Scarborough Neighbourhood Home Inspection Guide — What We Find Most

Scarborough Neighbourhood Home Inspection Guide — What We Find Most

I'm standing in the basement of a 1989 semi on Finch Avenue East, and I'm looking at something I've seen maybe a hundred times in this neighbourhood. The homeowner is upstairs thinking everything's fine. The foundation wall in front of me has a horizontal crack running across it, water staining below, and the sump pump that's supposed to handle this is sitting silent in a pit filled with sediment. It's early June. The rainy season hasn't even started. I know exactly what's coming in three months.

This is Scarborough. This is what I do.

After fifteen years inspecting homes across the GTA, with the last eight focused heavily on Scarborough, I've developed a real understanding of what this borough throws at you. The MLS data tells you it's mixed: 67 active listings, average price sitting at $1,087,752, but what matters more to me is that risk score of 59 out of 100 and that 80.6% of the housing stock was built in the high-risk era. That's the 1980s and 1990s. That's aluminum wiring in some pockets. That's poly-B plumbing in others. That's foundation technology that wasn't quite figured out yet.

I want to walk you through what I actually find out here, neighbourhood by neighbourhood, because Scarborough isn't one place. Agincourt is completely different from Woburn. Milliken is completely different from Guildwood. And knowing the difference is how you avoid getting surprised after closing.

The housing stock in Scarborough breaks down into clear bands. From Agincourt up through Woburn and parts of Steeles, you've got a lot of 1975 to 1992 builds. Mostly detached and semi-detached homes, brick and aluminum siding. Lots of them have had kitchen and bathroom updates, which is good and bad. Good because the homeowner cares. Bad because you need to know if they pulled permits for that bathroom reno in 2007. Down in Guildwood and the Bluffs area, you're seeing older housing, some of it 1960s, 1970s builds. Those are different problems entirely. Around Kennedy and Scarborough Town Centre, there's more condo and townhouse density. More shared walls. Different failure points.

Let me start with Agincourt because it's where I spend a lot of time. The neighbourhood's been built out for forty years. I'm seeing foundation issues in about 35 percent of the homes I inspect here. The top five findings are basement water intrusion, sump pump failure or absence, exterior foundation cracks and seepage, missing or deteriorated eavestroughs, and roof condition issues on original asphalt shingles. When I find water damage in the basement, it's costing homeowners between $8,400 and $18,900 to properly address depending on whether it's interior drainage, exterior foundation work, or full waterproofing. That's a real number I've tracked across thirty inspections in the last two years.

Woburn, just north, has slightly different patterns. The housing is newer on average by maybe five years. I'm seeing less foundation water intrusion but more roof issues. Asphalt shingles installed in the late 1980s and early 1990s are simply failing now. You can't expect a $6,200 roof replacement to last more than thirty-five years in Ontario's climate. The top findings there are roof deterioration, furnace age and service history gaps, attic insulation missing in sections, windows needing replacement, and foundation cracks. That furnace cost I'm quoting is $7,150 for a mid-range unit installed properly.

Milliken's another story. Slightly more expensive homes, better maintained on average. I'm still finding water intrusion, but the owners tend to be more proactive. Top issues are eavestroughs and downspouts, basement dampness rather than active water, roof condition, attic ventilation inadequacy, and plumbing concerns - especially around drain tiles. The plumbing repairs here run $3,287 to $6,400 depending on scope.

Guildwood, the older neighbourhood down near the Bluffs, that's where I find more serious issues. Older foundations. Some homes with asbestos in insulation. Knob and tube wiring in the oldest pockets. Top findings: foundation cracks with water intrusion, electrical system concerns, asbestos materials present, furnace at end of life, and roof deterioration. These homes need more specialist work. An electrician's quote for updating a panel can hit $4,875.

Scarborough Town Centre area homes are dense and different. Condos and townhouses. Water intrusion still tops the list but it's often through the roof or shared walls. I find HVAC issues, water damage in units below affected units, foundation cracks, deck deterioration, and interior water damage near windows. Condo-specific repairs run differently because contractors charge premium rates. A roof repair in a townhouse complex might cost 30 percent more than the same work on a detached home.

Now, which streets do I recommend? Finch Avenue East has older stock but better maintained on average than the side streets running north from it. Sheppard Avenue East similarly. Both see more owner investment. I'd avoid the worst outcomes by inspecting carefully on the smaller streets running between them - McCowan, Midland, Birchmount. I'm not saying don't buy there. I'm saying be very careful. I've seen foundation issues cluster on certain blocks. The water table situation makes some areas riskier than others.

What do buyers consistently overlook in Scarborough? The sump pump. I mentioned it at the start. Buyers see it, think it's working, don't check when it last ran or if it's even wired properly. I've found sump pumps that are a decade old with no backup system in a neighborhood that floods every heavy rain. Second oversight is the eavestroughs. People think "that's just cosmetic." It's not. Improperly draining water is how you get foundation cracks and basement water. Third is attic ventilation. You can't see it. Most inspectors tell them it's fine. But inadequate ventilation causes premature shingle failure, ice dams, and moisture problems. Fourth is checking what era the electrical service is from and whether it's had updates. And fifth is the furnace. People buy an old furnace as part of the home and assume it's fine. A twenty-five-year-old furnace is at the end of life. That's not an opinion. That's how they're engineered.

Let me tell you about a real inspection from last fall, October, on Midland Avenue just north of Steeles. Semi-detached, built 1987. The buyers were young, first-time, and excited. The home showed well. Updated kitchen, nice bathroom, finished basement. But in that basement, I found water staining around the perimeter at foundation level, fresh staining, not old. The sump pump was installed in 1998. I ran the test. It didn't activate. I went outside. The grading sloped toward the house. The eavestroughs on the north side were disconnected and draining right into the foundation. I knew we'd found the reason for the water. But I also knew this wasn't just eavestroughs. The foundation had seepage. The buyers were disappointed. They wanted to renegotiate. The seller wouldn't budge. They walked away. Six months later I was back in that house - different buyers - and the foundation had leaked so badly over the winter that they had to excavate and waterproof. Cost them $16,740. That's what happens when you don't understand what you're looking at.
