What We Do

Engineered Crawl Space Solutions

Every service we offer is designed around one goal: permanently solving the moisture, mold, and structural problems threatening your home's foundation.

Service 01

Crawl Space Encapsulation

The gold standard in crawl space protection

Crawl Space Encapsulation

Full-system encapsulation seals your crawl space from ground moisture, outside air, and pest intrusion. We install a heavy-duty reinforced vapor barrier across the floor and walls, seal all vents, and condition the air — creating a clean, dry, controlled environment beneath your home.

Key Benefits

  • Eliminates ground moisture and condensation
  • Prevents mold and fungal growth
  • Improves indoor air quality throughout the home
  • Reduces heating and cooling costs
  • Deters pests and rodents
01

Moisture Assessment

We measure relative humidity, surface moisture, and identify all water entry points before any work begins.

02

Debris Removal & Prep

Existing insulation, debris, and old vapor barriers are removed and disposed of properly.

03

Barrier Installation

20-mil reinforced polyethylene barrier is installed across the floor and up all walls, sealed at every seam and penetration.

04

Vent Sealing & Conditioning

All foundation vents are sealed and a dehumidifier or conditioned air supply is installed to maintain optimal humidity.

Service 02

Drainage & Waterproofing

Redirect water before it becomes a problem

Drainage & Waterproofing

When water is actively entering your crawl space — through foundation walls, floor cracks, or hydrostatic pressure — encapsulation alone isn't enough. Our drainage systems capture and redirect water away from your foundation before it can cause damage.

Key Benefits

  • Eliminates standing water and flooding
  • Relieves hydrostatic pressure on foundation walls
  • Protects structural wood from rot
  • Works in conjunction with encapsulation
  • Backed by transferable warranty
Service 03

Structural Repair

Restore integrity to moisture-damaged framing

Structural Repair

Years of moisture exposure weaken the wood framing that supports your floors. Sagging, bouncing, or uneven floors are symptoms of structural damage that won't fix itself. We assess and repair damaged joists, beams, and support posts — restoring your home's structural integrity.

Key Benefits

  • Eliminates floor bounce and sagging
  • Prevents further structural deterioration
  • Restores load-bearing capacity
  • Addresses root cause, not just symptoms
  • Documented with before/after photos
Service 04

Mold Remediation

Eliminate mold at the source

Mold Remediation

Crawl space mold isn't just an aesthetic problem — it spreads through your home's air supply and poses real health risks. We identify and eliminate mold growth using EPA-registered treatments, then address the moisture conditions that allowed it to grow.

Key Benefits

  • Eliminates existing mold colonies
  • Treats wood framing with antimicrobial agents
  • Improves air quality throughout the home
  • Prevents recurrence with moisture control
  • Safe, EPA-registered treatment products
