Storm / Rain Intrusion Mitigation
Wind-driven rain through roofs, windows, stucco, and doors? We stop the intrusion, protect interiors, and dry the structure — fast.

Why speed matters after wind-driven rain
Rain intrusion travels behind finishes and into cavities. Delays cause swelling MDF/trim, damaged insulation, electrical hazards, and microbial growth. We secure the opening, protect interiors, and start controlled drying immediately to reduce repairs and costs.
- Stops ongoing intrusion and interior damage
- Limits odors & microbial risk
- Shortens repair timelines & speeds insurance processing
Common rain intrusion pathways
Roof & Flashing
Shingle loss, failed underlayment, vent/penetration leaks, compromised flashing.
Windows & Doors
Failed seals, poor caulking, sill pan issues, wind-driven rain around frames.
Stucco & Siding
Cracks, missing weep control, intersection failures at decks and balconies.
Balconies & Decks
Drain clogs, membrane breaches, threshold leaks into living spaces.
Gutters & Downspouts
Overflow pushing water behind fascia and into walls/soffits.
Chimneys & Parapets
Cap and counter-flashing failures, hairline cracks, compromised mortar.
Our storm / rain mitigation approach
- Safety & Assessment: Electrical checks; thermal imaging & moisture mapping to identify migration paths.
- Temporary Weatherproofing: Roof tarps, board-up, poly sheeting, or temporary caulking as appropriate.
- Interior Protection: Containment, floor protection, content moving/raising, and debris control.
- Extraction & Stabilization: Remove trapped water; pull saturated insulation where required.
- Structural Drying: LGR/desiccant dehumidification + air movers; daily psychrometric & moisture readings.
- Selective Removal: Only where materials are non-salvageable or contamination warrants.
- Verification & Documentation: Meet dry goals; deliver photos, logs, and a clear wrap-up for owners/insurers.
Temporary repairs & coordination
We handle
- Roof tarping / board-up to stop active intrusion
- Interior containment & floor protection
- Drying plans with daily monitoring
We coordinate
- Roofers, window/door contractors, and stucco/exterior specialists
- Insurance adjusters with clear photos and moisture logs
- Mold remediation if growth is discovered (testing via third-party IEPs)
What to do before we arrive (if safe)
- Move small items and electronics away from leak areas; cover valuables with plastic.
- Avoid switching lights on under wet ceilings; keep children and pets out of affected rooms.
- Place towels/buckets to capture drips; don’t poke ceiling bulges.
- If safe, clear clogged gutters/downspouts to redirect water away.
Insurance & documentation
- We provide photos, moisture maps, psychrometric logs, and equipment lists.
- Coverage depends on the cause (wind-driven rain vs. exterior flooding) and your policy terms.
- We can communicate directly with your adjuster to streamline approvals.

Storm / Rain Intrusion — Frequently Asked Questions
Is wind-driven rain covered by insurance?
It depends on the cause and policy terms. Wind-driven rain may be covered; exterior floodwater often is not. We document thoroughly and can speak with your adjuster.
Do you install roof tarps or board-up openings?
Yes. We perform temporary weatherproofing (tarping/board-up) to stop active intrusion and protect interiors before drying.
Do you need to remove wet drywall or insulation?
Only when materials are non-salvageable or when moisture is trapped in cavities. We use targeted openings and removal to reduce repair scope.
How long does structural drying take?
Simple intrusions can dry in 2–4 days; complex assemblies, heavy humidity, or multi-room losses can take longer. We monitor daily and adjust equipment.
What if mold is discovered?
We set proper containment and remediation steps. For sampling or post-remediation clearance, we coordinate with independent third-party IEPs.
Can you help with odors after rain intrusion?
Yes. Source removal, thorough drying, cleaning, and professional deodorization strategies reduce lingering odors. See Odor Control & Sanitizing.
