Case Study: Kitchen Dishwasher Leak Repair and Subfloor Waterproofing in Brooklyn, NY

Problem:

A homeowner in Brooklyn, NY contacted Zavza Seal after noticing recurring moisture and a musty odor coming from the kitchen area near the dishwasher. Over time, small leaks had gone unnoticed, allowing moisture to become trapped beneath the appliance. A prior attempt to control the issue with closed cell foam created a new problem by locking in moisture instead of allowing the area to properly dry.

During our inspection, we identified moisture buildup and compromised materials within a 36 x 36 inch area beneath the dishwasher. If left untreated, the trapped moisture could have led to mold growth, subfloor deterioration, and damage to surrounding cabinetry.

Solution:

Zavza Seal developed a targeted, minimally invasive solution focused on moisture removal, proper cleanup, and long term protection of the kitchen subfloor.

Our team carefully removed the dishwasher to gain full access to the affected area. The improperly installed closed cell foam was then removed and disposed of according to proper waste handling standards. This step allowed the area to dry correctly and prevented future moisture entrapment.

Once the space was cleaned and prepared, we ensured the subfloor area was stable and ready for appliance reinstallation. The dishwasher was then properly replaced, restoring full kitchen functionality while eliminating the source of ongoing moisture concerns.

Results:

  • Moisture source beneath the dishwasher was fully addressed
  • Trapped and ineffective closed cell foam safely removed
  • Subfloor area restored and left clean and dry
  • Dishwasher reinstalled with proper clearance and protection
  • Homeowner gained peace of mind knowing hidden water damage was resolved

Why This Matters for Brooklyn Homes?

Kitchen appliance leaks are a common but often overlooked cause of water damage in Brooklyn residences, especially in older buildings. Small leaks beneath dishwashers can quietly cause serious damage if moisture becomes trapped. Professional removal, inspection, and correct restoration are essential to prevent mold growth and costly structural repairs.

Zavza Seal specializes in identifying hidden moisture issues and delivering practical waterproofing solutions that protect homes from long term damage.
