Leak Detection in Markham.
Rising water bills, damp spots, a running meter, or low pressure with no clear cause? Our team finds hidden leaks without tearing your home apart, then repairs them.
We use non-invasive detection to pinpoint leaks behind walls, under floors, and in slabs before they cause real damage. Catching a hidden leak early saves the drywall, the floor, and the bill.
