What to Expect from a Drainage Install: A Homeowners Guide

Return to Blogs

Written on:

When your yard turns into a swamp after a heavy rain, it is more than just an eyesore—it can threaten your foundation, damage landscaping, and lower property value. With recent storms in Middle Tennessee dropping record rainfall, more homeowners are reaching out for professional help. If you are wondering what happens during a drainage installation project, this blog will walk you through it—step by step.

At Excavation Contractors LLC, we help homeowners in Brentwood, Franklin, Spring Hill, and surrounding areas protect their yards and homes with effective, affordable drainage solutions. Here’s what to expect when you schedule a drainage installation with us:

1. Initial Consultation and Site Evaluation

Every successful project starts with a detailed evaluation. We’ll walk your property with you, ask about problem areas, and identify how water is moving—or not moving—through your yard.

Using professional tools like laser levels we assess:

    • Low spots where water collects

    • Areas of erosion or muddy soil

    • Gutter and downspout discharge zones

    • Slopes and how they affect runoff

This gives us the information we need to design a drainage solution that fits your yard—not someone else’s.

2. Designing the Right Solution

Not all drainage problems require the same fix. We’ll tailor a plan based on your yard’s slope, soil type, and problem areas. Some of the most common solutions include:

  • French drains for subsurface water (and surface water if done properly)
  • Swales to redirect surface runoff

  • Grading to slope water away from the foundation

  • Downspout extensions to keep water away from your home

We believe in using the simplest, most cost-effective option that actually works.

3. Permits and Planning (If Needed)

For most residential drainage projects, permits aren’t required—but in some cases (like connecting to a city storm drain or working near utility easements), we have the knowledge of what to do and where to start.

We also monitor the weather and schedule your project accordingly, so we are not digging in soaked soil or rushing installation before a storm.

4. The Installation Process: Step by Step

Here is what typically happens once we begin work:

    • Marking out the drainage layout and calling 811 to locate utilities

    • Excavating trenches or reshaping the yard’s grade

    • Installing perforated pipes, catch basins, gravel, filter fabric, or sod

    • Backfilling and final grading

    • Cleaning up and restoring disturbed areas with erosion prevention measures

Our crew works quickly and efficiently—most drainage projects are completed in 1–3 days.

5. Temporary Disruptions

You may lose access to parts of your yard temporarily while we work. We do our best to minimize damage to existing landscaping and always clean up at the end. If you have pets, garden beds, or sensitive areas, we’ll plan around them.

Also note the time of year you are conducting your drainage operations. One heavy storm in the spring time could push the installation back weeks due to saturated soil.

6. Final Walkthrough and Maintenance Tips

Before we leave, we will walk you through your new system and explain how it works. We will also share simple maintenance tips like:

    • Clearing debris from catch basins or inlet grates

    • Avoiding heavy traffic over French drain areas

    • Watching how water flows during future rains

Cost Expectations

Costs vary depending on project size and complexity, but here are some general price ranges:

    • Grading only: $1,500–$3,000+

    • French drain systems: $2,500–$8,000+

    • Swales or dry creek beds: $1,500–$5,000+

    • Downspout extensions: $1,500–$3,500+

Why Local Experience Matters

Tennessee’s unique mix of red clay, hills, springs, and sudden downpours make proper drainage a challenge. That is why it’s important to hire a local expert who understands the terrain, soil, and water flow patterns specific to our region.

At Excavation Contractors LLC, we have helped homeowners from Brentwood, Franklin, and Spring Hill protect their yards, foundations, and homes from water damage—without overcharging or overcomplicating the process.
