Myth #1: “French drains eliminate all water problems”
Fact:
French drains manage groundwater, but they do not fix:
Roof runoff issues
Surface grading problems
Plumbing leaks
Structural cracks
High water tables on their own

Drainage systems manage subsurface water but must be paired with grading and moisture control.Building Science Corporation (2021–2024)
Water problems require source control, not single-solution fixes.
Myth #2: “If there’s water, you always need a French drain”
Fact:
Not every moisture issue requires a drain.
Standing water can be caused by:
Poor exterior grading
Downspouts dumping at the foundation
Clogged or missing gutters
Condensation, not groundwater
High humidity in crawl spaces
Installing a drain without identifying the source often leads to unnecessary cost and disappointment.

Requires water source management, not default drainage installation.
Myth #3: “Interior French drains cause mold or odors”
Fact:
French drains do not create mold or odors.
Odors and mold occur when:
Water is not properly discharged
Soil remains saturated
Humidity is not controlled
Drainage is installed without air sealing or vapor control
Drains manage water — humidity management prevents odors.

Mold is caused by moisture and humidity, not drainage systems.ASHRAE 160 (2021–2023)
Humidity control is essential to prevent microbial growth.
How French Drains Work
French drains are trench-based drainage systems designed to redirect water away from vulnerable areas like crawl spaces, foundations, and yards. These systems consist of a perforated pipe placed in a gravel-filled trench, which collects and channels groundwater or surface runoff safely away from your home.
- Exterior French Drains: Installed outside the foundation to intercept surface water and prevent it from reaching your crawl space.
- Interior French Drains: Installed along the interior perimeter of the crawl space or basement, capturing incoming water and directing it to a sump pump system for removal.
Key Benefits
- Reduces moisture and humidity levels beneath your home
- Prevents mold growth, wood rot, and structural weakening
- Protects foundations and keeps crawl spaces dry
- Improves long-term air quality and energy efficiency
Our Process
1. Site Assessment – We begin with a detailed inspection to determine water entry points and drainage needs.
2. Trench Installation – Trenches are dug with care to avoid utilities and landscaped areas.
3. Drain Placement – A perforated drain pipe is laid in gravel and lined with fabric to prevent clogging.
4. Connection to Sump Pump or Outlet – Interior systems are linked to sump pumps; exterior systems drain away from the structure.
