Painting over contaminated exterior surfaces is one of the most expensive mistakes Ottawa homeowners make.

Paint applied over biological growth, mineral deposits, or salt-affected brick fails faster than paint applied to a clean substrate. The paint film bonds to the contamination layer, not to the brick. When the contamination shifts as biological growth continues its lifecycle and mineral deposits migrate the paint lifts with it.

A repaint on contaminated brick typically fails in 3–5 years. The same paint on a properly cleaned substrate: 8–12 years.

This Centretown East homeowner had received a painting quote for their painted brick exterior. Their painter recommended a professional soft wash first standard practice among Ottawa painters who understand substrate preparation.

We soft washed the brick. The biological growth, chalk, and pollution film came off. The existing paint, where it was properly bonded, was in excellent condition. Only one small section needed repainting a fraction of the full quote.

The painter came back, prepared the clean substrate correctly, and applied new paint only where needed.

Total project cost: significantly less than a full repaint over dirty brick that would have failed in four years.

The eavestrough industry in Ottawa has a quiet incentive problem.

Replacement is more profitable than repair. Repair is more profitable than "you're fine, see you in spring."

Clear Ottawa — Ottawa's Exterior Home Doctor operates on a different model.

We tell Ottawa homeowners exactly what their system needs nothing more. We've told homeowners their eavestroughs are in excellent condition and don't need servicing yet. We've recommended a single $75 joint repair over a $2,400 replacement.

The homeowner who trusts us because we didn't oversell them once is the homeowner who calls us every season for 10 years.

That's the only business model that makes sense to us.

The contractor told them the stucco had "failed" and needed full re-rendering.

It hadn't failed. It was covered in 6 years of biological growth, road particulate, and mineral staining accumulated on a finish that hadn't been professionally cleaned since the home was built.

Stucco is a porous rendered finish. It absorbs environmental contamination over time. The grey-green cast that develops isn't degradation of the render it's surface colonisation by algae, mold, and atmospheric particulate.

The correct treatment: soft washing at low pressure (never high-pressure stucco fractures along the aggregate surface under high PSI), with a biodegradable solution calibrated to the biological growth type and allowed appropriate dwell time before a gentle flush.

Two hours. The stucco is the same age it was before we started. It looks like the day it was applied.

The $18,000 re-render is still on the table if the homeowner wants it. But they don't. Not anymore.

People ask this and the honest answer is: it depends on what you're booking for.

Window cleaning: September is ideal. October is possible but condensation season makes results harder to maintain. November not worth it.

Eavestrough cleaning: October is still very much the season. This is what we're built for. Even with the calendar full, we make it work for people who've been waiting.

Eavestrough repair: October is the last window. Sealants need above 5°C to cure. Once Ottawa nights drop below that threshold consistently, repair work has to wait for spring and whatever damage it causes in the meantime happens on your watch.

The answer to 'is it too late' is almost never 'yes.' But the answer to 'is it easier and cheaper now than it was in August' is always 'no.'

Book now. We're still here.

When water enters a crack in concrete and freezes, it doesn't just sit there. It expands by approximately 9% of its volume creating internal pressure of up to 2,000 pounds per square inch inside the crack.

Ottawa's freeze-thaw cycle exposes concrete to this process repeatedly not just annually, but sometimes multiple times in a single week during shoulder seasons when temperatures cross zero degrees repeatedly.

Over three to five cycles, a hairline crack becomes a surface fracture. Over ten, the concrete surface begins to spall the top layer separating from the substrate.

The preventive measure is simple: remove biological growth and surface contamination before winter, and apply a penetrating concrete sealer that reduces water infiltration into the surface pore structure.

A sealed surface doesn't eliminate freeze-thaw stress. It significantly reduces how much water enters the crack system to begin with.

Anthocyanins, the pigments that turn Ottawa's maples red are produced as the tree withdraws nutrients from leaves before dropping them.

By the time a leaf is fully red, the tree has pulled almost all its chlorophyll, nitrogen, and phosphorus back into the branch. What falls into your eavestrough is a desiccated, lightweight, tightly packing organic material.

Red leaves compact faster and more densely than green ones. A channel that handles green leaf load in September can become fully restricted under the same volume of red leaves in October.

Gatineau Park hits peak colour this week. The leaves that look most beautiful from the parkway are the ones that pack most tightly into the trough channel when they drop.

One clean before the peak. Then one after. That's the fall eavestrough protocol.

A standard eavestrough inspection assesses what is visible: the trough channel, the joint connections, the hanger hardware, the debris load.

What is not visible from standard inspection: the inside of the downspout column.

Downspout columns are typically 3–4 inches square and run 2–3 metres from the trough connection to the exit point. Blockages within the column compacted debris, wasp nest material, or in Ottawa's older homes, collapsed internal corrosion cannot be identified without either flushing the column and observing the exit or using a flexible camera system.

The compact waterproof cameras now used in professional eavestrough inspection can navigate a 3-inch downspout column and image the full interior. Common Ottawa downspout findings:

→ Collapsed section in older galvanised steel downspouts where internal corrosion has buckled the material
→ Wasp nest material that has hardened over multiple seasons into a solid internal plug
→ Debris compaction at a reduction in the downspout internal dimension (typically where sections join)

A downspout that appears to drain correctly from outside can have an internal restriction at 60–70% that standard cleaning misses.

This is not standard across every Ottawa cleaning company. It is standard at Clear Ottawa — Ottawa's Exterior Home Doctor.
