Balconies in the Hills District are often newer, on townhouses and family homes, but the same clay-soil movement that affects house slabs also stresses balcony membranes.
Our technicians repair leaking balconies across Castle Hill and the wider Hills District using commercial-grade epoxy grout and perimeter re-detailing — no demolition in most cases, with a written 10-year warranty.
Castle Hill properties face unique waterproofing challenges. Clay-rich soils in the Hills District cause significant building movement, leading to cracked grout and stressed membranes. We use flexible waterproofing systems designed to accommodate this movement.
The area is dominated by family homes built since the 1980s, with significant new estate growth in the past 15 years. Newer homes often have framed walls and concrete balconies that are sensitive to ground movement, leading to membrane and grout cracks.
A common Hills District scenario: a newer townhouse balcony with hairline grout cracks and water tracking onto the room below. Typically resolved by epoxy regrouting and re-detailing the perimeter without tile removal.
