Here's Exactly What Happens

First, we inspect your basement and exterior to find where water is actually entering—not just where you see it. Most water problems start outside your foundation, so we trace the real source.

Next, we explain whether you need interior waterproofing, exterior waterproofing, or both. No upselling, just honest assessment based on your specific situation and budget.

Then we get to work with professional-grade materials designed for Long Island conditions. We seal foundation walls, install proper drainage systems, and create barriers that stop water before it becomes your problem. You’ll know exactly what we’re doing and why we’re doing it.

Complete Water Protection Systems

We offer both interior and exterior basement waterproofing options, depending on what your situation actually needs. We apply basement wall sealer, install drainage systems, and use waterproofing materials that handle Long Island’s freeze-thaw cycles.

Our exterior basement waterproofing addresses the root cause by stopping water before it reaches your foundation. Interior basement waterproofing manages water that’s already found its way in, directing it away from your living space.

Every job includes proper basement sealing techniques, moisture barriers, and drainage solutions designed to work together as a complete system. No shortcuts, no temporary fixes that fail when you need them most.

It depends on where the water is coming from and your budget. Exterior waterproofing stops water before it reaches your foundation walls—it’s more comprehensive but requires excavation. Interior waterproofing manages water that’s already getting in by directing it to drains and sump pumps. Many Long Island homes need both because of our clay soil and high water table. We’ll inspect your specific situation and recommend the most effective approach for your home and budget, not just the most expensive option.
Yes, but only if it’s done right for our local conditions. Long Island’s clay soil holds water and expands when wet, creating constant pressure against foundation walls. Generic waterproofing approaches often fail here because they don’t account for this hydrostatic pressure. We use waterproofing systems specifically designed for clay soil conditions, including proper drainage, flexible sealers that move with soil expansion, and pressure relief systems. The key is understanding how water moves through clay soil and designing solutions that work with those conditions, not against them.
Quality basement waterproofing should last 15-20 years or more when installed correctly with professional-grade materials. The lifespan depends on the waterproofing method used, local soil conditions, and how well the system was designed for your specific situation. Exterior waterproofing typically lasts longer because it addresses the root cause, while interior systems may need maintenance or updates sooner. Cheap DIY sealers might last 2-3 years at best. We use commercial-grade materials designed for Long Island’s challenging conditions, and we’ll tell you upfront what kind of longevity to expect from your specific waterproofing solution.
Basement wall sealer is just one component of waterproofing—it’s not a complete solution by itself. Sealing basement walls can help with minor moisture issues, but it won’t stop serious water intrusion or address drainage problems. True waterproofing includes drainage systems, moisture barriers, proper grading, and sometimes interior collection systems that work together as a complete water management system. If you’re dealing with standing water, recurring leaks, or water damage, you need more than just sealer. We’ll assess whether simple basement sealing is enough for your situation or if you need comprehensive waterproofing.
Interior waterproofing typically takes 2-4 days with minimal disruption to your daily routine. You’ll need to clear the basement area we’re working on, and there will be some noise and dust, but you can stay in your home normally. Exterior waterproofing involves excavation around your foundation, which takes 3-7 days depending on access and soil conditions. This creates more disruption with equipment, trucks, and temporary landscaping disturbance. We’ll explain exactly what to expect for your specific project, help you prepare, and work efficiently to minimize the impact on your routine.
Simple moisture control might be DIY-friendly, but serious water intrusion requires professional waterproofing. DIY basement sealers from home improvement stores work for minor dampness but fail quickly with real water pressure. Professional waterproofing involves understanding drainage patterns, soil conditions, proper material selection, and installation techniques that most homeowners don’t have experience with. Long Island’s clay soil and water table conditions make this even more challenging. If you’re dealing with recurring water problems, foundation concerns, or want a solution that actually lasts, professional installation is worth the investment to avoid doing the job twice.
