Quick question. We did a small retaining wall and some landscaping for a client. I'll briefly describe the job. Please tell me what you would charge. I'll post later what we charged. The customer seemed to think our price was a way too high - I just want to make sure that we were not out of the park with our price. The job: Build a 70' long retaining wall of the castle rock style wall stone (like they carry at Home Depot/Lowes). The wall was two blocks high (for a total height of 8"). We used approx 150 blocks. We then had to back fill (by hand) the area behind the wall with 7-8 yds of topsoil to build bermed planting area for an installation we later put in. Total material cost for this portion of the job was about $550. Thanks for your help.
