I pulled into the driveway on Apple Creek Boulevard last Tuesday morning, and the sweet smell of rot

I pulled into the driveway on Apple Creek Boulevard last Tuesday morning, and the sweet smell of rotting wood hit me before I even opened my car door. The sellers had been running a humidifier in the basement for weeks, trying to mask what I'd find downstairs — a foundation crack so wide you could slide a pencil through it, with water stains stretching eight feet up the concrete wall. The house was listed for $1,425,000, and my buyers were already talking about which wall to knock down for their dream kitchen. I've seen this story play out too many times in my 15 years doing this job.

Here's what buyers always underestimate about these Markham homes built in the 1990s and early 2000s — they're hitting that sweet spot where everything starts breaking at once. The furnace that seemed fine during the summer showing? It's probably got a cracked heat exchanger that'll cost you $8,200 to replace come October. The roof that looks decent from the street? I climbed up there and found three layers of shingles, with the bottom layer from 1994 completely shot.

In my experience, what I find most concerning isn't the big obvious stuff. It's the shortcuts I see in these subdivisions off Highway 7. Last week on Cedarland Drive, I found electrical work that made my hair stand on end — aluminum wiring spliced with copper, buried junction boxes, and a main panel that belonged in a museum. The quote to bring it up to code? $14,750. Sound familiar?

You know what really gets to me? Walking through these beautiful homes with families who've saved for years to afford Markham's average price of $1,390,840, watching them fall in love with granite countertops while I'm calculating how much the failing sump pump is going to cost them. I opened a basement door on Bur Oak Avenue last month, and water was actually pooling around the foundation. The sellers' agent kept talking about the "character" of the home while I'm thinking about the $12,400 waterproofing job these buyers are walking into.

The market moves fast here — 20 days average, 610 homes to choose from — and that pressure makes people skip steps they shouldn't skip. I've had clients tell me to rush my inspection because they're afraid someone else will snatch their dream home. But in 15 years, I've never seen rushing work out well for the buyer.

What really worries me about some of these Unionville properties is the HVAC systems. These homes are pushing 25-30 years old now, and I'm seeing ductwork that's never been cleaned, furnaces running on borrowed time, and central air units that sound like freight trains. Just last Friday on Woodbine Avenue, I found a furnace with a gas leak so bad I had to shut off the main valve before we finished the tour. The sellers had no idea, but that family would've been dealing with a $9,800 replacement bill within their first month.

Here's my take after all these years — the nice neighborhoods don't protect you from bad maintenance. Some of the worst foundation issues I've documented have been in million-dollar homes where the previous owners figured expensive meant maintenance-free. Water finds a way, and in these clay soils around Markham, it finds a way fast.

I remember inspecting a house on Carlton Road where everything looked perfect from the curb. Fresh paint, manicured lawn, even the driveway was recently sealed. Then I got into the crawl space and found joists so rotted I could break pieces off with my bare hands. Structural repairs ended up costing the new owners $18,200, and that was after they'd already closed.

The electrical systems in these homes tell stories too. I've found panel boxes in basements that have been flooding for years, with rust eating through the connections. Federal Pacific panels that should've been replaced decades ago. Knob and tube wiring hidden behind fresh drywall. These aren't small fixes — you're looking at $11,500 to $16,000 to do electrical right.

But here's what keeps me going after 3-4 inspections every single day, even when I'm exhausted — it's those moments when I catch something that could've destroyed a family's finances. Like the house on Major Mackenzie where I found structural damage that three other people had missed. Or the beautiful colonial on Ninth Line where the previous inspector had signed off on plumbing that was literally backing up into the basement.

Buyers ask me about Markham's risk score of 51 out of 100, and honestly, that number doesn't tell the whole story. The risk isn't in the neighborhood — it's in assuming that expensive homes don't have expensive problems. The risk is in falling for staging and fresh paint when the bones of the house are telling you something different.

April 2026 will mark my 17th year doing this work, and I still see the same mistakes. Buyers who skip the inspection because they're afraid of losing the house. Families who budget for the down payment but not for the $15,000 in immediate repairs I find in my report. People who trust that previous owners took care of everything when half the time, previous owners didn't even know what was wrong.

The houses I inspect in Markham are beautiful, and most families will be happy here if they go in with eyes wide open. But don't let the manicured neighborhoods and million-dollar price tags fool you into thinking these homes don't need the same careful inspection you'd do anywhere else. Schedule your inspection, ask the hard questions, and budget for what I'm probably going to find.
