Ottawa gets 4 hours of sunshine per day in October.

Seasonal Affective Disorder affects up to 15% of Canadians.

The connection between dirty windows and winter mental health is real, documented, and almost never talked about.

This reel covers the research and the one change that costs almost nothing.

A ladder, a garden hose, and a willingness to climb will clear visible debris from the top of an eavestrough channel.

What DIY cleaning does not typically address:

Downspout entry blockage. The single most common blockage point in Ottawa eavestroughs is where the trough meets the downspout entry packed with shingle grit and fine debris. This is almost never visible from a ladder position.

Joint inspection. Detecting a failing joint requires applying pressure and observing the response not possible while managing a ladder on the exterior of a house.

Hanger integrity check. Each fastener should be physically tested for movement. This requires two-handed attention at height not safely achievable during self-service cleaning.

Downspout flush and exit confirmation. The downspout channel should be water-flushed and the exit point confirmed to be discharging correctly. This requires a helper at ground level while flushing from above.

Written documentation. Condition notes, photographs of any damage, and a maintenance timeline recommendation cannot be produced while managing the physical clean.

DIY cleaning maintains a system that is already functioning. Professional inspection discovers what isn't.

Ottawa's first frost arrives around October 19 on average.

What happens inside a debris-filled eavestrough when that temperature hits is something most homeowners have never thought about and it explains why October damage is always more expensive than September prevention.

This reel shows the exact mechanism. No sales pitch. Just physics.

Condensation between the panes of a double-glazed window is a specific, diagnosable condition called insulating glass unit (IGU) seal failure.

Here's the mechanism:

Modern double-pane windows are sealed units. Between the panes sits an inert gas usually argon which provides thermal insulation. Around the perimeter of the unit is a desiccant-filled spacer bar that absorbs trace moisture.

When the perimeter seal fails from age, Ottawa's temperature cycling, improper installation, or UV degradation argon escapes and humid air enters. The desiccant becomes saturated. When temperature differences cause the entered humidity to condense, it does so between the panes where it cannot be wiped away.

The fogging appears and partially clears based on temperature, but the condensation pattern never fully resolves. That's the diagnostic marker: interior condensation clears with ventilation. Between-pane fog does not.

Quality double-pane seals last 15–25 years.

An Ottawa home built in the late 1990s or early 2000s with original windows is approaching or past this window.

The fix is not cleaning. It's IGU replacement the glass unit is replaced while the frame is retained, in most cases.

Silicone and polyurethane sealants, the materials used for eavestrough joint repairs are temperature sensitive during cure.

Most exterior-grade eavestrough sealants specify a minimum application temperature of 5°C and require temperatures to remain above 5°C for 24–48 hours post-application to achieve full cure.

Ottawa's average overnight low in October drops below 5°C on approximately October 15–20. By late October, overnight lows regularly reach 0–2°C.

What this means practically:

A sealant applied to a joint at noon in late October may reach the minimum cure threshold but if temperatures drop overnight before the cure is complete, the sealant partially cures in a stressed state. The result is a repair that appears complete but fails at the first freeze-thaw cycle typically within weeks.

Repairs done in August cure fully in warm conditions and bond properly to the eavestrough material. The same repair done in late October has a significantly shorter expected lifespan.

This is not a reason to avoid autumn repairs entirely it's a reason to understand that timing within the season affects material performance.

In descending order of "we did not expect this"

#5 A full bird nest.
Starlings and sparrows find eavestrough corners ideal nesting locations. A mature nest redirects all overflow to the corner joint. Found in approximately 1-in-4 Ottawa homes we service.

#4 A wasp colony.
Peak discovery: August. Peak size: thousands of workers. The nest blocks the corner junction entirely and adds structural pressure to the joint from inside. Do not attempt to clear this yourself.

#3 A maple seedling.
Ottawa's silver maples are extraordinarily good at germinating in organic debris and standing water. We have found seedlings up to 20cm tall inside eavestrough channels. The roots work into joint sealant.

#2 A tennis ball.
No further explanation available.

#1 A fully composted layer.
Debris that has been in the trough long enough to fully decompose into soil. Dark, nutrient-rich, and capable of supporting plant life. Requires hand removal it no longer flushes.

Gutter guards reduce debris entry. They do not eliminate it.

The specific failure mechanism most Ottawa homeowners with guards don't know about: fine debris accumulation on the guard surface.

Micro-mesh guards work by allowing water to pass through while debris remains on top. In theory, rain washes that surface debris off the guard. In practice, in Ottawa's humid autumn conditions, fine debris shingle grit, pollen fragments, pine needles forms a damp mat on the mesh surface.

That mat doesn't wash off. It sits on top of the mesh and gradually reduces water infiltration through the guard redirecting water over the front edge of the eavestrough rather than through the system.

The result: a guard-protected eavestrough that overflows not because of debris inside the trough, but because of debris on top of the guard.

Solution: an annual inspection and surface clearing of the guard system typically faster and less intensive than a full clean, but necessary.

Over 70% of double-pane windows experience some form of moisture infiltration within 15 years of installation. The parallel is exact: the maintenance solution doesn't eliminate the problem, it manages it.

Window contamination is angle-dependent.

A window examined in diffuse morning light from inside the room may appear clean. The film on the glass doesn't show in flat, even lighting.

The same window photographed in raking afternoon light. Sunlight arriving at a low angle across the surface reveals the mineral deposits, pollen residue, and surface haze that were invisible at 9 AM.

This is why homeowners often believe their windows are clean when they're not. The assessment is being made in conditions that don't reveal the contamination.

Photographers know this. They call it "raking light" used deliberately to reveal surface texture. Forensic investigators use it to find latent fingerprints. Glass professionals use it to assess window cleanliness properly.

The correct way to assess your window: stand inside on a sunny afternoon. Look toward the light source. What you see then is what the glass is actually transmitting.

If it looks hazy it's blocking more light than you realise.

Autumn colour change is not the tree dying it's the tree protecting itself.

As daylight shortens in October, trees stop producing chlorophyll (the green pigment). As chlorophyll breaks down, it reveals the yellow and orange carotenoids that were always present but masked.

The red colour anthocyanins is actually produced fresh in autumn. Scientists believe it serves as sunscreen, protecting the leaf during nutrient withdrawal. Trees with more sugar in their leaves produce more vivid reds.

Ottawa's red maples produce some of the most anthocyanin-rich leaves in the country which is why the Gatineau Hills colour display is exceptional.

The maintenance connection: by the time a leaf is fully red, the tree has completed its nutrient withdrawal. The leaf is desiccated, lightweight, and structurally weakened. Red leaves compact inside eavestrough channels more densely than green ones the desiccated structure collapses under water weight into a tighter, less permeable mat.

Beautiful to look at. Efficient at blocking gutters.
