Yellowing corners or watermark on your walls are a sign that you should call Nano-G’s Inspection team to help assess your premise and get waterproofing done.
Homes, offices, and businesses are prone to hidden waterproofing issues that seem to come out of nowhere- a faint watermark can turn into an ugly, unsightly hole in a matter of weeks if left unchecked. It’s definitely a shame to have if you’re expecting guests!

Catch that stain before it becomes a leak! Nano-G’s inspection team comes with a thermal scanner to detect any water damage that has occurred, for FREE!
Unfortunately, an unsightly yellow patch in your ceiling is already a sign that action must be taken before your stain becomes a hole, or worse- MOULD. If you start seeing any black spots, it’s a sign that germs, fungus, or algae have been building up for a long period of time.
You’ll have to act fast – these colonies can spread to other areas of your premises, making waterproofing for watermark damage essential.

Of course, with all this organic matter growing on your surfaces, you should expect some pests to appear alongside damage to your walls and ceilings.
