Here's Exactly What We Do

We start with a thorough inspection of your basement and foundation. You’ll see exactly where water enters, why it’s happening, and what needs to be addressed. No guesswork, no surprises later.

Next, we prepare the affected areas properly. This means cleaning, repairing any foundation issues, and ensuring surfaces are ready for waterproofing materials to bond correctly. Shortcuts here cause failures later.

Then we apply professional-grade waterproofing systems – interior drainage, exterior membrane systems, or wall sealers depending on your specific situation. We use materials designed for Long Island’s soil conditions and climate challenges.

Finally, we test everything thoroughly and walk you through maintenance steps that keep your system working effectively for years to come.

What's Included in Your Waterproofing

You get both interior and exterior basement waterproofing options tailored to your home’s specific needs. Interior systems include drainage solutions and wall sealers that handle water before it becomes a problem. Exterior waterproofing involves foundation membrane application and proper drainage management.

Foundation crack repair addresses structural issues that allow water penetration. We don’t just seal over problems – we fix the underlying causes that create water entry points in the first place.

Basement sealing services include comprehensive moisture barriers and ventilation improvements that prevent humidity buildup. Your basement becomes a genuinely usable space instead of an area you avoid because of dampness or odors.

Professional basement waterproofing systems installed correctly typically last 15-25 years or longer, depending on the specific materials and methods used. Interior drainage systems and quality wall sealers are particularly durable when properly maintained. The key is using materials designed for Long Island’s specific soil conditions and seasonal weather patterns. We focus on permanent solutions rather than temporary fixes, which means you’re investing in long-term protection rather than repeated repairs. Regular maintenance like keeping gutters clean and ensuring proper grading around your foundation helps maximize your waterproofing system’s lifespan.
Long Island’s clay soil conditions create unique challenges for basement waterproofing. Clay doesn’t drain well, so water sits against foundation walls longer during heavy rains. Seasonal freeze-thaw cycles cause foundation settling and create small cracks where water enters. Poor drainage around the foundation, clogged gutters, and improper grading direct water toward your basement instead of away from it. Older homes often have foundation materials that weren’t designed for today’s weather patterns. Understanding these specific local factors is crucial for choosing waterproofing solutions that actually work long-term rather than just temporarily masking the problem.
The best choice depends on your specific water intrusion patterns, foundation condition, and budget considerations. Exterior waterproofing prevents water from reaching foundation walls in the first place, making it highly effective for severe water problems. However, it requires excavation and costs more upfront. Interior waterproofing systems manage water that does penetrate, directing it away safely through drainage systems. Many homes benefit from a combination approach – exterior work where excavation is practical and interior systems where it’s not. During our assessment, we’ll show you exactly where water enters and recommend the most cost-effective solution for your situation.
Basement waterproofing costs vary significantly based on your home’s size, the extent of water problems, and which solutions work best for your situation. Interior drainage systems typically range from $3,000-$8,000 for average basements. Exterior waterproofing involving excavation costs more, usually $8,000-$15,000 depending on accessibility and foundation condition. Simple crack repair and wall sealing projects might cost $1,500-$3,500. We provide detailed written estimates after assessing your specific situation, so you understand exactly what work is needed and why. Remember that professional waterproofing protects your home’s value and prevents much more expensive structural damage later.
Yes, proper basement waterproofing eliminates the moisture conditions that cause musty odors and mold growth. When water intrusion stops and humidity levels drop, existing odors disappear and new mold can’t establish itself. However, existing mold should be professionally remediated before waterproofing work begins. Waterproofing systems that include proper ventilation and moisture barriers create an environment where mold simply can’t thrive. You’ll notice improved air quality throughout your entire home, not just in the basement. The key is addressing water sources completely rather than just treating symptoms with dehumidifiers or temporary solutions that don’t solve underlying moisture problems.
If you see water stains on walls, notice musty odors, find standing water after rains, or discover white mineral deposits on foundation walls, you need professional assessment. Small amounts of condensation might be manageable with improved ventilation, but actual water intrusion requires waterproofing systems. Don’t wait for major flooding – early intervention costs much less than repairing extensive water damage. Signs like peeling paint, rust on metal items, or humidity that makes your basement uncomfortable indicate moisture problems that will worsen over time. We provide honest assessments that distinguish between minor issues you can handle yourself and serious problems requiring professional waterproofing solutions.
