"M&L Landscaping Construction is absolutely incredible! You will not regret hiring Leo and his team for your project. I first hired Leo for one job, and after seeing the quality, precision, and care in his work, I immediately brought him back for a second. The first project included pavers, a retaining wall with built-in seating, a garden bed, patio/paver installation, fence installation, and a composite deck with stairs. The second project was for my rental property and involved an insurance claim to repair the facade of the house. That work included installing stone veneers on the front of my home, constructing a new deck with a roof, building a stone wall with fencing, and completing a blacktop driveway. What truly sets M&L apart is not just the beauty and craftsmanship of their work, but the professionalism, organization, and integrity behind it. Leo’s team is respectful of your property, punctual, and incredibly hardworking. They take pride in what they do and it shows in every detail—from layout precision to cleanup after completion. Equally impressive is how Leo manages the business side of things. He’s communicative, transparent, and extremely reliable—qualities that are rare to find in the contracting world. He provides clear timelines, fair pricing, and proactive updates, so you always know where things stand. Having worked with many contractors over the years, I can confidently say that M&L Landscaping Construction is top-notch from start to finish. I was so impressed that I even referred my parents for their driveway paver installation—and, just as expected, it came out beautiful. If you’re looking for a trustworthy, skilled, and professional landscaping and construction team, hire M&L Landscaping Construction. You’ll be glad you did!"

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

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.

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

Even if you think you know how to build a retaining wall theoretically, doing the actual work is a completely different story. There are lots of nuances in building retaining walls, and the slightest oversight can compromise their integrity. Therefore, we recommend you hire a pro to build, repair, or replace retaining walls.

Vinyl retaining walls are often the least expensive type of retaining wall, at $10 to $15 per square foot. This budget-friendly material is lightweight and durable, but it doesn’t have many decorative options. Untreated timber and railroad ties are the next step up, and start at $15 to $25 per square foot, respectively. High-end steel or natural stone tend to be the least wallet-friendly, but they’re extremely durable and come with a high-end look.

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.
