If your yard is losing ground to erosion, a sloped lawn is eating into your usable space, or water is pooling where it shouldn’t, a properly engineered retaining wall is often the fix. Retaining walls in Evanston, IL are not a one-size-fits-all project — the right design depends on your soil, your slope, your drainage situation, and yes, how cold it gets. JWD Landscaping & Outdoor Living has been building retaining walls for Chicago-area homeowners since 2016, and we design every one with the region’s brutal freeze-thaw cycles in mind.
What to Expect From a Retaining Wall Project
Every retaining wall project starts the same way: with the ground underneath. Before any block gets set or stone gets placed, the soil conditions, slope grade, drainage patterns, and how much load the wall needs to hold all have to be understood. Naperville’s clay-heavy soil and the region’s freeze-thaw cycles put real pressure on poorly built walls — heaving, leaning, and cracking are common failures when installation shortcuts are taken.
A proper installation includes excavation, a compacted gravel base, and — depending on wall height and design — drainage aggregate behind the wall to relieve hydrostatic pressure. For walls over a certain height, Naperville’s building codes may require a permit and engineered drawings.
Materials commonly used for retaining walls in Naperville include:
- Segmental concrete block (sometimes called Allan Block or Versa-Lok style) – the most popular choice for residential walls. Interlocking, structurally reliable, and available in a wide range of textures and colors.
- Natural stone – fieldstone or cut stone walls offer a more organic, traditional look. They take more labor to build correctly but age beautifully.
- Boulder walls – large-scale boulders work well for steeper slopes and give a naturalistic feel that fits oversized suburban lots.
- Brick – less common for structural walls but used where the aesthetic matches an existing home exterior.
Timeline depends on wall size and site conditions. A straightforward single-tier wall can often be completed in a few days. Complex multi-tier systems or walls requiring drainage work take longer.
Who Is a Good Candidate for a Retaining Wall?
You don’t need a dramatic hillside to need a retaining wall. In Naperville, some of the most common situations where retaining walls make a real difference include:
- Sloped backyards – where lawn mowing is difficult and usable flat space is limited
- Erosion along property edges , especially near driveways, walkways, or fences where soil washes away during heavy rain
- Grade changes near the foundation where water tends to pool or run toward the house
- Terraced landscaping where the goal is to create multiple levels of planting beds or lawn areas
- Drainage problem areas where redirecting water flow requires reshaping the grade
Retaining walls are also increasingly popular as seating walls — lower, capped walls built along a patio perimeter that double as informal seating for outdoor gatherings. If you’re adding a patio or outdoor kitchen, a seating wall often makes sense as part of the same project.
What Evanston Properties Are Up Against
Evanston sits on glacial lake plain soil — it drains slowly, shifts with moisture changes, and does not forgive a wall built without proper footing or drainage behind it. Add in winters that push temperatures well below freezing and springs that send standing water across every low spot in the yard, and you have conditions that expose every shortcut a contractor took.
That is why so many retaining walls fail within five to ten years: they were built with the right materials but the wrong design for this specific soil and climate. A wall without adequate drainage behind it will push forward under hydrostatic pressure. A wall without a compacted base will settle and tip. A wall built too shallow will heave in the first hard freeze.
We design around these failure points from the start — proper batter, drainage aggregate, base depth, and geogrid reinforcement where the height requires it.
What to Expect From Retaining Wall Installation
The process starts with a free on-site consultation. We look at the slope, the soil, the drainage patterns, and what you want the space to do when the wall is done. That last part matters: a retaining wall is not just structural, it is one of the most effective ways to turn a difficult slope into usable outdoor living space — a flat patio area, a terraced garden, a defined edge along a driveway or walkway.
From there, we handle design, material selection, any necessary permitting, and full installation. Here is what the typical project sequence looks like:
- Site assessment and design — We measure, evaluate drainage, and map out the wall layout before anything gets quoted. You know exactly what you are getting before work begins.
- Excavation and base preparation — The foundation of any retaining wall is what you cannot see. We excavate to the correct depth, compact the base, and set the first course level before the first block or stone goes in.
- Wall construction — Whether you choose segmental concrete block, natural stone, or another material, each course is set for structural stability, not just appearance.
- Drainage installation — Drainage aggregate and perforated pipe are installed behind the wall to prevent hydrostatic pressure from building up and pushing the wall forward.
- Finishing and cleanup — Final grading, backfill, and cleanup bring the project to a close. If the retaining wall is part of a larger project — a patio, walkway, or landscape redesign — we sequence the work so it all comes together cleanly.
Most residential retaining wall projects in Evanston take between two and five days depending on length, height, and site conditions.
Who Is a Good Candidate for a Retaining Wall?
Not every sloped yard needs a retaining wall, but if any of these describe your property, it is worth a conversation:
– You have a slope that is actively eroding — bare soil, exposed roots, or material washing onto hardscape or into the street after rain.
– Your yard drops sharply enough that usable flat space is limited and you want to reclaim it.
– You have water drainage problems where runoff from a slope is moving toward your foundation, garage, or a neighboring property.
– You want to define outdoor living areas — separating a lower patio from an upper lawn, or creating terraced planting beds on a hillside.
– You have an existing wall that is leaning, cracking, or bowing and needs to be rebuilt correctly.
Evanston’s older residential neighborhoods include a lot of properties with mature landscaping and established slopes. If your retaining wall was built more than 20 years ago and has not been assessed, it may be working harder than it looks.
Why JWD Landscaping & Outdoor Living?
JWD is a locally owned contractor that has been working in Chicago and the surrounding suburbs — including Evanston — since 2016. We are fully licensed and insured, and every project starts with a free consultation.
A few things that set how we work apart:
- We design for this climate specifically – Chicago’s freeze-thaw cycle is not a footnote — it is a core engineering constraint. Every wall we build is designed for it: base depth, drainage, batter, and reinforcement are all sized for conditions here, not copied from a generic spec sheet.
- We handle complete outdoor environments – A retaining wall rarely exists in isolation. If your project involves a patio, drainage work, a walkway, or a landscape redesign, we can handle all of it. That means no coordination gaps between contractors, and a finished yard that was designed as a whole.
- Personalized design, not a catalog – We do not show you a single product line and tell you to pick a color. We work through materials, layout, and scale with you — accounting for what your property needs structurally and what it should look like when the project is done.
- Responsiveness – We hear consistently that homeowners find contractors who go quiet after the initial estimate frustrating. We stay in contact throughout the project.

Frequently Asked Questions About Retaining Walls in Evanston, IL
What materials are best for retaining walls in Evanston's climate?
For most residential projects in Evanston, segmental concrete block and natural stone are the most durable choices. Concrete block systems are engineered for interlocking strength and hold up well through freeze-thaw cycles when properly installed with drainage. Natural stone offers a more traditional aesthetic and is extremely durable, though it typically requires more skilled labor. Timber walls are less expensive upfront but degrade faster in this climate and are generally not recommended for walls over three feet or in areas with significant moisture. The right choice depends on your budget, site conditions, and the look you want.
How much does retaining wall installation cost in Evanston?
We do not publish flat rates because retaining wall costs vary significantly based on wall length, height, material, site access, drainage requirements, and whether any permit work is needed. The best way to get an accurate number is through an on-site consultation, which is free. We provide detailed quotes so you know exactly what is included before any work begins.
How long do retaining walls last, and what maintenance do they need?
A well-built retaining wall with proper drainage can last 25 to 50 years or longer depending on the material and site conditions. Concrete block and stone walls require very little maintenance beyond periodic inspection — checking for any shifting, bowing, or drainage issues after major weather events. You should also keep vegetation cleared from the base and watch for signs that drainage behind the wall is backing up. Addressing small problems early prevents the kind of structural damage that requires a full rebuild.
Do I need a permit to build a retaining wall in Evanston?
Generally, yes — Evanston requires a permit for retaining walls over a certain height, typically four feet. Some walls may also require engineering documentation depending on height and load. Permit requirements exist for good reason: an improperly built wall can fail in a way that damages neighboring property. We are familiar with the permit process for projects in Evanston and can help navigate what your specific project requires.
How long does a retaining wall installation typically take?
Most residential retaining wall projects take between two and five days on-site. Longer walls, multi-tier designs, or projects that include additional hardscaping or landscaping will take longer. Permit approval, if required, adds time before construction begins — typically one to three weeks depending on the municipality. We give you a realistic timeline during the consultation so you can plan accordingly.
