Wonder Walls — Retaining Walls in Carlisle, WA

Helpful and friendly staff and services provided highly appreciated. Got wrong post they not only accepted swap but considered the excess amount due to differences in rate for post.

All good until something goes wrong, then no ownership is taken of any bad workmanship. Acknowledge the problem exists, but refuses to do anything about it. Kept us waiting months with promises, only to tell us they will not rectify, leaving us with legal proceedings as our only option. I strongly recommend using a different company.

I have had Wonder Walls help me scope, supply and install two retaining walls over a span of 3 years. Both times, I’ve had impeccable communication, discussion and the quality of the work had surpassed expectations. Thank you Anthony for all your help!

We have used Wonder Walls for retaining walls on both sides of our property and we are extremely pleased with the results. The guys on site kept the noise and mess to a minimum and the end results were better than we ever expected. We would not hesitate to use Wonder walls again and recommend them to anybody.........

Paul was meticulous with checking that the job was done right, from the quoting process, to council approval, to installation. He came on site many times to check progress and answer questions and was always available over the phone. Price was excellent - much better than other quotes. Valerie and Lance were also excellent providing support. The installation guys were cheerful, hard workers who didn't mind taking the time to explain what they were doing so I could understand. Product looks great and I couldn't be happier with the result. Seriously good business, guys - well done and keep up the good work.
