Buying in Markham in July — What To Watch For

If you're buying in Markham this July, here's what Aamir will be checking:

AC performance and efficiency

Inspector checks: Temperature differential test, refrigerant line inspection, condenser coil condition

AC systems reveal problems under peak load — weak cooling now means failure in a heat wave

Attic ventilation and heat buildup

Inspector checks: Attic temperature reading, soffit and ridge vent inspection

Poor ventilation traps heat — accelerates roof aging and drives up cooling costs

Exterior grading and drainage

Inspector checks: Grade slope measurement, downspout extension check, swale inspection

Summer storms reveal drainage problems — water pooling against foundation causes long-term damage

Deck and exterior deterioration

Inspector checks: Deck joist inspection, railing stability test, ledger board connection

Summer is when deck failures happen — rotted joists and loose railings are safety hazards

Why a Home Inspection is Non-Negotiable in Markham

With homes selling in 59.4 days on average, buyers in Markham have limited time for due diligence. A pre-offer inspection removes uncertainty before you bid — giving you confidence to compete without waiving conditions.

12.6% of Markham's active listings fall in the highest-risk build era for aluminum wiring and poly-B plumbing. These are not cosmetic issues — they affect insurance eligibility and resale value. An RHI certified inspector identifies these before you sign.

At an average price of $1,368,862, a $349 inspection can identify $10,000–$50,000 in issues before you close. In Markham's market, that's negotiating power — or the confidence to walk away.

Latest Market Report for Markham

Written by Aamir Yaqoob, RHI

Hey there! So you're looking at buying in Markham? Smart move, honestly. I've been doing home inspections across York Region for fifteen years now, and Markham keeps me pretty busy. Just this June 2026, I've probably crawled through more attics and basements in Markham than I care to count, but that's exactly why I love what I do. Let me tell you what I'm seeing out there right now. The Markham market is absolutely wild. We're looking at 610 active listings with an average price sitting at $1.39 million, and honestly, most of the homes I'm inspecting are pushing well over $1.3 million. What really gets me is how fast things are moving. The average days on market is only 20, which means you're competing hard and making decisions quickly. That's exactly when you need someone like me in your corner. The thing about Markham homes is that most of what I inspect was built in the 1990s and 2000s. These aren't your grandfather's post-war bungalows. We're talking about homes that are hitting that 25 to 35-year mark where major systems start showing their age. I was just in Unionville last week looking at a gorgeous executive home from 1998, and the owner was shocked when I found the original HVAC system was on its last legs. That's a $12,000 to $18,000 replacement right there. Here's what keeps coming up in my Markham inspections. First, those aging HVAC systems I mentioned. When you're looking at homes from the late 90s and early 2000s, the furnaces and air conditioning units are often original equipment. I'm finding units that are running but inefficient, and some that are actually safety concerns. Just last month, I found a cracked heat exchanger in a Thornhill home that could have been a carbon monoxide issue. That's not just a $15,000 furnace replacement, that's potentially life-threatening. Second issue I see constantly is plumbing. Those 1990s builds in Markham often have the original plumbing, and I'm finding a lot of homes where the main water line is starting to fail. Copper pipes from that era are developing pinhole leaks, and don't get me started on the plastic fittings that were popular then. I inspected a place in Wismer just two weeks ago where the seller had been dealing with slow leaks for months without realizing it. The buyers were looking at $8,000 to $12,000 for partial re-piping. Third, roofs. With homes hitting the 25-year mark, original asphalt shingles are at the end of their lifespan. The freeze-thaw cycles we get here in Ontario are brutal on roofing materials. I'm seeing everything from missing shingles to full granule loss, and some homes where the flashing around chimneys and vents is completely shot. A full roof replacement in Markham is running $18,000 to $25,000 depending on the size and complexity. Fourth, and this one surprises a lot of people, foundation settlement. Some of the older subdivisions in Markham were built on clay soil, and I'm finding minor settlement issues that can become major problems. Hairline cracks in basement walls, doors that don't close properly, small gaps where the foundation meets the house. Most of these aren't structural emergencies, but they need monitoring and sometimes intervention. Depending on what we find, you could be looking at $5,000 to $15,000 for proper remediation. Now, if you're looking at anything older in Markham, we get into the really fun stuff. Some of the heritage properties and older homes still have knob-and-tube electrical wiring, which is not just outdated, it's often a insurance nightmare. I still find plaster walls that look beautiful but hide all kinds of issues. Cast iron drain pipes that are corroded from the inside out. Stone foundations that have been patched and re-patched over the decades. And yes, lead paint, especially on any trim work or windows that haven't been updated. What's interesting about June 2026 is that this is prime inspection season. The weather's good, I can really see what's happening with drainage around properties, and any ice dam damage from last winter is obvious now. This time of year, I'm paying extra attention to grading around homes, checking that downspouts are directing water away from foundations, and looking for any signs that the spring melt caused problems. I'm also checking air conditioning systems hard right now because we're just getting into the season where they'll be working overtime. Nothing worse than moving into your dream home in July and finding out the AC can't keep up or worse, breaks down completely. You know what gets me about this market? With things moving so fast and prices so high, I'm seeing buyers who feel pressured to skip inspections or accept properties as-is. That's roughly 71% of properties in Markham that I'd consider higher risk just based on age and common issues. The risk factors I look at put the average Markham home at about 51 out of 100 on my risk scale. Look, I get it. When you're competing against multiple offers on a $1.4 million home, you want your offer to stand out. But think about it this way. Even a $500 inspection fee could save you thousands down the road, and more importantly, it gives you the knowledge to make a smart decision about the biggest purchase of your life. Trust me, I'd rather help you understand what you're buying than get a call from you six months later when something major goes wrong. That's just how I've always done business here in Markham.

What Markham buyers are asking us

How much should I budget for a home inspection in Markham?

In Markham, home inspections typically cost between $500-$800 depending on the property size and age. Given that the average home price in Markham is $1.3M+, this inspection fee represents a small but crucial investment to identify potential issues before purchase. The cost may be higher for larger properties or homes requiring specialized inspections for older systems.

What are the most common issues found during home inspections in Markham?

The most frequent issues discovered in Markham home inspections include aging HVAC and plumbing systems, particularly in homes built during the 1990s housing boom. Roof wear from harsh Ontario winters is also common, along with foundation settlement issues in Markham's older subdivisions. These problems can be costly to repair, making professional inspection essential in this high-value market.

Should I be concerned about foundation issues when buying in Markham's older neighborhoods?

Yes, foundation settlement is a notable concern in Markham's older subdivisions, particularly those developed in the 1970s and 1980s. Clay soil conditions common in parts of Markham can contribute to foundation movement over time. A thorough inspection will identify signs of settlement, cracks, or water infiltration that could lead to expensive repairs on your $1.3M+ investment.

Are HVAC systems a major concern for homes built in Markham during the 1990s?

Absolutely. Many 1990s-built homes in Markham are now experiencing HVAC system failures as these systems reach the end of their 20-25 year lifespan. Given Markham's extreme temperature variations, replacing heating and cooling systems can cost $8,000-$15,000+. A pre-purchase inspection will assess system condition and help you budget for potential replacements in this premium housing market.

How long does a typical home inspection take in Markham, and when will I get the report?

Home inspections in Markham typically take 2-4 hours depending on the property size, with many homes being larger given the $1.3M+ average price point. Most inspectors provide detailed reports within 24 hours, which is crucial for meeting Markham's competitive offer timelines. The report will include photographs and prioritized recommendations for any issues found, such as roof wear or aging building systems.
