Leaky gutters will cost you more than just money
It can cause serious water damage to your property and rack up costly repairs.
Especially if you don’t fix the real cause behind the leaky gutters.
If you own a commercial, industrial, or even older building
Your gutters might not hang off the edge like most. They might be built into the roofline itself.
They’re called box gutters and most property owners don’t even know they have them.
This is because, the gutters aren’t hanging off the edge like a standard setup.
They’re built into the roof structure itself
Long, shallow metal troughs built into your roofline, hidden just above your ceiling.
They’re designed to catch and drain water before it causes damage.
But when your Box Gutters start to leak, it can lead to:
-
Shut down departments. Missed deadlines. Everything on pause.
-
Furious tenants and legal threats.
-
Mold, rot, and water damage eating your ceilings
-
Empty rooms. Lost rent. Tenants threatening to leave.
-
Emergency repairs that cost 3X more
Knowing what’s actually causing your leaky gutters is the difference between another patch and a lasting fix.
Get a full gutter inspection, so you can fix it properly, not just patch it.
Book now before the rain makes it worse.

What Happens If You Ignore the Leak?
1. Equipment can get damaged
Critical equipment gets fried. Electrical systems short. Data lost. Tenants demand compensation, fast.
2. Mould can start to form
Mold spores in the vents. Health complaints pile up. Suddenly, it’s inspectors, legal letters, and pissed-off tenants.
3. Tenants lose patience
They stop calling. They stop paying. Then they leave. And when they talk, your building’s name goes with them.
4. Building structure can get damaged
The water creeps where you can’t see. Into beams. Into walls.
And by the time you spot the sag or smell the rot, you’re in for the biggest repair bill of the year.
5. Insurance claims get denied
You waited. Now the insurer’s saying it’s ‘negligence.’ No pay out. No mercy. Just a full repair bill with your name on it.
6. Repairs triple in cost
Repair costs triple, because emergency fixes are always more expensive than proactive solutions.

What Are Box Gutters and How to Actually Fix Them
Box gutter waterproofing is a specialized job and most contractors get it wrong.
Over 90% of commercial and industrial buildings have box gutters built into the roofline.
When these clog or rust, water doesn't overflow, it floods inside, damaging ceilings, stock, equipment, and even halting operations.
Most “fixes” just patch the symptoms, not the real system.
That’s why we use our Waterproof Lab Gutter Wrap System, a proven, long-term solution that’s already sealed over 7.5km of guttering across South Africa, protecting buildings, tenants, and reputations from costly water damage.
