What this video covers

Pin-less moisture meters provide a relative assessment of deck core condition rather than an absolute measurement of water content.▶ 3:56 To establish a baseline, take readings on several vertical surfaces, which typically shed water and remain dry.▶ 8:59 Scan the deck in a grid pattern at six-to-12-inch intervals, marking areas that deviate significantly from the established baseline.▶ 11:14 Large, contiguous high-reading patches suggest actual moisture intrusion, while narrow, isolated strips often indicate false positives from internal wiring or metal backing plates.▶ 12:11 Before initiating repairs, confirm high readings by extracting core samples through existing hardware bolt holes or by drilling a small, shallow test hole from the interior.▶ 13:08 Use a piece of tape on the drill bit as a depth stop to avoid penetrating the exterior skin.▶ 16:12 If the extracted shavings feel damp or smell, the core is compromised.▶ 14:45 Moisture meters are diagnostic aids that require visual confirmation to prevent unnecessary deck deconstruction.▶ 16:02
