How to hire the right way
Run your wall through the free calculator. You get a base width, the factors of safety, a materials takeoff and an installed cost range, so you walk into every conversation knowing the numbers.
Tall wall or a surcharge means you need a licensed engineer for a stamped design before a contractor builds it. Shorter walls on good soil usually just need a good installer. We point you to the right one.
Collect two or three quotes and check them against the calculator's cost range. A fair bid lines up with the face-area estimate for your material, plus drainage and any reinforcement.
What to ask every retaining wall contractor
- ✓Ask for a drainage detail: drain rock, perforated pipe to daylight, and filter fabric. This is the number one thing that fails.
- ✓Confirm the base is buried below the frost line and sits on a compacted crushed-stone pad.
- ✓For any wall over 4 ft, or with a driveway or slope above it, ask who stamps the engineered design.
- ✓Get the permit responsibility in writing before work starts.
- ✓Check licensing, insurance, and a few local references for walls at your height.
