Get matched with top retaining wall installers in your area

A well-built retaining wall can absolutely boost home value. By carving out level space, preventing erosion, and giving your yard a clean, layered look, you raise both curb appeal and usable square footage. Home appraisers estimate a 100% to 200% return on the money you spend on building a retaining wall, especially when you choose durable materials and a design that complements the house.

Material and craftsmanship dictate how long a retaining wall lasts. Expect five to 20 years from wood, 20 to 100 from metal, 50 to 100 from concrete, and up to 200 from stone. Choose quality materials, hire an experienced installer, and schedule routine maintenance, and you’ll squeeze the maximum life out of any wall.

Yes, retaining walls require a drainage system. Without proper drainage, water builds up behind the wall and can push it forward or crack the blocks. Most pros add gravel trenches, perforated pipes, and weep holes to move rainwater and groundwater away. This simple step relieves pressure, protects the foundation, and keeps the surrounding soil in place.

Most retaining walls go up in one to three weeks. Crews start by prepping and grading the site, then pour or set footings, stack the blocks, and finish with backfill and clean-up. Bad weather, complicated terrain, or permit holdups can stretch the schedule, but an experienced contractor will build slack into the timeline and keep you informed.
