"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."

Customers say: True professional

"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."

"Undertaking a large investment in a new concrete driveway can be daunting. After soliciting several bids - I selected Keo because he immediately gave me comfort that he was someone I could trust, and I’m glad I did, because he did an exceptional job. He and his crew were very professional and personable; they have clearly honed their craftsmanship over many years. I highly recommend Keo for your next stone or concrete home or commercial improvement."

"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"

Retaining Wall Installers questions, answered by experts

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.

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.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.
