About French Drains
A French drain is a gravel-filled trench containing a perforated pipe that redirects surface water and groundwater away from problem areas. It's one of the most effective solutions for yards that hold water, foundations that stay wet, or low spots that never seem to dry out.
We install French drains that are designed for your specific property and drainage needs. The system collects water below the surface and channels it to a safe discharge point—whether that's a lower area of your yard, a storm drain, or a dry well.
French drains work quietly underground, protecting your foundation and keeping your yard usable. When installed correctly, they can last for decades with minimal maintenance.

Our Process
How we approach french drains projects from start to finish.
Assessment
We evaluate your property to understand where water is coming from, where it's collecting, and the best path to redirect it.
Planning
We design a drainage layout that addresses your specific problem, including trench depth, pipe sizing, and discharge location.
Excavation
We dig the drainage trench along the planned route, maintaining proper slope for water flow.
Installation
We lay the perforated pipe on a gravel bed, cover with more gravel, and add filter fabric to prevent sediment buildup.
Completion
We backfill the trench, restore the surface, and walk you through how the system works.
French Drains FAQs
Common questions about this service.
How deep does a French drain need to be?
Most residential French drains are installed 18 to 24 inches deep, but the exact depth depends on your specific situation—like how deep the water problem is and where the drain needs to outlet.
How long does a French drain last?
A properly installed French drain can last 30 to 40 years or more. The key factors are using quality materials, proper slope, and adequate gravel and filter fabric to prevent clogging.
Will a French drain fix my wet basement?
A French drain can help by redirecting water away from your foundation before it reaches your basement walls. For existing water inside, you may also need interior solutions. We can assess your situation and recommend the right approach.
How much does a French drain cost?
Cost varies based on the length of drain needed, soil conditions, and accessibility. We provide estimates after seeing your property so we can give you an accurate number for your specific project.
Do French drains work in clay soil?
Yes, but clay soil requires extra attention. We use more gravel and proper filter fabric to ensure water can reach the pipe. French drains are actually very effective in clay because the soil holds water instead of draining naturally.
