Retaining Walls That Hold Up for Decades
A retaining wall is one of the hardest-working features on any property. It holds back thousands of pounds of soil, manages water runoff, and turns unusable hillsides into level yards, patios, and garden beds. At All American Lawn & Landscape, we build retaining walls that are engineered for Dutchess County's challenging terrain -- not just stacked blocks on bare dirt.
Owner Evan Turenchalk evaluates every retaining wall project on site. He assesses the soil type, slope angle, drainage conditions, and load requirements before recommending a wall system and providing a detailed written estimate. Our crew handles the full scope: excavation, base preparation, compacted gravel footing, wall construction, backfill, drainage pipe installation behind the wall, and final grading.
Whether you need a small garden wall to define a planting bed or a six-foot structural wall to terrace a steep lot in Hopewell Junction, Wappingers Falls, or anywhere in Dutchess County, we build it to last through decades of Hudson Valley freeze-thaw cycles.
Retaining Wall Options
We build every type of retaining wall used in residential and commercial applications across the Hudson Valley.
Segmental Block Walls
Manufactured concrete blocks that interlock for strength and come in a range of colors and textures. The most popular residential choice for walls up to six feet tall in Dutchess County.
Natural Stone Walls
Fieldstone, bluestone, and granite walls that blend with the natural landscape. Ideal for rustic properties and historic homes common throughout the Hudson Valley.
Boulder Walls
Large natural boulders placed and stacked to create a rugged, organic look. Best for informal terracing and properties with existing rock outcroppings.
Timber Walls
Pressure-treated landscape timbers for shorter walls and garden terracing. A cost-effective option for walls under three feet with lighter soil loads.
Gravity & Reinforced Walls
Walls over four feet that require geogrid reinforcement, engineered backfill, and proper drainage to safely handle the lateral earth pressure on steep Dutchess County slopes.
Terracing Systems
Multiple tiered walls that step down a steep slope, creating level planting beds or usable lawn space at each terrace. Common on the hillside properties found throughout East Fishkill and Beekman.
Why Most Retaining Walls Fail
The number one reason retaining walls fail in Dutchess County is water. When water builds up behind a wall with no way to drain, the hydrostatic pressure pushes the wall forward until it bows, cracks, or collapses entirely. We see this on properties throughout Hopewell Junction and Fishkill where previous contractors skipped the drainage step.
Every retaining wall we build includes a perforated drain pipe behind the base course, wrapped in filter fabric and surrounded by clean washed gravel. This drainage layer runs the full length of the wall and daylight to a discharge point, ensuring water never builds up behind the structure.
- Compacted gravel base -- minimum 6 inches deep, leveled to within 1/8 inch
- Perforated drain pipe behind every wall, regardless of height
- Clean washed gravel backfill -- never clay or excavated soil
- Geogrid reinforcement on walls over 3 feet tall
- Proper batter (setback) on each course for structural stability
- Cap stones adhesively secured to prevent shifting
Retaining Wall Costs in Dutchess County
Retaining wall costs depend on the wall type, height, length, site access, and soil conditions. Here are typical installed prices for residential retaining walls in the Hudson Valley:
- Segmental block walls (under 4 ft): $25 to $45 per square face foot. A 50-linear-foot wall at 3 feet tall typically runs $4,000 to $7,000 installed.
- Natural stone walls: $35 to $65 per square face foot. Material cost is higher, but the aesthetic blends well with Dutchess County's natural landscape.
- Boulder walls: $25 to $50 per linear foot depending on boulder size and availability. Local fieldstone keeps costs lower than imported stone.
- Walls over 4 feet (engineered): $50 to $85 per square face foot. Geogrid, deeper excavation, and potential permit requirements add to the investment.
Rocky Dutchess County soil can increase excavation time and cost by 15-25 percent when ledge rock or large boulders are encountered during base preparation. Evan identifies these risks during the free site assessment so your estimate reflects actual conditions.
Our Retaining Wall Process
Site Assessment
Evan inspects the slope, measures elevation change, checks soil conditions, and identifies drainage needs. You receive a detailed written estimate with material options and timeline.
Excavation & Base
We excavate the wall trench, compact the sub-grade, and install a level gravel footing. This is the most critical step -- a poor base means a failed wall.
Wall Construction
Block-by-block or stone-by-stone construction with proper batter, drainage pipe, gravel backfill, and geogrid reinforcement where required.
Backfill & Finish
Final backfill and compaction behind the wall, cap stone installation, topsoil restoration, and site cleanup.
