One-off exterior clean or a seasonal booking: how to decide

The choice between a one-off exterior clean and a recurring booking is usually settled by something you can check in ten minutes: whether the material that dirties your property arrives in a single event or keeps arriving for weeks. Leaves, sprinkler spray and grass growth give different answers to that question, and they give different answers from one Oakville street to the next. This is how to run the test on your own address, what each answer means for gutters, windows and the lawn, and what an Ontario services agreement has to contain before you commit to a season of anything.

Does the mess arrive once, or over six weeks?

For leaves in this area the answer is six weeks, and the towns publish the proof in their own operating schedules. Oakville's 2026 loose leaf collection programme runs October 26 to December 4 and alternates zones week by week: zones 1, 2, 3 and 7 are collected in weeks one, three and five, zones 4, 5, 6 and 8 in weeks two, four and six. Every zone gets three passes. Three passes per zone is the town's own working estimate of how long the leaves keep coming.

Mississauga states the same thing from the other direction. Its fall leaf pickup page has a section headed for residents who "missed the City's leaf pickup or more leaves fall after your scheduled leaf pickup", and sends them to Peel yard waste bins or paper bags for the remainder. The city is not treating one scheduled visit as the end of leaf fall.

Apply that to a gutter. A trough emptied in the third week of October, on a lot with mature trees over the roofline, is refilling while the town is still on its second pass. Oakville is blunt about the equivalent situation on the road: "Once the street has been collected, we will not return until the next scheduled pick-up." A single autumn visit on a heavily treed lot is not wrong — it is one visit at a moment you have chosen, and everything that falls afterwards stays there until spring.

The ten-minute test for your own address

Two questions decide almost all of it: how much mature canopy stands over your roof, and whether anything sprays your glass. Both have free public answers, and neither requires a quote.

1. 1Check whether your street is on the leaf routeOakville provides loose leaf pickup in neighbourhoods that are at least 25 years old and have many large mature trees, and says plainly that there are areas where the programme is not offered "since the number of mature trees does not warrant the bulk leaf pickup service". Mississauga's threshold is streets "more than 35 years old" with many large mature trees. If your street is on the route, the town has already judged its tree load heavy enough to need a machine three times an autumn, which is the strongest free signal you will get about your own roofline.
2. 2Stand at each downspout and look upCount the branches that cross the roofline above that corner of the house. A downspout under open sky and a downspout under three overhanging limbs are not on the same schedule, even on the same house. Note which elevations have branches over them, because that is what a quote for "the gutters" should be broken down by.
3. 3Run the irrigation and watch where the water landsIf any head throws onto glass, brick or aluminum, the spotting comes back on the watering schedule rather than the calendar, and washing more often does not stop it. Aiming the head down is the fix; the mechanism is set out in why sprinkler water leaves spots on glass.
4. 4Confirm which parts of the exterior are actually yoursIn a condominium, corporations are responsible for repairing common elements and standard unit elements, while owners are responsible for decorative and non-standard unit elements — and a corporation can amend those obligations in its own governing documents. The Condominium Authority of Ontario's advice is to check the governing documents and the Condo Act to determine exact responsibilities. Do that before paying for recurring work on anything outside your own boundary.
5. 5Write down when each job was last doneIf you cannot remember, that is the answer for this year. Book the single visit now, look at the result, and decide about a recurring schedule after you have watched one full cycle on your own property. Nobody can tell you your cycle from a phone call.

What actually recurs, and what is genuinely once a year

Grouping exterior work into "cleaning" hides the fact that these jobs are driven by three different clocks. Some follow an event, some follow growth, and some follow the calendar and happen once.

Watering is worth singling out. Health Canada's lawn guidance is to water deeply and infrequently — at least 2.5 cm at a time, no more than once a week without rain, in the morning — and to leave the clippings where they fall. None of that needs a contractor, and a lawn that goes dormant in a dry August is not a lawn in trouble: "A healthy lawn can survive several weeks in a dormant state." Aeration deserves one caution before anyone quotes it as an annual line item: Health Canada's signs that a lawn needs it are hard, compacted ground, thatch building up, water that does not penetrate, and weeds like knotweed and clover — and it notes that aerating "does not, however, apply to soil types containing clay".

What a seasonal agreement has to say before you sign it

Under Ontario's Consumer Protection Act, most agreements for a product or service costing more than $50 must be in writing, and the province names hiring "a general contractor or mover or snow removal services" as an example. The written contract has to show all the terms and every fee. Five things are worth reading for before you sign a season of anything.

• The visit count the price assumes, and what triggers a visit. A seasonal price is an average of a number the company has in mind. Ask what that number is and write it down.
• A written estimate that is part of the contract. Where a written estimate is included in the contract, the final price "cannot be more than 10% above the estimate, unless you agree to a new price and sign a change to the contract". An estimate emailed separately and never attached does not carry that protection.
• How it renews. A business must give you written notice of any change, renewal or extension, listing the proposed changes, the date they take effect, how you must respond, and what happens if you do not respond. Automatic rollover without that notice is not permitted.
• How you get out. If you sign in your home you always have a cooling-off period — 10 days from the day you receive a written copy, for any reason. For most contracts the company then has 15 days to return your money.
• Any clause forcing private arbitration. Ontario's position is that you are not bound by those clauses even if you accepted the agreement, and you keep the right to complain to the ministry or take legal action.

One point of accuracy, because it gets repeated wrongly: Ontario restricts door-to-door selling only for a specific list — furnaces, air conditioners, air cleaners and purifiers, water heaters, water treatment and filtration devices, and duct cleaning services. Lawn, gutter and window work is not on that list and can still be sold at the door. Everything above still applies to it, including the 10-day cooling-off period.

When the one-off is the right answer

Four situations where paying for a season is paying for visits you will not use.

• No mature canopy over the roofline, and your street is not on the leaf route. One clearing after the last leaves are down covers the year. Check the result yourself afterwards using the signs visible from the ground.
• You are selling or moving within about two months. Buy the single clean the listing or the lease actually needs — what gets checked at a move-out is a different job from ongoing upkeep.
• You already do the mowing. Health Canada's guidance is a cutting height of 6 to 8 cm and clippings left on the lawn. If you are doing that, a one-time cut for the weeks you are away is the whole requirement, and one-time cuts are booked the same way as a schedule.
• You have never had the work done here. You do not yet know your own cycle. One visit, then a decision, costs less than a season chosen blind.

Comparing two quotes that are not the same shape

A per-visit price and a seasonal price cannot be compared as written. Convert both to a cost per visit, then find out what moves the visit count.

1. Ask each company how many visits its seasonal price assumes for a property like yours, and divide the price by that number.
2. Ask what triggers a visit under the recurring option — a date, a call from you, or a condition somebody has to assess.
3. Ask what happens in a heavy year. If leaf fall runs long, does the season cover the extra visit or is it billed?
4. Ask what happens if you need fewer. A seasonal price that never adjusts downward is a fixed price, and should be compared as one.
5. Check whether the once-a-year items — aeration, overseeding, a spring cleanup — are inside the seasonal figure or quoted separately. This is where two seasonal prices most often differ.

Every Season lists weekly, bi-weekly and one-time lawn cutting with no long-term contract, and its landscaping page offers both recurring maintenance and one-time projects such as seasonal cleanups and sod installation. The gutter page lists optional seasonal plans alongside single jobs, and window cleaning covers exterior, interior, screens and tracks whether you book it once or repeatedly. That flexibility only helps once you have decided which shape your own property needs, which is what the ten-minute test above is for. If you want the whole year laid out first, the month-by-month property calendar shows where each job lands.
