Door Inspection — Exterior Doors, Weatherstripping, and Security

I'm standing on James Street North last Tuesday, staring at what the sellers called "recently updated siding" on a 1920s brick colonial. The aluminum panels were buckling near the foundation, and when I pressed my hand against the wall, I could feel it give way like a sponge. The musty smell hit me before I even started pulling back the loose corner. Guess what we found underneath?

Water damage. Lots of it. The original brick had been crying for help for months, maybe years, but nobody was listening.

After 15 years of inspecting homes across Hamilton, I've seen every cladding type you can imagine on these older properties. The 1900s to 1960s builds in neighbourhoods like Westdale and Dundas showcase an incredible variety of exterior materials, and buyers always underestimate how much the wrong choice can cost them down the road.

Let me be clear about something - not all cladding is created equal. What I find most concerning is when homeowners choose materials based purely on upfront cost or curb appeal, completely ignoring how they'll perform in Ontario's brutal climate cycles.

Brick veneer dominated Hamilton construction from the 1920s through the 1950s, and there's good reason for that. I've inspected hundreds of these homes in Locke Street area and beyond, and properly maintained brick still looks fantastic after eight decades. The thermal mass helps with energy efficiency, it's fire resistant, and it can handle our freeze-thaw cycles better than most modern alternatives. But here's what surprises people - even brick needs attention. Mortar joints deteriorate, especially on the south and west faces that take the brunt of weather. Repointing costs around $3,200 for a typical two-story home, but ignore it and you're looking at $12,400 in structural repairs when water starts penetrating behind the veneer.

Wood cladding tells a different story entirely. The cedar shingles and clapboard siding I see on 1930s homes in Dundas can be absolutely gorgeous when maintained properly. Sound familiar? That's the key phrase - when maintained properly. Wood needs to be cleaned, sealed, and painted every four to six years in our climate. Skip this maintenance cycle and you'll face rot, insect damage, and paint failure that runs $8,750 to remedy on average.

Aluminum siding became popular in the 1960s as a "maintenance-free" solution. I put that in quotes because nothing is truly maintenance-free, and aluminum proves this point regularly. It dents easily, fades over time, and here's what most people don't realize - it expands and contracts significantly with temperature changes. Those expansion joints you see? They fail. When they do, water gets behind the siding and you've got problems you can't see until it's too late.

Vinyl siding started appearing on Hamilton homes in the 1970s and 1980s, often as a retrofit over original materials. What bothers me most about vinyl is how it hides problems. I've pulled back loose vinyl panels to find rotted wood sheathing, damaged vapor barriers, and insulation that's been wet for months. The vinyl itself might look fine from the street, but it's what's happening behind it that keeps me up at night. Replacement costs for properly installed vinyl with adequate insulation and vapor barrier runs about $14,750 for a typical 1,500 square foot home.

Stucco over masonry block was another popular choice for 1950s construction, especially on ranch-style homes. Done right, it creates a durable, attractive finish. Done wrong, and you've got cracks that channel water directly to your foundation. I inspected a home on King Street East last month where poor stucco application led to $6,300 in foundation repairs.

Here's something that might surprise you - I'm seeing more and more composite materials on older homes as people renovate. Fiber cement siding, engineered wood products, and synthetic stone veneers all promise low maintenance and long life. The jury's still out on how these materials will perform over decades, but early indications are positive if they're installed correctly. Installation is everything with these products. Cut corners on flashing, vapor barriers, or fastener patterns, and you'll have problems regardless of how good the material itself might be.

The spring weather we expect in April 2026 will test every cladding type differently. Wood will swell and contract. Vinyl will expand. Brick mortar will absorb moisture and potentially freeze. Metal siding will conduct temperature changes directly to the sheathing behind it.

What I tell every buyer is this - look beyond the surface. That beautiful brick exterior might be hiding pointing that needs immediate attention. Those perfect vinyl panels might be concealing moisture damage from poor installation five years ago. Ask about maintenance records. When was the last time the siding was properly cleaned and inspected? Are there any warranty documents for recent work?

In 15 years, I've never seen a cladding material that performs well without proper installation and regular maintenance. The material matters, but the workmanship matters more.

You're buying a home in Hamilton with decades of weather exposure behind it and decades more ahead of it. Get that exterior cladding properly inspected before you sign anything. Your future self will thank you for it.
