Emergency Water Intrusion Inspection in Seattle & the Puget Sound Region
When water is getting inside a home or building and the source isn’t clear, the most important first step is a professional water intrusion inspection. Guessing or patching symptoms often leads to repeat leaks and more extensive damage.
Synapse Construction provides emergency water intrusion inspections throughout Seattle, the Eastside, and the greater Puget Sound area, with a focus on identifying how water is entering the building envelope and what it will take to stop it.
What’s Happening
Water intrusion problems don’t always show up where the failure occurs. Water can travel behind siding, windows, decks, and roof transitions before becoming visible inside.
We’re often called when:
- Water appears inside walls or ceilings during storms
- Leaks return after prior repairs
- Moisture or staining is discovered during an inspection
- There are signs of rot, mold, or musty odors
- Exterior details “don’t look right,” but the cause is unclear
In many cases, multiple systems interact — siding, flashing, windows, roofing, and waterproofing — making investigation critical.
Why a Water Intrusion Inspection Is Urgent
Unchecked water intrusion can cause significant hidden damage, especially in the Pacific Northwest climate.
Delaying investigation can lead to:
- Concealed rot within wall or floor assemblies
- Mold growth and indoor air quality concerns
- Structural deterioration
- Failed real estate, HOA, or contractor inspections
- Increased scope and cost of future repairs
Early diagnosis allows for targeted repairs instead of large-scale replacement.
How Synapse Construction Performs Water Intrusion Inspections
Our inspections are focused on understanding the path water is taking, not just where it shows up.
A typical water intrusion inspection may include:
- Exterior evaluation of siding, flashing, roof transitions, decks, and penetrations
- Identification of missing or failed flashing and waterproofing layers
- Selective removal of exterior materials when necessary to confirm conditions
- Documentation of findings with photos
- Clear explanation of recommended repair options
We approach inspections from a building envelope perspective, which allows us to connect symptoms to root causes.
Common Issues Identified During Inspections
During emergency water intrusion investigations, we frequently uncover:
- Missing or improperly installed flashing
- Failed weather-resistive barriers (WRB)
- Water dumping behind siding from roof or gutter details
- Improper window or door installations
- Failed deck membranes or waterproofing transitions
Many of these issues are concealed until an inspection is performed.
Photos & Investigation Examples
Water intrusion often occurs at complex window-to-roof transitions where original design details didn’t account for drainage and exposure.
