Example: a Versa-Lok wall 40 ft long and 4 ft high (160 sq ft of wall face) with easy machinery access is about $12,800 installed. The calculator shows a project range of about $11,520 to $14,080 for those inputs. Change the length, height, and access below to price your own wall.

A Versa-Lok block retaining wall built by Q&A Landscaping starts at $80 to $90 per square foot of wall face, installed. To find your wall's square footage, multiply its length by its height: a wall 10 feet long and 3 feet tall is 30 square feet. Every job has a $2,500 minimum.
That's the price of a finished wall, not a pallet of block. It covers the compacted stone base, the block, pins and caps, the drain pipe along the bottom of the wall, and the clean stone backfill behind it.

| Wall height | Easy access | Normal access | Complicated access |
|---|---|---|---|
| 2 ft | $80 | $85 | $100 |
| 3 ft | $80 | $85 | $100 |
| 4 ft | $80 | $85 | $100 |
| 5 ft | $80 | $85 | $100 |
| 6 ft | $80 | $85 | $100 |
The per-square-foot rate does not change with height, because height only changes how many square feet of face you are building. Taller walls cost more in total, and walls over about 4 feet usually need a permit and geogrid. Walls of 30 square feet or less add $10 per square foot. Every job has a $2,500 minimum, and walls over 200 square feet are priced per project.
| Wall height | Square feet | Easy access | Normal access | Complicated access |
|---|---|---|---|---|
| 2 ft | 80 | $6,400 | $6,800 | $8,000 |
| 3 ft | 120 | $9,600 | $10,200 | $12,000 |
| 4 ft | 160 | $12,800 | $13,600 | $16,000 |
| 5 ft | 200 | $16,000 | $17,000 | $20,000 |
| 6 ft | 240 | Priced per project (over 200 sq ft) | ||
Add $2,000 if the yard needs extensive grading and $4,000 if extra fill has to be brought in. Concrete footers, railroad ties, and difficult removals are priced at the site visit.
If you searched before landing here, you probably saw national cost sites quoting $15 to $50 per square foot. Those numbers average every kind of wall across the whole country, from small garden borders to do-it-yourself block, so they come in low.
A Pittsburgh retaining wall usually holds back a real hillside of heavy clay soil. Building one to last means a deep, well-compacted base, drainage behind the wall, and geogrid reinforcement on taller walls. That work is most of the cost, and it's the difference between a wall that stands for decades and one that bows out in a few winters.
The calculator above builds those factors into a ballpark range. Upload a few photos of your yard for a tighter number, or request a free on-site estimate for an exact price.

Versa-Lok is our go-to block for retaining walls. Here's why, and how we build with it.
Hilly terrains require structural support in order to keep soil in place so your landscape doesn’t slide forward and turn into a landslide.
A reinforced retaining wall can prevent this from happening while giving your yard an attractive focal point.
Retaining walls must be durable and long-lasting to keep your yard looking its best.
And selecting the right material and brand that's going to last for the long haul can be overwhelming if you’re just getting started.
Many landscaping experts like Q&A Landscaping opt for Versa-Lok segmental retaining wall units for the best results.
Versa-Lok blocks are the most structural and cost-effective option for retaining walls. They come in different colors allowing you to customize your wall and they are all generally the same price.
The blocks pin together and are very heavy, increasing the life span of your wall but they must be built correctly by a professional to get the most out of it.
We build retaining walls for our clients on a compacted stone base. Compaction is the most important part of the job.
Failure to thoroughly compact the base is devastating to the longevity and appearance of a Versa-Lok retaining wall. We own multiple types of compactors that are best for specific situations.
A drain is installed behind the wall along the bottom, and then we fill behind the wall with clean 2b limestone.
Most yards require soil reinforcement to prevent erosion. Because many Pittsburgh yards have soft soil, you should select your material wisely. Our team can assess your yard and determine if soil reinforcement is necessary for your retaining wall.
We utilize geogrid for retaining walls where applicable to increase the strength of the wall by anchoring the wall to the backfill behind it. The heavy-duty net-like fabric is laid between two rows of blocks and then stretched back into the hillside behind.
The fabric is then covered with the next lift of stone backfill and the process is repeated a few times per wall depending on the height of the wall. The weight of the soil behind the wall stops the wall from being able to bow out.
No two yards are alike, and blocks may need to be cut to accommodate your retaining wall’s design. You must have the right tools and be extremely careful when cutting blocks in order to prevent injury. It’s recommended to leave block cutting to the professionals. Our team is trained to precisely cut blocks to create a beautiful finish for your retaining wall.
We use a block cracker to cut blocks so they will have a finished rough face like the front of the block. Sometimes we will do the caps one shade darker than the wall block if a client is looking for a little more variation and unique design. We are also able to build under cap lighting into retaining walls if desired to elevate your landscape and add dimension.
Building a sturdy, attractive retaining wall that complements your yard is no easy task, especially if you are a novice landscaper. Getting your Versa-Lok retaining wall built by a professional is certainly an investment, but we can guarantee the end result will be much better than DIY and will last for years to come.
Choosing the right Pittsburgh landscaping team is crucial to ensure your retaining wall is built correctly and has the exact design that you want.
