What You Get With Proper Waterproofing

Your basement becomes the space you actually want to use. No more moving everything to higher shelves when rain’s in the forecast. No more that musty smell that hits you when you open the basement door.

You get a dry foundation that isn’t slowly deteriorating from constant moisture exposure. Your stored belongings stay protected. If you’ve got a finished basement or you’re planning to finish it, you can actually trust that the space will stay livable.

The bigger picture is simple: you stop worrying about water damage every time it storms. Your home value stays protected, and you’re not dealing with the health concerns that come with basement moisture and mold growth.

Waterproofing Company Floral Park NY

We Handle Both Problems

Diamond Masonry & Waterproofing LLC handles the masonry side and the waterproofing side of your basement issues. That matters because water problems usually involve both – foundation cracks that need proper repair and waterproofing systems that need to be installed correctly.

We’ve been working on Long Island properties long enough to know how the soil conditions and water table here create specific challenges. Clay soil doesn’t drain well, and that means exterior solutions often need to work alongside interior systems.

You’re dealing with contractors who understand both the structural repairs and the waterproofing technology needed to keep your basement dry long-term.

Basement Waterproofing Process Floral Park

Here's How We Approach It

We start with a thorough inspection to identify where water is coming from and why. Sometimes it’s obvious foundation cracks, sometimes it’s hydrostatic pressure pushing water through the walls, and sometimes it’s both.

Based on what we find, we recommend either interior waterproofing, exterior waterproofing, or a combination approach. Interior systems typically involve drainage and sump pump installation. Exterior work means excavating around the foundation to apply waterproof membranes and improve drainage.

For foundation cracks, we handle the masonry repairs first, then apply appropriate sealers and waterproofing materials. The goal is addressing the root cause, not just treating symptoms. Once the work is complete, you get a system designed to handle the specific water issues your property faces.

Basement Sealing Services Floral Park

What's Included In Our Service

You get a complete assessment of your basement’s water issues and a clear explanation of what needs to be done. We handle foundation crack repair using proper masonry techniques, not just surface patches that fail in a few months.

Our waterproofing services include both interior and exterior options depending on your situation. Interior basement waterproofing involves drainage systems, sump pumps, and wall treatments. Exterior basement waterproofing means excavation, membrane application, and drainage improvements around your foundation.

We also provide basement wall sealer applications and ongoing maintenance recommendations. Since we’re local to Floral Park, we understand how seasonal weather patterns and soil conditions affect basement moisture, and we design solutions accordingly.

What's the difference between interior and exterior basement waterproofing?

Interior waterproofing manages water that’s already trying to enter your basement by installing drainage systems, sump pumps, and applying sealers to interior walls. It’s typically less expensive and doesn’t require excavation. Exterior waterproofing prevents water from reaching your foundation walls in the first place by applying waterproof membranes and improving drainage around the outside of your foundation. It requires excavation but addresses the problem at its source. Many properties benefit from a combination approach depending on the severity of water issues and soil conditions.

How long does basement waterproofing last?

Quality waterproofing systems typically last 15-25 years when installed properly, though exterior membranes can last even longer. The lifespan depends on the materials used, installation quality, and local soil conditions. Interior drainage systems may need pump maintenance every few years, but the main waterproofing components are designed for long-term performance. We use materials rated for Long Island’s clay soil and moisture conditions, and we provide maintenance guidance to help you get maximum life from your waterproofing investment.

Can you waterproof a basement that already has water damage?

Yes, but we need to address any structural damage first. If there’s been significant water intrusion, we inspect for foundation damage, deteriorated mortar joints, or compromised wall integrity. Any necessary masonry repairs get completed before waterproofing installation. We also assess whether existing moisture has created mold issues that need remediation. The key is ensuring we’re waterproofing a structurally sound foundation, not just covering up existing problems that will continue to worsen over time.

What causes basement water problems in Floral Park specifically?

Floral Park’s clay soil doesn’t drain well, which creates hydrostatic pressure against foundation walls during wet periods. The relatively high water table on Long Island means groundwater can become an issue, especially in older homes with foundations that weren’t built with modern waterproofing standards. Heavy rains can overwhelm inadequate drainage systems, and foundation settling over time creates cracks that allow water entry. These conditions often require both interior and exterior solutions to effectively manage water intrusion.

How much does basement waterproofing cost?

Interior waterproofing typically ranges from $3,000-$8,000 depending on basement size and system complexity. Exterior waterproofing costs more due to excavation requirements, usually $8,000-$15,000 or higher for comprehensive solutions. Foundation crack repairs can range from a few hundred to several thousand dollars depending on severity. We provide detailed estimates after inspecting your specific situation because every basement has different challenges. The investment often pays for itself through prevented damage and increased home value.

Do you guarantee your waterproofing work?

Yes, we warranty our waterproofing installations, though warranty terms vary by service type and materials used. Interior drainage systems typically come with multi-year warranties on both materials and workmanship. Exterior waterproofing warranties can extend even longer given the permanence of those solutions. We also provide clear maintenance guidelines to help ensure your system performs as designed. Any warranty concerns get addressed promptly because our reputation in the Floral Park community depends on customer satisfaction and long-term system performance.
