"It went very well. Didn’t take long. Was able to start a couple of days after getting estimate. Damian was very polite and the cost was definitely better than other competitors. I wish I could’ve given at least 4.5 stars if the site allowed. The only improvement I would say is to communicate about when the day has ended and when it will resume. Overall I would recommend them to friends/family."

Retaining Wall Installers questions, answered by experts

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.

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

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.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.
