Siding and exterior upgrades in Washington

Choose siding and exterior materials

Siding work can replace an entire exterior or focus on selected elevations. Share the current material if known and keep safe photos ready for follow-up. Compare fiber cement, vinyl, wood, and other options by product, finish, profile, and included work.

A complete plan names the product, corners, trim, and elevations included. It covers removal, disposal, openings, penetrations, and connections to existing roof or masonry details. For partial replacement, identify transitions and materials that remain.

Plan each exterior finish

Painting calls for its own preparation and finish details: surfaces to scrape or repair, primer, coating system, colors, and finish coats. Keep it as a distinct project item alongside siding replacement.

For trim and fascia, identify affected runs, repair versus replacement, material and finish, and any roof-edge or drainage work outside the project. If several trades are involved, clarify which contractor covers each task. Also note doors, windows, vents, corner boards, and wall transitions in each elevation, plus the approximate area of each planned repair.

• Siding product, elevations, removal, and disposal.
• Painting preparation, primer, finish, and colors.
• Trim or fascia locations and repair or replacement.
• Moisture barrier or hidden-condition work to be scoped.

Allow for hidden repairs

Rot behind old siding may only become visible after removal. Set a process for documenting, measuring, pricing, and approving newly exposed work before it begins. State whether moisture barrier installation is included or separate.

List wall repair, barrier work, siding, trim, paint, and cleanup separately. You can then compare the finished work with the project plan and see when a specialist is needed.

Plan the exterior project

For an exterior upgrade, share the city, elevations or surfaces, work needed, known material, color preferences, and prior water or rot repair. This gives the project review a clear outline.

Check the contractor record through Washington L&I and compare materials, preparation, hidden conditions, cleanup, change approvals, and terms. Keep siding, painting, trim, and barrier work distinct in each proposal.
