"Flintstone Hardscapes LLC removed an old rotten deck and framed and built a beautiful concrete patio in my back yard. The space was small and they had to remove part of a fence to get access. They were wonderful and even replaced the fence overnight so my dog could not run off. I highly suggest you give them a call at 503.837.9294 to get a quote for your next project."

"Jose and his crew tackled our project by transforming an area with slope and different levels by replacing a retaining wall, creating a patio area, and adding a difficult-to-build set of stairs to create an attractive usable outdoor space. Their attention to detail is impeccable. Easy to work with, punctual, and kept the work site clean throughout the process. Hope to work with them again and highly recommend to friends and neighbors."

"Mike and his team did an outstanding job. They were very professional and courteous, and finished major cement work in just a few days. When they were finished, you could not tell that work was done, they cleaned up every bit of debris. We will definitely hire him again for any of our construction needs."

Retaining Wall Installers FAQs, answered by experts

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

Even if you think you know how to build a retaining wall theoretically, doing the actual work is a completely different story. There are lots of nuances in building retaining walls, and the slightest oversight can compromise their integrity. Therefore, we recommend you hire a pro to build, repair, or replace retaining walls.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.
