Professional Residential & Commercial Window Cleaning Services
Transform your view with crystal-clear, streak-free window cleaning. Fully insured, trained in-house crews utilizing deionized water-fed poles and eco-safe methods across Greater Montreal.

The Professional Difference
Crystal-Clear Windows Without Streaks, Smudges, or Film
Standard window cleaning often relies on tap water and basic squeegees, leaving behind invisible mineral scale and soap residues. When the glass dries, these minerals bond with airborne dust, causing windows to look grimy again within days. We solve this by using specialized multi-stage water filtration. Our deionized pure-water systems absorb dirt on contact and dry naturally to a spotless, residue-free shine.
Since 2010, The Montreal Cleaners has delivered high-quality window care to homeowners, corporate offices, and property managers in Westmount, Laval, Longueuil, and surrounding communities. Every team member is an in-house employee—fully trained, background-checked, and covered by our comprehensive **$5,000,000 civil liability insurance**.

Meticulous Inclusions
Every Glass Pane Detailed, Corner-to-Corner
A premium service never stops at just the glass. Grime left on sills or inside track rails immediately washes back onto the window pane during the next rain. We detail every window systematically:
- Interior & Exterior Detailing: Manual squeegee squeak-free detailing on interior glass, and water-fed pure water pole sweeps on exteriors.
- Screen Washing & Rinsing: We remove window screens, scrub away pollen and dust, dry, and reinstall them.
- Track & Sill Vacuuming: Wet-vacuuming track channels to remove dead bugs, moss, and plaster dust, followed by frame wiping.
- Multi-Storey & Hard-to-Reach Glass: Extending safely up to 3 storeys using carbon-fiber poles, eliminating heavy ladder hazards on lawns.

Frequently asked questions
Window Cleaning FAQs
What is purified water window cleaning?
We run tap water through a multi-stage deionization filter to remove dissolved solids (calcium, magnesium). This purified water is fed through carbon-fiber poles to scrub the glass. When the window is rinsed, it dries naturally without leaving behind mineral spots or soapy residues.
Do you carry proper business insurance?
Yes. We carry a $5,000,000 general liability insurance policy to protect against accidental damage. All our staff are background-screened in-house employees covered under CNESST safety protocols. We can provide proof of insurance prior to starting work.
What is included in a standard window clean?
Our standard window service includes washing the glass surfaces (interior and/or exterior), brushing and wiping clean the window tracks, wiping down sills, and removing and washing the screens. We don’t consider a job complete if tracks are left grimy.
Do you clean windows in rainy weather?
We clean windows during light rain, as rain itself does not dirty windows (it’s the dust/minerals on the glass that rain smears). However, if there are heavy storms, high winds, or safety hazards, we will contact you to reschedule the appointment at no additional cost.
