Professional Detection, Drying & Full Reconstruction
When a slab leak occurs beneath your home or commercial building, the damage is often already spreading before you see visible signs. Water trapped beneath concrete slabs migrates into flooring, walls, framing, and insulation—creating structural issues that worsen by the hour.
RCS Builders is a
full-service water damage restoration company providing
professional slab leak water damage repair across Greater Phoenix. From emergency water removal and moisture detection to
structural drying and full reconstruction, we manage the entire process so nothing is missed.
Whether the leak is under tile, stone, carpet, or laminate, this guide explains
what slab leaks cause, what to do immediately, how drying works, and how insurance typically applies.
What Is a Slab Leak?
A slab leak occurs when a
water supply or drain line breaks beneath a concrete foundation. Because the leak is hidden, water can spread undetected for days or weeks—causing extensive damage before surfaces show visible signs.
Common causes include:
- Aging or corroded plumbing lines
- Shifting soil or foundation movement
- High water pressure
- Poor pipe installation
- Hard water mineral buildup (very common in Arizona)
Warning Signs of Slab Leak Water Damage
Homeowners and property managers often notice:
- Warm or damp spots on flooring
- Cracked or lifting tile and grout
- Sudden increases in water bills
- Damp baseboards or walls far from fixtures
- Musty odors or increased indoor humidity
- Flooring that feels soft or hollow
If any of these appear,
immediate professional drying and moisture mapping is critical.
Our Slab Leak Water Damage Repair Process
RCS Builders follows an
insurance-approved, documentation-driven process to stop damage fast and restore structures correctly.
1. Moisture Detection & Damage Mapping
Using thermal imaging and professional moisture meters, we identify:
- Hidden water beneath slabs
- Moisture inside walls and flooring
- Affected insulation and framing
This ensures
nothing is missed or left wet.
2. Emergency Water Extraction
If water has surfaced, we perform
rapid extraction to prevent further absorption into building materials.
3. Professional Structural Drying
We deploy commercial-grade equipment to dry:
- Flooring and subfloors
- Walls and insulation
- Cabinets and built-ins
- Structural framing
Moisture readings are monitored daily and documented.
4. Controlled Demolition (When Needed)
Only damaged materials are removed—nothing unnecessary. This limits rebuild scope and keeps insurance aligned with actual damage.
5. Full Reconstruction & Repairs
Unlike mitigation-only companies,
RCS Builders completes the rebuild, including:
- Drywall replacement
- Flooring repair or replacement
- Cabinet and trim restoration
- Paint and finish work
One contractor. One scope. One timeline.
How Homeowners Insurance Handles Slab Leak Damage
Most homeowners insurance policies cover
sudden and accidental water damage, including slab leaks that damage flooring, walls, and structural materials.
However, coverage typically depends on:
- How quickly the leak is discovered
- Whether damage was sudden vs. long-term
- Proper mitigation and documentation
Major insurance carriers—including
USAA—explain that while
damage caused by a slab leak is often covered, the cost to repair the broken plumbing line itself may not be.

RCS Builders provides
photos, moisture logs, drying reports, and scope documentation to support insurance claims and help avoid disputes. Coverage varies by policy and carrier. RCS Builders does not determine coverage but provides documentation to support the claims process.
Why Fast Slab Leak Response Matters
Delaying slab leak mitigation can lead to:
- Structural deterioration
- Mold growth
- Flooring and cabinet failure
- Increased reconstruction costs
- Insurance complications
Fast professional drying
limits damage, shortens timelines, and protects property value.
