5 Signs You Need to Call a Basement Waterproofing Company Larchmont, NY

5 Signs You Need to Call a Basement Waterproofing Company Larchmont, NY

Water damage is one of the main causes of structural damage in homes. Your basement is especially vulnerable to water damage because it is frequently in contact with water and moisture from the soil in which the foundation is embedded.

Water may reach the basement and its walls due to a burst or leaking pipe, poorly positioned downspouts and gutters, and flooding among other incidents. You may assume that you should waterproof your basement only when there is an obvious need to do repair work, such as when the basement floods. But by the time you decide to do repairs, it may be too late and the work required may be too complicated and costly.

You should not ignore any minor sign that might suggest that your home needs basement waterproofing. Knowing how to identify early signals that your basement requires waterproofing can help you save a lot of money and time. By acting early, you also get time to plan and work with a professional company at the most convenient time and within your budget.


You need to call a basement waterproofing company when you see any of the following signs.

  1. Sparkly Deposits on Basement Walls

If your basement has shimmers, this may be because of efflorescence. Efflorescence entails dissolved minerals moving through materials such as a wall or stucco and getting deposited on the surface. Shimmers on your basement’s walls are a clear sign that water is seeping into the basement.

  1. Damp Air and Musty Odor

Most signs of water intrusion tend to be unobvious in that you may not see water on the floor or walls of your basement. However, even if you don’t see pools of water in the basement, you may still feel some coldness or bad smell.

Musty odors are likely to be more pronounced if mold is hidden in some areas of your basement. If the basement feels damp, smelly, and stuffy, you should let a competent basement waterproofing technician check it.


  1. Visible Mold Growth

Mold thrives in damp areas. So, if you can see mold in your basement, this is a clear sign that the basement gets damp and needs to be waterproofed.

  1. Water Marks on the Floor and Walls

The floor and walls of your basement should be dry unless there is a specific source of a spill or leak into the basement.

  1. Cracks

Cracks on basement walls can allow water to seep into the basement. Since the cracks can expand over time, you need to have them sealed as soon as you spot them.|
