Project Overview:

A homeowner in Flushing, NY contacted our team with concerns about recurring water intrusion around the basement window well and unexplained moisture inside the garage. These issues were becoming more frequent after heavy rainfall and threatened the structural integrity of both areas.

After a detailed on site review, our waterproofing specialists identified two separate problem areas that required targeted solutions:

1. The exterior basement window well was not draining properly.
   
2. The garage showed signs of hidden water intrusion but the source was unclear.
   

This case study explains how Zavza Seal solved the first issue and conducted complimentary exploratory work for the second.

Problem:

1. Basement Window Well Not Draining

The homeowner noticed pooling water inside the exterior basement window well. When water levels rose, moisture would seep inside the basement wall. The well had soil buildup, no drainage layer, and no reliable system to channel water away.

Left untreated, this type of problem can cause structural damage, mold growth, and long term foundation deterioration. According to the International Association of Certified Home Inspectors, improperly drained window wells are one of the most common causes of basement moisture.

2. Water Intrusion in the Garage

Water stains were visible on the garage floor and lower wall. The homeowner could not pinpoint the origin. Since water intrusion can travel from hidden or unexpected pathways, we proposed exploratory work to diagnose the cause before recommending any repairs.

To help the homeowner, we provided this exploratory investigation as courtesy work at no cost.

Solution:

1. Basement Window Well Drainage Upgrade

Our team implemented a complete restoration and drainage improvement of the window well. The work included:

• Cleaning the well thoroughly
  All debris, soil buildup, and saturated organic material were removed to expose the footing and window frame.
  
• Installing a bed of gravel
  A fresh, graded gravel layer was placed at the base of the window well. This helps promote proper water percolation and prevents soil clogging.
  
• Adding a self contained drainage system
  We installed a small, internal drainage channel designed to move water down below the top of the footing. This ensures that water does not accumulate and rise toward the window.
  
• Installing a drainage grill
  A sturdy grill was added to help direct water into the drainage zone while keeping the system free of leaves and large debris.
  
• Installing a protective cover on the existing frame
  The final step was to protect the well from direct rainfall and snow accumulation. The clear cover helps improve long term efficiency and prevents future clogging.
  

This solution significantly reduced the risk of basement moisture and protected the window area for years to come. Window well drainage improvements are recommended by many building science organizations, including the U.S. Department of Energy.

2. Courtesy Exploratory Work for Garage Water Intrusion

To determine the source of moisture in the garage, Zavza Seal performed several tests including:

• Controlled water testing on exterior walls
  
• Inspection of garage window seals
  
• Foundation wall moisture readings
  
• Examination of potential slab cracks
  
• Checking adjacent exterior drainage patterns
  

After completing the investigation, our team shared detailed findings with the homeowner along with a customized scope of work to permanently resolve the issue. Since this step was provided as a courtesy, the homeowner appreciated the transparency and professionalism.

Results:

• The basement window well now drains properly and remains dry even during heavy rainfall.
  
• The homeowner has peace of mind knowing that water is being channeled safely away from the foundation.
  
• The garage moisture problem was correctly diagnosed, allowing the homeowner to move forward with proper waterproofing.
  
• With both issues addressed, the property is now better protected against water damage.
  

This Flushing, NY project highlights the value of thoughtful waterproofing and honest diagnostics. At Zavza Seal, we focus on long lasting solutions, clear communication, and doing what is right for the homeowner.
