Crawl Space Repair in Pierce & Kitsap County

From standing water and flooding to structural damage — we fix the root cause, not just the symptoms.

COMMON CRAWL SPACE PROBLEMS WE FIX

Years of moisture exposure in Pacific Northwest crawl spaces create compounding damage. We diagnose
and repair every layer — structural, biological, and drainage.

• Sump Pump Failure

• Damaged Vapor Barriers

• Foundation Cracks

• Musty Air

• Drainage Failure
  

WHAT OUR REMEDIATION PROCESS COVERS

Step 1 — Comprehensive Inspection
Full crawl space documentation including moisture readings, structural assessment, mold testing, and
drainage mapping. We identify every problem before work begins.

Step 2 — Moisture Source Elimination
We identify and eliminate the source — whether that's drainage failure, foundation cracks, venting issues, or
a failed vapor barrier. Treating mold without eliminating its moisture source is temporary at best.

Step 3 — Structural Repair

All compromised structural elements — rotted joists, damaged sill plates, deteriorated beams — are
repaired or replaced using commercial-grade lumber and hardware.

Step 4 — Full Encapsulation
Once the space is clean and repaired, we install a complete encapsulation system — drainage, 20-mil vapor
barrier, and dehumidification — to prevent any recurrence.

Step 5 — Ongoing Prevention Plan
We provide a documented maintenance schedule and optional annual inspection service to ensure
long-term protection of your investment.

SIGNS YOU MAY NEED CRAWL SPACE REPAIR

These warning signs often indicate problems requiring full remediation to eliminate safely:

• Musty or earthy odors throughout your home
• Increased allergy or respiratory symptoms
• Cold floors in winter despite adequate heating
• Unusually high energy bills
• Visible mold, dark staining, or standing water
• Evidence of pest activity (droppings, gnaw marks, nesting material)
• Soft, bouncy, or sagging floors above the crawl space
• Recent flooding or plumbing leak in the crawl space area
If you're experiencing multiple symptoms, remediation — not just repair — is likely the appropriate response
