"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

"Mr. Torres was great with all the work we had done. We went to his office where we picked out the color stones for our brick steps and paver walkways. He was extremely helpful with suggestions and patterns. In the middle of the job I asked for an estimate for the side of our house for a walkway and he was able to do that as well as the initial work. The price was very fair and we were very happy with it, we had another estimate for the work and it was astronomical. I would definitely recommend this company and I will be going back to him for future work."

"John did phenomenal work on my job, and went the extra mile to make sure the quality was top-notch. I have a few friends who are professional carpenters, and they were very impressed with the job he did; he never cut corners and made sure the deck was solid, well-supported, and safe. We are thrilled with how the deck came out and would most definitely use Timeless again for future work."

"Our experience with Paragon was generally positive and we'd recommend this contractor without reservation. The business arrangements were clear and Paragon operated with integrity and flexibility. Our crew was competent, respectful of our home, friendly, and took pride in doing careful and quality work. Paragon quickly responded to customer feedback and strived for customer satisfaction throughout the project. The sources recommended by Paragon for wall tile, wood flooring, counter granite, cabinet hardware, and plumbling fixtures all provided superior service and extended contractor pricing. Our remodeled kitchen and powder room are key features of our traditional 1926 house and significantly enhance the home appearance and property value."

Retaining Wall Installers FAQs, answered by experts

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

Options include concrete, stone, brick, and wood, tailored for specific design needs.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.

DIY is possible for small projects. Professional installation ensures structural integrity and durability for larger walls.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.
