What You Get With Proper Waterproofing

Your basement becomes the dry, usable space it should be. No more worrying about your belongings getting damaged during the next heavy rain. No more musty smells creeping upstairs or concerns about mold affecting your family’s health.

You get back that valuable square footage for storage or living space. Your home’s foundation stays protected from long-term water damage that could cost thousands down the road. Most importantly, you stop losing sleep over whether the next storm will flood your basement again.

The right waterproofing approach means you’re done dealing with this problem. Water stays outside where it belongs, and your basement stays dry year-round, even during Long Island’s wettest seasons.

Here's How We Stop Water Problems

First, we inspect your basement to determine exactly where water is entering and why. This isn’t guesswork – we need to understand whether you’re dealing with hydrostatic pressure, poor drainage, foundation cracks, or a combination of issues.

Next, we explain what we found and recommend the right solution. Sometimes that’s interior waterproofing with sealers and drainage systems. Other times, exterior waterproofing is necessary to address the problem at its source. We’ll tell you which approach makes sense for your specific situation.

Then we get to work using professional-grade materials and proven application methods. We protect your property during the process and clean up thoroughly when we’re done. You’re left with a basement that stays dry, backed by our workmanship warranty.

What's Included In Our Service

We handle both interior and exterior basement waterproofing depending on what your situation requires. Interior solutions include basement wall sealing, foundation crack repair, and moisture control systems. Exterior waterproofing involves excavation, membrane installation, and proper drainage setup.

Our basement sealing services use professional-grade sealers that create a permanent barrier against moisture intrusion. We also address any existing foundation issues that could compromise the waterproofing over time. Every job includes a thorough assessment of your current drainage situation.

You get honest recommendations about which approach will solve your problem most effectively. We don’t oversell services you don’t need, but we also don’t cut corners on the work that needs to be done right.

The location and severity of your water problem determines the best approach. Interior waterproofing works well for minor seepage through basement walls and can be done without major excavation. Exterior waterproofing is necessary when you have significant hydrostatic pressure pushing water through your foundation or when interior solutions haven’t resolved the problem. We’ll inspect your basement and explain which method will be most effective for your specific situation. Sometimes a combination approach works best.
Professional basement waterproofing should last decades when done correctly with quality materials. Interior sealers and coatings typically last 10-15 years, while exterior waterproofing systems can last 20-30 years or more. The longevity depends on factors like soil conditions, drainage around your home, and the quality of materials used. We use professional-grade products specifically designed for Long Island’s clay soil and weather conditions, and we back our work with a warranty so you have confidence in the investment.
Yes, effective basement waterproofing eliminates the moisture that mold and mildew need to grow. When we stop water from entering your basement and control humidity levels, we remove the conditions that allow these problems to develop. However, if you already have mold present, that needs to be addressed separately before waterproofing. We can recommend qualified remediation specialists if needed. Once your basement is properly waterproofed and dry, mold and mildew won’t be able to establish themselves.
Interior waterproofing typically causes minimal disruption and can often be completed in 1-2 days depending on your basement size. You’ll need to move items away from the walls we’re treating, but you can usually stay in your home normally. Exterior waterproofing involves excavation around your foundation, which is more disruptive and takes longer, usually 3-5 days. We protect your landscaping where possible and restore disturbed areas when we’re finished. We’ll explain exactly what to expect before starting any work.
Basic basement wall sealing is a surface treatment that can help with minor moisture issues, but true waterproofing addresses the underlying causes of water intrusion. Waterproofing includes proper drainage, addressing foundation cracks, and creating comprehensive moisture barriers. Simple sealers might work temporarily for light dampness, but they won’t solve serious water problems or prevent future issues. We evaluate your specific situation to determine whether basic sealing is sufficient or if you need comprehensive waterproofing for lasting results.
Properly waterproofed basements require minimal maintenance, but there are a few things that help preserve the system. Keep gutters clean and ensure downspouts direct water away from your foundation. Check for any new cracks in basement walls and address them promptly. Maintain proper ventilation to control humidity levels. Avoid storing items directly against basement walls even after waterproofing. We’ll provide specific maintenance guidelines based on the waterproofing method used in your basement and will be available if you have questions down the road.
