Attic Crawlspace Cleanup and Remediation in Orange County, CA
Attics and crawlspaces are the hidden engines of indoor air quality. When roof leaks, bathroom fan ducts, or ground moisture linger, mold can colonize roof sheathing, joists, or subfloor—and migrate into living areas. White Glove Plumbing & Restoration delivers disciplined attic/crawlspace mold remediation with hard containment, negative air, selective removal/cleaning, structural drying, and prevention fixes that actually last.
✓ True containment: Sealed access, decon area, pressure control
✓ HEPA + negative air: Capture spores at the source
✓ Root-cause repair: Leaks/venting/drainage corrected first
✓ Proof of results: Moisture targets and photo logs

What Is Attic/Crawlspace Mold Remediation?
A control-first program that isolates the attic or crawlspace with sealed containment and negative air, removes non-restorable materials (where required), and HEPA-cleans and decontaminates structural members (sheathing, rafters, joists, subfloor).
We then dry to target, correct the moisture driver (venting, drainage, air sealing), and verify results. Where requested or required, we coordinate third-party clearance testing.
Why Choose White Glove Plumbing
Plumbing + restoration, together: We fix the cause (roof/pipe/condensate/ground water) and perform remediation + dry-down—no hand-offs.
Standards-aligned: Hard containment, negative pressure with manometer checks, HEPA filtration, source removal, and dry verification—aligned with recognized remediation principles.
Built for tight spaces: Lift-certified and confined-space–trained techs; safe access, lighting, and ventilation solutions for attics and crawlspaces.
Carrier & assessor ready: Photos, moisture/psychrometric logs, pressure logs, and a clear scope that speeds approvals.
Immediate Actions (What to Do Now)
Don’t spray bleach. It can set stains and does not solve moisture.
Avoid disturbing growth. Keep access doors closed until contained.
Note likely sources: Roof leak, bath fan duct, attic AC condensate, crawlspace groundwater, missing vapor barrier.
If active water is present, shut it off or cover roof openings with a temporary tarp.
Call our 24/7 dispatcher. We’ll assess, contain, and start a safe remediation plan.
Common Situations We Handle
Attic: Roof/flashing leaks; bathroom fans vented into the attic; disconnected flex ducts; AC condensate spills; inadequate ventilation; missing air sealing at can lights/top plates.
Crawlspace: No vapor barrier; poor grading/drainage; leaking supply/softener/condensate; foundation vents pulling humid air; uninsulated cold water lines condensing; failed sump or no sump at all.
Hybrid: Stack effect pulling crawlspace air upward, spreading musty odors through living areas.
Assessment, Mapping & Plan
Thermal imaging and meters define wet assemblies; identify sources (roof/condensate/groundwater/duct leaks); set containment boundaries and drying targets.
Source Control & Containment
Temporary tarping/roof patch, fix active plumbing/condensate issues; build hard containment at the access hatch with zip doors and a decon zone; establish negative pressure with HEPA filtration and pressure monitoring.
Selective Removal (As Needed)
In crawlspaces: remove grossly contaminated insulation/vapor barrier sections. In attics: remove ruined insulation where required. Bag and eject through controlled routes to prevent cross-contamination.
HEPA Cleaning & Surface Decontamination
HEPA vacuum structural surfaces; mechanical prep of stained wood (wire brush/scrape; media blasting such as soda or dry ice where appropriate); damp-wipe with compatible cleaners; follow with a second HEPA pass (the “HEPA sandwich”).
Structural Drying & Conditioning
Chambered drying using LGR dehumidifiers, ducted air movers, and airflow controls; daily RH/GPP and material moisture logs until targets are met (e.g., wood returning toward local baseline).
Prevention & Verification
Install/repair vapor barrier (crawlspace), improve venting/air sealing (attic), correct bath fan ducting to exterior, recommend sump/dehumidifier if needed; provide final photos, moisture readings, and re-entry guidance; coordinate optional third-party clearance.
What’s Included
Moisture survey & plan (boundaries, targets, source notes)
Hard containment & negative air with pressure monitoring and decon zone
Selective removal/disposal (contaminated insulation/vapor barrier)
HEPA vacuum + mechanical prep + damp-wipe (with second HEPA pass)
Chambered drying with daily moisture/psychrometric logs
Prevention upgrades (vapor barrier/venting/air-sealing recommendations) and a documentation packet
Costs & Timelines (What to Expect)
Typical duration: Small attic/crawlspace projects stabilize in 2–4 days (including dry-down); larger footprints or heavy media-prep may extend timelines.
Cost drivers: Square footage/clearance height, demo/insulation replacement, chamber complexity, media blasting need, equipment days, and access (tight hatches, low crawl).
Transparent scope: A line-item estimate before work begins; progress photos and logs shared with you (and your adjuster, if applicable).
Insurance & Claims Help
Coverage varies. We document cause (roof leak, condensate, plumbing) separately from remediation/dry-down.
Carrier-friendly files: Photos, zone sketches, negative air/HEPA run logs, moisture/psychrometric logs, and clear scope notes.
Supplements: If hidden damage appears (e.g., under insulation or behind sheathing), we document and submit updates promptly.
On older homes or where disturbance of suspect materials is likely, we coordinate pre-disturbance asbestos/lead testing per local requirements.
Risks of Waiting (Why Act Now)
Spread to living areas via stack effect and return air paths.
Wood decay and odor binding as moisture persists.
Higher rebuild costs from expanded demo/insulation replacement.
Pest and corrosion issues in damp crawlspaces and attics.
Methods, Equipment & Quality Standards
Containment & pressure: Framed poly barriers at access, zip doors, manometer/differential pressure checks, and HEPA negative air sized to volume.
Cleaning sequence: HEPA vacuum → mechanical prep (brush/scrape/media) → damp-wipe → HEPA vacuum; filter changes tracked in the log.
Drying targets: Chambers typically <50% RH steady-state; wood trending back to local baseline (often 12–16% MC, species/conditions dependent).
Prevention details:
Attic: Vent bath fans to exterior, repair roof/flashing, air-seal top plates/penetrations, confirm balanced intake/exhaust ventilation.
Crawlspace: Install 6–10 mil vapor barrier (taped/sealed at piers/walls), improve grading/drainage, add sump/dehumidifier as indicated, insulate cold lines to reduce condensation.
Safety & compliance: Confined-space awareness, PPE, lighting, and safe egress; coordinate testing where required; compliant waste handling and clean load-out routes.
Verification: Visual cleanliness, odor check, and documented moisture readings; optional third-party clearance available.
Frequently Asked Questions
Can we just paint or “seal” the wood?
Not before cleaning and drying. Encapsulation is selective and only after surfaces are clean and at moisture target.
Do you always remove insulation?
Only when it’s wet, contaminated, or blocks proper cleaning/drying. We replace what’s removed to spec.
Is media blasting required?
Not always. We reserve soda/dry-ice blasting for stubborn staining/porosity after standard prep.
Do we need a vapor barrier in the crawlspace?
Yes—properly installed 6–10 mil barrier is critical for long-term moisture control.
Will my home smell musty afterward?
Correct remediation and prevention steps eliminate the source. We verify with odor checks and moisture readings.
Do you handle roof/venting/drainage fixes?
Yes—source repair is part of our end-to-end approach, or we coordinate trusted trades where needed.
