"These guys are amazing!! The crew that came to do the work at my house were punctual, knowledgeable and efficient. I hired Neel Outdoor Works to install a brick wall and platform for a wood burner and my experience couldn’t have been better. The timelines for material drop off and execution were not only upheld, but were also communicated clearly which has been hard to find dealing with contractors. When the crew arrived to do the work they were able to explain everything that was happening, how long it would take, and precautions to take while the components cured. They finished ahead of schedule and cleaned up so well that it didn’t look like anyone had been there. These guys are absolute professionals in all aspects and I will recommend them to anyone that needs work done."

"Owner showed up with a small crew and a crazy new piece of equipment. Excavated down below my foundation and to the septic tank. Came into the basement and jackhammered the floor. Removed all the old terracotta pipe inside and out. Installed all new PVC pipe all the way down to the septic tank. Put gravel down to protect the new pipe. Poured concrete in the basement to close the floor back up. Only took one day to get the new pipe in. Came back the next to close the ground and floor up. Great experience, basement no longer smell like sewage."

"I hired C&W to replace a collapsed retaining wall. Pete came up with a solution of boulders that enabled me to keep the existing fence line with a flat yard above. His price was fair, he did the work in a timely manner, and the aesthetics exceeded my expectations. It was a challenging project with lousy access and a difficult slope. I live on a golf course in the South Hills and while I was watering my replaced grass, three different players offered me compliments on the results. I am someone that pushes hard for top quality at a competitive price and I definitely feel that I received that here. I encourage anyone with a project such as this to entertain a proposal from C&W Works. I would recommend C&W Works without hesitation. CAR"

"Brandon and his team showed up day to start the work a few days before I asked them to begin which was a plus because our concrete church ramp needed repaired soon for safety reasons. The work was completed with professionalism and did not interfere with our church services. Brandon was also easy to contact and returned calls and text messages in a timely manner"

"The owner takes exceptional pride in his work. The finished project, a retaining wall and replacement of a wooden deck with a patio using Beacon Hill pavers is outstanding. Would hire them again for similar projects in a heartbeat."

Retaining Wall Installers questions, answered by experts

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.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

Generally, a railroad tie retaining wall consisting of a single line of ties should be between 3 and 4 feet tall—and the height often tops out at around 6 feet. You can go taller, but you may need additional footings and reinforcements, including a second layer of railroad ties to support the added weight of the soil it’s holding back.
