"Great team. Great work! They delivered the materials on Friday afternoon and installed on Saturday. The job was about 3/4 of an acre replacement of our post & rail fence. I looked at 3 other companies but Diaz was a good price, made me feel like they knew what they were doing, and answered my calls/texts when I had questions."

"Patrick and his team were wonderful to work with for our stone and brick repointing! They came on time as scheduled for both the quote (which was very fair for the work that needed done) and actual work start date. The work they did looks amazing, and they took care to make the new sections of mortar have the same style as the old sections on our beautiful Victorian. Patrick even pointed out several other issues (some of which we were aware of), and prioritized them based on severity. We will happily be hiring them again for our masonry needs!"

"Gary Pieretti built a 32 foot retaining wall with pressure treated lumber. The wall turned out exactly how I envisioned it, at a reasonable cost. He was flexible and professional and left my property much better than he found it."

"Mike, Marc and their crew were great. They came on time and completed the job in 3 days. They cleaned up everyday. They did a really good job with the concrete and they paid attention to details to make sure everything looked perfect. They also took the time to answer any questions that I had. I would recommend them to my family and friends."

"They arrived very promptly, ready for work dressed in their company jackets with excellent leaf blowers. The .42 acre lot, with many trees, had not been raked all season. We have a Certified Wildlife Habitat property, and mulch the leaves ourselves to put in the beds. As we had asked, they used a tarp to move the ever-growing pile of very wet leaves (after 3 days of rain) to the area at the back of the property we had designated. It took them less than 2 hours, and the price was very reasonable, $55 less than the other landscaper we had engaged who never showed up. We are very pleased, and intend to call Brison through the year for our seasonal landscape chores, highly recommend."

Retaining Wall Installers FAQs, 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.

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.

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.

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.  

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.
