These guys are GREAT! Fast, no hassle, precision work, friendly, great price, exceeded expectations! I went from quote to completed job in ONE WEEK. They used the... read more river stones I already had AND used their own drain piping and geo barrier for drainage behind the blocks, and then even used the excavated dirt to level my sloped lawn! Absolutely fantastic experience. I'd giv3e 10 stars if I could. One FYI to residential homeowners - the equipment was larger than I had expected. I had gotten my neighbor's consent to bring ABC's equipment across their yard, and the tracks tore up the lawn pretty badly because it had just rained. ABC leveled everything when the job was done, and even reinstalled their fence posts and panels that had to be removed in order to get the equipment inside, so I ended up buying them grass seed, fertilizing and watering their lawn, and offering to re-stain their fence in order to make nice. All is well, just be aware that for residential jobs, they use some fairly heavy equipment. Detailed testimonial: I'd been stalling on getting a retaining wall in my backyard because it was going to be crazy expensive. BUT THEN my neighbors decided to replace the fence between us, and I suddenly had ONE WEEK to install a retaining wall between my yard and their new fence. Weekend before: asked for a quote ASAP MONDAY morning: company owner Joel came out and personally surveyed the site, gave me a VERY reasonable quote, and clearly spelled out the next steps. TUESDAY: an 18-wheeler pulled up with the skid steer and backhoe and got them into position. Then another showed up with all 25 blocks - 2.5 tons each WEDNESDAY and THURSDAY: excavation, block laying, drainage, levelling FRIDAY: final blocks installed, cleanup, sign-off, DONE! All done in time for my Friday night kegger, WOOT! Fully recommend. 🙂
