How do I know if my deck needs professional structural work?

If you find soft or punky wood when you probe the main beams or posts with a screwdriver, or if the deck feels unstable or bouncy in ways that boards alone wouldn't explain, you may need a licensed contractor to assess it. A good local pro will tell you honestly when something is above handyman scope.

Can you match my existing deck board material?

Local pros typically stock common pressure-treated lumber. For composite decking (Trex, TimberTech, etc.), share the brand and color so matching material can be sourced before the appointment.

Do you apply stain or sealant after repairs?

Yes — repaired areas can be sanded, cleaned, and finished with a penetrating deck stain or sealant. For full deck refinishing, combining that with the repair visit saves a trip.

When You Need a Licensed Contractor Instead

If the deck's primary structural members — ledger board, beams, or main posts — show significant rot or the deck requires a building permit (most decks over 30" above grade do), a licensed contractor should evaluate and repair it. Handyman scope covers surface-level board and railing repair, not structural reconstruction.
