Why We All Need Basement Waterproofing – Let Del-Val Help You Protect Your Home

If you’ve noticed damp spots, water stains, or a musty smell in your basement—or even if no obvious signs are present yet—basement waterproofing may be essential for protecting your home in Delaware County. Basement waterproofing focuses on preventing water from entering your basement, helping to avoid costly structural damage, ruined belongings, and potential health concerns such as mold and mildew growth. Many homeowners don’t realize there’s an issue until damage has already begun, which is why proactive waterproofing is so important.


Basements are especially vulnerable because they sit below ground level, where water naturally collects. In Delaware County, heavy rainfall, clay-rich soils, and fluctuating groundwater levels can increase pressure against foundation walls. Water can find its way inside through small foundation cracks, poor exterior drainage, aging waterproofing systems, or even plumbing leaks. If your basement was waterproofed years ago, those systems may no longer perform as intended, as materials and sealants can deteriorate over time.


Common Causes of Basement Water Problems

  • Poor drainage: When rainwater pools around your foundation due to clogged gutters, improper grading, or saturated soil, it can seep through basement walls or floors.
  • Leaky or damaged pipes: Older plumbing or winter freeze-thaw cycles can cause cracks and slow leaks that introduce moisture into your basement.
  • Condensation: Warm, humid air coming into contact with cool basement walls can create ongoing dampness, even without active leaks.



How Del-Val Can Help

At Del-Val Basement Waterproofing, we provide proven solutions designed to keep basements dry and protected:

  • Interior waterproofing: A cost-effective approach that may include interior drainage systems, sump pumps, and specialized sealants to manage water after it enters.
  • Exterior waterproofing: A more comprehensive solution that involves excavating around the foundation to install waterproof membranes and improved drainage, stopping water before it reaches your basement.

Choosing the right waterproofing solution depends on your home’s specific conditions and the source of the moisture. Del-Val’s experienced team will assess your basement, identify the underlying issues, and recommend the most effective way to protect your Delaware County home and keep it dry, healthy, and secure year-round.

Frequently Asked Questions

  • How Much Does a Typical Basement Waterproofing Project Cost?

    You’re probably wondering about the cost of a typical basement waterproofing project. It’s not a one-size-fits-all answer. Prices can vary greatly, depending on your home’s specifics and the waterproofing method chosen.


    On average, you might spend between $3,000 to $10,000. However, major repairs could exceed this range. It’s wise to get several estimates and ensure you’re not just going for the cheapest option, but the most effective one for your home.



  • How Long Does a Waterproofing Solution Usually Last?

    Ironically, you’re asking about longevity in an age of disposability. Yet, when it comes to basement waterproofing, longevity is key.


    Most waterproofing solutions are designed to last for the life of your home. However, it depends on the type of waterproofing system installed. Some systems, like interior water drainage, can last for decades without maintenance. Others, like exterior waterproofing, can last up to 10 years but may require regular upkeep.

  • Is Basement Waterproofing Covered Under Home Insurance?

    Typically, your home insurance doesn’t cover basement waterproofing. It’s viewed as a preventive measure, not a repair or replacement due to damage.


    Insurance may cover water damage if it’s sudden and accidental, like a burst pipe. But, it usually won’t cover damage from neglect or failure to maintain your property, including seepage or leaks over time.


    Always check your policy’s specifics, though, as coverage can vary.

  • Can I Live in My House During the Basement Waterproofing Process?

    Yes, you can continue living in your house during the basement waterproofing process. It’s a non-invasive procedure that doesn’t usually disrupt your daily routines.


    However, you might experience some noise and dust. It’s crucial to communicate with your contractor about the process and timeline to ensure your comfort and convenience.


    Prepare for minimal disruption, but remember, it’s a small price to pay for long-term protection against potential water damage.

  • What Are the Potential Health Risks if I Don’t Waterproof My Basement?

    If you neglect to waterproof your basement, you’re risking your health. Unchecked moisture can foster mold and mildew growth, causing respiratory issues like asthma and allergies.


    Dampness can also attract pests, contributing to disease spread. Moreover, poor air quality due to higher humidity levels can lead to respiratory problems and skin irritations.
