The Problem: Mold and Structural Damage in a Home Theater, Mt. Sinai, NY

A homeowner in Mt. Sinai, NY, reached out to Zavza Seal after discovering signs of mold growth and water damage in their movie theater room, located in the basement level of the home. The client noticed:

• A musty odor developing over time
• Discoloration and bubbling on the lower sheetrock
• Visible mold growth on the baseboards and insulation
• Cracks forming at the corner and along the basement foundation walls

Inspection & Findings

Upon detailed inspection by our certified mold abatement supervisor, we confirmed:

• Active mold growth affecting the bottom 2 feet of insulation, framing, and sheetrock
• Two structural cracks, running approximately 15 linear feet across the corner and adjacent foundation wall
• Water seepage likely caused by hydrostatic pressure from the surrounding soil

Given the nature of the room and its purpose, the homeowner wanted a complete, professional-grade solution that would address:

• Mold remediation per NY State guidelines
• Structural crack repair and waterproofing
• Full restoration of interior finishes

The Solution: Mold Remediation and Waterproof Structural Repair

At Zavza Seal, we implemented a two-phase, problem-specific solution to fully restore and protect the basement theater room.

Phase 1: Mold Remediation and Interior Demolition

✅ Step 1: Selective Demolition

To eliminate all mold-contaminated materials:

• We cut and disposed of the bottom 2 feet of sheetrock
• Removed the bottom 1 foot of framing studs
• Removed the bottom framing plate
• Cut and removed the bottom 2 feet of insulation

This ensured complete removal of all mold-affected organic material, preventing any regrowth.

✅ Step 2: Mold Remediation by NYS-Certified Supervisor

Our licensed mold abatement supervisor conducted a full remediation process following New York State mold protocols, including:

• HEPA vacuuming
• Application of antimicrobial solutions
• Negative air pressure containment to prevent cross-contamination
• Moisture monitoring to ensure all surfaces were fully dry

Phase 2: Structural Crack Repair & Waterproofing

The theater room also had two structural cracks located at the corner where two walls meet, extending along the foundation wall—a total of 15 linear feet. These cracks were allowing moisture to seep into the room.

✅ Step 3: Crack Preparation

We used alloy steel mason chisels to chase the cracks and remove loose material, exposing clean concrete for treatment.

✅ Step 4: Injection Ports & Structural Filling

We drilled injection ports every 6 inches along the cracks and filled them with high-strength epoxy and urethane formulations to:

• Restore the structural integrity of the wall
• Seal and waterproof the cracks from inside out

✅ Step 5: Reinforced Waterproofing Cement System

To ensure long-term durability:

• We applied a layer of 7050 psi waterproofing cement
• Installed a 4.5 oz fiberglass mesh for added strength
• Applied a second layer of 7050 psi cement over the mesh to complete the seal

Phase 3: Restoration and Finishing

With the waterproofing and mold remediation complete, we began the restoration process, returning the space to a clean, finished state.

✅ Step 6: Reinstallation

• New framing studs and bottom framing plate were installed
• Two feet of new insulation added to match thermal performance
• We hung new sheetrock, taped, compounded, and sanded the surface

✅ Step 7: Painting & Finish

Finally, we painted the wall to match the existing interior using paint provided by the homeowner, seamlessly blending the repaired area with the rest of the room.

✅ The Result: A Safe, Dry, and Fully Restored Theater Room

In this case, exterior foundation waterproofing was the most reliable and long-lasting solution. Unlike temporary interior fixes, this approach:

• Mold-free air and improved indoor air quality
• Elimination of water seepage during heavy rains
• Reinforced foundation integrity
• A visually seamless finish in their custom theater space
• Peace of mind from knowing the job was done by a certified, licensed team
