Markham Home Inspection Market Report — April 2026

April in Markham has been quite the roller coaster this year, and I'm seeing patterns that honestly have me a bit concerned for both buyers and sellers. The spring market rush is definitely here, but it's coming with some serious inspection challenges that you need to know about.

Last week I was in a home on Castlemore Avenue in the Angus Glen area, a beautiful 1990s build that looked pristine from the street. The sellers had it priced just under $1.4 million, right in line with what we're seeing across Markham this April 2026. But once I got into that basement, we found water seepage along the foundation wall that the homeowners had been quietly managing with a dehumidifier for years. The spring snowmelt had revealed grading issues that were directing water straight toward the house. That's a $8,500 fix minimum when you factor in proper drainage and waterproofing.

This is exactly what I'm seeing all over Markham right now. With 610 active listings on the market, there's more choice than we've had in years, but buyers are moving fast. Twenty days on market means you're making decisions quickly, and that's where people get into trouble. You can't rush a proper inspection, especially not in a market where 71% of the homes were built during what I call the high-risk era.

The Unionville and Thornhill areas are particularly tricky right now. These gorgeous mature neighborhoods have homes from the 1990s and early 2000s that are hitting that sweet spot where major systems start needing attention. I've inspected three homes on Warden Avenue this month alone where the original HVAC systems were on their last legs. The owners knew it, the real estate agents suspected it, but in this fast-moving market, some buyers were ready to overlook it just to get a deal done.

What worries me most is the foundation work I'm seeing. Markham's clay soil has been particularly active with all the freeze-thaw cycles we've had, and homes in areas like Wismer and Berczy Village are showing settlement issues. These aren't always deal-breakers, but they need professional evaluation. I had one couple almost walk away from a home on Ninth Line because of some minor foundation cracks, but after getting a structural engineer involved, we determined it was cosmetic settling that could be monitored rather than immediately repaired.

The electrical systems in these 1990s homes are generally solid, which is good news compared to some of the older Toronto neighborhoods I work in. But I am seeing more panel upgrades needed, especially in homes where previous owners added pools, hot tubs, or workshop spaces without properly upgrading the electrical service. In Buttonville and the older parts of Markham Village, some homes still have remnants of older wiring that needs attention.

Plumbing is where things get interesting. Most Markham homes from this era have decent copper plumbing, but I'm finding more lead service lines than expected, especially in the established neighborhoods around Highway 7 and McCowan. The municipal infrastructure in some pockets is older than you'd think, and that affects what's coming into your home. It's not a crisis, but it's something to test for and potentially address.

The spring market energy is definitely here, and sellers are taking advantage. Average prices holding steady above $1.3 million means these aren't impulse purchases for most families. But I'm seeing buyers who are so focused on getting into their dream neighborhood that they're not fully grasping what they're taking on. Richmond Green and Rouge River Estates have some absolutely stunning properties, but some of these larger homes have maintenance requirements that can surprise new owners.

HVAC systems are my biggest concern this season. The heating systems got a real workout this winter, and I'm finding more failures than usual during inspections. It's not uncommon to need a new furnace or significant ductwork repairs in a home from this era. The good news is that most Markham homes have proper ductwork layouts, so replacements are straightforward even if they're expensive.

Roof conditions have been surprisingly good overall. Most homes in Markham were built during a period when roofing materials and installation practices were pretty solid. But I am seeing more ice dam damage from this past winter, especially on homes with complex rooflines in the newer subdivisions around Major Mackenzie Drive.

What strikes me about April 2026 in Markham is how sophisticated buyers have become. People are asking better questions during inspections, they understand that a 25-year-old home needs maintenance, and they're budgeting accordingly. The days of buyers expecting a move-in ready home at this price point are mostly behind us.

The market feels stable but busy. Twenty days on market gives you time to do things right if you're organized. Get your financing sorted early, book inspections quickly, and don't be afraid to ask for time to review major issues properly. The sellers I'm working with are generally reasonable about repair negotiations when the problems are legitimate.

If you're buying in Markham right now, budget for the reality of home ownership in this price range and age category. These are quality homes in fantastic neighborhoods, but they need attention and maintenance like any property. The key is knowing what you're getting into before you sign, not discovering it six months later when your basement floods or your furnace dies on the coldest day of winter.

Stay smart out there and don't let market pressure rush you into skipping the important steps.
