We Build, Repair, and Replace Retaining Walls
We are your Oakland County retaining wall specialists!

Retaining walls are an excellent functional addition to any landscape, especially if your property has an existing slope.  Building a retaining wall allows you to reclaim lost space by carving out flat and usable outdoor spaces on sloping ground.  Retaining walls hold back earth and soil which helps to create new level areas for the construction of a new garden bed, a new lawn, a patio or an outdoor cooking area, a parking area, and more.  Retaining walls can be built using a variety of materials including rock, brick, block, boulders, or even wood.

Retaining Walls and Building Permits in Oakland County, Michigan

When building new retaining walls in Oakland County, there are a few important rules to know:

    • Walls over 36 inches tall usually require a building permit.
    • Engineered drawings may be needed if the wall must support heavy loads or structures.
    • Local city regulations can vary slightly, so it’s important to check requirements based on your location.

At Silva Custom Design, we handle the entire permitting process for you. We make sure your new retaining wall meets all local building codes and safety standards, giving you peace of mind and a project you can trust.

Here’s a cleaner, easier-to-read, and unique version of that section:

Proper Drainage for Retaining Walls

One of the leading causes of retaining wall failure is poor drainage. We’re often contacted by homeowners dealing with walls that are bulging, leaning, or collapsing — and in many cases, the original wall wasn’t built to handle water properly.

Retaining walls are designed to hold back soil, but they also trap water. Over time, water buildup behind the wall — known as hydrostatic pressure — creates powerful force. Combined with the weight of the soil, this pressure can push the wall outward, causing cracks, bowing, and even total failure.

To prevent these issues, proper drainage must be part of the wall’s construction. Depending on the materials and site conditions, we use solutions like:

    • Lateral drains or perforated pipe systems
    • French drains or weeping tile behind the wall
    • Blanket drains for larger walls
    • Free-draining granular backfill to reduce water retention

At Silva Custom Design, every new retaining wall we build is carefully engineered with the right drainage strategy to protect your investment and ensure long-term strength and stability.

Understanding Retaining Wall Surcharges

A surcharge is any extra weight placed on or behind a retaining wall — like a parked vehicle, a fence, or another structure. If your wall will support more than just soil, it must be built stronger to handle the load.

Examples of surcharges include:

    • Parking areas for boats, RVs, or vehicles
    • Fences or railings installed along the top of the wall
    • Tiered or multi-level retaining walls

When a surcharge is involved, we reinforce the wall using geo-grid — a material that adds strength by anchoring the wall into the ground behind it. Proper design and installation are critical to prevent buckling, shifting, or collapse over time.

    • Natural stone retaining walls
    • Large boulder retaining walls

What Does It Cost To Build Retaining Walls?

Retaining walls can vary in price depending on the size, scope, length, height, and the materials chosen.  Larger walls will need to be engineered which can add to the cost.

Smaller Garden Walls

$3,000 - $10,000

This would be for a small garden wall (under 2 feet high) to surround a small garden or to surround a small landscaping bed.

Medium Sized Walls

$10,000 - $30,000

This would be for a medium sized wall up to 4 feet high.  Installed with drainage and geo-grid so it lasts.

Large Retaining Walls

$30,000 - $100,000+

This would be a ballpark cost for a very large or tiered retaining wall or multiple wall with courses that are 4 feet or higher

Retaining Wall Projects Can Include

A beautiful retaining wall isn't just for looks.  They have an important job to do.  Whether we're building a brand new retaining wall or replacing an existing retaining wall that has failed, there are a number of things we do.

Proper Excavation
Proper Base Materials
Drainage Installation
Integrated Lighting
Built-in Stairs
Geogrid (for stability)
Cap Stones (for looks)
Engineering

These prices do not include stairs.  If you need stairs built within your retaining wall there will be an additional cost.  These price ranges are for a typical wall built using readily available landscape block.

These prices are ball park figures to give you a rough idea as to what you should expect.  If you need a firm price please request a consultation so we can view your potential project, listen to your ideas, and determine the actual scope of work required to complete your project.

Retaining Wall Repair Or Replacement

We specialize in rebuilding retaining walls that have failed and/or collapsed.

Retaining Wall Repairs

It's pretty common for us to get called out to repair an existing retaining wall that has collapsed or failed in some way.  This could be an old wood retaining wall that is rotting away or a block wall that is bulging or on the verge of collapse if it has not collapsed already.

Typically we don't recommend "repairing" retaining walls.  The wall has failed for a reason and that reason is typically poor construction or a poor choice of materials.  When a wall has failed we will usually recommend tearing the wall out and replacing it.  This would include demolition of the old wall, re-excavating the area to allow for proper base materials, installation of proper drainage, and proper backfill.  Building it right is the more cost effective option in most situations.

Rebuilding Failed Retaining Walls

If your existing retaining wall has failed and needs to be replaced it's usually more cost effective to demolish the old wall, remove the materials, re-excavate the site, install a proper base, geo-grid if necessary, install drainage, and build the retaining wall properly.

We specialize in rebuilding retaining walls that have failed and would be happy to provide you with a consultation if you have a wall that you believe needs to be replaced.

Edwin and his team were fantastic to work with! We needed our old 90's patio steps rebuilt the exact same way and they were the only company to tackle this project for us. All the others tried to talk us into a whole new look for a lot more money. So glad we went with Silva! Edwin's customer service and expertise is top notch. I highly recommend!

Loved working with Edwin and his team! His team redid our entire back yard and did a beautiful fence to go along with it! They also set up our playground/swing set for us! We loved them so much we had them come back the next year to fix up our garage and build us an above the garage room!

I HIGHLY recommend Silva custom design. Edwin is the best! Edwin redid my driveway and did the foundation + framing for my home addition. His crews were very respectful cleaning up daily and very hard workers! I honestly was sad he wasn’t able to do more work on my renovation.

Edwin and his team were fantastic to work with and our patio turned out beautiful. Edwin came out quickly to give us a quote on removing some raised beds and redoing our collapsing patio and then fit us into his schedule for the fall. We appreciated his professionalism and that he gave us quotes for both new pavers and reusing our old ones. We decided to go with new pavers and they look amazing. The work was done quickly and perfectly! We would happily recommend them to anyone.
