Trace the water path
Inspect roof-to-wall intersections, openings, penetrations, trim joints and ground clearance. Record where water could enter and how it should return outside. New cladding cannot correct an unresolved flashing defect.
A siding bid should explain why the exterior failed and how the complete wall will drain and dry after work. For a Yacolt property, document elevations, openings, penetrations, trim, access and concealed-condition rules, then compare proposals that specify the same removal limits, water-management layers and finish result.
Require measured elevations, cause findings, removal limits, substrate repair rules, weather-resistive barrier and flashing details, window and door interfaces, clearances, trim, finish, temporary weather protection, permit responsibility and concealed-layer photographs.
Inspect roof-to-wall intersections, openings, penetrations, trim joints and ground clearance. Record where water could enter and how it should return outside. New cladding cannot correct an unresolved flashing defect.
List wall area, corners, windows, doors, meters, vents, decks and roof lines. Note access and landscaping. One elevation schedule prevents contractors from assuming different difficult transitions.
Describe removal, sheathing investigation, weather-resistive barrier, flashing transitions, fasteners and cladding. Require progress photographs before coverage. A product name is not an installation detail.
State how windows, doors, vents, hose bibs, lights and meters are removed, flashed or worked around. Assign regulated trades and restoration. These joints need one responsibility plan.
Define how concealed deterioration is measured, photographed and approved. Use rates where practical and structural review when load-bearing members or connections are involved.
Evaluate exposure, clearances, fastening, profiles, finish, maintenance and warranty conditions. Record manufacturer instructions, approved color and sample details.
Qualifying pre-1978 painted-surface disturbance may require EPA RRP controls. Confirm age and scope before demolition and include containment, cleanup and records.
Define staging, pedestrian access, plant protection, debris, temporary weatherproofing and daily closure. Name who responds if weather changes while a wall is open.
Plan wall areas so exposed sheathing and water-management layers can be inspected and protected before the crew advances. Coordinate windows, meters, vents and finish trades. The schedule should identify which evidence releases cladding installation rather than relying only on a promised date.
If removal reveals rot, damaged framing or incompatible prior work, require photographs, measured extent, proposed repair, price and schedule effect before permanent added work. A unit rate helps only when the actual quantity and acceptance standard are documented.
Inspect flashings, approved sealant locations, clearances, fasteners, penetrations, finish and cleanup. Keep product information, warranties, permits, inspections, changes and concealed-work photographs.

EPA RRP addresses qualifying painted-surface disturbance in pre-1978 housing.
| Observed condition | Next evidence | Contract boundary |
|---|---|---|
| Isolated damaged area | Open enough to confirm cause | Exact patch and match standard |
| Repeated failure on one elevation | Measure openings and interfaces | Elevation replacement |
| Broad cladding or barrier failure | Document all walls and transitions | Complete system scope |
| Cause remains uncertain | Targeted investigation | Findings before final price |
Separate investigation, removal, disposal, sheathing, water-management layers, cladding, trim, openings, trades, access, protection, finish and closeout.
No. Diagnose entry and drainage paths so replacement addresses the cause.
Measured elevations plus openings, trim, penetrations, removal, layers, restoration and exclusions.
Use photographs, dimensions, defined rates and written approval.
It depends on structural changes and full scope; confirm with Clark County.
Compare installation, exposure, clearances, fastening, finish, maintenance and warranty.
Qualifying pre-1978 work may trigger EPA lead-safe renovation requirements.
Document sheathing, repairs, barrier laps, flashing, openings and penetrations.
Keep products, warranties, permits, inspections, changes, photographs and punch list.
Share elevation photographs, leak history, known materials and finish goals.
