usually have fewer, smaller windows and fit the $249 or $329 tier. Farmhouses with a converted barn or a detached garage with windows can ask for those buildings to be included; they count toward the total, so mention them when you book.
Height is rarely the issue. The water-fed pole works from the ground up to three storeys, which covers almost every house in the city, including the tall great-room glass. A home set into a slope with a walkout basement that pushes the back wall past three storeys, or glass tucked under a deep roof overhang, gets a site visit before a price is given.
What you get for the tier price
The flat rate is for the outside of the house. On a standard visit the crew handles:
- the exterior face of every window in your count,
- frames and sills, scrubbed with the same soft brush,
- screens rinsed in place while the glass is being washed.
The water is pure deionized water, which matters more in Mirabel than in most of Greater Montréal. A large share of the city is outside the municipal water network and runs on wells, and well water here is often hard. If a crew washed your windows with that water, every drop would leave a mineral spot as it dried. Deionized water has nothing dissolved in it, so it dries clear and leaves no soap behind to attract the next layer of dust.
Add-ons and separately quoted work
Several things are not in the flat rate. Knowing them ahead of time makes it easier to compare quotes from different companies:
- Interior glass. A paid add-on done by hand with a squeegee and cloths. It can be booked any month, including winter.
- Screen removal and washing. The in-place rinse clears normal dust. Screens that have caught a season of pollen from the surrounding fields are better removed and washed, which is an add-on. Altara does not repair screens, but the crew points out tears so you can have them fixed.
- Track cleaning. Vacuuming and wiping the sliding tracks, added to an interior clean.
- Quoted on their own: skylights, solariums, heavy mineral stains, and post-construction cleanup.
Two of those come up more often in Mirabel than elsewhere. Heavy mineral staining is common on homes with well-fed lawn sprinklers that hit the lower windows all summer; after a few seasons the glass carries white rings that a normal pass will not lift. And post-construction cleanup is a frequent request in the newer sectors, where windows arrive with stucco splatter, silicone smears, paint overspray and the sticker residue from the manufacturer. Both need different tools and more time, so they are priced after the crew has seen the glass.
Dust, fields and gravel
Mirabel sits in an agricultural zone, and that shows on the windows. Spring tilling and fall harvest put fine soil in the air, and homes along gravel rangs get a film of road dust after every dry week. None of this changes the price of a visit, but houses backing onto active fields or on unpaved roads tend to look good for a shorter stretch than a similar house in a paved subdivision.
How recurring service lowers the per-visit price
The only discounts Altara gives are for recurring schedules:
- Quarterly: 10% off each visit
- Bi-monthly: 15% off each visit
- Monthly: 20% off each visit
For a full home in the $409 tier, quarterly service brings each exterior visit to about $368 before taxes, and monthly service to about $327. Exterior work follows the season, roughly March through November, so a quarterly plan usually means three exterior visits across spring, summer and fall. Interior cleaning is not weather-dependent and can keep going through winter.
Spring-and-fall (bi-annual) and once-a-year programs carry no discount. What they include is an automated reminder when the next visit is due, so the booking does not slip. For a Mirabel home away from the fields, twice a year is usually enough: one clean in spring for salt film and pollen, one in fall to clear the summer dust before the short days.
Reading another company's quote
Prices across the North Shore vary mostly because each company draws the line in a different place. Check whether a quote covers the exterior, the interior or both, whether it is flat or hourly, what happens to screens and tracks, whether taxes are in the figure, and what the company does about a streak. With Altara, report a streak within 24 hours and the crew returns at no charge.
The last exterior window of the season
Late October is the end of the exterior season in Mirabel. Nights are already near freezing in the rural sectors, and once frost stays on the glass into the afternoon, water-based exterior cleaning pauses until March. If the summer dust is still on your windows, book now so the visit lands on a mild day. Interior glass, screens and tracks can be booked any time through the winter.
Frequently asked questions
How much does window cleaning cost for a new two-storey house in Mirabel?
Most new two-storey homes in Domaine-Vert Nord or Mirabel-en-Haut have 16 to 20 windows once the back and sides are counted, which puts them in the $409 exterior tier before taxes. Homes with more than 20 windows get a custom quote. If the house is fresh from the builder and the glass still has stucco or silicone on it, that first clean is quoted separately as post-construction work.
Does Altara charge more for homes on well water?
No. The crew brings its own deionized water, so the hardness of your well has no effect on the price of a standard clean. Well water only becomes a cost factor when sprinklers have left heavy mineral rings on the glass over several seasons; removing those is a separate quote.
Can the price include a detached garage or a barn?
Yes. Count the windows on any building you want cleaned and add them to the total. If the combined count pushes you past 20 windows, you will receive a custom quote instead of a fixed tier.
Is interior cleaning part of the flat rate?
No. The flat rate covers exterior glass, frames and sills, with screens rinsed in place. Interior glass, screen removal and washing, and track cleaning are optional add-ons you select when you book.
