Independent Building Investigation & Diagnostics
Water Intrusion & Structural Inspections for Santa Cruz & Monterey County Homes
Independent, engineer-backed investigations for water damage, mold, foundation cracks, and construction defects across Santa Cruz and Monterey Counties.
Field investigation and documentation — not a repair sales call.
Which of these sounds like your building?
Water is entering the building and you don’t know where from
Unexplained moisture, staining, or musty odor
A leak keeps returning after repair
Suspected hidden damage behind finishes
A roof or waterproofing system appears to be failing
Cracks or other structural concerns
A previous repair didn’t solve the problem
Disagreement about what caused the damage
Core investigation services
Each service addresses a distinct category of building problem — not a generic inspection checklist.
01
Water Intrusion Investigation
Locating the actual entry point and path of water into a building, not just the wet spot.
02
Water Damage & Moisture Investigation
Documenting the extent of water damage and ongoing moisture conditions inside a structure.
03
Building Envelope Investigation
Evaluating roofs, cladding, windows, and doors as a connected system.
04
Roof & Waterproofing Investigation
Determining why a roof or waterproofing assembly is no longer performing.
05
Structural Investigation
Assessing cracking, movement, or damage to framing, foundations, and load-bearing elements.
06
Construction Defect Investigation
Identifying design or construction issues behind recurring building problems.
07
Failure Analysis
Determining why a material, assembly, or system failed before its expected service life.
08
Forensic Investigation & Documentation
Field investigation and technical documentation to support disputes, claims, or litigation.
How an investigation works
01
Initial Consultation
We discuss what you’re seeing, when it started, and what you need from an investigation.
02
Budget Approval
We provide a proposed budget for the investigation scope before any site work begins, for your review and approval.
03
Site Investigation
On-site inspection of the affected area and related building assemblies.
04
Testing & Documentation
Moisture readings, thermal imaging, and other field methods as appropriate, with photo documentation.
05
Analysis
Findings are reviewed against how the building assembly is supposed to perform.
06
Findings & Recommendations
A clear explanation of what’s happening, why, and what to do next.
07
Report / Expert Support
Written report, and expert consultation or documentation support when a dispute or claim is involved.
A stain is a symptom. It isn’t the cause.
Water staining, peeling paint, or a musty smell tells you something is wrong — it doesn’t tell you why. The source could be roofing, flashing, windows, wall assemblies, drainage, waterproofing, plumbing, condensation, or a combination of several. Repairing the visible symptom without identifying the source is why so many leaks come back. An investigation exists to find the actual cause before anyone touches a repair.
Field methods, not guesses
- Infrared thermography
- Moisture measurement (meters, T-RH probes)
- Ground-penetrating radar (GPR) where applicable
- Borescope and visual assembly investigation
- Material sampling and testing
- Decay and fungal growth assessment
- Drainage and slope evaluation
- Photographic and written documentation
