Aluminum Siding, Capping and Eavestrough in Etobicoke: Lakeshore Homes to Post-War Bungalows

• Mimico, New Toronto and Long Branch were separate lakeshore municipalities until they joined the Borough of Etobicoke in 1967.
• Etobicoke’s population grew from under 40,000 to over 200,000 in the two decades after the Second World War.
• Toronto Pearson, on Etobicoke’s northwest edge, averages about 115 cm of snow and 807 mm of total precipitation a year (1991–2020 normals).
• Typical aluminum siding runs $9–$16 per sq ft installed; window capping $175–$450 per window (2026 GTA ballpark).
• Every Pro Aluminum Siding job is quoted free and covered by a written contract and a 5-year workmanship warranty.

One district, three kinds of house

Etobicoke is really three housing landscapes stitched together, and each one wears out its exterior in a different way. Knowing which one your home belongs to is the fastest way to decide what to fix first.

The lakeshore villages

Mimico, New Toronto and Long Branch grew as their own towns along the lake long before the suburbs arrived. Mimico got a railway line in 1855 and the Grand Trunk’s Mimico Yards in 1906. New Toronto grew around factories such as the Goodyear plant built in 1916–17. Long Branch started as a summer resort, and in the 1920s the land around the mouth of Etobicoke Creek was subdivided for cottages and housing. The result is a mix of pre-war brick, small bungalows, former cottages that have been enlarged, and newer townhouses and condos.

The Humber and creek valleys

The Humber River forms Etobicoke’s eastern edge, and Mimico Creek and Etobicoke Creek cut through it too. Homes along these valleys tend to sit on sloped or wooded lots, with walkouts, big trees and drainage that runs toward the ravine.

The post-war suburbs

Much of central and northern Etobicoke, toward Rexdale, filled in fast after 1945. The City’s archives describe a planned suburb of broad roads, separate zoning, and homes with large driveways and garages. That means many brick bungalows and side-splits from the 1950s and 1960s, often with aluminum siding on gables, upper storeys or additions, and wide garage door frames that were wrapped in aluminum decades ago.

What the record shows: Etobicoke facts that shape your exterior

These checkable facts explain why lakeshore homes and post-war bungalows need different plans. Each comes from a source listed at the end of the page.

• Old towns, separate histories. Mimico became a police village in 1905 and an independent municipality in 1917. New Toronto was incorporated as a village of about 500 people in 1913 and became a town in 1920. Long Branch was incorporated as a village around 1930. All three joined the Borough of Etobicoke in 1967 and became part of the amalgamated City of Toronto in 1998.
• Building eras on the lakeshore. Small bungalows went up in Mimico in the 1920s, followed by four decades of family homes and low-rise apartments, then a townhouse boom in the 1990s and condos more recently. Little residential building happened in New Toronto until after the First World War.
• Explosive suburban growth. In the two decades after the Second World War, Etobicoke grew from fewer than 40,000 people to more than 200,000.
• Flood history. Hurricane Hazel in 1954 swept away 366 metres of Raymore Drive and 14 homes beside the Humber, killing 35 people. In Long Branch, more than 40 homes were lost at the mouth of Etobicoke Creek. Afterward, many floodplain areas became parkland, and the Toronto and Region Conservation Authority was created to manage floodplains.
• A largely private shoreline. Long Branch’s lakeshore is mostly privately owned, apart from Long Branch Park and Marie Curtis Park. Many homes there face the lake almost directly.
• Snow and rain. Toronto Pearson’s 1991–2020 normals show about 114.5 cm of snowfall, 806.8 mm of total precipitation and 147 days a year with measurable precipitation.
• Heavier downpours ahead. The City’s 2024 climate report projects more rain falling over short periods, and warns of more flooding and erosion risk. It also expects fewer freeze-thaw cycles overall as winters warm, though they may be squeezed into a shorter season.

Is it the lake or the road salt? What really wears out lakeshore exteriors

Lake Ontario is fresh water, so the lake itself is not salting your siding the way the ocean would. The damage near the lake comes from three things working together: wind, moisture and winter road salt.

Wind-driven rain

Open water gives wind a long run with nothing to slow it. Homes on or near the lake, especially those on south- and southwest-facing streets with nothing between them and the water, get rain pushed sideways into laps, corners and the gaps around windows. Water that would simply run off a sheltered wall is forced behind trim and capping.

Moisture that lingers

Lakeshore air is often damper, and fog and mist off the water keep walls wet for longer. On wood trim that was painted or poorly wrapped, that means rot at window sills, the bottoms of door frames and porch posts.

Road salt and spray

The salt problem is from the roads. Lake Shore Boulevard, the Gardiner and the QEW are salted all winter, and passing traffic throws brine onto nearby walls, garage doors and the bottom metre of siding. Salt speeds up corrosion of steel fasteners and attacks aluminum where it touches other metals.

What that means for materials

Aluminum itself handles lakeshore conditions well, because it does not rust or rot. The weak points are the details: fasteners that corrode, sealant that cracks, trim cut short, and aluminum sitting directly against copper, treated wood or plain steel. Good installation on the lakeshore is mostly about getting those details right.

8 priorities for homes in Mimico, New Toronto and Long Branch

These are the items we would put at the top of the list for an older lakeshore house. They are ordered roughly by how much damage they prevent.

1. Seal the windward walls first. Find the walls that take the weather, usually south and west, and start there. Capping, caulking and flashing on those walls protect more wood than the same work on a sheltered side.
2. Fix rotted window and door frames before capping. Former cottages and pre-war homes often have frames that were painted for decades, then wrapped over soft wood. The rot has to be cut out and replaced, then capped. Our window and door frame repair service covers that process.
3. Use fasteners that suit aluminum. Aluminum or stainless fasteners avoid the rust streaks and galvanic corrosion that cheap steel nails cause in salty, damp conditions.
4. Back-flash and seal the capping. Window and door capping should shed water outward, with the top piece lapped over the sides and sealed where it meets the frame. On windward walls, that detail is what keeps water out.
5. Replace siding with sound backing. Many lakeshore homes have layers: original wood clapboard, then older cement-based shingle or aluminum, then sometimes vinyl. When re-siding, the condition of what lies underneath matters. Have suspect older materials tested before tear-off.
6. Size eavestrough for downpours. Short, intense rain is expected to become more common. Seamless eavestrough with enough downspouts keeps water away from older foundations.
7. Close soffit gaps on enlarged cottages. Additions built at different times often leave odd soffit joints where roofs meet. Those are entry points for wind-driven rain, birds and squirrels.
8. Choose colours that hold up to sun and glare off the water. South-facing walls by the lake get strong sun. Quality factory-baked finishes in mid-tones hide chalking and fade more evenly than very dark colours.

7 upgrades that make the biggest difference on a 1950s–60s Etobicoke bungalow

Most post-war bungalows in central and northern Etobicoke are solid brick houses with tired trim. These upgrades give the most protection and visual change for the money, roughly in order.

1. New eavestrough and downspouts

Original or 1980s sectional gutters leak at the seams and sag. Seamless aluminum eavestrough, sized for the roof, with downspouts that empty well away from the foundation, protects basements that were never waterproofed to modern standards. See our eavestrough installation and repair page.

2. Fascia and soffit, done together

Bungalow overhangs are short, and many have wood soffit with a few small vents. Replacing it with vented aluminum soffit and re-wrapping repaired fascia improves attic airflow and closes animal gaps in one job. Our soffit and fascia page explains the options.

3. Window capping

Old capping on these homes is often dented, chalky or lifting at the corners, and some windows were never capped at all. New capping is bent to fit each opening and is one of the most visible improvements you can make.

4. Garage door frame capping

Etobicoke’s post-war homes were built around the car, and many have wide garage openings facing the street. The bottom of the wood jambs takes splash, salt and snow from the driveway. We measure the frame, cut and bend aluminum to fit, and attach it with adhesive and/or screws. More on our garage door frame capping page.

5. Siding on gables, upper storeys and additions

Where these homes have siding, it is often original aluminum that has faded, dented or lost its finish. Replacing it with new aluminum siding brings the whole house up to date.

6. Entry door frame capping

The front door frame is the first thing visitors see and often the most weathered. Capping it with the window trim gives the house a finished look.

7. Porch and front step trim

Many bungalows have small front porches or canopies with wood posts and fascia. Wrapping those in aluminum finishes the job, while any structural porch repair is scoped separately.

Repair, re-cap or replace: what to do with old aluminum siding

Old aluminum siding can often be repaired if the damage is limited, but once the finish is gone across a whole wall, replacement is usually the better value. The table below compares the three paths we discuss most with Etobicoke owners. Our aluminum siding installation and replacement page covers new siding in more depth.

How to tell which path you are on

Rub the siding with a damp cloth. A heavy white or coloured powder means the finish is chalking. Look for panels that have pulled loose at the bottom edge, and check whether dents cluster in one spot or appear across the whole wall. If more than a couple of walls look worn, replacement usually wins over patching.

Ballpark costs, worked through for typical Etobicoke jobs

The ranges below are typical GTA ballpark ranges (2026). Your written quote after an on-site measure is what counts. To make them more useful, we have worked through three illustrative examples using made-up quantities.

These are not quotes. On the lakeshore, rot found under old capping is the most common reason a trim job grows, at $150–$900 per opening. On two-storey homes and ravine lots, height and access push prices up. On post-war bungalows, low roof edges and easy driveways tend to keep labour on the lower side.

How to check your exterior after a big lake storm

A quick walk-around after a strong wind or heavy rain catches problems while they are small. You need about twenty minutes, a pair of binoculars and a flashlight.

Start on the windward side

Begin with the wall that faced the storm, usually south or west near the lake. Look for siding panels that have lifted at the bottom edge or popped out of a J-channel.

Look at every corner and opening

Check outside corner posts, the tops of window capping and the joint where capping meets brick. Any gap you can see is a gap that wind-driven rain can use.

Check the roof edge from the ground

Use binoculars to scan soffit for missing or pushed-in panels, and fascia for lifted seams. Look for eavestrough pulled away from the fascia or twisted at the corners.

Go inside and look up

Shine a flashlight around the inside of windows and in the attic near the eaves if you can reach it safely. Stains, damp insulation or daylight at the soffit line mean water or wind is getting in.

Write it down with photos

Take dated photos of anything you find. They help a contractor understand the problem before the visit, and they are useful for an insurance claim if the damage is storm-related.

What an Etobicoke siding replacement looks like, start to finish

A siding replacement on an older Etobicoke home follows a clear sequence. Here is what to expect.

1. Free estimate and measure. We measure each wall, note exposure and access, and check the existing cladding and trim. You receive a written quote that lists tear-off, any insulation board and capping separately.
2. Check older materials. On lakeshore homes with several layers of cladding, we flag anything that may need testing before removal, so it can be handled correctly.
3. Tear off and inspect the wall. Old siding comes off, and the sheathing and framing are checked. Soft or damaged areas are repaired before anything new goes on.
4. Weather barrier and flashing. House wrap goes on, lapped so water runs outward, with flashing above windows and doors. On windward walls this step gets extra attention.
5. Optional insulation board. If it is in your quote, insulation board goes over the sheathing to add a thermal layer and give the siding a flat base.
6. Starter strip, channels and corners. Starter strip, J-channel and corner posts are set straight and level, because everything that follows depends on them.
7. Siding panels. Panels are hung with room to expand and contract, fastened with corrosion-resistant fasteners, and cut cleanly around openings and fixtures.
8. Capping and trim. Windows, doors and the garage frame are capped with custom-bent aluminum to match. Our aluminum capping overview explains the trim work.
9. Final walk-through. We go over the job with you, clean up, and confirm the 5-year workmanship warranty in your written contract.

Humber valley and creek lots: extra care for slopes and trees

Homes along the Humber, Mimico Creek and Etobicoke Creek need a bit more planning, mostly because of slopes, trees and City rules. The work itself is the same, but access and protection take more thought.

Ravine rules come first

Toronto’s Ravine and Natural Feature Protection By-law prohibits, without a permit, harming or removing trees of any size in protected areas, changing slopes, or building or replacing structures. Outside those areas, the City still protects any private tree measuring 30 cm or more across at chest height. You can check whether your lot is covered on the City’s online map.

Plan access on sloped lots

Walkout bungalows on valley lots often have a full two-storey wall at the back. Ladders on a slope need level footing, and some jobs need staging. That affects the price, so it should be in the quote.

Handle drainage toward the ravine

Downspouts should not dump water where it can erode a slope. On ravine lots, we discuss where each downspout empties before the eavestrough goes up.

Plan for leaves

Valley lots get heavy leaf drop. Larger gutters, bigger downspouts and guards make sense here, much as they do on the treed streets of North York.

Spring checklist for Etobicoke homeowners

Winter is hardest on Etobicoke exteriors, whether from lake wind or salt from busy roads. Run through this each April.

• Hose off salt from the lower siding, garage door capping and door frames.
• Look for rust streaks, a sign of corroding steel fasteners.
• Check windward walls for lifted siding panels or loose corner posts.
• Inspect window and door capping for gaps at the top corners.
• Flush every gutter and confirm each downspout drains away from the house.
• Check soffit for panels pushed in by wind or animals.
• Probe the bottoms of door and garage frames for soft wood.
• On ravine lots, make sure downspouts are not eroding the slope.
• Photograph anything that needs attention and book repairs before summer.
