Assess the frame first.
Have the qualified provider identify framing that can remain and material needing repair. Tape should not conceal an unresolved condition in the proposal.
Decks · Milton, Washington
Decks in Milton can include protective tape on framing beneath the boards. Ask what the proposed product protects and where it will be applied before treating it as either a structural repair or a waterproof ceiling for the space below.
Evergreen Home Pro helps you compare the finished deck surface with the work on the frame underneath. Put any framing replacement and moisture-protection products on separate scope lines.

Deck building
Trex Protect describes its joist and beam tape as flashing intended to shield those framing surfaces from moisture. That product purpose does not establish that an existing frame is sound or that rain cannot pass between deck boards.
Have the qualified provider identify framing that can remain and material needing repair. Tape should not conceal an unresolved condition in the proposal.
Ask which joist, beam or other surfaces receive the specified product and how that fits the selected decking system.
If a dry area is part of the project goal, request a designed drainage scope. Do not infer it from a line item for joist tape.
Before work begins
Milton’s deck FAQ identifies height above grade as a permit consideration. Ask the Building Division to confirm the complete proposal, including attachment, alterations and any other work, rather than deciding from the decking finish alone.
Keep the frame assessment, replacement footprint and any under-deck drainage on the drawings that describe the actual construction.
Have the frame assessed and any required repair specified separately.
A dry-space goal needs its own drainage design; framing tape alone does not describe that system.
Yes. Distinguishing the existing-frame work from the protective product makes the proposed construction clearer.
Share the deck’s condition and intended use, including whether you want a usable dry space below.
