Deck and Balcony Inspection — Structural Safety and Code Compliance

Decks collapse. It happens in Ontario every summer. Here is what inspectors check for structural integrity and building code compliance.

Standing in the driveway on Plains Road last Tuesday, I heard it before I saw it - that distinctive grinding sound of a garage door opener fighting for its life. The homeowner just shrugged and said "it's been making that noise for months." When I hit the wall switch, the door lurched up about two feet before the cable snapped, and twenty-four hours later my buyers were looking at a $2,340 repair bill they never saw coming.

You'd think after 15 years of inspecting Burlington homes I'd stop being surprised by what people ignore about their garages. But here we are in 2024, and I'm still finding the same problems in these 1960s to 1980s builds that could've been caught with a ten-minute walk-around.

What I find most concerning isn't the big obvious stuff - it's how buyers treat garages like they're bulletproof storage sheds instead of integral parts of their $920,000 investment. That detached garage behind your Aldershot bungalow? It's probably original to the house, which means it's seen four decades of Burlington winters, and trust me, it shows.

Let me walk you through what I actually look for when I inspect these garages, because the devil's always in the details you can't see from the street.

Foundation issues hit me right away. These older garages in Tyandaga and the downtown core were built when building codes were suggestions more than requirements. I've seen concrete slab floors that have settled so badly the garage door won't close properly. Cost to level and pour a new slab? You're looking at $4,850 minimum, and that's if we don't find bigger drainage problems underneath.

The door systems themselves tell stories. Original overhead doors from the 1970s weren't designed to handle today's automatic openers. I see this constantly - someone bolted a modern opener to a door and track system that can't handle the stress. Springs fail, tracks bend, and suddenly you're dealing with a $1,680 replacement instead of routine maintenance.

But here's what really gets me fired up - electrical work that would make your insurance company weep.

These garages were wired when a couple of outlets and overhead lighting seemed plenty. Now they're powering electric vehicle chargers, workshop equipment, and smart home systems. I opened an electrical panel in a Fairview garage last month and found three different decades of DIY additions. Guess what we found? Aluminum wiring connected to copper with wire nuts, circuits overloaded by 40%, and a subpanel that hadn't been properly grounded since the Carter administration.

Buyers always underestimate how expensive proper electrical upgrades cost. Bringing a 1970s garage up to current code for EV charging runs $3,240 to $5,890 depending on distance from your main panel. That's assuming we don't find knob-and-tube wiring lurking behind those pegboard walls.

Structural issues show up differently in attached versus detached garages. Attached units share load-bearing walls with your house, so when I see settling cracks or sagging roof lines, we're potentially talking about problems that affect your entire structure. That hairline crack above the garage door opening? In 15 years I've never seen those stay hairline.

Detached garages have their own headaches. They settle independently from your house, which means different moisture patterns, different foundation stresses, and drainage issues that sneak up on you. I inspected a Plains Road property where the garage foundation had dropped six inches on one corner. The repair estimate came back at $8,760, and that was before we addressed the roof damage the settling caused.

Roofing deserves its own conversation because these garage roofs take abuse. They're usually lower priority for maintenance, they collect debris from overhanging trees, and in Burlington's climate they deal with ice damming every winter. Asphalt shingles from the 1980s are living on borrowed time by now.

What surprises people is how water damage spreads in garages. You might think a little roof leak isn't serious because it's "just the garage." But water finds wall cavities, rots sill plates, and creates perfect conditions for mold growth. I've seen garage repairs hit $12,450 because a $400 roof patch got ignored for three seasons.

Door and window security gets overlooked constantly. These older garages have side doors with original hardware that wouldn't stop a determined teenager. Windows are single-pane, frames are wood that's dried and shrunk, and locks are decorative at best. Your insurance company cares about this stuff, especially if you're storing anything valuable.

Ventilation matters more than most people realize. Modern garages store everything from paint cans to lawn equipment, but they're ventilated like empty boxes. Carbon monoxide from vehicles, chemical fumes from storage, and moisture buildup all need somewhere to go. Building codes have changed dramatically since these garages were built.

I always check for evidence of previous repairs too. Patches in concrete floors, mismatched siding, or fresh paint in odd spots usually mean someone addressed a problem without fixing the cause. Sound familiar? That beautiful fresh drywall might be hiding water damage or structural repairs that weren't done properly.

Come spring 2026, you'll want this sorted before our next wet season hits. Burlington weather is hard on these older structures, and problems multiply fast once water gets involved. Give me a call before you close on that Plains Road charmer - I'd rather find these issues now than get your frantic call six months later.
