Basement Waterproofing Jericho NY
We’ve been protecting Jericho homes from water damage since 1998. We understand exactly what Long Island’s high water table and challenging soil conditions do to your basement.
Over 500 completed projects across Nassau County have taught us one thing: every Jericho home faces unique drainage challenges. That’s why we don’t use cookie-cutter solutions.
Your neighbors trust us because we show up when we say we will, finish on time, and back our work with warranties that mean something. We’ve seen what happens when French drain systems are installed wrong—and we’ve fixed plenty of them.
How French Drains Work Jericho
First, we excavate a trench around your basement’s perimeter, staying inside so your landscaping stays untouched. This typically takes one day for most Jericho homes.
Next, we install a perforated pipe system surrounded by the right gravel—¾” to 1½” washed river rock that won’t break down over time. The pipe collects water before it reaches your basement floor.
Then we connect everything to a sump pump that automatically removes collected water from your property. The entire system gets covered with high-strength concrete, restoring your basement floor to its original level.
You’ll never know the work was done—except for your newly dry basement that stays dry year-round.

French Drain Cost Jericho NY
Your French drain installation in Jericho, NY includes everything needed for permanent water protection. We use 4-inch perforated pipe designed specifically for Long Island’s soil conditions.
The system handles Jericho’s unique challenges—high groundwater from the Magothy and Lloyd Aquifers, seasonal water movement from spring snowmelt and summer storms, and the area’s mix of sandy and clay soils.
Installation typically costs between $40-$85 per linear foot for interior systems, significantly less than exterior alternatives that can run $3,000-$13,500 before landscape restoration. Most Jericho homes need 100-150 feet of drainage.
Your investment includes professional-grade materials, expert installation, comprehensive cleanup, and warranty protection that covers both parts and labor.
How much does French drain installation cost in Jericho, NY in 2026?
French drain installation cost in Jericho ranges from $40-$85 per linear foot for interior systems, which most homeowners prefer. For a typical home requiring 100-150 feet of drainage, expect to invest $4,000-$12,750.
Interior systems cost significantly less than exterior alternatives, which can run $30-$90 per linear foot plus landscape restoration costs. The total project cost depends on your basement’s size, soil conditions, and whether additional waterproofing measures are needed.
Most Jericho installations qualify for financing options, and the investment pays for itself by preventing costly water damage repairs that can easily exceed $10,000-$20,000.
What size gravel should I use for a French drain in Jericho?
The best gravel for French drains in Jericho is ¾” to 1½” washed river rock or granite chips. This size allows optimal water flow while preventing the system from clogging with Jericho’s sandy soil.
Avoid pea gravel—it’s too small and will clog quickly. Also avoid limestone or soft rocks that break down over time and restrict water flow. Hard, angular stones work best because they maintain their shape and create consistent drainage paths.
We source our gravel specifically for Long Island conditions. The right stone makes the difference between a French drain that works for decades versus one that fails within a few years.
How long does French drain installation take in Jericho homes?
Most French drain installations in Jericho take 1-2 days to complete. Interior systems install faster because we work inside your basement without excavating your yard or disrupting landscaping.
Day one involves excavating the perimeter trench, installing the perforated pipe system, and connecting to your sump pump. Day two covers backfilling with gravel, pouring new concrete, and final system testing.
Weather doesn’t affect interior installations, so we can work year-round. Exterior systems take longer (3-5 days) and depend on weather conditions, plus you’ll need additional time for landscape restoration.
Do I need a permit for French drain installation in Jericho?
Interior French drain installations in Jericho typically don’t require permits since they’re considered maintenance and repair work. However, exterior systems that alter drainage patterns may need Nassau County approval.
We handle all permit requirements when necessary and ensure installations meet local building codes. Our team knows Jericho’s specific regulations and works with Nassau County inspectors regularly.
If your project involves connecting to municipal storm drains or significantly altering your property’s drainage, permits become more likely. We’ll assess your specific situation during the initial consultation.
Will a French drain work with Jericho's high water table?
Yes, French drains work especially well in Jericho because of the high water table. The system intercepts groundwater before it reaches your basement floor, giving it a controlled path to your sump pump.
Jericho’s water comes from deep aquifers—the Magothy and Lloyd—which create consistent groundwater pressure. A properly installed French drain relieves this pressure by collecting water in the perforated pipe system.
The key is proper installation depth and grade. We install systems below your basement floor level, ensuring water flows toward the collection point rather than pooling around your foundation.
How do I build a French drain in my Jericho yard?
Building a French drain in your Jericho yard requires careful planning for Long Island’s soil conditions. Start by identifying where water pools and determining the best outlet location—typically a lower area where water can drain safely.
Dig a trench 12-18 inches wide and at least 18 inches deep, maintaining a 1% grade (1 foot drop per 100 feet). Line with landscape fabric, add 4-6 inches of ¾” gravel, install 4-inch perforated pipe, then cover with more gravel.
However, most Jericho homeowners find professional installation worth the investment. We have the equipment to dig properly, source the right materials, and ensure the system works with your property’s unique drainage patterns.
