"We selected Hardscapes in late July 2020, and they were able to do the work in January 2021. We knew upfront they had a waiting list. They built a 70 feet long retaining wall as the existing one was railroad ties and it was failing. The new wall looks excellent. It took about a week to do, and it was rough work since it had been raining consistently. I also requested them to redo our stairs in the same area. While I should be most impressed with the wall as it is fabulous, I really love the stairs. It was excellent work. The gentlemen working were all very nice and did a great job cleaning up every day. The neighbors even complimented on how thorough they were with clean up. The owner came to the site every day staying as long as was necessary each day managing the project and reviewing work that had been done and tweaking if he thought it was needed. He was also very easy to contact and responsive if he wasn't on site. The owner appears to take pride in his work which is a very positive attribute. While he was here since we were very happy with the end product we also had him quote us on some other possible projects. In short, while there is a decent wait time, it is definitely worth it."

"Diego went above and beyond to help transform our backyard into a larger, more beautiful space for our family. From start to finish, he was professional, hardworking, and paid close attention to detail. His knowledge and dedication really showed in the final result.

"After receiving quotes from other contractors. We requested a quote from TDK Landscapers to demolish and construct an L shaped handicap ramp 25 ft with a 5x5 ft landing and additional 8 ft ramp to the driveway. Tyler the owner contacted me the same day and arranged to meet the next day for a quote. He assessed the project, provided an amount and was able to scheduled us for the next week. With a great first impression we agreed. Day 1, Demo and removal, day 2, framing and supports, Day 3 deck boards applied (with SCREWS not nails). The project was finished with complete satisfaction . Very nice hard working and enthusiastic young man. We will request him for our future projects and refer him to others. Randy & Kathy homeowners."

"They installed the irrigation system, laid the sod, planted all my shrubs, and put down mulch for my new house. Irvin was exceptionally easy to work with and knowledgeable. He came back several times after the install to insure sprinkler heads were adjusted and covering properly. And his prices were very reasonable. He also ran my downspouts to the street."

"Several months ago we decided to remove a very old garden tub and replace it with a walk-in shower. We also had a new vanity top and new fixtures along with a new tile floor. I highly recommend Nicholas Tile & Bath. It was an amazingly smooth process Tom and his crew were great to work with. We had no problems from start to finish. Highly recommend for any tile or bath update."

"I hired Alex for the job of installing a large 72" recessed fireplace into the wall of my master bedroom. Initially I was going to go with Touchstone Sideline recessed electric fireplace. After calling roughly 5-7 surrounding fireplace businesses and spending over 5 hours on the phone to get continuously rejected for project and timeline, I got in touch with Alex at Queen City Fireplace. He came out the same day to look at the space, and assess the job. He recommended Dimplex fireplace instead, and I'm SO GLAD he did. Within 3 days the final job was done, and the fireplace couldn't be more Spectacular! Alex was punctual, knowledgeable, experienced, and worked diligently to get the job done RIGHT! He was a breathe of fresh air compared to all other companies. I will be using him for all future needs, and would ***Highly recommend for all indoor/ outdoor Fireplace installations. Thank you Queen City Fireplace!"

Retaining Wall Installers FAQs, answered by experts

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

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.

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like. 

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.

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.
