"The job was done to satisfaction. I would not recommend due to the lack of communication and time management, I was scheduled for for an early appointment and no one showed, after I called it was pushed multiple times after that. I did agree to the price, but after consulting others I paid way too much for what was done. When it came time for the gentleman to collect payment you bet he was ontime, even a bit early."

Basement Waterproofing questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Yes, cleaning a crawl space is worth it. You might think you can ignore the area since it’s out of sight, but doing so can lead to pest infestations, mold, and other problems. Crawl space cleaning costs between $0.50 and $4 per square foot, but the cost to deal with pests or mold would be much higher.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.
