A Toronto homeowner's guide to getting your windows right after winter. Timing, pricing, and the spring bundle that saves you money.
If you've made it through another Toronto winter, your windows know it. Between the road salt spray, ice melt chemicals dripping down the glass, construction dust from every condo going up on the Danforth, and the freeze-thaw cycles that grind grime into every corner of your frames, your windows have taken a beating since November.
Spring window cleaning isn't just about aesthetics. It's about protecting your glass, letting natural light back in, and setting your home up for the warmer months. This guide covers everything Toronto and GTA homeowners need to know: when to book, what it costs, whether DIY is worth it, and how to bundle services for the best deal.
Toronto winters are uniquely harsh on windows. Here's what five months of cold weather actually does to your glass:
The bottom line: the longer winter grime sits on your windows, the harder and more expensive it is to remove. A spring cleaning in early April costs less than a restoration job in July.

The freeze-thaw cycle usually ends in Toronto around the third week of March. Once overnight temperatures stay above -2°C consistently, it's safe to clean. If you're in Scarborough or along the lake, wait until the last week of March to be safe.
This is the sweet spot. Winter grime has loosened from warmer rain. Pollen season hasn't peaked yet (birch and oak pollen hits hard in late April and May). Your windows get the longest stretch of looking great before summer. Most professional companies, including MANTLE, start filling up fast in the first week of April.
Still a great time to clean, but be aware that pollen will start coating everything by late April. If you have mature trees on your lot, especially birch, maple, or oak, your windows will collect a yellow-green film within a couple weeks of cleaning. Not the end of the world, but early April gives you a longer clean window (no pun intended).
A proper spring window cleaning is more thorough than a routine summer touchup. Here's what a good company should include:
At MANTLE, we use ClearCoat purified water technology on every job. We filter the water down to zero parts per million of minerals before it touches your glass. This means zero streaks, zero water spots, and your windows stay cleaner 2 to 3 times longer than tap water methods. It's not a gimmick. It's the same system used on high-end commercial buildings.
We're not going to tell you that DIY is terrible and you must hire a pro. Here's an honest breakdown so you can decide what makes sense for your situation.
When DIY makes sense: You have a single-storey home, fewer than 10 windows, and you own a good squeegee. You're comfortable on a step stool and have a free Saturday morning.
When hiring a pro makes sense: You have a two-storey or taller home. You have more than 12 windows. You want the job done in under two hours with no streaks. You don't want to haul a ladder around your house. Or, frankly, you'd rather spend your Saturday doing literally anything else.
One thing worth noting: if you use tap water (which is hard in most of the GTA, around 120 to 140 ppm), you'll get mineral spots as the water dries. Purified water systems like our ClearCoat technology eliminate this completely. That's the single biggest quality difference between DIY and professional results.
A little prep goes a long way. Do these before your crew arrives and the job goes faster (which keeps the cost down):
Windows are just one part of the spring exterior cleanup. After a Toronto winter, here's the full checklist for getting your home's exterior back in shape:
The smartest move is to bundle as many of these as possible into one visit. That's why we created our spring bundle.
This is the most popular service we offer in April and May, and for good reason. After a Toronto winter, your gutters are packed with leaves, shingle grit, ice dam debris, and whatever else blew in over five months. Your windows are coated in salt and grime. Doing both at once saves you money and gets everything handled in a single visit.

Period. We've never had to refund a job, but the guarantee exists because we stand behind our work completely.
Late March through mid-April is ideal. The freeze-thaw cycle typically ends in the third week of March, and pollen season picks up in late April. Early April hits the sweet spot where winter grime has loosened but pollen hasn't arrived yet. Book 1 to 2 weeks ahead since spring is the busiest season for window cleaning across the GTA.
For 2026, expect $149 to $599+ depending on your home size. Small bungalows start at $149 for exterior only. A typical 2-storey home costs $249 to $349 for exterior, or $399 to $499 for interior and exterior. The spring bundle (windows + gutters) saves $50 on the combined price.
Toronto winters deposit road salt, ice melt chemicals, construction dust, and mineral-laden lake moisture on your glass. These substances are corrosive. Salt and calcium chloride can etch glass surfaces permanently if left for months. Spring cleaning removes these contaminants before they cause lasting damage, and it lets significantly more natural light into your home.
Ground-floor windows on a single-storey home are a reasonable DIY project if you have a squeegee and cleaning solution. For two-storey homes, hiring a professional is safer and produces better results. The biggest quality difference is water: pros use purified water (zero minerals) that dries streak-free, while GTA tap water leaves mineral spots. A professional crew also finishes in 1 to 2 hours versus a full Saturday of DIY work.
The spring bundle combines window cleaning and gutter cleaning in a single visit. You save $50 compared to booking them separately, and everything gets done in one appointment. After a Toronto winter, your gutters are almost certainly full of debris, so handling both at once makes practical and financial sense.
