Identify the supplied lumber.
Ask the supplier whether the actual pieces were incised before treatment. Keep their product and treatment identification with the deck material record.
Decks · Rochester, Washington
Decks in Rochester proposed with incised treated lumber should distinguish the treatment pattern from a damage finding. Regular small cuts can be part of preparing certain wood species for preservative penetration; they do not by themselves describe every split or defect in a delivered piece.
Ask the supplier to identify the actual lumber and treatment process, then have the responsible provider assess any separate condition concern. Keep the material specification and the decision about an affected piece connected to the deck component it will serve.

Deck building
The useful discussion starts with the supplied lumber record and the marks actually observed. An explanation of incising is neither permission to ignore damage nor a reason to remove material to make every treated surface look smooth.
Ask the supplier whether the actual pieces were incised before treatment. Keep their product and treatment identification with the deck material record.
Show the provider the specific piece and location if marks look irregular or another defect is suspected. Request an assessment of that component rather than extending a general explanation to every visible change.
Have the designer and installer confirm the specified lumber for its structural role and exposure. Record any rejected or substituted pieces and preserve the accepted material information.
Before work begins
Confirm the proposed platform, supports and related work with Thurston County. Its limited low-deck exemption does not establish lumber suitability or remove other applicable regulations.
This guide provides no grading decision, repair recipe or structural capacity for an incised member. Have the qualified provider assess the supplied material and applicable design.
Ask the supplier to identify the treatment process for the actual wood. Have any separate damage concern assessed for the particular piece and component.
Have the responsible professional confirm the material specification, condition and actual deck role. A treatment-process explanation is not a structural acceptance.
Discuss appearance and any proposed treatment with the supplier and installer before changing the supplied wood. Keep the material’s intended use and instructions in that decision.
Share the treated-lumber identification and the specific pieces or marks you want the supplier and deck provider to assess.
