In April 2025, our crews pulled 1,247 kilograms of debris out of Toronto gutters in a single week. Not leaves — that was the October job. This was compressed sludge, roof-shingle grit, and the tennis ball from a summer two years ago. Every one of those homes looked fine from the curb. That is the Toronto spring exterior cleaning problem in one sentence: most of the damage winter did to your home is hidden, and it gets more expensive every week you leave it alone.
This checklist is what our estimators actually walk through on GTA properties between late April and mid-May. It's ordered by urgency, not by effort — because the cheapest jobs aren't necessarily the ones that should wait. By the end you'll know exactly what you can handle this weekend, what to hand off, and what you're allowed to ignore for a year.
The Toronto spring exterior cleaning checklist, in order: gutters → windows → north-wall soft wash → driveway → interlock re-sanding → deck/fence → soffits → solar panels → foundation drainage → salt stains → curb appeal items → summer-service bookings. Do the top five before the first heavy May rain. The rest can stage through late May and June.
Why Toronto spring is different
Toronto springs are short, wet, and ragged. Nighttime lows hover around freezing into mid-April, then one week flips to 20°C and every homeowner in Leaside, Forest Hill, and Mississauga starts calling crews at once. Three things stack on top of that:
- Road salt. Toronto uses around 130,000–160,000 tonnes of salt each winter. Wind and spray carry it onto windows, siding, and masonry — not just on cars.
- Ravine and mature-tree canopy. Forest Hill, Rosedale, Bayview, Leaside, and North York have thousands of homes under mature maple and oak canopy. Gutters fill two or three times faster than an open suburban lot.
- Freeze-thaw. The GTA averages 40–60 freeze-thaw cycles per winter. Every one of those cycles works on mortar, caulk, and sealed paver joints. Spring is when you see the damage.
None of this is new to us — we run ten different exterior services on Toronto properties year-round, and this is the busiest eight weeks of the year. The good news: most of what looks like damage after a Toronto winter is surface-level if you catch it in the first 60 days of warm weather.
The 12-item answer
Every item below has three tags: DIY, Pro, or Mixed. Items are ordered by cost-of-neglect — if you only do the first five, you'll prevent 80% of what we're called for in June as emergency work.
1. Gutters & downspouts — Pro
First job, every year. Winter leaves a dense crust in Toronto gutters: late-fall leaves compacted by snow, shingle grit washed off the roof, and ice-dam residue. A visual check from the ground is useless — compression hides debris below the lip of the gutter.
A proper inspection means a physical walk of the gutter run, full debris removal, a downspout flush (we use water pressure, not just compressed air), and a report on sagging hangers, open joints, and missing end caps. Our gutter cleaning service includes that inspection report as the default, because the real value of spring gutter work isn't the cleaning — it's finding the $150 repair before it becomes a $15,000 basement.
Why it's first:blocked gutters in May cause fascia rot, soffit damage, and foundation pooling during the heavy spring rains that follow Toronto's first warm week. Skip nothing else on this list before you skip this.
2. Windows (inside and out) — Mixed
Interior: DIY is fine. Get a microfiber cloth and a streak-free solution, work top-down, and you'll match most professional results on ground-floor panes.
Exterior: hand it off. Not because the work is hard, but because the height, the salt film, and the hard-water mineralization need the right chemistry. Toronto tap water leaves spots on its own; layered on top of winter salt residue, it etches glass slowly over the summer. A pro exterior window clean removes both in one pass. Our base window cleaning starts at $150 and scales with pane count and height.
3. Soft wash the north-facing walls — Pro
Toronto homes with a north-facing brick or stucco wall develop green algae and black mildew growth by late May — faster on ravine lots and shaded elevations. It's not cosmetic. Left alone, it holds moisture against the wall and accelerates mortar erosion on older brick.
Crucially, do not pressure-wash heritage brick. Anything older than about 1965 in Toronto is bedded in lime mortar, which modern pressure washers erode permanently — often on the first pass. Use soft washing instead: low pressure, plant-safe chemistry, 30-minute dwell time, gentle rinse. It kills the biology at the root so regrowth takes two to three years instead of two to three months.

Concrete driveways in the GTA collect a brutal winter cocktail: salt, de-icer, oil drips from the car, mud from the boulevard. A spring pressure washlifts all of it in one pass. Once it's restored, a DIY rinse every few weeks keeps it presentable for the rest of the year.
Watch the PSI. Old concrete, stamped concrete, and exposed-aggregate driveways all tolerate different pressure ranges. Pros tune the nozzle by surface; most consumer-grade pressure washers run at a single setting and can blow out aggregate or leave visible wand stripes. We set pressure by surface, not by habit.
5. Interlock: re-sand, don't just wash — Pro
This is the one most Toronto homeowners get wrong. A pressure wash on interlock feels productive — it blasts out the dirty sand, the weeds, and a decade of organic debris. But if you stop there, you've just removed the structural binder between your pavers. Weeds grow back faster, pavers shift, and ant colonies move in within a season.
The correct sequence: pressure wash at joint-safe PSI → dry 24 hours → sweep in polymeric sand → mist with water to activate → cure for 24 hours. Total protection: three to five years. Our polymeric service runs $2–$9 per square foot depending on joint width and paver type.
6. Decks & fences — Mixed
Sweep, inspect for rot or loose boards, then decide: clean-only or clean-and-seal. A spring power washremoves winter grime and any mildew buildup. If you're planning to re-stain, the deck must be fully dry and clean before staining — that's what makes the stain last three years instead of one. Skip the chemistry pressure wash and you'll be refinishing next spring.
7. Soffits & porch ceilings — Pro
Century homes in Leaside, The Kingsway, and Bayview have painted porch ceilings and decorative soffits that accumulate cobwebs, wasp nests, and carpenter-bee entry points over winter. A ceiling and soffit cleaning starts at $199 and is the detail piece most homeowners skip — then regret in photos.
8. Solar panels — Pro
If you installed solar in the last five years, spring cleaning isn't optional — it's your single highest-ROI maintenance item. Our solar panel cleaning uses deionized water and a soft brush, and we routinely measure 15–25% output increaseson panels that haven't been cleaned since install. Pollen-coated spring panels are worse than winter snow, because the snow slides off and the pollen doesn't.
9. Foundation grading + downspout extensions — DIY check, pro repair
After your next rainfall, put on boots and walk the perimeter of the house. You're looking for two things: water pooling within six feet of the foundation, and downspout outlets that dump straight down instead of flowing away. Either one means water is being delivered to your basement.
The fix is extensions — four to six additional feet of downspout pipe that redirect water past the foundation. Cheap to install, almost impossible to regret. This is the item homeowners forget most often.
10. Salt stain assessment — Pro for anything not glass
Salt etches brick, stucco, limestone, and porch wood if left through spring humidity. If you can see white residue on lower walls, around the front door, or on the garage surround, it's time for a neutralizing rinse. On glass, salt film is cosmetic. On brick and limestone, it's chemistry working against you.
11. Pre-listing curb appeal — Pro
If you're listing this spring, bundle everything above into a single crew visit two to three days before listing photos. Clean windows, streak-free glass, and a freshly-washed driveway are the three things buyers notice in the first four seconds of a showing. Toronto realtors we work with on Forest Hill and Rosedale listings routinely credit exterior prep with moving offer dates earlier and driving competing offers.
12. Book summer services now — free
Peak scheduling is May 15 to June 30. If you want a specific Saturday for holiday deck prep, a pre-wedding venue clean, or a mid-summer condo facade job, book the slot in April. Crews in Rosedale, Yorkville, and Oakville are already 70% committed by the last week of April in a normal year.
DIY vs. pro: the honest cut
We'll say this directly: not every item on this list needs a paid crew. If you're physically able, enjoy the work, and own a ground-floor home with straightforward access, here's what you can legitimately handle yourself:
- Interior windows (all floors, inside)
- Basic deck and patio sweeping
- Foundation perimeter walk-through
- Minor concrete driveway rinses (maintenance between pro washes)
- Garden-bed edging and debris cleanup
Here's where DIY becomes false economy:
- Gutter cleaning. Every year in Toronto, people fall off ladders doing gutter work. The average ER visit costs more than twenty years of professional service.
- Heritage brick soft washing. The wrong chemistry or pressure on lime mortar is permanent damage. Repointing a Rosedale wall starts at $15,000.
- High-rise or 3+ storey windows. Beyond insurance and safety, you need rope access or boom-lift certification to do it legally in Ontario.
- Polymeric sanding. DIY poly sand application failures are the most common call we get in July.
- Solar panel cleaning. Hard water damages cells; deionized water is specialty equipment.
Bundle or handle it in stages?
If you're doing four or more items from this list, bundling saves money — typically 15–20% off the a-la-carte rate — because we're already on-site with the full kit. A typical Toronto spring bundle looks like this:
| Property | Typical spring bundle | Range |
|---|---|---|
| Detached, standard lot | Gutters + ext. windows + driveway wash | $550–$900 |
| Ravine-lot or mature-tree | Above + soft wash one elevation | $850–$1,400 |
| Heritage or estate | Full perimeter soft wash + gutters + windows + interlock | $1,800–$4,500 |
| Condo (high-rise unit) | Ext. window cleaning (certified crew) | $250–$600 |
Staging is fine if cash flow matters more than convenience. The only rule: do gutters and foundation drainage first, in that order. Everything else can wait.
“I've had the same crew come every spring for four years. They catch things my roofer doesn't — a missing downspout strap last spring, a cracked gutter miter the year before. It's cheaper than one emergency repair.”— Sarah M., Leaside homeowner · Ravine-lot gutter & window service, 2025
That's the pitch for spring exterior cleaning in one paragraph. Not that your house is dirty. Not that it needs to look better. But that a 90-minute walkthrough in April will surface the three or four small items that would otherwise become a big item in July. Our crew carries $2M in liability insurance, is fully bonded, and backs every job with the 6ix Shine satisfaction guarantee — if you aren't happy, we come back.
