Why Get Cold Cellar Repair?

Signs that Your Cold Cellar Needs Waterproofing

A cold cellar can be a valuable addition to any home, providing extra storage space and the ability to keep food and beverages at the perfect temperature. However, if a cold cellar is not properly waterproofed, it can lead to costly damage and potential health hazards. Here are some signs that indicate your cold cellar may be in need of waterproofing:


  • Moisture and Condensation - excessive moisture or condensation on walls, floors, or ceilings is a telltale sign of water infiltration. Check for dampness or wet spots regularly, as this can lead to mold growth and structural damage.

  • Musty Odors - a persistent musty smell in your cold cellar is a clear indication of water leakage. The odor is often caused by mold or mildew forming due to excessive moisture, which poses health risks for occupants.

  • Cracks or Gaps - inspect the walls and floor for cracks or gaps that allow water to seep through. These openings can result from aging foundations or improper construction techniques, allowing water to enter the space.

  • Peeling Paint or Wallpaper - if you notice peeling paint or wallpaper in your cold cellar, it usually suggests that moisture has entered through the walls. Waterproofing will help prevent further damage and protect your cellar from water intrusion.

  • Flaking Concrete - when exposed to excessive moisture over time, concrete surfaces may begin to deteriorate, leading to flaking or crumbling concrete. This not only compromises the structural integrity but also increases the likelihood of future leaks.

It often includes excavation, application of waterproofing membranes or coatings, and proper drainage systems. The benefit of exterior waterproofing is that it provides long-lasting protection against water damage, as it prevents water from reaching the interior walls and keeps the cold cellar dry.
