"This was a fairly extensive project. My backyard was nothing but weeds and rocks and dirt, in pits and valleys. I wanted a green lawn, and different levels, separated by a wall. I picked Pierce because he was well reviewed, and he didn’t try to upsell me. “You don’t need a retaining wall” he said, just stairs. When I was considering mulch rather than seed he said a similar thing “I don’t even think mulch will work with all the thistle you have.” I found Pierce to be very knowledgeable in addressing issues that came up throughout the project, and very efficient. I checked him on the cost of each phase of the project, and I always found his number reasonable. He is a bit of a perfectionist - he wants things done the right way. But the result has been worth it. I now have a beautiful lawn and steps where before there was nothing. He has even followed up with me several times since to check on how the lawn is progressing. I am very satisfied."

"Alex with Diaz Fencing was very punctual and easy to work and communicate with. He came out for the consultation and knew exactly what would be best for our yard. We had been trying to figure out how to do the project ourself for a year since buying our home, but we had a pretty steep decline in the back of our property that would cause the fence to be un level if not fixed properly. Alex suggested doing a retaining wall, and did so in a very cost effective yet still safe and great looking way. He even added solar lights to the decorative steps he created as a bonus without mentioning it. We also asked him to remove an old section of fence and build a decorative gate which he did at no extra cost and made look great. Diaz Fencing also got the work done fast! They completed our retaining wall in a day, and then completed the entire fence project the next. I 100% recommend Diaz Fencing for your fencing project, and am looking to hire them again for more projects to come!"

"Alex and his crew did a beautiful job on our existing deck floor. They were professional and courteous. I would have given them a Five Star Rating, but my contract also included installing one window shutter which had to be special ordered. Our deck floor was completed and the final payment was paid before the window shutter arrived. I called Southside Construction several times for someone to come back to hang my window shutter and complete the contract, but to no avail."

"Mervin and his crew created a space for us that is beyond our expectations. We live in a townhome with a very small patio which was rarely used. It has been transformed into a true outdoor oasis that we are now enjoying daily. The work was done with great care and all aspects of the job were handled professionally and thoroughly. We highly recommend Keystone Outdoor Oasis for any hardscaping project."

"Paul and Shaquana were great to work with to replace a portion of our sidewalk. Took a little longer than expected, due to an issue with the county that was out of their control. But they communicated well and completed the job with high quality. Would definitely recommend and use them again."

Retaining Wall Installers questions, answered by experts

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

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.

Proper design and construction prevent erosion and add structural stability to landscapes.

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.

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.
