Get matched with top retaining wall installers in Black Diamond, WA

"This is the second time that we have used NGL. First time was for our patio. They did an amazing job again. We removed a diseased hedge that was on two sides of our house. NGL was hired to expand our backyard including a privacy fence. They installed a beautiful retaining wall with fencing to match the rest of our yard. We have already received numerous positive comments about the new wall and fence. We are thrilled. They also installed a sprinkler system and new sod. Throughout the process they ensured our needs were met and made many helpful suggestions just as they had with the patio. Their work is exceptional and their skill is outstanding. They are a fantastic team. We have already been asked by 5 different people walking by for info on the company."

"I needed safe, hardscape stairs installed down a steep retaining wall after near miss accidents on the existing slippery and open cedar steps. Doug was responsive and kind and clear as we designed the stairs within budget. Gus and his crew were amazing, showed up with great attitudes, worked through SNOW, protected my existing plants, cleaned up the work area, and finished early! I am very happy with the end result and canâ t wait to work with them more!"

"Marco & company did nice work on a somewhat customized block retaining wall on a compound slope between our house and the neighborsâ house. Iâ m planning to use them on other projects."

"French drain installation along a retaining wall (75 yards). Thomas who handled the sales end of things was friendly and responsive. The crew showed up on time. They were hard working and receptive of customer feedback. They first removed the ivy that was obstructing the work area and then completed the trench on day 1 which uncovered some of the unwelcome water sources. A legacy footing drain was plumbed directly into the main french drain pipe. Perpherated pipe was dropped in on Day 2 followed by river rock, catch basins, and 3 ft dry well installation. Cleanup was done thoroughly. I would hire them again in a heartbeat."

"They went to extra trouble to ensure we had the pavers we wanted despite the manufacturer having closed out the item. The two-man work team did an exceptionally good job and made very nice adjustments needed to fit a pre-existing retaining wall boundary. Overall, very pleased with their work."

"Venly and Sam and the entire team were an absolute joy to work with. They installed a new driveway, excavated and built a stone retaining wall and put up a new privacy fence.

The crew was always on time and very were respectful and kind. I highly recommend Island Concrete."
