Twinside Retaining — Retaining Walls in Landsdale, WA

Cannot speak highly enough about the level of service we received from this company. They responded to our online inquiry quickly, and had a contractor contact us, and visit the site to quote within 24 hours. Risto Sepp the contractor, was amazing. He provided a fair and reasonable quote and then completed the job on the dates and timeline promised. Risto was professional, courteous and skillful in all aspects of the job, and we are very happy with the finished product. We would have no hesitation in endorsing Twinside and their contractor Risto to anyone seeking the construction of a retaining wall.

Amazing result. I am extremely impressed with both the Twinside product and our installer, Risto Sepp. He visited us to measure and quote which was very reasonable and included supply of the panels and posts. Risto is hard-working and his attention to detail exceptional. We now have a smart, attractive and straight retaining wall. I would strongly recommend his services.

Amazing product and team effort in installation! We had our large backyard transformed by Leon and the team and we could not be happier! From start to finish these guys were an absolute pleasure to deal with and nothing was ever an issue for them! We will be using them again in the future and would highly recommend them to anyone! Thanks again Advance

Excellent service and product. My wife and I wanted to retain a 12m long garden flower bed. Fantastic advice given. We picked up and installed the concrete panels and posts ourselves and had a great time due to an excellent and reliable product. Has added value to the home. We would highly recommend A++++++++ Mark and Barbara.
