Buying in Markham in May — What To Watch For
If you're buying in Markham this May, here's what Aamir will be checking:
Spring flooding and basement moisture
Inspector checks: Moisture meter readings on all basement walls, sump pump test
Snowmelt saturates soil — hydrostatic pressure pushes water through foundation cracks
Roof damage from winter
Inspector checks: Drone roof assessment for missing shingles, flashing damage, ice dam remnants
Winter ice and wind remove shingles and break flashing seals — leaks follow in spring rains
Foundation cracks from frost heave
Inspector checks: Foundation wall survey for new or widened cracks
Frost heave can shift foundations — new cracks after winter signal structural movement
Sump pump readiness
Inspector checks: Float switch test, discharge line inspection, backup power verification
Spring is peak demand — sump pump failure during snowmelt causes catastrophic flooding

71.1% 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 $1,390,840, 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.
