We Know Long Island Basements

Diamond Masonry & Waterproofing LLC has been solving basement water problems for Glen Head homeowners who need real solutions. We understand how Long Island’s soil conditions and coastal weather create unique challenges for your foundation.

Our approach combines the right materials with proper installation techniques. No shortcuts, no temporary patches that fail in two years.

Basement Waterproofing Process Glen Head

Here's How We Keep Water Out

First, we inspect your basement to identify exactly where water enters and why. We check foundation walls, floors, window wells, and the area around your home’s exterior.

Next, we create a waterproofing plan that addresses your specific water issues. This might include interior drainage systems, exterior excavation and sealing, or crack repairs depending on what your basement needs.

Then we install the waterproofing system using professional-grade materials designed for Long Island conditions. We work efficiently to minimize disruption while ensuring every detail is done right.

Finally, we test the system and walk you through what we’ve installed so you understand how it protects your basement going forward.

Complete Waterproofing Services Glen Head

Everything Your Basement Needs

Our waterproofing services cover both interior and exterior solutions. Interior work includes drainage systems, sump pump installation, and wall treatments that redirect water before it causes damage.

Exterior waterproofing involves excavating around your foundation to apply waterproof membranes and improve drainage. We also handle foundation crack repairs and window well waterproofing.

Each job includes proper materials for Long Island’s climate and soil conditions. We use basement sealers and waterproofing systems that handle the moisture levels and freeze-thaw cycles common in Nassau County.

How much does basement waterproofing cost in Glen Head?

Basement waterproofing costs depend on your home’s specific needs and the extent of water problems. Interior solutions like drainage systems typically cost less than full exterior excavation and sealing. Most Glen Head homeowners invest between $3,000-$15,000 for comprehensive waterproofing, but we provide exact pricing after inspecting your basement. The investment pays for itself by preventing costly flood damage and protecting your home’s value. We’ll give you a detailed estimate that breaks down exactly what work your basement needs.

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 and sump pumps to redirect it safely away. Exterior waterproofing stops water before it reaches your foundation walls by applying waterproof barriers and improving drainage around your home’s perimeter. Interior solutions work well for minor seepage and are less disruptive to install. Exterior waterproofing provides more comprehensive protection but requires excavation. Many Long Island homes benefit from combining both approaches for complete water protection.

How long does basement waterproofing take to complete?

Most interior waterproofing projects take 2-4 days depending on your basement size and complexity. Exterior waterproofing typically requires 3-7 days because of excavation and material curing time. Weather can affect exterior work timing, especially during Long Island’s wet seasons. We schedule projects to minimize disruption to your routine and complete work efficiently without rushing important details. You’ll know the timeline upfront so you can plan accordingly. Emergency repairs for active leaks can often be addressed within 24-48 hours.

Will waterproofing work for my older Glen Head home?

Older homes actually benefit most from professional waterproofing because they were built before modern moisture protection standards. Many Glen Head homes from the 1950s-1980s have foundation issues that develop over time as materials age and settle. We regularly waterproof older homes and understand the specific challenges they present. The key is using the right approach for your home’s construction type and current condition. Age isn’t a barrier to effective waterproofing – it’s often the reason waterproofing becomes necessary and provides the most value.

Do you guarantee your basement waterproofing work?

Yes, we stand behind our waterproofing installations with warranties that cover both materials and workmanship. Warranty terms vary based on the specific systems installed and work performed. Interior drainage systems typically carry longer warranties than exterior applications due to different environmental factors. We use quality materials designed for Long Island conditions and install them according to manufacturer specifications to ensure warranty coverage remains valid. If water problems develop related to our work, we’ll return to address them at no additional cost during the warranty period.

When is the best time to waterproof my basement?

The best time is before you have major water damage, but we can waterproof basements year-round. Spring and fall offer ideal conditions for exterior work with moderate temperatures and lower rainfall. However, don’t wait if you’re experiencing active leaks – water damage gets worse over time and becomes more expensive to repair. Winter waterproofing is possible for interior solutions and emergency repairs. If you’re planning ahead, scheduling during drier months allows for optimal installation conditions and gives you protection before the next heavy rain season hits Long Island.
