Complete Crawl Space Remediation And Encapsulation
From mold remediation and pest debris removal to vapor barrier installation, dehumidifier systems, and full lifetime-warranty encapsulation, every crawl space scenario handled across Connecticut, New York, and Massachusetts by IICRC S520 certified crews.
Crawl Space Mold Remediation
IICRC S520 certified removal of active mold from joists, subfloor, rim joists, and insulation. HEPA vacuuming, physical removal of affected porous material, and EPA-registered antimicrobial treatment on every framing surface before encapsulation begins.
IICRC S520 · Framing treated
Vapor Barrier Installation
12-mil reinforced white vapor barrier mechanically fastened to walls and seam-taped across the dirt floor. Continuous coverage from footing to footing prevents ground moisture migration that feeds mold, rot, and pest activity.
12-mil reinforced · Seam-sealed
Dehumidifier Systems
Properly sized commercial-grade dehumidifier with condensate pump installed and tuned to hold the crawl space below 55% relative humidity year-round. Paired with a humidistat and gravity or pumped drain for unattended operation.
Commercial grade · <55% RH held
Additional Crawl Space Services
Pest Debris And Insulation Removal
Rodent droppings, nesting material, contaminated fiberglass insulation, and old vapor sheeting are double-bagged and removed. Surfaces sanitized before new insulation or encapsulation materials are installed.
Foundation Moisture Correction
Active water intrusion at footings and block walls identified, sealed, and drained. French drains, interior perimeter channels, and exterior grading recommendations addressed before the space is closed.
Sump Pump And Drainage
Primary and battery-backup sump pumps installed in a sealed basin, tied to a perimeter drain channel. Discharge piped outside the foundation with a frost-resistant exit point per local code.
Structural Wood Rot Assessment
Joists, sills, and subfloor probed with a moisture meter and visual inspection. Scope report identifies surface rot that can be treated in place versus structural rot that requires sistered framing or replacement before encapsulation.
Rodent Exclusion And Sanitizing
All entry points sealed with copper mesh, hardware cloth, and expanding sealant. Affected surfaces sanitized with EPA-registered products. Bait and mechanical traps left in place for a 30-day verification window.
Full Encapsulation With Warranty
Floor, wall, and pillar continuous 12-mil white reinforced liner, sealed dehumidifier, and closed vent covers. Material lifetime warranty on the liner, clearance photos, and a warranty binder delivered to the homeowner on completion.

Why A Wet Crawl Space Damages The Whole House
Up to half of the air a home breathes starts in the crawl space. Moisture, mold spores, pest allergens, and odor ride that airflow into living space every day. Ignoring the crawl space is one of the most common drivers of indoor air quality complaints, sagging floors, and insurance claims across Connecticut, New York, and Massachusetts.
Stack Effect Pulls Crawl Air Upward
Up To 50% Of Indoor Air
Warm air rises through the house and pulls replacement air from the crawl space. Whatever is below, mold spores, rodent waste, VOCs, and moisture, becomes part of the breathing environment on the main floor. Sealing the crawl space is an indoor air quality decision, not just a structural one.
Persistent Moisture Feeds Mold
Above 60% Relative Humidity
Unsealed dirt floors release moisture into the crawl space all year. Once relative humidity climbs above 60%, mold colonization on joists and subfloor begins. Dehumidification alone is not enough. The vapor source at the ground has to be capped before humidity can be controlled reliably.
Sagging Floors Start At The Sills
Sill Plate And Joist Rot
Prolonged moisture attacks sill plates and joist ends first. By the time squeaks and dips show up on the finished floor above, rot has usually been active for years. Structural repair without correcting the water source is a short fix that fails again within a season or two.
Pest Pressure Compounds Damage
Rodents, Insects, Carpenter Ants
Damp, unsealed crawl spaces are ideal nesting conditions. Rodent waste contaminates insulation and air. Carpenter ants follow soft, moist wood. Termite activity is more common in crawl spaces than in full basements. Exclusion is part of remediation, not an optional add-on.
Insulation Becomes The Problem
Fiberglass Holds Moisture And Waste
Fiberglass batts held up by wire hangers sag when they absorb moisture, trap rodent waste, and lose R-value. Removing the failed insulation is part of remediation. Installing new insulation without addressing moisture simply repeats the original failure.
Energy Loss And HVAC Strain
Higher Humidity, Harder Cooling
A wet crawl space drives up whole-house humidity, which makes cooling systems work longer to hit setpoint. Encapsulation paired with a dehumidifier typically reduces HVAC runtime and extends equipment life. The fuel and utility savings often offset a meaningful portion of the project cost.
Crawl Space Encapsulation, Done Right
Vapor barrier, dehumidification, and a sealed, dry crawl space, watch the full encapsulation process step by step.

Our crawl space was soaking wet every spring. The crew removed the old insulation, treated the joists, and sealed everything with a thick vapor barrier and a dehumidifier. The musty smell upstairs is gone.
Andrew P.
Full EncapsulationRodent damage in the insulation had been building for years. They hauled it all out, sealed the entry points, sanitized the framing, and rebuilt the vapor barrier. Clear photos and warranty paperwork at the end.
Christine V.
Pest And Insulation RemovalWe were selling and the inspector flagged mold under the house. Green Restoration handled the remediation, vapor barrier, and dehumidifier, and the reinspection came back clean. Closing stayed on schedule.
Jennifer R.
Mold And EncapsulationOur floors were getting springy near the kitchen. The scope report found rim joist rot, which we repaired, and then they encapsulated the whole crawl space. Floors feel solid again.

Crawl Space Cleanup FAQs
Clear answers on encapsulation, dehumidification, pest exclusion, structural rot, and warranty coverage for crawl space work across Connecticut, New York, and Massachusetts.
Musty odor on the main floor, persistent allergy complaints, springy or sagging floors, rodent activity, high humidity readings (above 60%), visible moisture or standing water on the crawl floor, and fiberglass insulation that is falling out of the joists are the most common signs. A full walkthrough with a moisture meter and thermal camera confirms scope before any quote is issued.
Every building science authority now recommends encapsulation over traditional venting in the Connecticut, New York, and Massachusetts climate. Vented crawl spaces pull in humid outdoor air that condenses on cool framing and drives mold growth. A sealed, dehumidified crawl space holds stable conditions year-round and typically improves indoor air quality, structural longevity, and HVAC efficiency.
Basic vapor barrier replacement typically ranges from $2,500 to $6,000. Mold remediation plus vapor barrier ranges from $6,000 to $15,000. Full encapsulation with dehumidifier, sealed vents, and perimeter drain ranges from $12,000 to $30,000 depending on size, access, and structural scope. Every estimate is written, itemized, and backed by scope photos, moisture readings, and a fixed quote.
Sudden water events (burst pipe, storm intrusion, sump pump failure) are typically covered. Gradual moisture damage and long-term mold are not. We review the policy before starting, document the cause, and coordinate direct billing on covered events. The fully itemized scope with cause-of-loss narrative is delivered to the adjuster in a package ready for approval.
We size the unit based on cubic footage, infiltration load, and target relative humidity below 55%. A properly sized commercial-grade unit draws fewer hours, lasts longer, and holds setpoint reliably. Under-sized big-box dehumidifiers cycle constantly, fail early, and leave humidity high enough for mold to return.
