"We contacted Indiana Foundation for a free inspection of our attached garage that we're turning into a bedroom for our handicapped son. We had several places that leaked where the wall meets the floor. A Mr John Hill did the inspection and then answered all our questions to our satisfaction. He was quite the professional but did not pressure us in any way, like most salesmen do. We decided to go ahead and schedule to get the waterproofing done. The cost was reasonable and it made sense to get it done now rather than wait for more damage to occur, making it more expensive. We look forward to meeting the crew. John Hill came as an inspector and left as a friend. Indiana Foundation is lucky to have him on their team."

Basement Waterproofing FAQs, answered by experts

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.
