"Rodney went above and beyond to communicate with us, and ensure that we were satisfied with the end results. His team is friendly, meticulous, and also clearly dedicated to making sure the work was beautiful. Our neighbors continue to say how our front wall looks like a piece of art. I really appreciate how Rodney communicates as well. He encouraged us to text him with any questions and came to the site often to meet with us to make sure we were partnering all along the way. And as a woman who works from home, I felt really respected by Rodney and the workers while they were here - which isn’t always the case as I know all women have experienced. I would highly recommend Rodney and his team."

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

Did a beautiful job re-laying cobblestones, and cleaning up perimeter areas and boundaries with flower beds. Crew of 3 worked hard for a day and a half. Very flexible as our ideas about certain details of the job developed as the work went on."

FAQs for retaining wall installation projects in Concord, NH

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. The creosote treatment in traditional railroad ties helps resist rot and insects, but proper drainage is essential for maximizing longevity. Regular inspections and prompt repairs of minor issues can help extend your wall's useful life.

Creosote-treated railroad ties can pose health risks if used near edible plants or children's play areas. The Environmental Protection Agency (EPA) notes that creosote may be harmful to humans and wildlife. Many localities restrict or prohibit creosote-treated wood in residential settings. For garden applications, consider alternative materials like recycled plastic composite ties or lumber treated with more garden-friendly preservatives.

The ideal drainage solution depends on your specific site conditions and wall height. For most residential applications, a combination of gravel backfill and perforated drain pipe works effectively. 

A complete drainage system costs between $2,100 and $6,500, though basic solutions start at $500. Proper drainage prevents water pressure buildup behind your wall, significantly reducing the risk of failure and extending its useful life.

For walls under four feet tall on relatively flat terrain, you can proceed without engineering services. However, walls exceeding four feet, those on steep slopes, or projects with unusual soil conditions require professional engineering input. 

A structural engineer can design appropriate footings and reinforcement to ensure your wall safely handles the lateral soil pressure it will face.

Railroad tie retaining walls start at $15 to $25 per square foot, with most projects averaging $25 to $30 per square foot, depending on complexity and site prep. This makes them more affordable than natural stone or concrete block walls initially. 

While vinyl options may cost less upfront ($10 to $15 per square foot), railroad ties offer superior aesthetics and strength. Though they require more maintenance than masonry options, their lower initial cost makes them attractive for many homeowners.
