By late April, most Canadians have made peace with the long winter and are quietly chasing the same thing: more daylight. Front porches start to fill up again. Curtains stay open longer. There is a noticeable shift in mood the moment afternoon sun reaches into a kitchen at four o’clock instead of three. It happens every year, and every year homeowners seem a little more aware of how much that shift matters.
What used to be called spring cleaning has started to look different in Canadian homes. It is less about top-to-bottom scrubbing and more about a deliberate reset of the spaces that carried us through the dark months. Walk through Centretown, the Glebe, or Westboro right now and the message is the same. Open the windows. Let the light back in. Pay attention to what has been quietly building up since November.
The numbers behind Canadian indoor life are worth pausing on. Health Canada and various public-health studies estimate that Canadians spend roughly 90 per cent of their time indoors, a figure that climbs even higher in the winter months. Combined with shorter daylight hours, that leaves many adults averaging a fraction of the sun exposure recommended for healthy vitamin D production. The Canadian Cancer Society and several university research groups have noted for years that vitamin D deficiency is common across the country, especially north of the 42nd parallel, which covers most of southern Ontario.
It is not only a physical issue. Seasonal Affective Disorder affects an estimated two to six per cent of Canadians in any given winter, and a much larger share notices a milder, low-grade version. By the time spring properly arrives, the cumulative effect of months of low light is something most households feel even if they do not name it. The return of natural light does real work on mood, energy, and sleep quality, and a growing body of research supports what most of us already sense.
The benefits of brighter interior spaces are surprisingly well documented. Morning exposure to natural light helps regulate the body’s sleep-wake cycle. Office and classroom studies have shown measurable improvements in alertness and concentration in well-lit rooms compared with rooms relying on fluorescent overheads. Houseplants need significantly more light than their owners assume, and real-estate stagers will tell you that nothing makes a room read larger and cleaner than full natural light through a clean window. The easiest way to lose a sizable share of incoming daylight, then, is to leave the surface that lets it in dirty.
A pane of glass that has not been properly cleaned in six to twelve months can lose somewhere between 15 and 30 per cent of its visible light transmission, depending on the household, the air quality of the neighbourhood, and how many trees and pollen sources are nearby. Inner-city windows in Centretown or Hintonburg tend to accumulate a film of urban grime that is almost invisible until the day after a thorough clean, when the colour of the light coming in suddenly looks different. Heritage homes around the Glebe present a different challenge, with original wood sashes and arched detail windows that ask for slower, more careful work.
For most homeowners, the spring window reset is a two-part job. The interior is straightforward with a microfibre cloth, a vinegar-based cleaner, and a squeegee. The exterior is where the work gets serious, especially on two-storey homes, properties with original heritage sashes, or houses with pollen-heavy trees nearby. That is the point at which a lot of households quietly stop doing it themselves. Companies that handle residential exterior cleaning across Ontario, including DT Cleaning, report a clear seasonal demand spike in April and May. Their clients are not just luxury homeowners. They are families with two working parents, retirees who would rather not climb a ladder, and condo owners who want their balcony glass done properly before patio season.
The most efficient way to approach the seasonal reset is to treat the exterior of the house as one project and the interior as another, then book or schedule both within the same two-week window. Eavestroughs are usually first, because winter wind and late-fall leaves leave gutters partially blocked, and water moving freely through the system protects the foundation when spring rain arrives. Exterior windows come next, ideally before pollen season peaks in late May. Doing them earlier extends the visibly clean period by weeks.
Window screens are the step most people skip, and they make a surprising difference in airflow once windows start staying open. Removing them, washing them flat, drying them, and reinstalling is twenty minutes of work that pays itself back through the first warm weekends. The HVAC filter deserves the same attention. Six months of dry indoor air leaves more dust behind than most homeowners assume, and the difference in the first few days after a change is noticeable.
A small audit of the house at three different times of day is worth more than it sounds. Walk through and note which rooms feel dim and why. Sometimes the answer is a heavy curtain. Sometimes it is a window that has been quietly losing its view. Once that pass is done, a power wash of the patio, the stone walkway, and any garden furniture brings the outdoor living space back online in time for the first warm weekend.
Statistics Canada data on time use shows that the average Canadian household spent fewer hours on home maintenance in 2024 than they did a decade earlier, even as homes themselves became larger and more complex. The math is not mysterious. Two-income households with children rarely have a free Saturday in May, and the appeal of buying back a weekend is real. Add to that the safety question that comes with climbing a ladder to clean a third-storey window, and the case for outsourcing parts of the spring refresh writes itself.
DIY still makes sense for single-storey homes with easy ground-floor access, dry weather, no ivy or wildlife issues on the exterior, and a homeowner who actually enjoys the work. In those cases, a quiet Saturday with a hose, a microfibre cloth, and a squeegee can be its own small reward. The job is worth handing off when the property is multi-storey, when roof access is involved, when sunrooms are pollen-coated, when eavestroughs have damage, when mosquito screens need detailed work, or when the homeowner would rather not spend a morning on a ladder. The cost of a single professional service call is almost always lower than the cost of one bad fall.
The questions that come up around this time of year are remarkably consistent. Twice a year is the working answer for most exterior window cleaning in Ontario, once in spring after the worst of the pollen has settled and once in fall after leaf drop. Homes near busy roads, construction sites, or large trees often benefit from a third clean mid-summer. For interior glass, the brand of cleaner matters less than people think. A vinegar mix produces very similar results to a commercial spray, and streaks almost always come from the cloth, not the spray itself.
The price of a professional service in most Canadian cities runs between $230 and $400 for a standard interior and exterior job on a two-storey family home. Heritage homes, condos with hard-to-reach glass, and larger properties run higher. The cost has stayed fairly steady over the past few years, even as labour rates have moved. The best month for a full spring exterior refresh in southern Ontario is late April through the second week of May. By that point, the snow has fully retreated, overnight temperatures are reliably above freezing, and trees have not yet released the heaviest pollen of the year.
It is easy to dismiss the seasonal reset as a chore, but the homeowners who get the most out of it tend to frame it differently. They are not cleaning a house. They are giving the space they live in a chance to do its job for the next six months. The light that comes through a freshly cleaned window in May has a quality to it that no replacement bulb can match, and the small effort it takes to let it back in pays itself back almost daily until October.
The arrival of spring in Canada has always carried a certain ceremony with it. The new version of that ceremony has less to do with how much we scrub and more to do with how deliberate we are about what we are bringing back into the home. More daylight, fewer obstacles, and a few more weekends spent enjoying the result.
