French Drain Installation Services in Normandy Park

Is your yard turning into a mini lake every rainy season? It’s time to retire the ineffective “bag of holes” method and invest in a proper drainage solution. Our team specializes in creating well-graded systems that effectively channel water away from your property, tackling the unique challenges posed by Normandy Park’s clay soil.


What’s the Problem?

Water woes? You’re not alone! Here’s what we frequently encounter:

  • Standing water in your lawn or side yard that lingers long after a rain.
  • Mushy paths and ruts formed by foot traffic, pets, or trash bins.
  • Downspouts pouring water directly beside your foundation, risking leaks.
  • Slopes weeping across walkways and stairs after every storm.
  • Previous drainage solutions that were merely fabric and gravel—resulting in frustration!

What We Install (and Why It Works)

We offer a variety of drainage solutions tailored to fit your property’s needs:

  • French Drains: Perforated pipes nestled in gravel trenches designed to catch and redirect groundwater before it can cause damage.
  • Downspout Conveyance Systems: Solid pipes that safely transport roof runoff well away from your foundation.
  • Dry Wells & Dispersion Trenches: Perfect for areas where water cannot flow to the surface; expertly sized for your roof and soil type to handle the flow.
  • Channel Drains & Trench Grates: These nifty devices capture water on hardscaped areas and seamlessly blend into your landscape.
  • Cleanouts & Inspection Ports: Strategically placed for easy maintenance access—keeping your system running smoothly.

We believe in quality over quantity. Forget about just throwing fabric and gravel in the ground; our methods ensure your drainage works effectively and efficiently!


Our Build Method (No Shortcuts Here!)

  1. Site Assessment & Elevation Analysis: We use cutting-edge laser levels to map out water paths and soil types, ensuring the right design for your property.
  2. Utility Locate: Safety first! We always call 811 before digging to avoid any underground surprises.
  3. Trench & Line Creation: Trenches typically 8–12” wide and 18–24” deep, lined with non-woven geotextile to enhance drainage.
  4. Base Course Layer: We add 3–4” of ¾” clean drain rock before placing the pipe, ensuring optimal flow.
  5. Pipe Installation & Slope Adjustment: Our perforated pipe is set with holes facing down at a ~1% fall (about ⅛” per foot) for perfect drainage, while downspouts utilize solid pipe.
  6. Rock Envelope: A clean, angular rock bed fills up to 2–3” from grade, ensuring your system stays intact.
  7. Wrap & Cap: We fold the fabric over to keep out dirt, then top with soil, sod, mulch, or decorative rock to keep your yard looking sharp.
  8. Outlet Installation: We daylight to the curb or steep lawn where permitted or set up appropriately sized dry wells/dispersion systems in accordance with local codes.
  9. Proofing: We conduct a hose test and document the slope and cleanouts before backfilling so you have peace of mind.

Remember, connecting your drains to a sanitary sewer is a hard no in our book. We make sure your outlet is compliant and effective!


French Drain vs. “Pipe in a Trench” (Here’s Why Yours Failed)

  • No Slope = No Flow.
  • Fabric in the Wrong Place = Mud Filter.
  • Round Rock rolls; Clean Angular Rock locks and drains.
  • Perforated Under Roof Water = Sludge. Keep Downspouts on Solid Pipe.
  • No Cleanouts = No Maintenance.

Quick Sizing Math (For Easy Ordering)

  • Trench Volume per Linear Foot
    • 8” wide × 12” deep = 0.67 cu ft/LF → ~40 LF per cubic yard
    • 12” wide × 18” deep = 1.5 cu ft/LF → ~18 LF per cubic yard
  • Rock: Order 10–15% extra for settlement/voids.
  • Pipe: Add 10–20% for bends and cleanouts.

Best Places to Install French Drains

  • Along Uphill Property Lines to intercept runoff from neighboring properties.
  • Behind Retaining Walls with dedicated drainage solutions.
  • Across Soggy Lawns to lead excess water to a dry well or dispersion trench.
  • Adjacent to Walks/Steps that tend to weep during the rainy months.

Our Annual Maintenance Plan (Keep Your Yard Healthy)

Our maintenance plan ensures your yard remains vibrant and healthy:

  • Cleanout Checks: We open caps, flush, and confirm flow after the first big fall storm.
  • Leaf Control: We manage gutter health and install inlet screens to keep organic debris out of the system.
  • Outlet Inspection: We clear splash zones and daylight ends, plus test dry wells to ensure they’re functioning.
  • Surface Refresh: We top off mulch or rock as needed after settling.
  • Photo Log: We provide before-and-after photos so you can visually track the improvements!

We’re all about low-maintenance landscaping! Our mission: fewer puddles between visits and less hassle for you.


Service Cadences (Choose What Works for You)

  • Quarterly: Focused on fall storm prep, winter/spring checks, and summer tune-ups.
  • Bi-Monthly: Ideal for properties with high leaf fall, heavy water flow, or complex drainage systems.

What’s Included in Annual Maintenance

  • Open/flush cleanouts; check for buildup of fines.
  • Inspect outlet daylight/dry well and remove any debris.
  • Gutter/downspout checks and screen installations (if missing).
  • Grade touch-ups over trenches; we’ll reseed or remulch as needed.
  • A straightforward report with recommendations for any capacity increases.

Why Annual Maintenance Matters

  • Prevents Clogs before storm season hits.
  • Protects Foundations & Pathways from saturation and heaving.
  • Extends System Life: Clean rock and open outlets mean fewer callbacks.
  • Saves Money: Regular maintenance is far more cost-effective than expensive excavation!

How It Works

  2. Installation Day(s): We manage trenching, rock, pipe, cleanouts, outlet installation, proof testing, and tidy backfill.
