What do retaining walls services include?

Retaining walls services include all the necessary tasks to build a sturdy and attractive retaining wall in your outdoor space to prevent erosion. Your hired retaining wall contractors can assess the site, help you design the retaining wall if you don’t have a design ready, then build the wall. 

Assessing the site

The first step in retaining wall construction is taking site measurements. Your Tasker can consider distinct site features, like if the wall will be placed on a slope and if the site gets a lot of rain or snowmelt. The retaining wall builders can also recommend the appropriate design and materials to suit the site’s measurements and features. 

Designing the walls

If you don’t have a design already, a local retaining wall contractor can help you make one. Some local landscape retaining wall contractors can provide you with not just any retaining wall design, but one that conforms with established zoning laws and safety and industry standards. The design can also have the aesthetic elements you want and be sturdy enough to prevent soil erosion in your property. Yes, you can have all this while keeping within your budget! When you post a task, specify your budget and get offers from retaining wall contractors near you. 

Getting permits

The next step is to get permits for the design and build. Your Tasker can obtain the required permits from the relevant authorities like your Homeowner’s Association, City Planning Department, or other federal jurisdiction. Note that some Taskers may charge extra for getting these permits. Even as construction and zoning laws vary from state to state, don’t worry; Local retaining wall installers know how and where to get the appropriate permits. 

Preparing for the build

Your Tasker can get the materials and prepare the appropriate tools. Whichever type of retaining wall you want to be built—brick, concrete, concrete bag, wood, or natural stone—your Tasker can get the right materials! Your Tasker can also make sure the materials and tools are of the right specification, quality, and amount. Then, they can turn over any leftover materials after the build.

Building the retaining walls

Your hired Taskers can do the retaining wall installation or construction once they’re ready with the design, permits, and materials. They can build your retaining wall as per the drafted design, so there are no surprises. The result could be an aesthetically pleasing yet functional wall that can protect your property from soil erosion. The Tasker can execute the design, whether it’s a retaining wall made of wood, concrete, hollow blocks, cement bags, or boulders. They’ll use the appropriate tools, procured materials, safety equipment, and techniques. 

Finishing touches

Your Tasker can apply any finishing touches or embellishments on the retaining wall design as required. This can include installing capstones on stone walls, creating gradual step-downs or turning-in sections, backfilling, or installing greenery and other embellishments. Don’t forget that you can also have other features like privacy screens or outdoor blinds installed.
