Community Tips

TipKasa Team

Use a screwdriver to probe soft spots in deck boards and joists -- if the tool sinks more than 1/4 inch with light pressure, wood rot has compromised the structural integrity and that section requires replacement rather than surface repair. This five-second test prevents costly deck collapses by catching decay before it spreads to load-bearing components.

WarningKasa Team

Never assume a deck built before 2004 is pressure-treated safely; older treated lumber often contains arsenic-based compounds that leach into soil and pose health risks during sanding or cutting. If construction predates modern copper-based treatments, consult a local environmental agency before disturbing the wood, as specialized disposal may be required.

Cost InfoKasa Team

A thorough deck inspection using a moisture meter like the Extech MO55 ($35-50) identifies hidden water intrusion in seemingly sound boards, preventing expensive structural repairs that typically run $1,500-4,000 when rot reaches support beams. Early detection through moisture mapping costs under $50 in tools but saves tens of thousands in remediation. ---
