25 Years Protecting East Hills Homes

We’ve been serving East Hills and Nassau County for over 25 years. We understand the unique challenges that Long Island’s soil conditions and climate create for homeowners.

East Hills’ generous property sizes and extensive landscaping mean saturated soil creates significant hydrostatic pressure against foundation walls. We’ve completed over 500 projects across Nassau and Suffolk Counties, with more than 150 customer reviews backing our work.

We’ve seen how quickly foundation issues escalate when not addressed properly. That’s why we focus on permanent solutions that address the root cause, not just the symptoms.

Complete Foundation Protection Process

Our exterior membranes installation process starts with careful excavation around your foundation to expose the exterior walls down to the footer. This allows direct access to apply the waterproofing system where it’s most effective.

Next, we thoroughly clean the foundation walls and repair any existing cracks or damage. This surface preparation is critical for proper membrane adhesion and long-term performance.

We then apply the waterproof membrane using proven materials like polymer-modified asphalt or specialized sheet membranes. This creates a seamless, impermeable barrier that stops water before it can reach your foundation walls. The membrane is designed to handle hydrostatic pressure and resist Long Island’s freeze-thaw cycles.

Finally, we install proper drainage systems and carefully backfill the area with appropriate materials to support the waterproofing system’s long-term effectiveness.

What You Get With Professional Installation

Your exterior membranes installation in East Hills includes complete foundation assessment, professional-grade materials, and expert installation backed by warranty protection. We use quality waterproofing membranes designed specifically for Long Island’s challenging conditions.

East Hills properties face unique challenges due to the area’s soil composition and generous landscaping that can create significant water retention around foundations. We select the membrane system specifically to handle these local conditions, including the hydrostatic pressure that builds up during Long Island’s heavy rainfall periods and seasonal thaw cycles.

Our installation includes proper surface preparation, crack repair when needed, membrane application with proper overlap and sealing, and integration with drainage systems. All work is completed by our experienced technicians who understand how Long Island’s varying soil conditions—from clay-heavy areas to more sandy compositions—affect foundation waterproofing requirements.

How long does exterior membrane installation take in East Hills?

Most exterior membrane installations in East Hills take 3-5 days depending on your foundation size and soil conditions. The process involves excavation, surface preparation, membrane application, and backfilling.

Weather conditions can affect the timeline since the membrane needs proper curing time. We schedule the work to minimize disruption to your landscaping and daily routine. We’ll provide a detailed timeline during your consultation based on your specific property conditions.

The investment in time pays off with decades of protection. Unlike interior solutions that manage water after it’s already penetrated, exterior membranes stop water infiltration at the source.

East Hills’ soil composition requires membranes that can handle significant hydrostatic pressure and Long Island’s freeze-thaw cycles. Polymer-modified systems and specialized sheet membranes are typically most effective for local conditions.

The soil around East Hills properties retains water due to the area’s generous landscaping and irrigation. This creates persistent pressure against foundation walls that standard dampproofing can’t handle. Professional-grade membranes are designed to create an impermeable barrier that withstands this pressure.

We select the specific membrane type based on your property’s soil conditions, foundation material, and exposure levels. We’ve worked with East Hills properties for over 25 years and understand which systems perform best in local conditions.

Exterior foundation waterproofing in Nassau County typically ranges from $121 to $171 per linear foot, with total project costs varying based on foundation size and specific conditions. Most East Hills homeowners invest between $8,000 and $15,000 for complete exterior membrane systems.

The cost depends on several factors including foundation height, soil conditions, accessibility, and whether additional drainage work is needed. East Hills properties with extensive landscaping or challenging access may require additional planning but the investment protects your home’s value long-term.

We provide detailed estimates that break down all costs upfront. There are no surprises or hidden fees. We also offer financing options to make the investment more manageable while protecting your home immediately.

Professional installation minimizes landscaping disruption through careful planning and proper excavation techniques. We work to preserve existing landscaping where possible and provide guidance on restoration after the waterproofing is complete.

The excavation process requires accessing your foundation walls, which means some landscaping impact is unavoidable. However, we use proper equipment and techniques to minimize the affected area and protect valuable plants and hardscaping where possible.

Most East Hills homeowners find that the temporary landscaping disruption is worthwhile for the permanent foundation protection they receive. We can coordinate with local landscapers for restoration work and provide recommendations for proper grading to support the waterproofing system.

Quality exterior waterproofing membranes installed by professionals typically last 20-30 years or more when properly installed and maintained. The lifespan depends on the membrane type, installation quality, and local soil conditions.

East Hills’ challenging soil conditions and seasonal weather patterns require durable membrane systems. Professional-grade materials are designed to withstand hydrostatic pressure, freeze-thaw cycles, and soil chemicals that can degrade lesser materials over time.

We back our exterior membrane installations with comprehensive warranties that provide peace of mind. We use proven materials from established manufacturers and follow strict installation protocols to ensure maximum lifespan and performance.

Exterior waterproofing is generally the most effective solution because it stops water before it reaches your foundation walls. This prevents the structural issues and indoor air quality problems that can develop when water penetrates the foundation.

Interior systems manage water after it’s already entered, which means your foundation walls are still exposed to moisture and hydrostatic pressure. While interior solutions cost less upfront, exterior waterproofing provides more comprehensive protection and often proves more cost-effective long-term.

For East Hills properties dealing with significant water intrusion or where foundation protection is the priority, exterior membranes offer the most reliable solution. We can assess your specific situation and recommend the approach that best fits your needs and budget.
