"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

Retaining Wall Installers questions, answered by experts

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

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.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.
