At M&M Window Cleaners, we offer a wide variety of cleaning services. Whether you’re a homeowner, business owner, or property manager, our professional window cleaners can help your property look its best!

Window Cleaning for Homes in Markham

Your home’s windows do more than offer a view—they bring in light, improve air circulation, and add to your home’s value. But when dirt, pollen, and fingerprints build up, that light fades fast.

Our residential window cleaning service covers:
Interior and exterior window cleaning
Removal of cobwebs, dust, and water spots
Sill and screen wipe-downs
Skylights, sunrooms, and hard-to-reach windows
Safe ladder work for multi-level homes

Whether you’re in a new build near Cornell or a character home in Old Markham Village, we tailor our services to your property’s needs.

Tough Spots? We’ve Got It Covered

Hard-to-reach second-floor windows? Windows stained by sprinkler water or construction dust? Don’t worry—we’ve seen it all. Our team uses the right tools for the job, including extension poles, ladders, and eco-friendly solutions that cut through grime without damaging your glass or frames.

Our cleanings are always:

Safe for pets, kids, and gardens
Non-abrasive and residue-free
Performed with care and precision

Commercial Window Cleaning in Markham

Markham is a hub of growth, with thriving local businesses, modern offices, and busy storefronts. First impressions matter—and clean windows help set the tone. We work with businesses of all types to keep their glass clear and their image sharp.

We serve:

Office buildings
Retail shops and restaurants
Medical and dental clinics
Property managers and real estate offices

We offer flexible scheduling to work around your business hours, along with recurring service plans for consistent upkeep. Need a one-time clean before an inspection or event? We do that too.

Seasonal Cleaning Tailored for Markham

With four distinct seasons, Markham’s windows face a bit of everything: winter salt, spring pollen, summer dust, and autumn debris. Our seasonal window cleaning helps stay ahead of the mess and keeps your property looking sharp year-round.

Many clients book cleanings in:

Spring – Post-winter grime removal
Fall – Before the frost or for pre-holiday prep
Anytime – Before listing, events, or just because it’s time

Whether you need one visit or ongoing service, we’ll build a plan that works with your schedule.

We also offer seasonal packages and pre-listing cleans for homeowners putting their property on the market.
