Stop Water Before It Becomes a Bigger Problem
When water keeps pooling in your yard or finding its way into your basement, the issue is usually not the weather. It is the drainage around your home. At United Waterproofing, we provide professional French drain installation in CT and Westchester County, NY to help homeowners control groundwater, protect their foundation, and keep lower levels dry.
As an experienced French drain contractor, we install interior French drains, exterior French drains, and full foundation drainage systems built for the way local homes handle water. No matter if you are dealing with seepage, storm runoff, or repeated flooding, we design a solution that addresses the source.
A drainage problem usually shows itself in more than one way. You may need a French drain if you notice:
These warning signs often point to poor drainage around the home. The sooner the issue is addressed, the easier it is to protect your foundation and finished space.
Every property drains differently. That is why we offer more than one type of French drain installation. We evaluate the water source, soil conditions, foundation type, and grading before recommending the right system.
An interior French drain is installed along the inside perimeter of the basement floor. It collects water before it spreads across the slab and channels it into a sump pump or discharge system. This is often the right choice when:
Interior systems are a strong option for many Connecticut and New York homes, especially older foundations that were not built with modern drainage in mind.
An exterior French drain is installed outside the foundation near the footing. It intercepts groundwater before it reaches the basement walls, helping reduce pressure against the foundation. This system is often recommended when:
Exterior drainage can be combined with other waterproofing measures for stronger long-term protection.
Some homes need both interior and exterior drainage working together. A full foundation drainage system is often the best solution for properties with repeated water intrusion, poor soil drainage, or high water tables.
This approach helps create a more complete barrier against moisture, making it a smart option for homes across CT and Westchester County, NY, where water management around the foundation is a recurring concern.
We keep the process straightforward and focused on results.
We identify where water is entering, where it is collecting, and what is causing the drainage problem.
We design a system based on your foundation, yard grading, soil conditions, and water flow.
We install the French drain using quality piping, drainage stone, and filter fabric, then connect it to the proper discharge point or sump system.
We test the system to make sure water moves correctly and the drainage path is working as intended.
We leave the site clean and complete the restoration as part of the job. Our goal is to deliver a drainage system that works the way it should and holds up over time.
Homeowners call us because they want more than a quick fix. They want a contractor who understands how to solve the water problem at its source.
We do not guess, and we do not take a one-size-fits-all approach. We inspect the conditions, explain the options, and install the system that makes the most sense for your home.

If you need a basement French drain in CT or Westchester County, NY, United Waterproofing is ready to help. We install interior French drains, exterior French drains, and complete foundation drainage systems designed to protect your home for the long term.
Pricing depends on the type of system, the length of the drain, and the condition of the site. We provide a clear estimate after a free on-site assessment.
It depends on where the water is coming from. Interior systems help manage water already entering the basement, while exterior systems stop water before it reaches the foundation. Some homes need both.
Many interior systems can be installed in about one to two days. Exterior systems may take longer depending on excavation and site conditions.
Exterior drainage requires excavation, but we work carefully and restore the area once the system is installed and tested.
Yes. A properly designed French drain system can reduce seepage, lower moisture levels, and help keep the basement dry.
If you are seeing new pooling, damp basement walls, or constant sump pump activity, the system may need repair or replacement. We can inspect it and give you a direct answer.
