Cost, response, and scope
What a retaining wall costs, and what happens after you send the form
- What does a retaining wall cost around Pittsburgh?
- National cost guides put an ordinary residential retaining wall at $3,500 to $9,400, with a national average of $6,300 (LawnStarter, updated December 2025), and installed cost at $35.41 to $48.62 per square foot for installed dry-stack block up to three feet above grade, before permit fees and general contractor overhead (Homewyse, May 2026). Those are national consumer guides, not government figures and not Pittsburgh figures.
- Why those numbers may not cover your wall
- They price an ordinary wall, roughly three to four feet. Pennsylvania adopts IRC R404.4 through the Uniform Construction Code, which requires an engineer-stamped design over 48 inches of unbalanced fill, or over 24 inches where the wall carries a surcharge such as a slope, driveway, or structure. On Pittsburgh hillsides that threshold is crossed often, and no published index prices an engineered hillside wall or a slope stabilization job. For that work the licensed contractor who stands in your yard is the only honest source of a number. Our cost guide walks through what moves it.
- How fast will someone get back to me?
- Your request reaches a licensed local contractor, usually within about an hour during the day. That contractor then contacts you to look at the wall and price the work on their own schedule.
- What work is covered?
- Failing and leaning wall repair, repair, hillside and slope stabilization, new installation, boulder walls, and drainage.
