Low decks, they look great right?
BUT do they have adequate termite protection where they abut the house?? If not, this situation may allow concealed termite attack.
Many decks cover the physical termite barriers, exposed slab edges & brick weep holes.
Ensure you either:
Leave a visual gap between the deck & building/slab edge.
Or install a physical termite barrier the abutting join eg. Kordon, Termseal, Trithor to name a few.
