For over 10 years, Porter's Lawn Service has helped homeowners and businesses in Cottleville, St. Charles, O'Fallon, Wentzville, and the greater St. Louis area tame sloped lots and reclaim their yards. A well-built retaining wall does more than hold back soil-it controls erosion, protects your property from runoff, and turns a steep hillside into level, usable outdoor space.
Materials & design options
Engineered block, natural stone, and boulder walls sized for your slope and style. Terracing, raised beds, and clean edges that solve a grading problem and look great doing it.
Function & lasting value
Control erosion, redirect runoff away from your foundation, and add level, usable square footage-a retaining wall that protects your property and boosts curb appeal at the same time.

Frequently Asked Questions
We build retaining walls in engineered concrete block, natural stone, and large boulders. The right choice depends on the height of the wall, the look you want, and how your yard drains. We will walk your property and recommend the material that fits both the function and the style of your St. Louis or St. Charles County home.
Yes. A properly built retaining wall holds back soil on sloped lots, controls erosion, and redirects runoff so water stops washing away your yard or pooling against your foundation. We pair every wall with the correct base preparation, gravel backfill, and drainage so it protects your property for the long term.
Longevity comes from what you do not see. We excavate and compact a solid base, install proper drainage and backfill, and follow sound engineering for wall height and batter so the wall resists soil pressure. Cutting corners on the base or drainage is the most common reason walls fail, and we never do.
Absolutely. Terracing a steep slope turns unusable hillside into level, functional space for patios, gardens, or play areas. Walls also create built-in raised beds and clean edges that add real value and curb appeal. Contact us to talk through what your yard could become.
Retaining wall projects are priced per project because cost depends on wall height and length, material, site access, drainage needs, and how much excavation is required. We offer free estimates- contact us or call (636) 293-9306 for a personalized quote.
