Dave and Reay, the founders of One Call Weep Hole Covers SA, bring a combined 100 years’ experience in the roofing, painting, and plumbing industries.
Over the years, they noticed a clear pattern. Many damp issues and related damage could be traced back to one overlooked detail: unprotected weep holes. When moisture and pests enter through open weep points, wall cavities can stay damp for longer. Over time, that dampness can contribute to wall damage and may affect nearby building materials, including timber in roofing.
They set out to create a solution that was simple, effective, and affordable for homeowners. The result is a unique patented weep hole cover with a protective grid design. It helps reduce insect entry, minimise rainwater ingress into wall cavities, and keeps a neat, low-profile finish.
It’s also designed for South African conditions. During winter, it adds protection against water ingress during heavy rainfall and wind-driven splash. During the summer fire season, it provides an extra barrier against airborne fire embers entering through weep openings.
After consulting with industry professionals and testing prototypes in real-world conditions, Dave and Reay launched what they believe to be South Africa’s only insect-proof weep hole cover—created to help property owners avoid unnecessary maintenance and costly repairs.
Our Solution
One Call Weep Hole Covers block the trouble at the opening
Our weep hole covers use a practical grid design. The grid acts as a barrier at the face of the weep opening. It helps reduce the size of what can enter. It also helps reduce splashing and direct entry during wind and rain.
This is a simple improvement. It’s also a smart one. It protects a vulnerable point on many homes. It does it without changing the clean look of the wall.
