"Ben not only replied immediately to my posting, but gave me a very reasonable quote based on the picture I had sent him of the damaged retaining wall. I suggested he might want to see the actual wall to make sure his price quote would stand, so he came over (on a Sunday!) and immediately said he could repair the wall right then! I am more than thrilled with the beautiful work he did and would hire him again for any type of stone work in the future."

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

"Excellent Work on My Fieldstone Foundation! I couldn't be happier with the work Four Seasons Foundation Repair did on my fieldstone foundation. They did a great job, and I'm extremely pleased with the results. Their workmanship and attention to detail really showed. It's not easy working with older fieldstone foundations, but they handled the job beautifully. I highly recommend Four Seasons Foundation Repair to anyone looking for quality foundation work. Thank you for a job well done!"

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"We unfortunately got scammed by a previous contractor in 2021 when we purchased our house in Elizabeth City. Our home reno paused for about a year until we met Thaad. He has been working with us through our whole home reno, he has done our living room, our bathroom, and has helped us finish our kitchen. This guy is one of the best, honest, and most hardworking contractor we have ever worked with. If you want reliability, great service, and great communication then he is your guy."

Retaining Wall Installers FAQs, answered by experts

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.

The lifespan of a retaining wall varies based on its material, installation quality, maintenance, and local climate, with an average range of 20 to 100 years. Retaining walls made from durable materials like concrete, stone, and brick generally last a minimum of 50 years. Concrete walls typically last between 50 and 100 years, while brick can last for over a century in ideal conditions. Timber retaining walls can last from 20 to 40 years, depending on the wood quality, and pressure-treated wood walls average around 30 years. It is important to note that a retaining wall can fail prematurely if it was poorly constructed, for example, with inefficient footings or without necessary rebar reinforcements.

Installation typically takes 1-2 weeks, depending on the wall’s size and site conditions.

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.

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.
