Mold stain removal & Remediation

Two Set Procedure 

Step 1: RMR-86 (The "Instant" Stain Remover)
This is a powerful sodium hypochlorite-based formula designed to eliminate mold stains on contact.

Action: It penetrates deep into the wood fibers (rafters, floor joists, or sheathing) to dissolve the mold body and lift the dark staining.

Result: Within minutes, the wood looks "like new" again. It is incredibly effective for visual restoration, but it doesn't provide a long-term defense on its own.

Disinfectant and Clean

Step 2: RMR-141 (The Fungicide & Disinfectant)

Once the stains are gone and the surface is dry, you must apply the "defense" layer. RMR-141 is an EPA-registered fungicide/virucide.

Action: This is an "encapsulant-lite" or residual treatment. It kills any remaining spores at the root level and leaves a fungistatic coating on the surface.

Result: It inhibits the growth of mold, mildew, and odors. It creates a chemical environment where mold simply cannot survive, even if moisture levels spike temporarily.

​ATTIC CLEAN OUTS

We believe that a truly healthy home begins with a clean slate. Our Full Attic Clean-Out Service is designed for homeowners seeking to eliminate years of accumulated dust, allergens, and the hazardous remains of past pest infestations. We meticulously remove every bit of contaminated material down to the drywall and joists, ensuring a 100% fresh start. This critical process allows our team to perform a high-definition structural inspection, identifying hidden air leaks/Issues.


SUBFLOOR SEAL

Providing a specialized sub-floor sealing service designed to eliminate the "stack effect" that allows cold, damp air from your crawlspace/Attic into your living areas. We identify and seal every structural penetration—including plumbing stacks, electrical wire runs, and sub-floor seams—using high-performance, expanding foam and industrial-grade sealants. By creating an airtight thermal break between your home’s foundation and your flooring, we stop the drafts that cause cold floors and forced-air systems to overwork.


Fiberglass/Cellulose Blow In 

Proper attic insulation is the most effective way to regulate your home’s temperature and lower utility costs. We specialize in high-performance attic retrofits that meet or exceed the current Washington State Energy Code (WSEC) requirements. For our specific Marine Climate Zone, the state mandate typically requires a minimum thermal resistance of R-49, though we frequently recommend upgrading to R-60 for maximum efficiency and long-term savings.

12 Mil Encapsulation

At Premium NW Contractors LLC, we provide a comprehensive, high-performance approach to home health that transforms your crawlspace into clean, conditioned, and secure environments. Our signature Premium 12 Mil White Encapsulation system utilizes a heavy-duty antimicrobial liner with all seams and penetrations meticulously sealed with industrial-grade waterproof tape, creating a continuous barrier against soil gases and moisture. To actively manage humidity and prevent wood-decaying mold, we integrate professional-grade dehumidifiers for every install!

Weather Proof Access Covers

Experts specializing in the custom fabrication of Long lasting, weatherproof crawlspace covers designed to withstand the relentless moisture of the Pacific Northwest. Standard wood or ill-fitting vent covers are often the primary entry point for rot-inducing humidity and opportunistic rodents. We replace these compromised barriers with precision-engineered access systems built from premium, non-corrosive materials that will never warp, rot, or degrade.

Why's that smell coming from?

If you are noticing persistent, musty, or foul odors inside your living space, the source is often an unhealthy environment beneath your feet.Our expert team provides a comprehensive solution by first identifying the root cause—whether it’s wood-decaying mold, animal intrusion, damaged air system or standing water. We find and eliminate the source of the bacteria smell, ensuring the air circulating through your home is fresh and safe for your family.

Secure Access Doors

A precision-fitted crawlspace access door is the most critical barrier in protecting your home’s sub-structure from the elements and local wildlife. 

Our expert contractors replace rotted, ill-fitting wood hatches with custom-built access systems engineered from premium, weather-resistant materials designed to withstand the Pacific Northwest climate. Standard doors often warp or gap over time, creating an open invitation for rodents and moisture to infiltrate your home.

Dryer duct disconnected?

A disconnected or damaged dryer duct is more than just a ventilation issue—it is a significant fire hazard and a threat to your home’s air quality. When a duct becomes detached, highly flammable lint escapes and accumulates rapidly in confined areas like your crawl space or attic. This buildup acts as kindling, where a single spark or excessive heat from the dryer can ignite a fire that spreads undetected behind your walls. At Premium NW Contractors LLC, we specialize in identifying these separations and installing secure, code-compliant venting systems. By restoring proper airflow and removing combustible debris, we eliminate the primary cause of dryer-related house fires and ensure your home remains safe and efficient.

Home Exclusion!

Effective rodent control starts with a permanent structural solution. Our comprehensive home exclusion service goes beyond simple trapping; we identify and seal every potential entry point—from foundation gaps to attic vents—using durable, professional-grade materials that rodents cannot breach. By focusing on precision sub-floor sealing and reinforced vent covers, we eliminate the highway system pests use to enter your living space.
