Settlers Park and groundwater
Houses near German Mills Settlers Park and the creek valley often have weeping tile that runs for long periods after snowmelt. A sump pump that runs steadily in March is normal there, but it shortens the pump’s life, so we suggest a quality primary pump and a backup. We also look at exterior grading and downspouts, which can send roof water straight back to the foundation and keep the pump working harder than it needs to.
Markham note: village-core houses tend to hide cast iron and galvanized behind plaster, while Cornell and Box Grove builds run PEX to a manifold. We ask the year your house was built so the right fittings ride along on the truck.
Straight from the phone log
Does living near a ravine affect my basement?
It can raise groundwater. A working sump system and good grading matter more here.
Must you cut drywall to find a leak?
Usually not at first; we use the meter and acoustic listening to narrow the spot.
