"Rich did a great job with our garden design and follow-through. I had originally wanted to just get a quote for budgeting purposes but decided to accept his quote to do the garden install in the fall. He was very conscientious about early frost and had made a visit to apply some spray to reduce the impact of frost in late fall. He then made a trip up in the spring to check on the status of our plants to see if any plants needed to be replaced. I also had a problem with ferns growing out of control. Rich installed a barrier to keep the ferns within the area we wanted it to stay. All in all, I am very happy with what he has done and expect to use his services more in the future."

"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

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.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

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.

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.

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.
