How Much Does a Retaining Wall Cost?

Most DFW-area retaining walls run about $25 to $100+ per linear foot depending on material, height, and drainage — here's what typically drives the price.

Typical retaining wall costs by material

Retaining wall pricing is usually quoted per linear foot rather than a flat rate, since cost scales with how much wall you actually need. As a general market guide for the DFW area:

Wall material	Typical cost per linear foot
Standard concrete block (segmental), under 4 ft	$25 – $50
Brick veneer	$50 – $100+
Natural stone or premium engineered systems	$100 – $150+

What a retaining wall costs by height

A rough sense of total project cost on a standard 10-foot run of wall:

Taller walls cost more per foot as well as in total — they need more material and excavation, and past about 4 feet they almost always need engineering review. Real numbers vary with site access, soil conditions, and material choice, which is why we quote every wall after seeing the site.

Wall height	Typical cost, 10-ft run
2 feet tall	$700 – $1,300
4 feet tall	$1,400 – $2,600
6 feet tall	$2,100 – $3,900

Why drainage costs more here than the national average

North Texas sits on expansive clay soil with some of the highest shrink-swell potential in the country — it expands when wet and contracts when dry, which puts real pressure on a wall that isn't draining properly. Skipping drainage is one of the most common reasons a retaining wall bulges, leans, or fails within a few years instead of lasting decades.

A proper drainage system (gravel backfill, a perforated drain line, and a way to route water away from the wall) typically adds somewhere in the range of $10–$25 per linear foot. On DFW soil, we treat this as a required part of the build, not an optional upgrade — it's the difference between a wall that holds up through a normal wet spring and one that doesn't.

When engineering and permits come into play

Walls taller than about 4 feet typically need a structural engineer's stamped design to meet code and hold up safely over time — engineering review usually runs $500–$2,000+ depending on wall height and site complexity. Permits and inspections add another cost on top of that (commonly a few hundred dollars locally), and site conditions like slope, soil, and access can add further site-prep costs. Shorter walls under 4 feet usually don't require engineering, which is part of why they cost noticeably less per foot.

Getting an accurate estimate for your project

Because height, length, material, drainage needs, and site access all move the price independently, the ranges above are a starting point for research — not a quote. The only way to get an accurate number for your yard is a site evaluation, where we look at the slope, soil, drainage path, and access before pricing the wall. We build every retaining wall with proper drainage as standard, given how DFW clay behaves.

QUICK QUESTIONS

How much does it cost to build a retaining wall?

In the DFW area, most retaining walls run roughly $25–$100+ per linear foot depending on material and height, with a typical 4-foot wall costing more per foot than a 2-foot wall due to added material and drainage needs. A site visit is the only way to get an exact number for your yard.

How much do retaining walls cost per square foot?

On a per-square-foot basis (a common way contractors bid larger walls), typical retaining wall costs run about $35–$65 per square foot including materials and labor, with premium materials like natural stone running higher.

Are taller walls always more expensive per foot?

Generally yes — taller walls need more material and excavation, almost always need more robust drainage, and once a wall exceeds about 4 feet it typically requires engineering review, which adds cost that a shorter wall doesn't need.

Does drainage add significantly to the cost?

Yes, typically around $10–$25 per linear foot — and on DFW's expansive clay soil, we treat proper drainage as essential rather than optional, since poor drainage is one of the most common causes of wall failure here.

What's the cost difference between block, brick, and natural stone walls?

Standard concrete block is the most budget-friendly option (roughly $25–$50/linear foot locally), brick veneer costs more (roughly $50–$100+/linear foot) for a longer lifespan and different look, and natural stone or premium engineered systems run highest (roughly $100–$150+/linear foot), often used on taller or more visible walls.
