Swapping Out An Old Timber Retaining Wall

August 03, 2017

Project Description:

The homeowner needed a renovation to their sloped backyard.  They wanted the old, worn out timbers to be removed and replaced with block retaining walls, for a fresh, functional, updated space.  The steps were also made of timbers, and were rotting which was a safety hazard.  These would be replaced with Chilton stone steps for a more durable, safe, step for the high traffic area.  The walkway on the side of the house was torn up, and the pavers were reused in the new layout. The planted areas were overgrown and filled with weeds, so mulch and a weed barrier fabric was included in the project.  New sod replaced the patchy grass to provide a lush, green, usable space.
