Torch-on membrane application
Each job starts with a diagnosis. We match the system to your specific substrate, exposure, and problem, not what is fastest to apply.

Our Process
From first call to
10-year guarantee.
Most waterproofing failures happen during preparation, not application. Our process starts with an accurate diagnosis before anything is applied.
Site inspection
We visit your property, identify exactly what is causing the problem, and assess the existing surface condition. No charge, no obligation.
Written quote
You receive an itemised quote within 24 hours. What we quote is what you pay. No surprise additions once work starts.
Preparation
Proper preparation is what separates a job that lasts from one that fails in two years. We strip, clean, and prime before applying anything.
Application and sign-off
We apply the correct system for your surface. You sign off on the completed work and we issue your 10-year guarantee certificate on the spot.

“We had three other contractors look at our flat roof over two years. None of them solved it. ShieldSeal found the problem in an hour and fixed it properly. Twelve months later, no leaks.”
Patricia Mhlongo
Property owner
Randburg, Gauteng
“The damp in my bedroom had been getting worse for years. I was told I needed a full renovation. ShieldSeal treated it correctly from the outside and it has been dry ever since. Should have called them first.”
James Oosterberg
Facilities manager
Midrand, Gauteng
“We use ShieldSeal across three commercial properties. Their maintenance programme means we catch problems before they become emergencies. Reliable, professional, and they actually pitch up when they say they will.”
