"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"They stuck to timeline perfectly.  Did work in a respectful manner.  Abided by town ordinances regarding hours of work.  Were respectful to all neighbors concerns and even managed town concerns and called me when needed. They were as respectful with their staff as they were with me a s a client.  They recommended and prepared land for seasonal and weather conditions so work was most efficient in spring.  They were genuinely concerned about my property as if it was their own and made only reasonable and sound recommendations.  Nothing to just "bring them more business".  Great communication and pacifying any apprehensions in a respectful way. I'd use them again anytime for any project.

"Torres Contracting helped us with installing a new sidewalk, paved driveway (with specific requirements re design), a side area for the garbage cans and cement for part of a back porch. We hired Tony and Torres Contracting after a lot of due diligence. Tony is a busy man and communicates efficiently by text. He and his daughter addressed all my questions and concerns by phone, email and text. Further the team was excellent- including Juan, Edwin and several others— honest, technically very good and incredibly hard working especially in very hot weather! Torres Contracting was fair on pricing, the project was done in a la efficient manner and the work product is excellent. I am grateful we hired Tony and his company and I highly recommend them as a trustworthy company that does excellent work! Bottom line: Responsive, excellent work, fair price, active communication to understand expectations! 5 stars ⭐️⭐️⭐️⭐️⭐️"

"Work performed on designer block berm wall was outstanding. Ran into an issue where they started installing the wrong type of designer block then what was originally requested. I did not notice until after the installation started. I brought it up to the owner/supervisor and he made the correction with no resistance and no additional cost to me. The project came out great and I am looking to have them perform more landscape design projects for us in the near future. FEI has been our general landscape maintenance contractor for 15 straight years. The edge, in my opinion, FEI has over any other landscaper that I could bring in is their personable and organized office manager. Her responsiveness to any needs, or concerns, which I may have regarding my lawn care service is handled professionally and efficiently."

Retaining Wall Installers FAQs, answered by experts

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.

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.

Regular inspection for issues like cracks or leaning and ensuring drainage stays clear.

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.
