I walked into the basement on Willoughby Road last Tuesday and immediately smelled that musty, sweet

I walked into the basement on Willoughby Road last Tuesday and immediately smelled that musty, sweet odour that makes my stomach drop – active mold behind finished drywall. The homeowner had painted over water stains on the foundation wall, but you can't hide that smell from someone who's been doing this for 15 years. When I pulled back the corner of the drywall with my moisture meter screaming, black mold covered nearly eight feet of concrete block. The buyers were planning to close in three days.

Sound familiar? This is what I'm seeing more and more in Caledon East, where buyers are so desperate to get into the market at that $800,000 average price point that they're waiving inspections or rushing through them. I've got news for you – these 26-year-old homes aren't aging gracefully, and what I find most concerning is how many major issues are being covered up with quick cosmetic fixes.

Just last week on Centreville Creek Road, I found a furnace that was literally held together with duct tape and hope. The heat exchanger had a crack you could slide a quarter through, pumping carbon monoxide into the house every time it cycled. The seller's disclosure said "furnace recently serviced." Recently serviced, my foot. That unit needed $4,200 in immediate repairs just to be safe, never mind efficient.

Here's what buyers always underestimate about Caledon East homes – the well and septic systems. I can't tell you how many times I've watched buyers fall in love with a property on Mono Mills Road or Boston Mills Road without considering that their water comes from 150 feet underground and their waste goes into a tank buried in the backyard. When that septic system fails, and trust me, in homes built in 1998 they're starting to fail, you're looking at $8,500 to $12,000 for a complete replacement. That's assuming you've got good soil conditions, which half these properties don't.

The electrical systems in these homes make me lose sleep. I inspected a beautiful colonial on Hurontario Street last month where someone had added three circuits to a panel that was already overloaded. Federal Pacific panels from the late 90s weren't great to begin with, but when you've got a previous owner playing electrician, you're asking for trouble. The scorch marks around two of the breakers told me everything I needed to know. The buyers were looking at $3,800 just to bring the main panel up to code, never mind the aluminum wiring I found in the addition.

What really gets to me is the foundation work I'm seeing. These houses went up fast during the building boom, and it shows. I've found step cracks in basement walls that homeowners tried to patch with hydraulic cement, thinking that would solve water infiltration. Guess what we found when it rained the next week? Water streaming down the inside of the foundation wall like a waterfall. Foundation repair in this area runs $6,200 to $11,500 depending on how much underpinning you need, and that's with decent access for equipment.

The roof work in Caledon East is keeping contractors busy, that's for sure. April 2026 will mark nearly 30 years for some of these original shingles, and I'm already seeing failures. Three-tab shingles that were supposed to last 20 years are curling, cracking, and letting water into the decking. I found rot in the roof decking of a house on Regional Road 136 that the listing photos made look pristine. The seller had replaced maybe 40 shingles on the front slope – the side you see from the street – while the back slope looked like a hurricane hit it.

In my opinion, the HVAC systems in these homes are the most neglected components I encounter. Ductwork that's never been cleaned, filters that haven't been changed in months, and furnaces that are running on borrowed time. I opened up a gas furnace on Creditview Road where the previous owner had bypassed two safety switches because they kept shutting the system down. Those switches shut things down for a reason – usually because something dangerous is happening with combustion or heat exchange.

Buyers need to understand that a home inspector isn't just checking boxes on a form. I'm trying to keep you from making an $800,000 mistake. When I recommend getting a structural engineer to evaluate those foundation cracks, or a roofing contractor to assess that suspicious staining on the ceiling, it's because I've seen what happens when people ignore these red flags. The house on Airport Road that I inspected two years ago needed $23,000 in foundation work six months after closing. The buyers thought I was being overly cautious.

The plumbing in homes around Terra Cotta and Inglewood shows its age too. Original copper supply lines are developing pinhole leaks, and the galvanized drain lines are corroding from the inside out. I've pulled drain cleanouts that crumbled in my hands. When your main drain line fails under the basement floor, you're looking at $5,400 minimum for excavation and replacement. That's assuming they don't hit any surprises under the concrete.

Here's my take after 15 years of crawling through basements and attics – there's no such thing as a perfect house, but there are plenty of houses with problems that'll bankrupt you. The key is knowing what you're getting into before you sign on the dotted line. I'd rather have you walk away from a house in Caledon East than watch you struggle with repair bills for the next five years. Call me before you waive that inspection condition – your future self will thank you.
