If you’re tired of your old plastic or metal edging but aren’t sure whether you need to remove it first, you’re not alone. Many homeowners wonder if decorative concrete borders can be installed right over existing edging, or if a full replacement is the smarter choice.
The short answer: it depends on what’s already there and what condition it’s in. In most cases, professional installers like AE Landscape Borders will remove old edging before pouring new concrete curbing to ensure a clean, long-lasting result. Here’s what you need to know.
Why Removing Old Edging Usually Makes Sense
Decorative concrete edging works best when it’s installed directly against stable soil or turf. Installing over old edging can create problems down the road. Plastic and metal edging often shifts, sinks, or breaks apart over time, and if your new concrete border is poured on top of unstable material, it won’t have the solid foundation it needs.
Old edging also creates an uneven surface. Concrete curbing is typically 4 to 6 inches deep, and if there’s existing material in the way, the new border may not sit flush with your lawn or garden bed. This can lead to poor drainage, an awkward appearance, and maintenance headaches.
Most professional installations involve removing the old edging entirely. AE Landscape Borders handles this as part of the process, so you don’t have to worry about digging it out yourself. The result is a smooth, even concrete border that will last for decades with minimal maintenance.
When Can You Install Over Existing Edging?
There are rare situations where installing over old edging might be acceptable. If you have a very shallow border material that’s completely flush with the ground and hasn’t moved or deteriorated, a professional installer might be able to work with it. But even then, most experts recommend removal to avoid future issues.
If the existing edging is buried brick or stone pavers that are level and stable, those might stay in place depending on the design. However, flimsy plastic strips, bent metal edging, or anything that’s already coming apart should always come out before new concrete is poured.
Choosing the right border pattern and color also depends on having a clean foundation. Once the old material is removed, you’ll have full flexibility to select from patterns like Missouri Flagstone or Slate and colors like Smokey Quartz or Charcoal.
What Happens During a Replacement Installation?
When you schedule an install with AE Landscape Borders, the crew will assess your existing edging during the onsite estimate. If removal is needed, it’s typically handled the same day as the installation. The old material is pulled out, the trench is cleaned and prepped, and then the new decorative concrete curbing is poured in place.
Most residential projects are completed in a single day. Larger properties might take two days, but either way, the process is faster and cleaner than you’d expect. The concrete will be walk-on firm within hours, though full curing takes up to 28 days.
Removing old edging also gives the installer a chance to address other common issues, like relocating sprinkler heads, working around tree roots, or adjusting for proper drainage. These details make a big difference in how long your new border lasts and how well it performs.
Is Replacement Worth the Extra Effort?
In almost every case, yes. Decorative concrete borders from AE Landscape Borders come with a lifetime warranty, which means you’re investing in a solution that won’t need to be replaced again. Plastic and metal edging typically need replacement every few years, but professional concrete curbing is built to last.
Replacement also gives you a chance to improve your landscaping layout. You can adjust curves, straighten lines, or add borders around new garden beds. The finished product looks cleaner and more polished than trying to layer new material over old.
If you’re concerned about cost, keep in mind that concrete edging reduces long-term maintenance. You’ll spend less time trimming, fewer hours dealing with washouts, and you won’t be replacing cheap edging every few seasons. An onsite estimate will give you exact pricing based on your property’s specific needs.
