Back to Dry Restoration has treated mold in Puyallup homes since 2011, when Alicia Brennan founded the company after years as a claims adjuster watching homeowners lose coverage fights over documentation gaps. The South Hill and Waller areas, with their older post-war foundations and clay-heavy soils that wick moisture, keep us busy every spring and fall. We’ve restored more than 12,000 homes since then, and every single job started with a written price and ended with a documented photo record. Our technicians are background-checked, uniformed, and arrive with license numbers visible - not subcontractors, not day laborers.

Puyallup’s location at the foot of Mount Rainier creates a specific mold pressure: the Puyallup River valley traps cool, moist air against the Cascades, and homes in the valley floor neighborhoods like North Puyallup and downtown see relative humidity spikes that climb above 60 percent for weeks at a stretch. That moisture, combined with the tight building envelopes common in homes built between 2015 and 2025, creates exactly the stagnant conditions where Aspergillus, Penicillium, and Stachybotrys colonize drywall and OSB sheathing. We’ve documented this pattern in hundreds of Puyallup jobs. We know where to look, what to measure, and how to prove to your insurer that the work was necessary and complete.

What Our Mold Remediation Service Includes

Mold Inspection & Testing

A proper Mold Inspection & Testing in Puyallup starts with moisture mapping, not guesswork. We use thermal imaging cameras and calibrated moisture meters to identify elevated readings in wall cavities, subfloors, and crawl spaces - the places where Puyallup’s seasonal humidity hides colonization before it becomes visible. When air sampling is appropriate, we collect spore trap samples following IICRC protocols and send them to an independent laboratory for speciation; we do not perform our own testing to avoid the conflict of interest that voids results in claims disputes. You’ll receive the lab report, the moisture readings by room, and our written findings before we propose any remediation scope.

Mold Removal

Mold Removal is the physical extraction of colonized materials and the HEPA vacuuming of spore-contaminated surfaces, performed under negative air pressure containment to protect unaffected areas of your Puyallup home. We remove only what must be removed - drywall that has delaminated, insulation that has compacted, structural members with more than 10 square feet of visible colonization - and we document each removal decision with a photo and a moisture reading. Our crews use sealed disposal bags and decontamination chambers at containment egress points; every bag is weighed and logged. This documentation becomes part of your file, and your adjuster receives it directly if a claim is open.

Black Mold Remediation

Black mold, most commonly Stachybotrys chartarum, thrives in Puyallup homes where water intrusion has gone unaddressed for 72 hours or more - we see it frequently in Bonney Lake and Orting properties with failed crawl space vapor barriers, and in Puyallup’s 1980s-era split-levels with basement walkouts that trap groundwater. Black mold remediation requires full respiratory protection for technicians, double-layer containment with air scrubbers running at 6 air changes per hour, and the removal of all cellulose-based materials in the affected zone. We do not attempt to “treat” black mold in place with sprays or ozone; the RIA and IFA protocols we follow require physical removal of the growth matrix, and our documentation reflects that standard.

Air Quality Restoration

After physical removal, airborne spore counts in Puyallup homes often remain elevated above outdoor baseline levels until the HVAC system and ductwork are addressed. Our air quality restoration service includes HEPA filtration during remediation, followed by duct inspection with remote camera systems and, when indicated, mechanical cleaning to NADCA standards. We take post-remediation air samples from the same locations as our pre-remediation samples, and we do not declare the job complete until the lab confirms spore counts have returned to outdoor equivalence or below. You receive both lab reports, dated and labeled by room, as part of your final documentation package.

Crawl Space Treatment

Crawl spaces in Puyallup’s South Hill and Summit neighborhoods are our most frequent mold remediation sites - the combination of clay soil, seasonal groundwater rise, and vented crawl space designs that pull humid summer air across cool joist surfaces creates chronic condensation. Our crawl space treatment begins with a full moisture survey: we measure wood moisture content with pin-type meters at 16-inch intervals along joists and subflooring, and we record vapor pressure differential between the crawl space and the conditioned living space above. Treatment includes removal of contaminated insulation, HEPA cleaning of all surfaces, and installation of temporary or permanent dehumidification depending on the source moisture diagnosis. We photograph every joist bay before and after.

Moisture & Humidity Control

Remediation without moisture control is temporary, and we see the callbacks to prove it. Our moisture and humidity control service identifies the source - failed flashing, foundation cracks, inadequate bathroom exhaust, or the groundwater intrusion common in Puyallup’s valley neighborhoods - and specifies the repair or equipment needed to maintain relative humidity below 60 percent year-round. We deploy Dri-Eaz and Phoenix dehumidifiers during active drying, and we specify permanent solutions from the same manufacturers when the source is ambient humidity rather than an acute leak. Every recommendation is written, priced, and signed off before installation begins; Haven Standard, Clause 1 applies to moisture control work exactly as it does to remediation.

Signs You Need Mold Remediation Right Now

• A persistent musty odor that intensifies in humid weather. In Puyallup, this often appears in May and June when the Puyallup River valley’s cool air meets warming interior surfaces, creating condensation in wall cavities. The smell indicates active microbial volatile organic compound (MVOC) production - meaning mold is metabolizing and releasing gases, not merely present. If you notice this pattern, the colony is established and growing; surface cleaning will not address growth inside the wall.
• Visible discoloration on drywall, especially near windows, exterior walls, or plumbing fixtures. Puyallup homes built between 2015 and 2025 often used paper-faced drywall that acts as a nutrient source for mold; even small water stains with accompanying speckling indicate that the paper facing has been compromised. The visible spot is typically the smallest expression of a larger colony behind the surface. We measure outward with moisture meters before cutting any inspection holes, and we document the full extent before proposing removal.
• Recent water damage that was dried without professional equipment or documentation. We see this frequently in Puyallup’s newer construction: a pipe leak or appliance overflow is mopped up, fans are run for a day or two, and six weeks later mold appears at the baseboards. Consumer-grade fans do not generate the airflow volume or the heat needed to drive moisture from subfloors and wall cavities; without psychrometric data showing progressive drying, you have no proof the structure was ever dry. Our remediation of these cases always includes removal of the improperly dried materials, because mold has colonized the residual moisture zone.
• Health symptoms that improve when you leave home and return indoors. Respiratory irritation, persistent cough, or sinus congestion that correlates with time spent in specific rooms - particularly bedrooms over crawl spaces or bathrooms with inadequate exhaust - can indicate elevated indoor spore counts. We do not diagnose health conditions; we measure the environment. If your symptoms have a location pattern, we recommend air sampling and moisture mapping to determine whether your Puyallup home’s indoor environment is the contributing factor.
• Sagging or stained ceiling tiles, particularly in single-story additions with flat roofs. Puyallup’s winter rain load and occasional snow accumulation stress flat roof drainage systems; when scuppers or internal drains clog, water pools above the ceiling plane and migrates laterally before visible dripping occurs. By the time a tile stains, the cavity above is typically saturated and mold has colonized the tile backing and any fiberglass insulation in contact with it. We inspect with borescopes when possible to minimize disruption, and we document the full water path for insurance purposes.

Our Mold Remediation Process - Step by Step

1. 1
   Containment and negative air pressure establishment. Before any removal begins, we seal the affected area with 6-mil polyethylene sheeting and install HEPA-filtered negative air machines to maintain inward airflow at containment boundaries. This prevents spore migration to clean areas of your Puyallup home. We photograph the containment setup, log the air machine flow rates, and verify pressure differential with a manometer - the documentation your adjuster expects to see.
2. 2
   Moisture mapping and material classification. Using thermal imaging, pin and pinless moisture meters, and hygrometers, we identify all wet or previously wet materials within the containment zone. Each reading is logged by location, material type, and percentage moisture content relative to dry standard. Materials are classified as salvageable, cleanable in place, or requiring removal based on IICRC S520 standards. You receive this map before we proceed.
3. 3
   Controlled demolition and HEPA cleaning. We remove non-salvageable materials with minimal dust generation, using sealed bags and decontamination chambers at all egress points. Remaining structural materials are HEPA vacuumed and wet-cleaned with antimicrobial solutions appropriate to the surface. Every bag is weighed, every surface is photographed before and after cleaning, and the HEPA vacuum filter is logged by serial number for chain-of-custody documentation.
4. 4
   Drying and dehumidification with psychrometric monitoring. If the moisture source is active or residual humidity remains elevated, we deploy Dri-Eaz and Phoenix dehumidifiers with air movers to achieve and maintain drying goals. Daily readings of temperature, relative humidity, and specific humidity are recorded on psychrometric charts; this data proves progressive drying and supports insurance coverage for the drying phase. We do not guess at dryness - we measure it.
5. 5
   Post-remediation verification and documentation delivery. After cleaning and drying, we conduct a visual inspection, repeat moisture readings at original measurement points, and collect air samples for laboratory analysis. The job is not complete until the lab confirms spore counts at or below outdoor baseline, moisture readings meet dry standard, and all documentation - photo record, drying log, written scope, and lab report - is assembled in your file. Your 365-Day Done Right Promise under The Haven Standard is activated at this point, in writing, with Alicia Brennan’s signature.
