Crawl Space & Moisture Control
12 Mil White Encapsulation
Our heavy-duty 12 mil white vapor barrier encapsulation fully seals your crawl space, creating a clean, dry, and energy-efficient environment beneath your home. This premium barrier blocks ground moisture, discourages mold growth, deters pests, and dramatically improves the air quality throughout your living space — while making your crawl space easy to inspect and maintain.
Vapor Barrier Installation
Moisture infiltration is one of the leading causes of structural damage and indoor air quality issues in Pacific Northwest homes. Our professional vapor barrier installation creates a continuous, sealed moisture shield across your crawl space floor and walls — protecting your subfloor, joists, and insulation from humidity, condensation, and ground water for years to come.
Sub Floor Seal
A properly sealed subfloor keeps cold air, moisture, and unwanted pests from migrating into your living space. Our subfloor sealing service closes gaps, cracks, and penetrations in the floor assembly, improving thermal performance and reducing energy loss — particularly effective in homes with unconditioned crawl spaces.
Sump Pump Installation
Standing water in your crawl space or basement is a serious threat to your home’s structural integrity. We install high-quality sump pump systems designed to automatically collect and discharge groundwater before it causes damage. Our installations include proper pit placement, float switches, and discharge routing to keep your home dry year-round — critical in the wet Pacific Northwest climate.
Water Extraction
When flooding or water intrusion strikes your crawl space, basement, or interior space, fast action is critical. Our water extraction team responds promptly to remove standing water using commercial-grade equipment, minimizing damage to insulation, flooring, and structural wood. We also identify and address the source of water entry to prevent recurrence.
Access Door Creation
Safe, convenient crawl space and attic access is essential for maintenance, inspections, and utility work. We install properly framed and sealed access doors that provide easy entry without compromising your home’s thermal envelope or pest barrier. Whether you need a new opening cut or an existing hatch upgraded, we ensure the access point is structurally sound, weathertight, and professionally finished.
Mold, Health & Sanitation
Mold Remediation
Mold in your crawl space, attic, or walls is more than an aesthetic problem — it’s a health hazard and a structural threat. Our certified mold remediation team safely identifies, contains, and removes mold colonies using industry-standard protocols. We treat affected wood surfaces, eliminate contaminated materials, and address the underlying moisture issue to stop mold from returning.
Mold Remediation Install
After mold has been removed, long-term prevention requires the right protective treatments in place. We apply EPA-registered antimicrobial coatings and encapsulants to treated surfaces, install vapor control layers, and improve ventilation where needed — creating conditions that are inhospitable to future mold growth and protecting your home’s air quality for the long haul.
Sanitation & Decontamination Service
Rodent infestations and biological contaminants in crawl spaces and attics leave behind hazardous droppings, urine, nesting materials, and pathogens. Our full sanitation and decontamination service safely removes all contaminated insulation and debris, disinfects affected surfaces with hospital-grade treatments, and eliminates odors — returning your home to a safe, clean condition before re-insulation.
Home Exclusion
Rodents and pests don’t just destroy insulation — they create fire hazards, spread disease, and compromise your home’s structural integrity. Our home exclusion service locates and permanently seals every potential entry point including foundation vents, pipe penetrations, utility openings, and gaps in the building envelope — preventing future infestations without the use of harmful chemicals.
Air Quality & Duct Services
Air Duct Replacements
Old, deteriorated, or improperly installed ductwork is one of the biggest sources of energy waste in homes. We completely remove and replace damaged flex duct or rigid duct systems, ensuring proper sizing, insulation, and sealing throughout. New ductwork improves HVAC efficiency, eliminates hot and cold spots, reduces energy bills, and delivers cleaner air to every room in your home.
Air Duct Sealing
Leaky ducts can waste 20–30% of your conditioned air before it ever reaches a living space. Our professional duct sealing service uses mastic sealant and approved tapes to close every joint, seam, and connection in your duct system — dramatically improving HVAC efficiency, lowering utility bills, and removing pathways for unconditioned air, allergens, and contaminants to enter your airstream.
Dryer Duct Repair & Reroute
A clogged, disconnected, or improperly routed dryer duct is a leading cause of house fires. We inspect, repair, and professionally reroute dryer exhaust systems using rigid metal ductwork — improving airflow, reducing drying time, eliminating lint buildup hazards, and ensuring your dryer vents safely to the exterior. Code-compliant installations for new and existing homes.
Duct Replacements
When your duct system is beyond repair — due to age, rodent damage, mold contamination, or collapsed sections — complete duct replacement is the most cost-effective long-term solution. Our team designs and installs a new duct layout optimized for your home’s floor plan, HVAC system, and airflow requirements, delivering balanced comfort and maximum efficiency throughout every room.
Roof Vent Replacement
Proper attic ventilation is essential for preventing moisture buildup, ice dams, and premature roof deterioration. We replace damaged, obstructed, or undersized roof vents to restore the natural airflow your attic needs. Adequate roof ventilation extends shingle life, reduces summer cooling loads, and prevents the condensation that leads to mold and structural wood rot.
Waterproofing & Structural
Waterproofing
Water infiltration into your foundation, crawl space, or basement causes rot, mold, structural settling, and long-term property damage. Our comprehensive waterproofing solutions include interior and exterior drainage systems, membrane applications, crack injection, and sump pump integration — creating a multi-layer defense that keeps your home dry regardless of soil conditions or rainfall levels.
Basement WMP Finish
Our Waterproof Membrane Protection (WMP) finish system is a specialized basement treatment that applies a seamless, waterproof coating directly to concrete walls and floors — sealing pores and hairline cracks that allow moisture seepage. This finish dramatically reduces humidity in your basement, prevents efflorescence, and creates a clean, finished surface suitable for storage, living space, or future renovation.
Insulation Services
