Trusted Inwood French Drain Contractors
We’ve been protecting Inwood homes from water intrusion for over 25 years. We understand how older homes in this area behave when water finds its way inside.
Many homes here were built in the 1940s and 1950s, and we’ve seen exactly what happens when aging drainage systems fail. We know which foundation types are most vulnerable and how Inwood’s soil conditions affect water movement around your home.
Our team has completed over 500 projects with more than 150 satisfied customers who no longer worry when storms hit. We don’t just install drains – we solve the root cause of your water problem so it doesn’t come back.
French Drain System Installation Process
We start with a thorough inspection to identify exactly where water enters your basement and why. This isn’t a quick walkthrough – we examine foundation walls, floor joints, window wells, and exterior drainage patterns around your home.
Next, we explain what we found in plain language so you understand the root cause and why our recommended solution works long-term. Most interior French drain installations in Inwood take just 1-2 days to complete.
We excavate a trench around your basement perimeter, install perforated drainage pipe surrounded by gravel, and connect everything to a sump pump system. 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.

Complete French Drain Solutions Inwood
Interior French drain systems cost half as much as exterior installations and install without disrupting your landscaping or daily routine. For Inwood homes, interior systems offer superior protection because they’re not buried in several feet of dirt where they can clog with roots and debris.
The perforated pipe collects groundwater before it reaches your basement floor, channeling it to a designated drainage area or sump pump. We use proper gravel size and type to ensure optimal water flow and long-term performance.
Many Inwood homeowners benefit from our combination approach – sealing interior walls while improving exterior drainage around problem areas. Most residents invest between $3,000 and $15,000 for complete basement waterproofing, though costs vary based on basement size and water intrusion severity. We provide detailed estimates after inspecting your specific situation.
How much does French drain installation cost in Inwood in 2026?
French drain installation costs in Inwood typically range from $3,000 to $15,000 for complete basement waterproofing, depending on your basement size and the severity of water intrusion. Interior French drain systems cost about half as much as exterior installations.
The final price depends on several factors: how many linear feet of drainage you need, whether you require a sump pump system, and if additional waterproofing measures are necessary. We provide detailed written estimates after inspecting your specific water problem, so you know exactly what you’re paying for and why each component is necessary.
How long does it take to install a French drain system?
Most interior French drain installations in Inwood take just 1-2 days to complete. This includes excavating the perimeter trench, installing the perforated pipe and gravel, connecting to the sump pump system, and restoring your concrete floor.
Exterior installations take much longer – often several days due to extensive excavation around your home’s perimeter. Interior systems are faster because we’re working in a controlled environment without weather delays or landscape restoration requirements.
The timeline can vary slightly based on basement size and any unexpected conditions we discover, but we’ll give you an accurate schedule during our initial inspection.
What size gravel and pipe should I use for a French drain?
We use 3/4-inch washed gravel for optimal water flow and perforated pipe that’s properly sized for your specific drainage needs. The gravel size is critical – too small and it clogs with sediment, too large and water doesn’t flow efficiently through the system.
The perforated pipe gets positioned at the proper slope (typically one inch drop per eight feet) to ensure water moves toward your sump pump or drainage outlet. We surround the pipe completely with gravel to create a water collection zone that feeds into the drainage system.
These specifications matter because improper materials or installation can cause your French drain to fail within a few years. We use proven materials and techniques that keep working for decades.
Can I build a French drain in my yard myself?
While it’s possible to install a basic yard drainage system yourself, basement French drains require professional installation to work properly long-term. Basement systems need precise grading, proper connection to sump pumps, and waterproof concrete restoration.
DIY installations often fail because of incorrect pipe slope, inadequate gravel coverage, or poor connections to existing drainage systems. When a basement French drain fails, you’re dealing with water damage, mold problems, and expensive repairs.
For surface water issues in your yard, a simple French drain might work as a DIY project. But for basement protection, professional installation ensures you get a system that actually keeps your basement dry for decades, not just a few seasons.
Do interior or exterior French drains work better in Inwood?
Interior French drain systems work better for most Inwood homes because they’re protected from the elements and easier to maintain. Exterior systems buried in several feet of dirt eventually clog with roots, sediment, and debris, especially in our local soil conditions.
Interior systems collect water before it reaches your basement floor, and since they’re accessible, any maintenance or repairs are straightforward. They also cost half as much as exterior installations and install without disrupting your landscaping.
For existing homes in Inwood, interior French drains offer the best combination of effectiveness, cost, and convenience. Exterior systems might make sense for new construction, but for established homes with water problems, interior solutions deliver better long-term results.
How do I know if I need a French drain system?
You need a French drain system if you notice recurring water problems in your basement – puddles after rain, damp spots that never dry, water stains on walls, or musty odors that indicate moisture buildup. These signs usually mean groundwater pressure is forcing water through your foundation.
Many Inwood homeowners ignore small water issues thinking they’ll go away, but basement water problems almost always get worse over time. Standing water signals an ongoing drainage or groundwater pressure problem that won’t resolve itself.
If you see any signs of basement moisture, it’s worth having a professional inspection. We can determine whether a French drain system is the right solution or if other waterproofing measures would work better for your specific situation.
