Professional Structural Drying Services for Paso Robles Contractors & Builders

Our Construction Drying Services

Pre-Flooring Moisture Testing Before installing finished floors, we test:

Concrete Slabs:

• Calcium chloride testing (ASTM F1869): Measures moisture vapor emission rate
• Relative humidity testing (ASTM F2170): Measures internal slab RH at 40% depth
• Surface moisture testing: Confirms surface is installation-ready

Acceptable levels:

• Hardwood floors: <3 lbs/1000 sq ft/24hr, <75% RH
• Laminate/vinyl: <4 lbs, <85% RH
• Tile: <5 lbs, <90% RH

Wood Subfloors:

• Moisture meter readings (pin-type and pinless)
• Acceptable: 12-14% MC for most applications
• Must be within 4% of flooring material MC

Certification Documentation: We provide written reports certifying moisture levels meet manufacturer requirements—protecting you from warranty disputes.

Accelerated Structural Drying When projects can’t wait months for natural drying:

Equipment Deployment:

• Commercial dehumidifiers (150-200 pint/day capacity)
• Air movers creating airflow across surfaces
• Heat (if appropriate for accelerating evaporation)

Typical Timelines:

• Concrete slab drying: 2-6 weeks (vs. 6+ months natural)
• Framing lumber drying: 3-7 days
• Post-flood construction: 5-10 days

Cost: $500-2,000/week depending on square footage and equipment needs

Water Intrusion During Construction Storms don’t respect construction schedules. When jobsites get wet:

Emergency Response:

• Remove standing water
• Extract from saturated materials
• Set up temporary weather protection
• Deploy drying equipment immediately

Damage Assessment:

• Determine what can dry vs. requires replacement
• Document for builder’s risk insurance
• Provide timeline for drying completion

Drying to Specification:

• Monitor daily moisture readings
• Adjust equipment placement
• Document progress for inspectors/owners

Common Scenarios:

• Slab flooded before roof completion
• Drywall soaked during installation
• Lumber packages exposed to rain
• Interior finishes damaged by roof leaks

Post-Plumbing Test Drying Plumbing pressure tests sometimes reveal leaks—after drywall installation. We:

• Extract water from walls and ceilings
• Dry insulation if salvageable
• Prevent mold in hidden cavities
• Document moisture levels before closing walls

Moisture Mapping for Due Diligence Before purchasing job sites or buildings:

• Complete moisture assessment
• Identify hidden water damage
• Provide reports for negotiations
• Recommend remediation scope

Why Contractors Choose Rock Solid

Fast Response: Construction delays cost thousands per day. We respond within hours to keep projects moving.

Proper Equipment: We own commercial-grade equipment—no waiting for rentals. Equipment arrives with trained operators.

Certified Testing: IICRC-certified technicians perform ASTM-compliant testing recognized by flooring manufacturers.

Insurance Expertise: We document for builder’s risk claims, helping recover costs from weather or plumbing failures.

Professional Documentation: Detailed reports with moisture readings, equipment logs, and photos satisfy inspectors and warranty requirements.

No Conflicts: We dry and test—we don’t install flooring or do construction. Our only interest is accurate results.

Weekly drying service: $300-800/week (monitoring + adjustments)

Construction Drying Timeline

Consultation & testing: Same day or next day
Equipment mobilization: Within 24 hours
Typical drying duration:

• Concrete slab: 2-6 weeks
• Wood framing: 3-10 days
• Drywall/plaster: 3-7 days
• Water intrusion: 5-14 days

Final testing & certification: 1-2 days after reaching target levels

Common Construction Moisture Problems

Green Concrete: Concrete releases moisture for months. Installing flooring too early causes:

• Adhesive failure
• Plank cupping or crowning
• Mold under flooring
• Delamination

Wet Lumber: Framing lumber often arrives at 19-25% MC (too wet). Installing drywall and paint traps moisture, causing:

• Mold inside walls
• Drywall fastener pops
• Warping studs cracking drywall

Weather Delays: Open framing exposed to rain absorbs moisture. Without drying:

• Mold begins in 24-48 hours
• Insulation becomes ineffective
• Wood swells, complicating finish work

HVAC Not Operating: Many builders delay HVAC startup until near completion. Without climate control:

• High humidity slows drying
• Condensation forms overnight
• Materials equilibrate to ambient conditions (too wet)

Preventing Moisture Issues: Best Practices

During Construction:

• Cover materials during delivery and storage
• Close structures quickly (roof, windows)
• Run HVAC early for humidity control
• Schedule moisture testing before flooring

Before Flooring Installation:

• Test concrete at multiple locations
• Verify subfloor MC with meter
• Acclimate flooring materials 72+ hours on-site
• Don’t install during rainy periods without climate control

After Water Events:

• Call drying professionals immediately
• Don’t close up wet areas
• Document everything for insurance
• Test before proceeding
