Location: Smithtown, NY
Project Scope: Waterproofing, mold remediation, window well installation, and basement wall insulation

Client Concerns

The homeowners in Smithtown, NY, reached out to Zavza Seal LLC with multiple issues concerning their basement, including:

1. Water Intrusion: Persistent leaks along the south basement foundation wall.
2. Mold Growth: Affected the entire basement, posing health risks and potential structural damage.
3. Aging Window Wells: Ineffective drainage leading to water seepage around the windows.
4. Lack of Insulation: Poor temperature control and energy inefficiency throughout the basement walls.

Inspection and Diagnosis

Our team conducted a thorough inspection and identified four key areas requiring attention:

1. South Basement Foundation Wall:
   1. Multiple cracks and signs of water intrusion were evident along approximately 68 linear feet, including extensions at the southeast and southwest corners.
2. Mold in the Basement:
   1. Visible mold patches and musty odors indicated extensive contamination on walls, wood surfaces, and storage items.
3. Window Wells:
   1. Existing window wells lacked proper waterproofing and drainage, causing water to pool near the foundation.
4. Basement Wall Insulation:
   1. The walls were uninsulated, leading to heat loss and limited utility of the basement space.

Solution Implemented

1. South Basement Foundation Wall Waterproofing

To address the foundation wall issues:

• Crack Repair:
  1. Repaired all cracks using a 4.5 oz reinforced fibermesh, sandwiched by 7,000 PSI Basecrete waterproofing cement for a robust, watertight seal.
• Waterproofing Application:
  1. Applied a seamless waterproofing layer across the subject area to prevent future water intrusion.

2. Comprehensive Mold Remediation

As a licensed mold remediation Smithtown, NY company, we implemented the following:

• Disinfection:
  1. Sprayed exposed surfaces with an all-natural disinfectant to eliminate mold and mildew while repelling rodents.
• Sanitization:
  1. Wire-brushed and sanitized affected areas, shaving wood surfaces where necessary to remove mold traces.
• Encapsulation:
  1. Applied a water-based fungicidal coating containing EPA-registered antimicrobials to inhibit future microbial growth.
• Air Quality Management:
  1. Operated two dehumidifiers and two H13 HEPA-filtered air scrubbers for three days to ensure clean, mold-free air.

3. Window Well Installation

For improved window drainage and waterproofing:

• Excavation and Waterproofing:
  1. Excavated to 30 inches below the window openings and applied liquid membrane waterproofing to the below-grade wall area.
• Installation:
  1. Reinstalled one existing window well and installed one new well and frame, sealed and fastened securely to the foundation.
• Drainage System:
  1. Installed a self-contained drainage system to the footing and added gravel for proper filtration and drainage.
• Backfill:
  1. Restored the area to its original grade after installation.

4. Basement Wall Insulation

To enhance energy efficiency and prepare for future finishes:

• Polyethylene Foam Installation:
  1. Covered approximately 1,300 sq. ft. of walls with R-15 closed-cell polyethylene foam reinforced with reflective foil.
• Wood Stud Matrix Installation:
  1. Constructed a wood stud framework to facilitate future installation of drywall.
