Buying in Clarkson in June — What To Watch For
If you're buying in Clarkson this June, 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
