"My husband and I wanted to have our old chain linked fence replaced with a 6ft. Vinyl privacy fence. I always believe you should do some research to find the best possible company for the job . After getting estimates from multiple contractors, we chose AG Construction. We're so happy that we did ! We met with Alex and discussed in detail everything that needed to be done. ( removing & disposing of the old chain link fence, old wooden posts, overgrown shrubs, and left over cinder & patio blocks ) The crew began working in the morning and we're done with the installation ( 260 ft. of vinyl fencing ) & cleanup by late afternoon. They took care of everything ! They were professional and worked very efficiently. We are extremely satisfied with the work they did. I give AG Construction a "10" for the quality of work and the price. Don't hesitate to call AG Construction for your next project"

Retaining Wall Installers questions, answered by experts

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.

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.

Yes, you can use cinder blocks for many purposes, including retaining walls, foundations, garage walls, and fences. Building a cinder block retaining wall costs between $60 and $200 per linear foot, including materials and professional labor. For a 30-foot-long retaining wall, the cost ranges from $1,800 to $6,000.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.
